Study Notes
PS/2 Connectors
- PS/2 connectors have a 6-pin mini-DIN color code: green for keyboard, purple for mouse.
Legacy Ports
- PS/2 ports are considered legacy ports because they are outdated and have been replaced by newer technologies such as USB.
DE-9 Port
- The port often miscalled as DB-9 is actually a DE-9 port, which is a 9-pin serial port.
Parallel Port
- The main purpose of a parallel port or Centronics port is to connect devices such as printers.
- The primary reason behind developing the DE-9 port is to reduce the number of pins from the original DB-25 port.
DB-25 Port
- Many applications did not require all the pins in the DB-25 port, which led to the development of smaller ports.
Computer Port
- The main function of a computer port is to connect devices to a computer.
- Another name for a computer port is a computer interface.
Serial Port
- Data is transferred in a serial port one bit at a time through a single wire.
- The connector type commonly associated with serial ports is a DE-9 connector.
Parallel Communication
- Parallel communication involves transferring data in parallel using multiple lines, increasing the speed of data transfer.
Peripheral Devices
- An example of a peripheral device connected through a parallel port is a printer.
