Computer Networks part 1

  • Course level: Beginner


Computer networks are a growing trend. You can find them at your home, school, work, and most of the places you go daily.

Learn the basic concepts of computer networks, which hardware to use to set them up, and how to secure them.

  • Become aware of networks surrounding you

When you start noticing networks around you, you will also understand a big part of the IT world. You will learn how the Internet works, how your Internet Service Provider (ISP) allows you to connect online, how do people share data without Internet access, and much more. Everything starts by becoming aware of computer networks.

  • Learn how to set up a network

Whether you are taking this course to improve yourself, to get a better grade at school, or because of work, setting up a network is a skill that is very useful today. Yet many people do not know how to do it. You have an opportunity to learn it in few minutes.

  • Learn how to protect yourself in a network, including the Internet

Unwanted sharing of passwords, pictures, documents, credit card numbers, and internet activity is not something anybody would want to share. But, with the expanded usage of computer networks, privacy is becoming an abstract term. This course helps you protect yourself when going online, and also protects your home/office network.


In this course you will learn network concepts, what are they and how do they work.

You will learn about network types, topologies, addresses, architectures, and communication modes.

In addition, you will learn about network hardware like modems, routers, and switches; and about transmission media like cables and electromagnetic waves.

The course also covers securing a network and securing yourself in a network.

It does not take a lot of time to take and view the course, but the knowledge you get will benefit your personal, and also your business life.

Who this course is for:

  1. The course is for everyone interested in learning about computer networks.
  2. Students that need help with network subjects.
  3. People who simply want to improve their knowledge about computer networks.
  4. Anyone who tried to learn about a computer network, but failed due to the lack of a perceivable image of it.
  5. People preparing for certification exams (such as CCNA).

What Will I Learn?

  • Recognize the computer network implementation on various levels and explain how does it work;
  • Understand the network concept and the need for networks;
  • Set up a LAN;
  • Recognize networking devices and implement them in a computer network;
  • Differentiate network topologies;
  • Differentiate network architectures;
  • Tell the difference between communication modes;
  • Explain the basics of the OSI (7-layer) model;
  • Differentiate MAC addresses from IP addresses;
