Chapter 8 — Internet – Online Surfing

What is the Internet? The Internet is a very large set of networks joined together to let computers and devices share information. Think of it like a huge system of roads: instead of cars, these roads carry messages, pictures and files between different places. The Internet connects schools, homes, shops, libraries and many other computers so people can talk, learn and work together across distance.

The Internet works because of many rules and services. A device such as a laptop or tablet connects to the Internet through a network, often using a modem, router or Wi-Fi. When you ask for a web page, your device sends a request to another computer called a server. The server finds the page you asked for and sends it back so your browser can show it. Many types of services run on the Internet: websites for reading content, email for sending messages, video services for watching lessons, and online stores for buying goods.

Using the Internet must be done with care. Some information is true and helpful, while some can be wrong or unsafe. It is important to know that the Internet is not one single place but many machines and people working together. Learning how it connects and where information comes from helps you use it better for schoolwork, to ask questions, and to communicate with friends and family.

Finally, the Internet changes how we learn and play. It gives access to many resources like pictures, stories, and educational games, but it also brings new responsibilities: protecting personal information, following rules, and asking adults for help when unsure. Understanding the Internet helps you be a smart and safe user.

Web browser and its parts A web browser is the software you open when you want to view web pages on the Internet. Common examples are Chrome, Firefox and Edge. The browser turns the information sent by web servers into pages with text, images, videos and links that you can read and interact with. Knowing the parts of the browser helps you move around the web safely and efficiently.

The main parts of a browser include the address bar, where you type a website's address (URL) or search terms; the tab area, where each open webpage appears as a separate tab so you can switch quickly between pages; and navigation buttons such as Back, Forward and Refresh. The Back button returns you to the previous page, Forward moves you forward again, and Refresh reloads the page to show updated content. There is also a bookmarks or favourites feature that lets you save addresses you visit often so you can open them quickly later.

Browsers also include menus and settings. In the settings you can clear browsing history, manage saved passwords, set privacy options, and control site permissions like the ability to use your camera or microphone. Many browsers show the security status of a website using a padlock icon near the address bar; this helps you know if the connection is secure. You may also find a Downloads area that lists files you have saved from the web.

Using the browser well means opening only trusted sites, closing tabs you do not need, and keeping browser updates installed. Teachers and parents can help set safe settings for young users. Learning these parts allows you to find information faster, stay organised, and remain secure while surfing the web.

Website and webpage A website is a group of web pages about one topic, organisation or person. Each webpage is like a page in a book: it contains content such as headings, paragraphs, images, videos and links. A website may have many pages: for a school website these could be 'Home', 'About Us', 'Homework', 'Gallery' and 'Contact'. When you visit a website, the homepage usually opens first and acts like the cover of a book.

Webpages use a layout to present information clearly. They often include a navigation menu or a list of links that help you move to different sections. A web address (URL) points to a specific page. For example, www.schoolname.edu/home could be the homepage while www.schoolname.edu/homework might open the homework page. Websites are stored on servers that send the page to your browser when you request it.

Websites can serve many purposes. Some are made for learning and have lesson notes and worksheets; some provide news, games, or places to shop. The design and language of a website give clues about its purpose. Educational websites usually show clear sources, teacher or institution names and are updated regularly. Some websites allow interactions like filling forms, submitting answers, or chatting; these are called interactive sites.

When using websites for schoolwork, check the address, author and date to ensure reliability. Avoid entering personal information into sites you do not trust. By understanding the difference between a website (the whole place) and a webpage (one page inside it), you can better find and use information online for learning and projects.

Using search engines A search engine is a tool that helps you find pages on the Internet by typing words related to what you want. Popular search engines accept simple words or questions and return a list of results. Each result usually includes a title, a short description and the web address. Learning how to give good search instructions will save time and give more useful results.

Start with clear keywords. For instance, type 'water cycle for class 6' when you need a simple explanation. Use fewer words but include the most important ones: subjects, class number, and format such as 'diagram' or 'video'. If results are too many or not useful, add another word like 'worksheet' or 'short summary'. If you want exact words together, you can use quotation marks around the phrase. Use filters on the search page to limit results to images, videos, or news if needed.

Always read the short descriptions shown beneath each result to check if a page will be helpful before you click. Be careful with the first result because it may be an advertisement; ads are often marked as such. Check the website address and look for trustworthy domains like those belonging to schools, government, or recognised educational organisations. If you find conflicting information, open more than one source to compare facts.

Search engines can also suggest related searches or let you search by image. Use the search history to return to earlier results, and ask a teacher if you cannot find good information. Practising smart search habits helps you find accurate material for homework and projects more quickly, and makes you a better learner online.

Links and navigation Links or hyperlinks are parts of a webpage that you click to go to another page, another website, or to open a file. Links may look like coloured or underlined text, buttons, or images. Navigation is how you move through pages on a site using menus, links and buttons. Good navigation helps you find what you want quickly without getting lost.

