Q

what does the DNS stand for

A

domain name system

17
Q

what is the DNS

A

the name given to the method of naming internet resources(.com , uk)

18
Q

what is circuit switching

A

the process of creating a direct link between two devices and transferring data the entire duration of the link

19
Q

what is a requirement of circuit switching

A

the transfer and download rates must be identical on both devices

20
Q

what is packet switching

A

a method of communicating packets of data across a network

21
Q

give an advantage of packet switching

A

-multiple methods to ensure data arrives correctly
-multiple methods to arrive to destination, if one breaks you can always go through another route
-transfer packets over a very large network

22
Q

give an disadvantage of packet switching

A

time is spent deconstructing and reconstructing the packets

23
Q

give an advantage of circuit switching

A

data arrives in logical order which results in a quicker reconstruction of data
-enables two users to hold on a call without any delay in speech

24
Q

give two disadvantages of circuit switching

A

-bandwidth is wasted during periods when no data is sent
-devices must transfer and download at the same rate
-switches introduce electrical interference which can corrupt or destroy data

25
Q

what does the header of a data packet contain

A

-the sender and recipient IP address
-protocols being used
-order of the packets
-the time to live

26
Q

what does the packet payload contain

A

raw data

27
Q

what does the packet trailer contain

A

checksum or cyclic redundancy check

28
Q

what is a client server networking

A

a relationship between terminals (computers) and a single server which allows them to communicate and share resources

29
Q

give an advantage of client server networking

A

-increased security
-central single backups
-data and resources can be shared

30
Q

name a disadvantage of client server networking

A

-expensive to set up
-trained staff are required to maintain the network

31
Q

what. is a peer to peer network

A

a network where the terminals are all connected to each other to share resources

32
Q

give two advantages of peer to peer networks

A

-cheaper to set u
-easy to share resources
-easy to maintain

33
Q

give tw disadvantages of peer to peer networks

A

can reused to contribute towards piracy
-each computer has to be backed up independantly
