INTRODUCTION TO THE INTERNET
Time Allowed: Three Hours Max. Marks: 50
Note: Attempt Five questions in all, selecting at least One question from each section. The
Fifth question may be attempted from any section. All questions carry equal marks.
SECTION-A
1. What is network bandwidth? What is difference between bandwidth and speed? How network
bandwidth is measured?
Ans: What is Network Bandwidth?
Network bandwidth means the maximum amount of data that can travel through a
network or internet connection in a given amount of time.
In simple words, bandwidth tells us:
“How much data can be transferred at one time.”
You can think of bandwidth like a road or highway.
• If the road is narrow, only a few vehicles can pass at once.
• If the road is wide, many vehicles can travel together smoothly.
Easy2Siksha.com
Similarly:
• Narrow bandwidth → less data travels at once
• Large bandwidth → more data travels at once
So, bandwidth is the capacity of a network connection.
Simple Real-Life Example
Imagine you are filling a water tank using a pipe.
• A thin pipe carries less water.
• A thick pipe carries more water.
Here:
• Water = Data
• Pipe width = Bandwidth
The thicker the pipe, the more water can flow at one time.
In the same way, higher bandwidth allows more data to move through the network.

Approximate Bandwidth
Easy2Siksha.com
Slow mobile internet
2 Mbps
Home broadband
50 Mbps
Fiber internet
100 Mbps – 1 Gbps
Office high-speed network
10 Gbps
What is Speed in Networking?
Now let us understand speed.
Network speed means:
“How fast the data travels from one place to another.”
It refers to the rate at which information reaches the destination.
For example:
• If a file downloads quickly, the internet speed is high.
• If buffering happens while watching YouTube, the speed may be low.
Difference Between Bandwidth and Speed
Many students think bandwidth and speed are the same, but they are different.
Easy Example
Imagine a highway:
• Bandwidth = Width of the road
• Speed = Speed of the cars
A road may be very wide (high bandwidth), but cars can still move slowly due to traffic or
signals.
Similarly:
• High bandwidth does not always mean high speed.
• Actual speed depends on network congestion, server performance, latency, and
other factors.
Main Difference Between Bandwidth and Speed
Bandwidth

Also measured in bps
Related to maximum limit
Related to actual performance
Another Simple Analogy
Suppose two buses are traveling:
Bus A
• Small bus
• Moves very fast
Bus B
• Large bus
• Moves slowly
Here:
• Bus size = Bandwidth
• Bus movement speed = Network speed
A bigger bus can carry more people, but that does not mean it moves faster.
Similarly, greater bandwidth means more data capacity, not necessarily faster transfer.
How is Network Bandwidth Measured?
Network bandwidth is measured in:
Bits Per Second (bps)
This means how many bits of data can travel in one second.
Units of Bandwidth

Gbps
Gigabits per second
1,000,000,000 bits
Common Examples
• 10 Mbps internet
• 100 Mbps broadband
• 1 Gbps fiber connection
These numbers show the maximum data transfer capacity.
Visual Understanding of Measurement
1 Kbps = 1 Thousand bits/sec
1 Mbps = 1 Million bits/sec
1 Gbps = 1 Billion bits/sec
The larger the number, the greater the bandwidth.
Why is Bandwidth Important?
Bandwidth is important because it affects internet performance.
Higher bandwidth helps in:
• Faster downloads
• Smooth video streaming
• Better online gaming
• Clear video calls
• Multiple users using internet together
Example of Low and High Bandwidth
Low Bandwidth
If many people use the same small internet connection:
• Videos buffer
• Games lag
• Downloads become slow
High Bandwidth
Easy2Siksha.com
With high bandwidth:
• Multiple devices work smoothly
• HD videos play properly
• Large files download quickly
Factors Affecting Network Performance
Even if bandwidth is high, speed can still become slow because of:
1. Network traffic
2. Weak Wi-Fi signal
3. Distance from router
4. Server problems
5. Hardware limitations
6. Latency and packet loss
So bandwidth alone does not guarantee perfect internet performance.
Important Point to Remember
A very easy line to remember is:
“Bandwidth is how much data can travel, while speed is how fast the data travels.”
Conclusion
Network bandwidth is the data-carrying capacity of a network connection. It tells us how
much information can move through the network in a specific time. It is commonly
measured in bps, Mbps, and Gbps.