When you place the pointer over a link (hover) most browsers show the destination address at the bottom; this helps you check where it will take you before clicking. Links can open in the same tab or a new tab. Opening in a new tab keeps your current page available if you want to return. On tablets and phones, a long press may show options like "Open in new tab".

Some links start downloads, open documents, or play videos. Be careful with links in emails or messages from people you do not know—these may lead to unsafe websites that try to steal information or install harmful software. Always check the web address and if a site looks strange, close it and ask an adult. Use the browser's Back button to return to the previous page if a link is not helpful, and use bookmarks to save important pages you may need again.

Good navigation skills include recognising menus, using search boxes on websites, and knowing when to use the browser's history to find a page you visited earlier. Learning to follow links safely makes web browsing faster and helps you find reliable information for your schoolwork.

Email basics Email is an electronic message sent using the Internet. It is used for communicating with teachers, classmates and family. An email typically has fields called To (where you write the recipient's email address), Subject (a short summary), and the message body where you type the content. You can also attach files such as documents, pictures or PDFs to send schoolwork or reports.

When you write an email, begin with a polite greeting such as 'Dear Sir' or 'Hello Ma’am', include a clear subject line like 'Homework Submission', write the message in a few clear sentences, and end with your name and class. Keep messages short and to the point. Before sending an email with an attachment, check that you have attached the correct file and that the file size is within limits. Learn to use reply, reply all and forward carefully: reply goes to the sender, reply all sends to all recipients, and forward shares the message with new people.

Never share your email password with friends. If you use a shared computer, always log out after checking your email. Be careful with emails from unknown senders; do not click links or open attachments from such emails as they may be harmful. If you receive an email that feels strange, ask a teacher or parent before acting on it. Teachers often use email to send notices or accept homework, so learning to write polite and clear emails is an important skill for school life.

Also learn to organise your inbox by creating folders for school, personal and other messages. This makes it easier to find important messages later. Practising these simple email habits keeps your communication clear and safe.

Media on the web Webpages can include different types of media such as images, videos and audio. These media help explain ideas more clearly than text alone. An image can show diagrams or maps; a video can demonstrate a science experiment step-by-step; audio can provide spoken stories or language practice. Media can be embedded in a webpage or linked from another site.

When you use media for learning, choose clear and relevant examples. For school projects, images of maps, charts or labelled diagrams are useful. Videos with educational content often include captions and can be paused or replayed to study difficult parts. Audio clips are helpful for listening practice and for learning poems or songs. Many educational sites offer media that is designed for classroom use.

Pay attention to copyright and permissions. Not all pictures or videos may be reused freely. Use media labelled for reuse or ask your teacher or parent for permission. Streaming videos need a stable internet connection; if the connection is slow, reduce the video quality or download the file from a trusted source with permission. Also watch out for autoplaying videos that may have unsuitable ads or loud sounds; browser settings or extensions can block autoplay.

Some media files can be large, so check file size before downloading. Avoid clicking on unfamiliar media links that may lead to unsafe sites. Always preview content first, and if something looks wrong, close it and tell an adult. Using images, video and audio thoughtfully makes learning richer while keeping you safe online.

Downloading and uploading Downloading means saving a file from the Internet to your device; uploading means sending a file from your device to a website, email or cloud service. You will download worksheets, images or videos for class and upload completed assignments or pictures for projects. Knowing how to do these safely and where files are stored will help you keep your schoolwork organised.

When downloading, choose trusted websites such as your school portal or known educational sites. Check the file type: common safe file types for school work are .pdf, .docx, .jpg and .png. Avoid running files with extensions like .exe on school computers. Always look at the download location in your browser settings so you know where the file will be saved. Rename the file if needed and move it to a folder such as 'SchoolWork' so you can find it later.

When uploading assignments, make sure the file is in the required format and within any size limits set by the teacher or website. Use clear file names, for example 'Math_Homework_Rahul_Class6.pdf', so the teacher can identify your work easily. If the upload fails, check your internet connection and try again, or ask a teacher for help. Be careful with public computers: delete downloaded files when you finish and log out of accounts so others cannot access your data.

Security steps include scanning downloaded files with antivirus software where available, not opening attachments from unknown senders, and asking an adult before downloading unfamiliar software. Practising safe download and upload habits protects your device and personal information while helping you manage schoolwork efficiently.

Privacy and personal information Personal information is any detail that identifies you or your family, such as full name, home address, telephone number, date of birth, school name and passwords. Protecting this information online keeps you safe from strangers who might misuse it. Always think before sharing any personal detail on websites, games or chat rooms that are open to the public.

When filling forms online, provide only the required information. If a website allows a nickname instead of your full name, use the nickname. Avoid sharing home address or phone number in public posts or comments. For photos, ask permission from others before posting images that show classmates or friends. Many websites have privacy settings—use them to control who can see your posts and profile details. Parents and teachers can help set strong privacy settings for younger users.

