38. Option A
A Round Robin protocol is a protocol in which each workstation takes a turn at
transmission, and the terms are uniformly distributed over all workstations.
39. Option B
If a receiver has just received one packet of data with bytes numbered 600 to 700,
it will respond immediately with an ACK of 701.
40. Option A
The MAC (Medium Access Control) sublayer is primarly responsible for logical
addreressing and providing srror control and flow control information.
41. Option C
A 10BaseT system transmits 10-Mbps baseband(digital) signals over twisted pair for a maximum of 100 meters per segment length.
42. Option D
100BaseFX was the standard created for fibre-optic systems.
43. Option B
Local area networks can cover large geographic distances,including the entire earth.
44. Option D
The most popular contention based protocol is Carrier Sense Multiple Access with collision detection(CSMA/CD).
45. Option B
The interval during which the signal propogate down the bus and back is the Collision window.
46. Option C
In CSMA/CA, the amount of time a device is made to wait before it can transmit is called the Interframe space(IFS).
47. Option A
A Hub is a device that conncects two or more workstations in a star-wired bus local area network and immediately retransmitts the data it receives from any workstation out to all other workstations connected.
48. Option C
A transparent bridge creates the internal port table by using a form of Backward learning.
49. Option C
In a cut-through architecture,the data frame begins to exit the switch almost as soon as it begins to enter the switch.
