The following diagram shows how a user connects to the internet. It is made up of many different networks, in different countries around the world that are all connected together into one huge WAN. The internet is a global network of networks. The internet is a computer network that consists of billions of connected devices, allowing people to share information, obtain entertainment, or chat to one another. It allows wireless devices to connect to each other in a local network, but does not connect the local network to the internet. A WAP is like a hub for wireless devices.
If you do not need internet access, you could also use a wireless access point (WAP). The router can connect all your devices to the internet. Most notebooks and smartphones have built-in wireless network adapters, while most desktop computers do not.Īs with a wired network, you can use a router with wireless capabilities to connect all your devices in the same network. Much like a network adapter, a wireless network adapter is a device that you can purchase and connect to your computer to access wireless networks. That is almost three internet-connected devices per person! By the year 2020, this number is expected to increase to 50 billion devices. In 2018, there were more than 23 billion devices connected to the internet. They can also be used to connect two networks to each other. Hubs, switches or routers: These are devices that allow multiple computers to connect to the same network. If you are connecting directly to the internet, you may require a specific cable for the type of internet connection you are using, for example a DSL-enabled phone cable, or a fibre-optic cable.ģ. Network cables: These cables are used to connect a computer to a LAN, or to connect one network to another network. These days, most computers and laptops have a network adapter built into their motherboards.Ģ. A network adapter: This is a piece of hardware that can be added to a computer and makes it possible to connect to a network. To create a wired network, you need the following three types of networking equipment:ġ. The following table shows some of the advantages and disadvantages of a WAN. Unlike LANs, many WANs are not private instead, they are organised by communities or businesses. This can be done through the use of satellites or telecommunication networks. A typical use of WANs in business is where different branches of a business are connected to share resources. These uses include the following:Ī wide-area network (WAN) is a network that covers a large geographical area, such as a neighbourhood, a city, a country, or even the world.Ī WAN connects two or more LANs. Networks are incredibly powerful tools that are used on a daily basis by businesses and private users. The network is usually limited to a certain number of computers (between two and 25), but there is no absolute limit. In Grade 10, you learned about home and personal area networks, and in Grade 11, you learned that a local area network (LAN) is a computer network that covers a small area, such as a house or office, and that the computers in the network share resources, such as internet connections, printers and server connections.

In previous years, you learned that a network is a series of independent computers that have been connected with either a physical, or a wireless connection. Figure 4.1: A breakdown of internet usage every day UNIT 4.1 Networks Finally, we will explain broadband and bandwidth, and how they are affected by throttling and shaping.

We will discuss how to obtain an internet connection and give some examples of internet services. In this chapter, we will look at a wide-area network (WAN), as well as the best-known wide-area network, the internet. But how exactly does it work? In order to answer this question, we will be taking a look at the basis of the internet – i.e. It has brought us a wealth of information, it has enabled us to conduct business from our homes, it connects millions of people and it provides an endless source of entertainment. The internet is one of the largest, most powerful and entertaining inventions ever made by humans.
