Serial Buses

Serial communication

sending data one bit at a time, sequentiallly
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