Bandwidth and speed are related but different concepts. Bandwidth refers to the maximum
amount of data that can travel, while speed refers to how quickly the data actually moves.
A network with higher bandwidth can handle more users, more devices, and larger amounts
of data efficiently. That is why modern homes, offices, and industries prefer high-bandwidth
internet connections for smooth and reliable communication.

2. What is difference between webpage, website, web browser, web client and web
server? Which hardware and software is required to use internet at home?
Ans: Imagine you are walking into the world’s largest, most magnificent library. It has
billions of books, infinite rooms, and millions of librarians working at lightning speed to
bring you exactly what you want to read.
The internet works exactly like this library. However, because tech experts love using words
that start with "web," it is incredibly easy to get confused. Let’s break down these five
terms—webpage, website, web browser, web client, and web server—using our library
analogy so that it makes perfect sense.
Part 1: The Global Library
1. The Webpage (A Single Page)
Think of a webpage as a single page out of a book. It is one specific document that contains
text, images, videos, or links. When you are looking at an article about space exploration or
a single recipe for chocolate chip cookies, you are looking at a webpage.
2. The Website (The Whole Book)
If a webpage is a single page, a website is the entire book. It is a collection of related
webpages that are all grouped together under one name (a domain name, like nasa.gov or
wikipedia.org). Just like a book has a cover and a table of contents to help you navigate its
pages, a website has a homepage and a navigation menu to help you find its specific
webpages.
3. The Web Server (The Librarian and the Bookshelf)
A web server is a powerful computer that stays on 24/7. Its only job is to store website files
and serve them to people who ask for them. Think of the server as the library's bookshelf
and the librarian combined into one. When you ask to see a website, the web server goes
into its digital files, grabs the correct "book" (website), and sends the specific "page"
(webpage) back to you over the internet.
4. The Web Client (You, the Reader)
A web client is the customer of the web server. In our analogy, the client is you asking the
librarian for a book. In the digital world, a web client is usually your device (your
smartphone, laptop, or smart TV) or the software on that device making the request. If the
server is the one handing out the information, the client is the one asking for it and
receiving it.
5. The Web Browser (Your Reading Glasses)
Finally, we have the web browser. This is a specific type of software—like Google Chrome,
Apple Safari, or Mozilla Firefox. The web browser acts as your digital reading glasses. When
Easy2Siksha.com
the web server sends a webpage to your device, it doesn't send a pretty picture; it sends a
bunch of complicated computer code. Your web browser takes that messy code, translates
it, and paints it onto your screen as a beautiful, readable webpage.
Part 2: Connecting Your Home
Now that we know how the library works, how do we actually build a road from your house
to that library? To use the internet at home, you need a specific combination of hardware
(physical devices you can touch) and software (invisible programs running on those devices).
The Required Hardware
1. An Internet Connection (The Road): First, you need an Internet Service Provider
(ISP). This is a company that physically runs a wire (like fiber optic, coaxial cable, or a
satellite signal) directly to your house.
2. The Modem (The Translator): The internet signal coming through the wire from the
outside world speaks a different language than your home computers. The modem is
a small box that translates the outside internet signal into a digital signal that your
home devices can understand.
3. The Router (The Traffic Cop): While the modem brings the internet into your house,
the router shares it with all your devices. The router takes that one internet
connection and broadcasts it through the air as a Wi-Fi network. It directs the
invisible traffic, making sure the Netflix movie goes to the living room TV and the
video game data goes to the computer in the bedroom without crashing into each
other. (Note: Today, many ISPs give you a single box that acts as both a modem and
a router combined).
4. Your Devices: Finally, you need the physical hardware to view the internet—your
laptop, tablet, smartphone, or smart TV.
The Required Software
1. Operating System (OS): Every device needs a foundational brain to function, such as
Windows, macOS, Android, or iOS. The operating system manages your device's Wi-
Fi connection and talks to the router.
2. Network Drivers: These are tiny, hidden software programs built into your computer
that tell the physical Wi-Fi antenna inside your laptop exactly how to listen to the
router's signals. (You usually don't have to worry about these, as your operating
system handles them automatically).
