Study Notes
Bus Architecture
- The control bus carries control signals that manage data transfer between components.
- The bus size is determined by the number of bits that can be transmitted simultaneously.
Address Bus
- The address bus is a unidirectional bus that carries memory address from the CPU to the memory.
- It is often referred to as the memory bus.
Bus Speed
- Bus speed is measured in megahertz (MHz), which represents the number of times data is transferred per second.
Data Transfer
- A single transfer of data, whether sent or received, is called a cycle or clock cycle.
