Servers

Before one computer can communicate with another, the system requires a server.

A server is a very large computer connected to the internet. It provides services or resources to other computers. You do not need to own a server because your internet service provider will have its own server, or server cluster, that communicates with other servers to fetch the information you require.

A server may operate like your own computer, but it is more powerful with high-speed network connections, extremely fast hard disks and multiple processors.

Modems and routers

To access the internet, you will need a modem and a router. These are pieces of hardware that are supplied by your internet service provider (ISP). Most providers will offer a modem-router combination. This kind of modem has a built-in wireless router that connects your devices to the internet.

A modem gives you access to the internet and a router connects your devices to the modem. A router shares your internet connection with your wireless devices, such as phones, laptops and tablets.

A router may be wired or wireless. A wired router is connected to your computer or laptop using an ethernet cable to access the internet. It sends information between your network and the internet. With a wireless router, the computer connects to your network using radio signals instead of cables.

To get the best out of your broadband internet connection, position your wireless router somewhere it will receive the strongest signal with the least amount of interference.

• You could place the router near the centre of your home to increase the strength of the wireless signal throughout your home.

• You should position the wireless router off the floor and away from walls and furniture. The fewer physical obstructions between your computer and the router’s signal, the more likely you’ll be using the router’s full signal strength.