3. The Web Browser: As mentioned earlier, once your hardware is all connected, you
need a software application like Chrome, Edge, or Safari to actually type in a website
address, request the webpages, and display the information on your screen.
By combining the right hardware to bring the signal into your home with the right software
to translate it, you gain instant access to the greatest digital library ever built!

Ans: 3.(a) What are Spam and Phishing E-mails? Give an Example of Both.
(b) Features and Tools Available in E-mail Service
E-mail has become one of the most important ways of communication in today’s digital
world. People use e-mails for sending messages, documents, photos, notices, office work,
online shopping details, and much more. But along with useful communication, there are
also some harmful and unwanted e-mails that can create problems for users. Two common
examples are Spam E-mails and Phishing E-mails.
(a) Spam and Phishing E-mails
What is a Spam E-mail?
A Spam E-mail is an unwanted or unnecessary e-mail sent to many people at the same time.
These e-mails are mostly advertisements, promotional offers, fake lottery messages, or
unnecessary links.
Spam e-mails are also called junk mails because they fill the inbox with useless messages.
These e-mails are generally sent without the permission of the user.
Simple Example of Spam E-mail
Imagine you open your e-mail inbox and see a message like:
“Congratulations! You have won a free iPhone. Click here now!”
or
“Buy medicines at 80% discount.”
These kinds of e-mails are usually spam messages.
Characteristics of Spam E-mails
1. Sent to a large number of people.
Easy2Siksha.com
2. Mostly advertisements or promotional offers.
3. Unwanted and unnecessary.
4. May contain suspicious links.
5. Fill the inbox and waste time.
Problems Caused by Spam E-mails
Spam e-mails may create many problems such as:
• Waste of internet storage space.
• Important e-mails may get hidden.
• Spread of viruses and malware.
• Disturbance and irritation to users.
What is a Phishing E-mail?
A Phishing E-mail is a fake e-mail sent by cybercriminals to steal personal information such
as:
• Passwords
• Bank details
• ATM PIN
• OTP
• Credit card information
In phishing, criminals pretend to be trusted organizations like banks, online shopping
websites, or social media companies.
Their main goal is to cheat users and steal confidential information.
Simple Example of Phishing E-mail
Suppose you receive an e-mail saying:
“Your bank account will be blocked within 24 hours. Click here and enter your password to
verify your account.”
If you click the link and enter your details, the cybercriminal may steal your banking
information.
This is called a phishing e-mail.

4. Write a note on Google Advanced Search. Write the symbol, meaning and use of
various search operators.
Ans: Imagine you walk into the world’s largest library. It doesn’t just have millions of books;
it has trillions of pages, loose notes, pictures, and video clips scattered everywhere. If you
walk up to the desk and just say "space," the librarian is going to dump a mountain of boxes
on your lap, containing everything from sci-fi movies to NASA documents, perfume
advertisements, and restaurant menus named "Space."
This is what happens when you do a basic Google search. It’s incredibly powerful, but it
often gives you way too much noise when you are looking for a specific signal.
That is where Google Advanced Search comes in. Think of it as a remote control with
specialized buttons that lets you tell the Google algorithm exactly what to look for, what to
ignore, and where to look. You can access this through a built-in menu on Google, or you
can use Search Operators—special characters and words that act as secret keyboard
shortcuts to turn you into a research ninja.
Let’s break down these operators in a way that makes you a master of the digital library.
The Digital Funnel: How Advanced Search Works
When you type a standard query, Google looks for any relationship to those words.
Advanced operators act like filters in a funnel, narrowing down billions of possibilities into a
few perfect results.
[ ALL WEB PAGES (Trillions) ]
\ /
\ " " / <-- Locks in the exact phrase
\ - / <-- Kicks out unwanted words
\ site: / <-- Restricts to a specific trusted
website
\_______/
|
[ PERFECT NEXT-LEVEL RESULTS ]
The Secret Codes: Google Search Operators Explained
Here is a complete cheat sheet of the most powerful operators, what they mean, and
exactly how to use them.
1. The Exact Match Tool: Quotation Marks ""
• Symbol: ""
• Meaning: Search for the exact phrase, in this exact order, without changing any
words.
• Use Case: Normally, if you search for cat training manuals, Google might show you
articles about "how to train a kitten" or "manuals for tiger handlers." If you search
"cat training manuals", Google will only show pages that have those three words
Easy2Siksha.com
sitting exactly side-by-side. It is perfect for finding specific quotes, song lyrics, or
precise book titles.
