Wired Keyboard

A keyboard connected directly to a computer via USB or PS/2 cable. Power and data transfer happen through the physical connection, eliminating batteries and wireless interference.

Connection Type

USB or PS/2 (wired)

Power Source

Computer USB port

Latency

Sub-1ms typical

Range

Limited to cable length

Pros

  • Zero input latency and consistent response time
  • No batteries required; unlimited usage without charging
  • No wireless interference or connectivity dropouts

Cons

  • Cable clutter and reduced desk mobility
  • Less flexibility in keyboard placement
  • Cable wear and potential damage over time

Wireless Keyboard

A keyboard that communicates with a computer via radio frequency (2.4 GHz) or Bluetooth. Powered by internal batteries or rechargeable cells, offering freedom from cables.

Connection Type

2.4 GHz RF or Bluetooth

Power Source

AA/AAA batteries or rechargeable

Latency

1–10ms typical

Range

30–100 feet typical

Pros

  • No cables; clean desk aesthetics and greater mobility
  • Flexible placement up to 30+ feet from receiver
  • Many models feature rechargeable batteries or extended battery life

Cons

  • Requires regular battery replacement or charging
  • Slight input lag (typically 1–10ms) due to wireless protocol
  • Potential interference from other wireless devices
