Method of slicing digital messages into parcels (packets), sending packets along different communication paths as they become available, and then reassembling packets at destination
|
Detailed explanation-1: -Packet switching is a method of slicing digital messages into parcels called packets, sending the packets along different communication paths as they become available, and then reassembling the packets once they arrive at their destinations (see Figure 8-5).
Detailed explanation-2: -Packet switching is the transfer of small pieces of data across various networks. These data chunks or “packets” allow for faster, more efficient data transfer. Often, when a user sends a file across a network, it gets transferred in smaller data packets, not in one piece.
Detailed explanation-3: -The Transmission Control Protocol (TCP) is a transport protocol that is used on top of IP to ensure reliable transmission of packets.
Detailed explanation-4: -In packet switching, the data is transmitted over a network in the form of packets. These packets have two parts header and payload. These packets are not transferred to the destination using the same route, and hence the given statement is false.
Detailed explanation-5: -The Internet layer is responsible for packaging, addressing, and routing the data.