2. The Excluder: The Minus Sign -
• Symbol: - (with a space before it, but no space before the word you want to block)
• Meaning: Exclude a specific word or phrase from your search results entirely.
• Use Case: Let’s say you are writing a report on the animal Jaguar, but your search
page keeps getting flooded with cars, dealerships, and football teams. You can type
jaguar -car -football. This tells Google: "Show me everything about jaguars, but if a
page mentions a car or football, throw it in the trash!"
3. The Digital Fence: The Site Operator site:
• Symbol: site:
• Meaning: Restrict your search results to one specific website or an entire domain
extension (like .edu or .gov).
• Use Case: If you need reliable scientific data about climate change for a school
project, you might want to avoid random blogs. Typing climate change site:.gov
forces Google to only return results from official government websites. Alternatively,
if you remember reading a cool article about space on Wikipedia but can't find it,
you can search mars rover site:wikipedia.org.
4. The Format Selector: The Filetype Operator filetype:
• Symbol: filetype:
• Meaning: Search only for specific digital file formats, such as PDFs, PowerPoint
presentations, or Excel spreadsheets.
• Use Case: If you are studying for a history test and want to find a presentation to
review, you can search french revolution filetype:ppt. If you want an official
academic paper or textbook chapter, you can search quantum physics filetype:pdf.
Google will ignore regular web pages and only give you downloadable files.
5. The Choice Maker: The OR Operator
• Symbol: OR (Must be capitalized) or the vertical bar |
• Meaning: Search for pages that contain either Word A, Word B, or both.
• Use Case: If you are researching colleges but haven't decided between two paths,
you can search admissions Harvard OR Yale. This gives you pages containing
information about either university, saving you from running two completely
separate searches.
6. The Missing Link: The Wildcard Asterisk *
• Symbol: *
• Meaning: Acts as a placeholder or a "blank space" for a word that you don’t know or
can't remember.
Easy2Siksha.com
• Use Case: If you are trying to remember an old saying or song lyric but forget the
middle, you can type "a * saved is a * earned". Google will automatically fill in the
blanks with "penny" and "penny" to find the correct phrase for you.
Combining Your Superpowers
The real magic happens when you stack these operators together like blocks.
Imagine you need an official report on global warming, but you don't want any long videos,
and you want it specifically from NASA's official site. You can type a super-query like this:
With one short line, you have instructed Google to find an exact phrase, look only inside
NASA's servers, return only clean PDF documents, and banish any video content.
SECTION-C

• Internet interruptions
• Miscommunication
• Lack of attention
• Background noise
• Wasting time
• Confusion about responsibilities
Effective strategies help to:
• Improve communication
• Increase participation
• Maintain discipline
• Save time
• Achieve meeting goals successfully
Effective Strategies for Successful Virtual Meetings
1. Set a Clear Purpose for the Meeting
Before arranging a virtual meeting, the organizer should clearly know:
• Why the meeting is being conducted
• What needs to be discussed
• What outcome is expected
If the purpose is unclear, participants may feel confused and uninterested.
Example:
Easy2Siksha.com
A teacher conducting an online class should clearly mention:
• Topic of discussion
• Learning objectives
• Important tasks or assignments
A clear purpose keeps everyone focused.
2. Prepare an Agenda in Advance
An agenda is a list of topics that will be discussed during the meeting.
It helps participants:
• Prepare beforehand
• Understand the meeting flow
• Stay organized
A good agenda includes:
• Meeting topics
• Time for each topic
• Names of speakers
• Important documents or links
Example Agenda:
1. Introduction
2. Project discussion
3. Problem solving
4. Question-answer session
5. Final conclusion
When participants receive the agenda earlier, meetings become more productive.

The organizer should ensure:
• Stable internet connection
• Working microphone
• Clear camera quality
• Updated meeting software
Participants should test their devices before the meeting starts.
Common Technical Problems:
• Audio not working
• Screen freezing
• Echo or noise
• Poor internet speed
These problems waste time and disturb communication.
Solution:
Conduct a quick technical check before starting.
4. Start and End on Time
Time management is very important in virtual meetings.
