Question

Which of the following options describe Information which is sent over networks in small units?
1. Sectors
2. Clusters
3. Packets
4. Frames

Answer 1

Correct Answer - Option 3 : Packets

The correct answer is Packets.

• A packet contains a source, destination, data, size, and other useful information that helps the packet make it to the appropriate location and get reassembled properly.
• The information from the computer is sent over the networks in small units known as packets.
• Data transferred over the Internet is sent as one or more packets. The most common packet sent is the TCP packet.

• The packet is a term first coined by Donald Davies in 1965. 
• It is used to describe a segment of data sent from one computer or device to another over a network.
• The size of a packet is limited, so most data sent over a network is broken up into multiple packets before being sent out and then put back together when received.
• When a packet is transmitted over a network, network routers and switches examine the packet and its source to help direct it to the correct location.
