Bandwidth BY ADAM GREENHALGH
Bandwidth is a computering turn of how quick a peice of data gets tranfererd. It measures in bits per second also knowas bps. It also represents the distance of the highest and the lowest signals. It will measure the capity there bigger the capicity you will get a better performance. However if you are trying to send some data and you do not have enough bandwidth somewhere along the way you will have to swich you data.
Here is a table to show some speeds
usb 1.1 =12mbps 2.0 =480 mbps 3.0 = 4.8 Gbs
ilink 1394a = 400 mbps 1394b = 800 mbps
ethernet 802.3 =10/100/1000 mbps
wi-fi 802.11 a = 54 b=11 g= 54 n =540
bluetooth 1=1 mbps 2= 2.1mbps

Networks
In the chapter we are learning about it is all about networks. The two main types of networks are WAN and LAN. lan stands for local area network and the kind of places that you would find LAN would be a house school or a little buisness.The WAN stands for wind area network and the kind of places that you would be able to find this would be in would be the internet. There are many different ypes of networks that you can connect to these are desktop computers, laptop computers, printers, scanners and many other things. You can link a netwok to one of these things by using these cables : copper cables which use eltrical signals to transfer data, fibre optical calbling this uses glass and plastic wire which is also known as fibre to transfer there data, the last one is wireless connection which you do not need wires for and it canuse radio singnals to tranfer there data. There is also another type of network that is quite popular and this is called WLAN this stands for wireless local area network. there is another network but it is not as good this is a peer to peer network this is a network that has know administrator which means know body owns it so knowone has the power to shut it down if they wanted to.
