Printer
Question # 12
Thick ethernet also requires to avoid signal reflectance.
Terminators
Question # 13
The field of ethernet frame has the purpose of frame payload.
Data
Question # 14
In technique all members of network can send data only on the specific time slot?
TDMA
Question # 15
In Star Topology all computers are attched to a central hub.
Question # 16
IEEE 802.11 is standard wireless LAN that uses radui signals at 2.4GHz.
Question # 17
In Bus Topology terminators are used at the end of the cable
Question # 18
A network uses Ring Topology to arrange computers in a single closed loop.
Question # 19
Lan interface uses DMA to copy frame data directly from main memory.
Question # 20
In direct point to point communication adding the Nth computer requires N-1 new connections.
Question # 21
In CSMA technique all members of the network can send data only on the specific slot
Question # 22
FDDI uses counter rotating rings in which data flows in opposite directions
