Bandwidth
by Liam East on Apr.28, 2010, under Uncategorized
- Bandwidth is the amount of data that can be sent over a period of time. Bandwidth is usually measured in bits per second (bps).
- when data is sent, it is split up into “packets” and in each of these packets is a header. The header contains information from where the data was sent, where the data is going to and how all the packets are going to be put back together again when the data reaches its destination.
- Imagine a motorway with cars on it, obviously the wider the motorway, the more cars can travel on it at one time, so therefore cars can get to their destinations quicker. So think of that, but in computer terms, the more bandwidth, the more information can be transferred within that period of time.
- Another real life example of bandwith is a pipe, the wider the pipe gets the more water can get through the pipe, the water wont go through quicker, its just lets more water through the p
ipe, within the same amount of time.
