About Lesson
The bus is the communication pathway used to transfer data between various components of the computer system, such as the CPU, memory, and input/output devices.
Types of Buses:
- Data Bus: Carries the actual data between components.
- Address Bus: Carries the address to or from which data is being transferred.
- Control Bus: Carries control signals that direct the operation of the CPU, memory, and peripherals.
I/O Architecture:
- I/O Devices: Devices used to interact with the computer, such as keyboards, mice, printers, and displays.
- I/O Ports: Physical or logical connections through which input and output devices communicate with the CPU.
- Direct Memory Access (DMA): A method that allows peripheral devices to communicate directly with memory without involving the CPU.
