Topology in computer science refers to the arrangement of computers, devices, and network components within a system. It defines how different nodes (computers, servers, routers, etc.) are connected and communicate with each other in a network. The topology affects the efficiency, performance, and reliability of a network. Types of Network Topology There are several types of network topology, each with its own structure and advantages: 1. Bus Topology - All devices are connected to a single central cable (bus). - Data travels in both directions along the bus. - Example: A small office network where all computers share a single communication line. 2. Star Topology - All devices are connected to a central hub or switch. - The hub acts as a communication point between devices. - Example: Home or office Wi-Fi net...
