1. Task 2 – Computer Networking By Hope Oliver 9D.
1.How do information packets get from one computer to another within a
single network?
To make computer’s job easier, they break down the information into small
chunks called packets, including emails, chat systems, etc. Each packet
travels along the Internet on its own, making its way to its destination.
When the packets reach where they need to be, they are put back together.
Sometimes, packets get lost along the way, and sometimes they join other
packets on the way by mistake. The packets travel through machines called
routers, which kind of acts like a traffic cop. The routers direct which way
the information should go.
2. How many routers does a packet have to pass through to get from
one side of the model to the other?
A packet has to pass through numerous routers to get from one side of the
model to the other.
3. What would cause a traffic jam (or bottleneck) at a router?
Sometimes it may occur that many packets arrive at a router at the same
time. This is when a traffic jam happens, called a bottleneck. Some packets
get through straight away, however some are left to wait for their turn.
This is what causes emails to have a delay. The good thing is, routers find
out about this and there are always other routers to back them up, so the
connection never really fails.
