Advanced Topic 43 of 51 Computer Architecture & Logic

Bus Architecture

Shared pathways carrying data, address and control signals.

How it works

Buses are shared sets of wires for address, data and control. Modern systems use point-to-point serial links (PCIe, UPI) in place of wide shared buses for speed.

Where it is used

Connecting CPU, memory and peripherals.

Common pitfall

Shared buses become bottlenecks and need arbitration.

Where it fits in the course

Bus Architecture is topic 43 of 51 in Computer Architecture & Logic, rated Advanced. It follows Interrupts. The next topic is Storage Devices.
