MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Devices on a TCP/IP network divide data into small pieces, allowing the network to accommodate various bandwidths, to allow for multiple routes to a destination, and to retransmit the pieces of data which are interrupted or lost. Each piece is a packet, a term interchangeable with datagram.

Detailed explanation-2: -In networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them.

Detailed explanation-3: -The network layer The network layer breaks up segments from the transport layer into smaller units, called packets, on the sender’s device, and reassembling these packets on the receiving device. The network layer also finds the best physical path for the data to reach its destination; this is known as routing.

Detailed explanation-4: -IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size. The fragments are reassembled by the receiving host.

Detailed explanation-5: -The TCP stack divides the file into data packets, numbers them and then forwards them individually to the IP layer for delivery.
