About Lesson
Interconnection structures are essential for enabling communication between different components of the computer system.
7.1 Bus System
- The bus system is used to transfer data between the CPU, memory, and I/O devices. It includes the data bus, address bus, and control bus, as previously mentioned.
7.2 Direct Memory Access (DMA)
- DMA allows peripherals (like disk drives) to directly access memory without the need for the CPU to intervene. This increases the speed and efficiency of data transfers.
7.3 Interrupts
- An interrupt is a signal from a hardware device (or software) that temporarily halts the CPU’s current operations to handle the new event, allowing for more responsive systems.
