What do you mean by network architecture?

Network architecture is the complete design of a computer network. It specifies how the hardware, software, protocols and connection methods are organised so that devices can communicate.

It includes:

  • Layered protocol structure with the services and interfaces between layers (OSI and TCP/IP models).
  • Physical topology such as bus, star or ring.
  • Functional organisation of the network, for example client-server or peer-to-peer.
  • Transmission media, devices and addressing schemes.

A good architecture gives reliability, performance, scalability and security. For example, the TCP/IP architecture defines four layers and the protocols at each layer.
