Moving Data#

Hardware transports information.

Once bits exist and are remembered, they have to move — serialized down a single wire, shifted through a register, or driven onto a shared bus without collisions. Shift registers convert between serial and parallel form, transceivers manage bidirectional buses, and buffers provide the drive and isolation that let signals travel intact.

Sections#

• Shift Registers — Serial-to-parallel and parallel-to-serial conversion.
• Bus Transceivers — Bidirectional drivers with direction control for shared buses.
• Buffers — Drive, isolation, and the three-state output.
