Bus Architecture refers to a system design that allows different components of a computer, such as the CPU, memory, and input/output devices, to communicate with each other. It consists of a set of physical connections, or "buses," that transmit data, addresses, and control signals. This architecture enables efficient data transfer and coordination among various parts of the system. In a typical bus architecture, there are three main types of buses: the data bus, which carries the actual data; the address bus, which specifies the location of the data; and the control bus, which manages the operations and timing of the data transfer. This structured approach simplifies the design and enhances the performance of computer systems.