Long meetings make participants tired and distracted. A successful meeting should:
• Start on schedule
• Stay within the planned duration
• End with a summary
Respecting time shows professionalism and discipline.
Tip:
For long meetings, short breaks can help participants stay active and focused.
5. Encourage Active Participation
A successful virtual meeting should not become a one-person lecture.
Everyone should get a chance to:

• Speak
• Share ideas
• Ask questions
• Give suggestions
This keeps participants engaged and interested.
Methods to Increase Participation:
• Ask direct questions
• Use polls or quizzes
• Encourage discussions
• Allow chat interaction
When people participate actively, meetings become more meaningful.
6. Maintain Proper Communication Etiquette
Virtual meetings require good online behavior.
Important Etiquette Rules:
• Mute microphone when not speaking
• Avoid interrupting others
• Speak clearly and politely
• Maintain eye contact with camera
• Dress appropriately
• Avoid unnecessary background noise
Good etiquette creates a respectful and professional environment.
7. Keep the Meeting Short and Focused
Many virtual meetings fail because they become too lengthy.
People lose concentration after a certain time. Therefore:
• Avoid unnecessary discussion
• Stick to the agenda
• Focus on important topics only
Short and focused meetings increase productivity.
Ideal Duration:
Easy2Siksha.com
• Small meetings: 30–45 minutes
• Detailed discussions: 60 minutes maximum
8. Use Visual Aids and Screen Sharing
Visual presentation helps people understand topics more easily.
The organizer can use:
• Slides
• Charts
• Videos
• Diagrams
• Screen sharing
Visual content makes meetings:
• More interesting
• Easier to understand
• More interactive
For example, a teacher explaining a science concept through diagrams helps students learn
faster.
9. Record Important Meetings
Recording meetings can be very useful.
Benefits include:
• Participants can review later
• Absent members can watch the meeting
• Important decisions remain documented
However, participants should be informed before recording.
10. Summarize Key Points at the End
Before ending the meeting, the organizer should summarize:
• Main discussions
• Final decisions
Easy2Siksha.com
• Assigned tasks
• Deadlines
This ensures everyone clearly understands what to do next.
Example:
• Student A will prepare presentation
• Student B will submit report by Friday
• Next meeting on Monday
A clear conclusion avoids confusion later.

7. What is a digital footprint ?. What is difference between active and passive digital
footprints? How can you protect your digital footprints ?
Ans: Imagine walking down a long, sandy beach. With every step you take, you leave a deep
footprint in the sand. If someone wanted to know where you went, how fast you were
walking, or even what kind of shoes you were wearing, all they would have to do is turn
around and follow your tracks.
When you use the internet, you are doing the exact same thing—except instead of a sandy
beach, you are walking through the digital world. This trail of data you leave behind is called
your digital footprint.
Every single time you go online to play a game, watch a video, double-tap a photo, or look
up answers for your homework, you leave a trace. But unlike footprints on a beach that
wash away with the next high tide, digital footprints are highly permanent. Once
information is out there on the internet, it is incredibly difficult—sometimes impossible—to
completely erase.
The Two Types of Footprints
To truly understand how your data is collected, you need to know that your digital trail is
split into two distinct categories: Active and Passive.
Easy2Siksha.com
1. The Active Digital Footprint (What You Share)
Your active footprint is the data you leave behind on purpose. You are making a conscious
choice to put this information out into the world. You know you are doing it, and you are
hitting the "send" or "post" button yourself.
Examples of an active footprint:
• Posting a photo or a video on social media.
• Leaving a comment on a YouTube video or an online forum.
• Filling out an online form to subscribe to a newsletter.
• Sending an email or a text message to a friend.
• Agreeing to install an app on your phone.
2. The Passive Digital Footprint (What Is Tracked)
This is where things get a little sneakier. Your passive digital footprint is the data you leave
behind without realizing it. You aren't actively hitting "post," but websites, apps, and
servers are quietly collecting information about you in the background while you browse.
Examples of a passive footprint:
• Cookies: When you visit a website, it often drops a tiny file called a "cookie" onto
your device to remember you. This is how a website knows what you left in your
shopping cart yesterday, or why you suddenly see ads for a video game right after
you searched for it on Google.
• Location Tracking: Your phone's GPS constantly pings cellular towers, telling apps
exactly what city (and sometimes what street) you are on.
