3.1.11 - Explain how data is transmitted by packet switching.

Question 1

What is packet switching?

Answer 1

Packet switching is a method of grouping data into packets that are transmitted over a digital network, with each packet containing a header and payload.

Question 2

How is data divided in packet switching?

Answer 2

Data is divided into small, fixed-size packets, each containing a portion of the original data along with header information.

Question 3

How does routing work in packet switching?

Answer 3

Each packet is routed independently through the network based on its header information. Routers make dynamic routing decisions to determine the best path for each packet.

Question 4

How are packets transmitted and reassembled in packet switching?

Answer 4

Packets are transmitted individually, potentially taking different paths and arriving out of order. Upon arrival, the receiving device reassembles them into the original data using information from the packet headers.
