How PS/2 Ports Work?
- Connection: It is closed with about 6 pins called the pin set/ 2, and each of the pins has the function of a power pin, grounds pin, clock pin, transmitting of data, etc.
- Data Transmission: There is only one stream for the data pin per bit and it runs from the keyboard or mouse and alongside the clock signal for the transfer.
- Interrupts: Influenced through the high concentration and processing of input signals for the PS/2 port, IRQ, or interrupt requests, used for informing the computer’s CPU at the right time.
What is PS/2 Port?
The PS/2 port is an interfacing technology essentially used to connect keyboards and mouse to a computer. First developed by IBM in 1987 following their PS/2 line of PCs, this interface succeeded in becoming an industry standard through the 1990s and on into the first decade of the current millennium.
Although USB interfaces are widely used in contemporary systems and interfaces, there are still systems with PS/2 ports, especially in systems based on legacy hardware. The article sums up the basic information concerning the PS/2 port, definitions of basic terms vital for working with the port, the stages of attaching/disconnecting, and key problem-solving.
