What are networks?

There are different sort of networks : social networks, computer networks etc. Facebook for example is a social network, anyone can sign in, create there own profile, enter their name, interests, and then chat with friends, share videos, comments, thoughts etc. And other well known network is Twitter, which is used a lot by americans. A network of computers is when several computers are linked up and can share information. You can have this at different scales, for example the internet is a computer network, everyone connected to it is part of it. Data gets sent to our computer to others and the same happens on the other side. You can also have smaller networks, such as at the office or at home, you connect you computers together in order to share documents or store documents on the same area, thats what is called a local network.

Video games are a good example of how networks are used, now nearly every computer game has a multiplayer option, which means you connect on the internet and play against other real players all over in the world. However you can also have LAN games, which is playing with people connected to a small network, often this is done with friends, you meet up, get everyone together and play against each other.

External hardware for video games

You can play most games simply by using your mouse and keyboard, but for certain games it is easier to use a joystick, or a wheel, especially if you are going to play games with planes or racing cars. It will be much more realistic to play with these extra devices. You can also buy remote controls similar to the playstation controls, if you you prefer having the buttons in a different setting. Most of these controls are now wireless and work with most games.