• IP Addresses: Every device has a unique identifying number (an IP address).
Websites log this number to see where their visitors are coming from.
• Scroll Time: Apps like TikTok or Instagram actually measure how many seconds you
hover over a specific video to learn exactly what holds your attention.

say).
Lower (requires digging into privacy
settings).
Why Does Your Digital Footprint Matter?
You might be thinking, "So what if a website knows I like watching funny cat videos? Who
cares?"
It matters because your digital footprint builds your online reputation. In the modern world,
your digital identity is just as important as your real-life identity. When you eventually apply
for a part-time job, try to get into a college, or join a sports team, there is a very high chance
that the people in charge will search your name online.
If your footprint is full of kind interactions, creative projects, and positive hobbies, it works
like a giant digital resume that makes you look great. But if your footprint contains mean
comments, inappropriate photos, or aggressive arguments, it can cost you real-world
opportunities, even if those posts are years old.
How to Protect and Manage Your Footprint
You don't need to be afraid of the internet or stop using it entirely. You just need to be a
smart digital citizen. Here are the best ways to protect your trail:
• Think Before You Post: Once you post a picture or a comment, someone else can
screenshot it in a fraction of a second. Even if you delete it five minutes later, it
might already be saved on a stranger's phone. If you wouldn't want your
grandmother or your school principal to see it, do not post it.
• Lock the Digital Doors (Privacy Settings): Go into the settings of your social media
accounts and make sure your profiles are set to "Private." This ensures that only
people you actually know and approve can see what you share.
• Sweep the Trail (Clear Cookies and History): Make it a habit to go into your web
browser settings and clear your browsing history and "cookies" every few weeks.
This stops websites from building massive, long-term profiles on your habits.
Easy2Siksha.com
• Google Yourself: It might sound funny, but type your own name into a search engine
(use quotation marks around your name, like "John Smith") and see what comes up!
It is the easiest way to find out exactly what your public footprint looks like to a
stranger.
8. How digital distractions and excessive screen time degrade the performance of a
student ? How can these be reduced ?
Ans: How Digital Distractions and Excessive Screen Time Degrade the Performance of a
Student? How Can These Be Reduced?
In today’s modern world, digital devices like smartphones, laptops, tablets, televisions, and
gaming consoles have become an important part of students’ lives. Students use these
devices for studying, attending online classes, watching educational videos, communicating
with teachers, and completing assignments. Technology has made education easier and
faster. However, when students spend too much time on screens or become distracted by
social media, games, and entertainment, it starts affecting their studies, health, and overall
performance.
Digital distractions and excessive screen time are among the biggest problems faced by
students today. Many students intend to study for one hour but end up spending most of
their time scrolling social media, watching short videos, chatting, or playing games. This
habit slowly reduces concentration, memory, discipline, and academic performance.
Meaning of Digital Distractions
Digital distractions are interruptions caused by digital devices or online activities that divert
a student’s attention away from studies or productive work.
Some common digital distractions are:
• Social media apps like Instagram, Facebook, Snapchat, and WhatsApp
• Online gaming
• YouTube and OTT platforms
• Notifications and messages
• Endless scrolling on short-video apps
• Watching unnecessary content online
These distractions break a student’s focus and waste valuable study time.
Meaning of Excessive Screen Time
Easy2Siksha.com
Excessive screen time means spending too many hours using digital devices such as mobile
phones, computers, televisions, or tablets beyond what is necessary.
A student may use screens for:
• Online classes
• Homework
• Entertainment
• Gaming
• Social media
• Watching videos
When the total screen usage becomes very high every day, it starts harming the body and
mind.
How Digital Distractions Degrade Student Performance
1. Loss of Concentration
The biggest effect of digital distractions is reduced concentration. Students constantly check
notifications, messages, or social media while studying. Their attention shifts again and
again.
For example:
A student starts reading a chapter. Suddenly, a mobile notification appears. The student
opens Instagram “for just 2 minutes” but ends up spending 30 minutes online.
This habit weakens focus and makes studying difficult.
Simple Diagram
Study → Notification → Social Media → Time Waste → Loss of Focus
2. Poor Academic Performance
Students who spend too much time online often complete less study work. They may:
• Skip homework
• Delay assignments
• Study less before exams
• Forget important topics
As a result, their marks and overall performance decrease.
