INTERNET TECHNOLOGIES: HTTPS, ISP, INTERNET SERVICES, SEARCH ENGINES & BROWSERS
INTRODUCTION
Think about the last time you searched for something online — maybe you Googled a topic for an assignment, watched a video on YouTube, or chatted with a friend on WhatsApp. Have you ever stopped to wonder how all of that actually works? How does your phone in Lagos connect to a website hosted thousands of kilometres away in the United States — in just a few seconds?
The answer lies in Internet Technologies.
In today's world, the internet is no longer a luxury. It is woven into everyday life — from how Nigerian banks operate, to how students access learning materials, to how market traders advertise their goods on social media. Understanding the technology behind the internet is not just a school requirement; it is a life skill.
This lesson will walk you through the key internet technologies you need to know as an SSS 1 student: HTTPS, ISPs, Internet Services, Search Engines, and Web Browsers. By the time you finish reading, you will not only understand these concepts — you will be able to explain them to someone else.
LEARNING OBJECTIVES
By the end of this lesson, students should be able to:
- Define internet technologies and explain how the internet works in simple terms.
- Identify the role of an Internet Service Provider (ISP) in connecting users to the internet.
- Explain the meaning and importance of HTTPS in safe internet browsing.
- Describe different types of internet services and give examples relevant to Nigerian users.
- Distinguish between a search engine and a web browser, and explain how each is used.
- Demonstrate responsible and safe use of the internet in everyday activities.
SECTION 1: WHAT IS THE INTERNET?
Before we talk about internet technologies, let us make sure we understand what the internet actually is.
The internet is a massive global network that connects millions of computers, smartphones, tablets, and other devices around the world. It allows people to share information, communicate, and access services from anywhere.
Think of the internet like the road network in Nigeria. Just as roads connect cities like Lagos, Abuja, Kano, and Port Harcourt, the internet connects devices across the world. And just like you need a vehicle to use the road, you need certain technologies to access and use the internet.
SECTION 2: INTERNET SERVICE PROVIDERS (ISP)
What Is an ISP?
An Internet Service Provider, commonly called an ISP, is a company that provides you with access to the internet. Without an ISP, your device cannot connect to the internet — no matter how good it is.
How Does an ISP Work?
When you subscribe to an internet plan, your ISP assigns your device a unique address called an IP address (Internet Protocol address). This address is like your home address — it tells the internet where to send the information you request.
Your ISP then acts as the "gateway" between your device and the rest of the internet.
Examples of ISPs in Nigeria
Nigerian students and families are very familiar with these names:
- MTN Nigeria — one of the largest mobile internet providers in the country
- Airtel Nigeria — widely used for data subscriptions
- Glo (Globacom) — known for affordable data bundles
- 9mobile — another popular mobile network provider
- Spectranet — provides home broadband internet
- Smile Communications — offers 4G LTE internet services
Types of Internet Connections ISPs Offer
Mobile Data (3G, 4G, 5G): This is the most common in Nigeria. You buy data on your phone and browse through mobile networks.
Broadband/Fibre: Faster and more stable. Used in offices and some homes. Companies like ipNX and Spectranet offer this.
Wi-Fi Hotspots: Public internet access points found in cafes, schools, and airports.
Satellite Internet: Available in remote areas where cables cannot reach. Starlink has recently become available in Nigeria.
SECTION 3: UNDERSTANDING HTTPS
What Does HTTPS Mean?
HTTPS stands for HyperText Transfer Protocol Secure. It is the system that controls how data is transferred between your browser and a website.
Let us break it down:
- HyperText Transfer Protocol (HTTP) — This is the basic set of rules for sending and receiving web pages on the internet.
- The "S" in HTTPS stands for Secure — meaning the connection is encrypted and protected.
Why Is HTTPS Important?
When you visit a website using HTTPS, all the information you send or receive is scrambled (encrypted) so that no one else can read it. This is very important when you are:
- Logging into your school portal
- Using internet banking (like GTBank or Access Bank online)
- Shopping online (like Jumia or Konga)
- Entering personal details on any website
How to Know If a Website Is Using HTTPS
Look at the web address (URL) at the top of your browser. A secure website will begin with https:// and you will usually see a small padlock icon beside it.
