Solution

The correct option is A Frame

A group of bits representing a block of data is called Frame

Two words commonly used in networking world - Packets and frames. Can anyone please give the detail difference between these two words? A packet is the PDU - protocol delivery unit at layer 3 (network layer - ip packet) of the networking OSI model. A frame is the PDU of layer 2 (data link) of the OSI model.

To address every byte in an 8K frame, you need 13 bits. The second one is a bit more iffy. Although you may have 32 bits available to you in a "word", the question asks how many bits you require for a 1G address space (not the 4G you'd normally get from 32 bits).

A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet." Each frame is separated from the next by an interframe gap. A frame is a series of bits generally composed of frame synchronization bits, the packet payload, and a frame check sequence.
