IV. NETWORKS
Task 1. Read the text “What is a network?” and answer to the questions.
A network is how one can link two or more computers together to share resources, files, or even an internet connection. Most homes and workplaces have networks set up to connect their computers somehow, but four key types of networks are available to users. 
What Is the Definition of a Network?
A network can have a pretty broad definition. At its simplest, it always involves two or more computers being linked either physically with cables or via a Wi-Fi connection. By being linked, these computers can share their resources, files, or internet connection without manually connecting on each occasion. 
Where networks can get much more complex is when it comes to size. A family home might, for instance, have a network consisting of two home computers and a Wi-Fi connection (which the family uses for various additional devices such as a smart TV, streaming box, smartphones, etc.). However, an office building may have an extensive network with thousands of computers connected to it physically with Ethernet cables. Some networks can even expand to cover large geographic areas. 
There are also four main types of networks, and it's essential to know the difference between them.