Easy2Siksha.com
When students waste time digitally, they get less time for revision and practice.
3. Weak Memory and Learning Ability
The human brain learns better when it remains calm and focused. Continuous screen use
overloads the brain with information.
Watching many videos, reels, or fast-changing content reduces deep thinking ability.
Students may find it difficult to remember what they studied because their mind becomes
restless and distracted.
4. Lack of Sleep
Many students use mobile phones late at night. Blue light from screens affects sleep quality.
Poor sleep causes:
• Tiredness
• Headaches
• Laziness
• Lack of concentration in class
A tired brain cannot perform well in studies.

5. Increased Stress and Anxiety
Social media creates comparison among students. They may compare their looks, lifestyle,
marks, or achievements with others. This can create:
• Stress
• Anxiety
• Low confidence
Easy2Siksha.com
• Fear of missing out (FOMO)
Mental stress directly affects academic performance and emotional health.
6. Reduced Reading and Writing Habits
Students who spend too much time on short videos or entertainment apps gradually lose
interest in books and long reading.
Their:
• Vocabulary becomes weak
• Writing ability decreases
• Patience for learning reduces
They become more interested in entertainment than education.
7. Physical Health Problems
Excessive screen time also harms physical health.
Common problems include:
• Eye strain
• Neck pain
• Headaches
• Obesity due to less physical activity
• Poor posture
An unhealthy body affects a student’s energy and study performance.
8. Time Mismanagement
Digital distractions waste a huge amount of time. Students often think they are using the
phone for a few minutes, but hours pass unknowingly.
This creates:
• Incomplete work
• Last-minute exam preparation
• Panic and pressure
Easy2Siksha.com
Good time management becomes difficult.
How Can Digital Distractions and Excessive Screen Time Be Reduced?
Reducing digital distractions requires discipline, planning, and self-control. Students must
learn to use technology wisely.
1. Make a Proper Study Schedule
Students should prepare a daily timetable with fixed study hours and limited entertainment
time.
A balanced schedule helps students:
• Stay organized
• Avoid unnecessary screen use
• Complete work on time
2. Turn Off Unnecessary Notifications
Notifications are one of the biggest causes of distraction.
Students should:
• Mute social media apps while studying
• Use “Do Not Disturb” mode
• Keep the phone away during study hours
This improves concentration greatly.
3. Set Screen Time Limits
Students should decide how many hours they can spend on entertainment daily.
For example:
• 1 hour social media
• Limited gaming time
• No mobile during study sessions
Many phones now provide screen-time tracking features.
Easy2Siksha.com
4. Follow the 20-20-20 Rule
To protect eyes from screen strain:
Every 20 minutes,
look at something 20 feet away
for 20 seconds.
This reduces eye stress and improves comfort.
5. Take Regular Breaks
Continuous screen use tires the brain. Students should take short breaks between study
sessions.
Healthy activities during breaks:
• Walking
• Stretching
• Drinking water
• Talking with family
• Going outside
These activities refresh the mind.
6. Develop Offline Hobbies
Students should spend time on:
• Sports
• Reading books
• Drawing
• Music
• Exercise
• Outdoor games
Offline hobbies reduce dependence on digital devices.
7. Avoid Mobile Use Before Sleep
Easy2Siksha.com
Students should stop using screens at least 1 hour before bedtime.
Instead, they can:
• Read a book
• Listen to calm music
• Prepare for the next day
This improves sleep quality.
8. Use Technology for Learning, Not Only Entertainment
Technology itself is not bad. The problem is misuse.
Students should use digital devices for:
• Online learning
• Educational videos
• Research
• Skill development
• Language learning
When used properly, technology becomes a powerful educational tool.
Conclusion
Digital technology has become an important part of modern education, but excessive screen
time and digital distractions can seriously harm a student’s academic performance, health,
concentration, and mental well-being. Social media, games, and constant notifications
reduce focus and waste valuable study time.
Students must learn to maintain balance in life. By controlling screen time, following
discipline, managing time properly, and focusing more on healthy activities, students can
improve their concentration, health, and academic success.
Technology should be used as a tool for growth and learning, not as a source of addiction
and distraction. A wise student knows how to control technology instead of being controlled
by it.
