circuit and packet switching

Question 1

what is a data packet?

Answer 1

When sending data across a network, files are broken down into smaller parts called data packets.

Question 2

Advantages of packet switching

Answer 2

More secure- data packets take different routes, so is harder for a hacker to intercept.
If a device fails the data packets can take another route
Data packets can be sent efficiently and individually across less busy routes.

Question 3

Disadvantages of packet switching

Answer 3

Reassembling the data takes longer because the packets may arrive out of order.
It is less reliable than circuit switching as some data packets may not reach the destination (packet loss)

Question 4

Advantages of circuit switching

Answer 4

Reassembling the data is quick because the packets arrive in the order that they were sent.
It is more reliable than packet switching because data is sent in 1 continuous stream.
The transmission is fast, should have fewer errors.

Question 5

disadvantages of circuit switching

Answer 5

Reassembling the data is quick because the packets arrive in the order that they were sent.
It is more reliable than packet switching because data is sent in 1 continuous stream.
The transmission is fast, should have fewer errors.