Another important part of privacy is keeping passwords secret. Do not share passwords with friends, and do not write them where others can find them. Use different passwords for different accounts when possible. If a website asks for more information than seems necessary, stop and ask an adult. If someone online asks to meet in person or requests personal details, tell a trusted adult immediately. These steps help prevent identity theft and other harms.

If you suspect your information has been shared or used without permission, tell your parents or teacher right away. Keeping personal information private protects you and helps you enjoy the Internet safely for learning and fun.

Creating strong passwords A password is the first line of defence for your online accounts. A strong password is long, not easy to guess, and uses a mix of upper and lower case letters, numbers and special symbols. It should not be a common word like 'password' or a personal detail such as your name or birthday that others can guess.

To create a memorable but strong password, use a short phrase you can remember and take the first letters of each word. Add numbers and a symbol to make it harder to guess. For example, 'I love reading comics at night' can become 'Ilrc@n1'. Another method is to use a mix of unrelated words with numbers between them. Avoid using the same password for all accounts; if one account is compromised, others remain safe. If remembering many passwords is hard, keep them written on paper in a safe place at home until you memorise them, rather than sharing them online or with friends.

Also use two-step verification when available. This asks for an extra code sent to your phone or email when you log in, making access much safer. Change passwords regularly and change them immediately if you think someone else knows them. For shared devices, do not save passwords in the browser; always log out after using an account. Teaching these good password habits early will protect your school email, online homework and personal information as you use the Internet more.

Recognising reliable websites When you do schoolwork online, it is important to use information from trustworthy websites. Reliable websites are usually made by schools, universities, government departments or well-known publishers and organisations. They clearly show the author, date of publication and references or sources. They rarely contain many spelling mistakes or strange claims without proof.

To check a website's reliability, first look at the web address and domain. Sites belonging to educational institutions or governments often have endings like .edu, .gov or official state domains. Next, look for an author name and a date on the page; recent dates and named authors are better. Read the 'About' or 'Contact' page to know who runs the site. Check whether the page lists sources or further reading. Reliable sites usually link to other trusted sources and provide evidence for facts.

Avoid sites that show many pop-up advertisements, aggressive headlines or sensational claims that seem too good to be true. Cross-check facts by visiting more than one trustworthy site. For images and diagrams, see if the site lists where they came from or if they are labelled for reuse. If you are unsure, ask a teacher to confirm that a website is suitable for your assignment. Learning to judge websites will make your homework accurate and save time by steering you to good information quickly.

Finally, remember that even trusted sites can have mistakes. Use several sources and develop the habit of checking facts before copying them into your work.

Online safety rules and cyberbullying Being safe online means following clear rules and knowing what to do if someone tries to hurt you using messages or posts. Basic safety rules include: do not share personal information, do not click unknown links, use strong passwords and always ask an adult before downloading files or meeting someone you met online. These rules help protect your privacy and keep your devices free from harmful software.

Cyberbullying is when someone uses the internet, social media or messages to hurt, threaten or embarrass another person. It can be through mean messages, sharing private photos without permission, or spreading rumours. Cyberbullying can make a student feel sad, scared or alone. If you face cyberbullying, do not reply or try to argue online. Save the messages or take screenshots as evidence, block the person who is bullying you, and tell a trusted adult such as a parent or teacher. Most websites and apps have ways to report abusive behaviour—use those features with the help of an adult.

Being a good online citizen also means treating others with respect: think before you post, do not share someone else’s private photo without permission, and do not forward hurtful messages. Help classmates by encouraging them to tell an adult if they face trouble. Schools often have rules about acceptable online behaviour and consequences for bullying. Learn these rules and follow them. If you are unsure how to react, ask a teacher. Speaking up early helps stop cyberbullying and creates a kinder online space for everyone.

Responsible use and digital footprint Everything you post, share or send online can leave a trace that may last for a long time. This trail is called your digital footprint. It includes social media posts, comments, images you upload, messages and anything stored in online accounts. Even if you delete a post, copies might remain if others have saved or shared it. Your digital footprint can affect your reputation in school and later in life when colleges or employers look up your online record.

Responsible use means thinking before you post: ask yourself whether what you share is polite, true and something you would not mind many people seeing. Avoid sharing embarrassing pictures of others or repeating rumours. When working on group projects, get permission before posting photos that include classmates. Use clear, respectful language in emails and online posts because written words can be read by many and may be misinterpreted.

Manage your accounts carefully. Keep profiles private when possible, use strong passwords and review privacy settings to limit who can see your posts. Keep schoolwork files organised in folders and share links only with those who need access. Learn to remove or correct mistakes and ask a trusted adult for help if something goes wrong. Be aware that positive online behaviour—helpful posts, respectful comments and good schoolwork—creates a good digital footprint that reflects well on you.

Teaching responsible use now helps you build a safe and positive presence online as you grow. It is a key part of being a thoughtful digital citizen and will benefit you throughout school and beyond.