If a website shows http:// without the "S", be careful — your information may not be protected.
Real Nigerian Example: When you visit www.jumia.com.ng to buy something, notice that the address starts with https://. This tells you the site is secure and your payment details are protected.
HTTP vs HTTPS — Quick Comparison
HTTP:
- Not encrypted
- Less secure
- Suitable for reading general content only
HTTPS:
- Encrypted and secure
- Protects personal data
- Required for online transactions
SECTION 4: INTERNET SERVICES
The internet is not just for browsing websites. It offers a wide range of services that people use every day. Here are the major categories:
- World Wide Web (WWW)
This is the most well-known internet service. The web is a collection of billions of pages (websites) that contain text, images, videos, and links. You access it using a web browser.
Example: Visiting www.bbc.com to read news, or www.nairaland.com to join discussions.
- Electronic Mail (E-mail)
Email allows you to send and receive messages electronically. It is used for formal communication in schools, businesses, and government offices.
Examples of email services: Gmail, Yahoo Mail, Outlook
Nigerian context: JAMB sends important notifications to candidates through email. Many universities also communicate with students via email.
- Social Media
Platforms that allow people to connect, share, and communicate online.
Examples: Facebook, Instagram, Twitter/X, TikTok, WhatsApp
These platforms are extremely popular among Nigerian youth for entertainment, news, and business.
- Streaming Services
Allow users to watch videos or listen to music online without downloading them.
Examples: YouTube, Netflix, Spotify, Audiomack
Many Nigerian musicians now release their songs on these platforms.
- Online Banking and Financial Services
Banks like GTBank, First Bank, and Zenith Bank offer internet banking services that allow customers to transfer money, pay bills, and check balances online. Mobile payment apps like OPay, PalmPay, and Flutterwave are also internet-based services.
- E-Learning Platforms
These allow students to take classes online.
Examples: ULesson, Coursera, Khan Academy, Google Classroom
Many Nigerian schools used e-learning platforms during the COVID-19 pandemic to continue teaching.
- Cloud Storage
Allows you to store files online and access them from any device.
Examples: Google Drive, Dropbox, iCloud
- Video Conferencing
Allows people to hold meetings and classes over the internet.
Examples: Zoom, Google Meet, Microsoft Teams
These became very important in Nigeria during the pandemic.
SECTION 5: WEB BROWSERS
What Is a Web Browser?
A web browser is a software application that allows you to access and view websites on the internet. Think of it as the "vehicle" you use to travel the roads of the internet.
When you type a website address into a browser, it sends a request to the web server, receives the page, and displays it on your screen.
Popular Web Browsers
Google Chrome: The most widely used browser in the world. Very fast and supports many extensions.
Mozilla Firefox: Known for strong privacy features.
Microsoft Edge: Built into Windows computers. Improved significantly in recent years.
Safari: The default browser on Apple devices (iPhones and MacBooks).
Opera Mini: Extremely popular in Nigeria because it compresses data, making browsing cheaper and faster on slow networks.
Brave: A newer browser focused on privacy and blocking ads.
Parts of a Web Browser
Address Bar: Where you type the website address (URL) Tabs: Allow you to open multiple websites at once Back and Forward Buttons: Navigate between pages you have visited Bookmarks: Save your favourite websites for easy access Refresh Button: Reload the current page Home Button: Takes you to your default homepage
Browser vs Search Engine — Know the Difference
This is one of the most common points of confusion for students, so pay close attention.
A browser is the software you use to access the internet (e.g., Chrome, Firefox).
A search engine is a website or tool inside the browser that helps you find information (e.g., Google, Bing).
Simple way to remember it: Your browser is like a TV set. Your search engine is like the remote control that helps you find the channel you want.
SECTION 6: SEARCH ENGINES
What Is a Search Engine?
A search engine is an online tool that helps you find information on the internet by searching through billions of web pages. You type in a keyword or question, and the search engine returns a list of relevant websites.
How Do Search Engines Work?
