What does the term "network topology" refer to in system design?

Network topology refers to the physical or logical arrangement of various elements in a computer network. This includes the layout of devices such as computers, switches, routers, and the way they are connected to each other. Understanding network topology is crucial for efficient network design and management since it impacts performance, reliability, and maintenance.

Different topologies, such as star, ring, bus, and mesh, dictate how data flows through the network and can influence factors such as redundancy and fault tolerance. By determining the configuration of the network elements, designers can ensure that the system meets the required performance benchmarks and operational criteria.

The other options, although related to networking, do not define what network topology is. Security protocols are concerned with safeguarding data and communication, data transmission speed relates to performance metrics, and networking cables pertain to the physical components used for connections rather than the organizational structure of the network itself.
