16,382

8,190

4,094

2,046

Question 3. The packets switching concept was first proposed

in the late 1980s for the Defense Ministry of US.

in the early 1960s for military communication systems, mainly to handle speech

in the late 1950s for Defense Ministry of US

none of the above

Question 4. If the ASCII character G is sent and the character D is received, what type of error is this?

single-bit

multiple-bit

burst

recoverable

Question 5. Satellite-Switched Time-Division Multiple Access (SS/TDMA) is

the method of determining which device has access to the transmission medium at any time.

a medium access control technique for multiple access transmission media

a form of TDMA in which circuit switching is used to dynamically change the channel assignments

all of the above

Question 6. If delays are recorded as 10 bit numbers in a 50 router network, and delay vectors are exchanged twice a second, how much bandwidth per fill duplex line is occupied by the distributed routing algorithm?

500 bps

1500 bps

5 bps

1000 bps

Question 7. Which of the following provides a storage mechanism for incoming mail but does not allow a user to download messages selectively?

1950, USA

1950, Japan

Question 9. Which of the following statement is incorrect?

if a host moves from one network to another, its IP address must change

routing uses the network portion of the IP address, the path taken by packets travelling to a host with multiple IP addresses depends on the address used.

IP addresses encode both a network and a host on that network, they do not specify an individual machine, but a connection to a network.

all of the above