Search engines use programs called "web crawlers" or "spiders" to constantly scan websites across the internet. They store this information in a huge database called an index. When you search for something, the engine looks through its index and ranks the most relevant results for you.
Popular Search Engines
Google: The most popular search engine in the world. Used by the vast majority of Nigerians.
Bing: Developed by Microsoft. Second most popular globally.
Yahoo Search: Older search engine still used by many people.
DuckDuckGo: Focuses on user privacy — does not track your searches.
Yandex: Popular in Russia but accessible worldwide.
Tips for Effective Searching in Nigeria
Use specific keywords: Instead of typing "how to pass exam", type "how to pass WAEC Mathematics".
Use quotation marks: Put phrases in quotes to search for exact words. Example: "JAMB 2025 registration"
Use Google Scholar for academic research: It shows educational articles and journals.
Filter results by date: Very useful when searching for recent news.
PRACTICAL APPLICATIONS IN NIGERIA
Here is how these internet technologies affect everyday Nigerian life:
Students use search engines like Google to research topics for school assignments and projects.
Parents use ISPs like MTN to subscribe to data plans for their children to study online.
Traders and entrepreneurs use HTTPS-secured platforms like Jumia and Konga to sell their products safely.
Job seekers use browsers like Chrome to visit recruitment websites and apply for jobs.
NYSC members use online portals (HTTPS-secured) to register and check their postings.
Churches and mosques stream services on YouTube using internet services.

SAFETY AND ETHICAL CONSIDERATIONS
Being online comes with responsibility. Here are important safety rules every SSS 1 student should follow:
Always check for HTTPS before entering personal information on any website.
Never share your password with anyone — not even your best friend.
Do not click on suspicious links in emails or text messages. These are often phishing scams designed to steal your information.
Avoid downloading files from unknown websites — they may contain viruses.
Report cyberbullying. If someone is harassing you online, tell a trusted adult.
Respect others online. Do not post hurtful comments or share people's private images without permission.
Use the internet for learning and growth, not just entertainment.
CLASSROOM AND HOME ACTIVITIES
Activity 1 — Browser Exploration Open any web browser on your phone or school computer. Identify the address bar, tabs, bookmarks, and refresh button. Write down what each part does in your exercise book.
Activity 2 — HTTPS Check Visit five different websites you know. Check whether each one uses HTTP or HTTPS. Make a table showing the website name and whether it is secure or not.
Activity 3 — Search Engine Practice Using Google, search for "benefits of coding for Nigerian students". Write down three things you learned from the first two results.
Activity 4 — ISP Research Ask a parent, guardian, or neighbour which ISP they use for internet access. Find out the name of their data plan, the cost, and how many gigabytes it includes. Share your findings with the class.

FREQUENTLY ASKED QUESTIONS (FAQ)
Q1: What is the difference between the internet and the World Wide Web? A: The internet is the global network of connected devices. The World Wide Web (WWW) is just one of the services that runs on the internet — it is the collection of websites you visit using a browser. Think of the internet as the entire road network and the web as one of the routes on it.
Q2: Which browser is best for Nigerian students? A: Opera Mini is very popular in Nigeria because it saves data by compressing web pages, which makes it ideal for students on limited data plans. Google Chrome is great if you have a good data plan, as it is fast and supports many useful features.
Q3: How can I tell if a website is safe to use? A: Check the web address. If it starts with https:// and shows a padlock icon, the website is secure. Avoid entering personal or financial information on websites that only show http://.
Q4: What is an IP address and why does it matter? A: An IP address is a unique number assigned to your device by your ISP when you connect to the internet. It works like your home address — it tells the internet where to send the information you request. Without it, websites would not know where to send the pages you are looking for.
Q5: Can I access the internet without an ISP? A: In most cases, no. You need an ISP to connect to the internet. However, you can share someone else's connection through Wi-Fi or a hotspot, but there is still an ISP involved at the source of that connection.
Q6: Is Google a browser or a search engine? A: Google is primarily a search engine — it helps you find information on the internet. However, Google also makes a web browser called Google Chrome. Many people confuse the two because Chrome's default search engine is Google.
