    Welcome. This course will take you from the basic idea of a computer network, through the Internet and the World Wide Web, to using search engines effectively and composing your own e-mail with an attachment. It is designed so you can study independently, at your own pace, without needing to attend a physical classroom. Everything you need notes, videos, activities, and assessments is provided within each unit.

    How This Course Is Organised
    The course is divided into four units, each covering one major topic from the original Unit 8 syllabus:

    Topic 1: Computer Network Concepts 

    Topic 2: Internet Concepts and History of the Internet 

    Topic 3: Search Engines 

    Topic 4: Electronic Mail

    By the end of this course, learners will be able to: 
    1. Explain the fundamental concepts, characteristics, and classifications of computer networks according to geographical coverage.
    2. Analyze Internet concepts, including URLs, web browsers, search engines, Internet services, and methods of Internet connectivity.

    Introduction
    Almost everything we do with technology today — sharing files, printing from a phone, browsing the Internet — depends on devices being connected to one another. This unit introduces the idea of a computer network: what it is, what it needs to function, why it is useful, what it costs us, and how networks are classified by the geographical area they cover. By the end of this unit, you will be able to look at any group of connected devices — in your home, your school, or a cybercafé — and describe what kind of network it is and why.


    Learning Outcomes


    By the end of this unit, you should be able to:
    1.    Define a computer network and explain what is required for one to exist.
    2.    Describe the key characteristics of a computer network.
    3.    Explain at least three advantages and two disadvantages of computer networks.
    4.    Distinguish between PAN, LAN, MAN and WAN, giving a real-world example of each.
    5.    Identify and classify the type of network operating in your own home, school, or community.

    Introduction


    If Unit 1 was about how devices connect to each other, this unit is about the largest network of all: the Internet, a worldwide network of networks that touches nearly every part of daily life in Rwanda and beyond — from checking exam results online to running a business, staying in touch with family, or consulting a doctor remotely. This unit explains the key vocabulary you need to talk about the Internet confidently, shows you how to read a web address, and tells the story of how the Internet came to exist and grow into what it is today.
    Learning Outcomes


    By the end of this unit, you should be able to:
    1.    Define the Internet, the World Wide Web, a webpage, a website, a web browser, a URL, and an ISP.
    2.    Identify the three parts of a URL and explain what each part tells you.
    3.    Describe at least three ways the Internet is used in daily life, with a Rwandan example for each.
    4.    Explain the main methods of connecting to the Internet (dial-up, broadband, Wi-Fi).
    5.    Give a brief, accurate account of how the Internet developed historically.

    Introduction


    With so much information available on the World Wide Web, finding exactly what you need would be nearly impossible without search engines. This unit explains what search engines are, weighs up their benefits and drawbacks, and perhaps most usefully teaches you how to read and interpret every part of a search results page, so you can search more efficiently and evaluate what you find more critically.
    Learning Outcomes

    By the end of this unit, you should be able to:

    1. Define a search engine and name several examples.
    2. Explain at least three advantages and two disadvantages of using search engines.
    3. Describe the procedure for deciphering (interpreting) a search results page.
    4. Identify the different sections of a typical search results page, such as sponsored links, organic results, pagination, and disambiguation.

    Introduction


    This final unit brings together everything you've learned so far networks, the Internet, and search engines into one of the most widely used Internet services: electronic mail (e-mail). You will learn how an e-mail address is structured, how to create an account, how to compose and send a message correctly (including the important difference between Cc and Bcc), how to attach and download files, and how to keep your account secure with a strong password.


    Learning Outcomes

    By the end of this unit, you should be able to:


    1. Define e-mail and explain the format of an e-mail address.
    2. State advantages and disadvantages of using e-mail.
    3. Describe how to create an e-mail account and choose a strong password.
    4. Compose, format and send an e-mail, including an attachment.
