Packet Switching

Packet Switching 

• Packet switched networks are the building blocks of computer
communication systems in which data units known as packets flow across
the networks.
• It provides flexible communication in handling all kinds of connections
for a wide range of applications e.g. telephone calls, video conferencing,
distributed data processing etc...
• Packet switched networks with a unified, integrated data infrastructure
known as the Internet can provide a variety of communication services
requiring different bandwidths.
• To make efficient use of available resources, packet switched networks
dynamically allocate resources only when required.
