Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which of these are NOT protocols?

A	ITMAP
B	POP
C	HTTPS
D	FTP

Explanation:

Detailed explanation-1: -Bit-map protocol is a collision free protocol that operates in the Medium Access Control (MAC) layer of the OSI model. It resolves any possibility of collisions while multiple stations are contending for acquiring a shared channel for transmission.

Detailed explanation-2: -Backup Route Aware Routing Program (BRAP) is a protocol that provides interdomain routing. BRAP uses reverse paths and backup paths to ensure fast failure recovery in networking systems. One problem with Basic Bit-Map Protocol is that the overhead is 1 bit per frame per station.

Detailed explanation-3: -Limited Contention Protocols are the media access control (MAC) protocols that combines the advantages of collision based protocols and collision free protocols. They behave like slotted ALOHA under light loads and bitmap protocols under heavy loads.
