Packets:
1.
What is a
packet?
A small chunk of data which is part of a bigger piece of data
e.g. an image, word document etc
2.
Why are
packets used?
Packets are used because they are more reliable and take a lot
less time because they are smaller and are less likely to collide; even if they
collide the computer will just resend the data, whereas if u send just all the
data at once, it will have to keep resending every time there is a collision so
will take a very long time.
3.
How does
sending information with packets work?
The big piece of data is cut up into smaller ‘packets’ of data
and sent across the network to the location its sent to ( the address it has
written on it), if a packet of data collides, it is resent and once all the
pieces of data have arrived at the destination, they will be put back together.
