Serial Communication/Buses
Sending data one bit at a time, sequentiallly
Benefits
- Improved signal integrity and transmission speeds in short distances have outweighted parallel buses
- Modern example: PCIe, sned data several bits at a time via modulation/encoding
- Long distance generally sticks to serial over parallel to reduce cost of cable
- Examples:
- PS/2 port: 6-pin mini-DIN connector used for connecting keyboards and mice to a PC
- USB: universal serial bus
