tastaturport

A tastaturport, or keyboard port, is a physical connector on a computer or electronic device used to connect a keyboard. Historically, several types of tastaturports have been common, each with its own advantages and disadvantages. The most prevalent in early personal computers were the DIN and AT connectors. The DIN connector, typically a 5-pin round plug, was widely used for keyboards and other peripherals. The AT connector, also a 5-pin round plug but physically different from the DIN, became standard with the IBM AT computer and remained dominant for many years.

Later, the PS/2 connector emerged as a successor to the AT connector. PS/2 ports are also round and typically color-coded, with purple for keyboards and green for mice, to prevent accidental misconnections. While more compact than their predecessors, PS/2 connectors are not hot-swappable, meaning the computer must be turned off before connecting or disconnecting a keyboard to avoid potential damage.

In modern computing, USB (Universal Serial Bus) has largely replaced dedicated keyboard ports. USB ports offer greater versatility, supporting hot-swapping, higher data transfer rates, and the ability to power connected devices. Most contemporary keyboards utilize a USB Type-A connector, although other USB types like USB-C are becoming increasingly common. The transition to USB has simplified connectivity and reduced the need for specialized ports on computers.
