In CRC G =

Parity Check technique is suitable for detecting ___________ number of bit error

Each of the CRC standards can detect burst errors of ______ r + 1 bits.

.................... such as that found between two routers connected by a long-distance link, or between a user's office computer and the nearby Ethernet switch.

if number of bits in the packet = 15 , transmission rate = 3 Then Packet transmission delay =

Bidirectional multiple frequency channels on cable.

Coaxial cable used

Fiber Optic supports:

has a single light path and is used commonly for high-speed :. transmission over long distances

Radio has the following characteristics

Internal modem is separate from computer.

Hub has the transmission mode of

Hub provide extra security .

often has an antenna.

Network layer has responsibility of transferring datagram from one node to physically adjacent node over a link.

Broadcast channels: connect multiple hosts in access networks.

PPP is

with half duplex, nodes at both ends of link can transmit, at same time.

the sending controller performs error detection based on error checking bits that were added by the sending controller.
