It can transfer large amount of data at very high speed. The IEEE 1394 interface, which is developed in the late 1980s and early 1990s by Apple as FireWire. Microphones and speakers are connected with the help of Sockets to the sound card of the computer. But VGA Ports have holes in it and the serial port connector has pins in it. VGA port has 15 holes and it is similar to the serial port connector. VGA ports also known as Video Graphic Array connector are those which connect the monitor to a computer’s video card. In old computers, there are minimum of two PS/2 Ports, each for the keyboard and the mouse. PS/2 ports are special ports used for connecting old computer keyboard and mouse. It also provides plug & plays communication. The data transfer rate in this is Data12 megabits per second. It is a kind of new type serial connection Port that is much faster than the old serial Ports and These USB Ports are much smarter and more versatile, as it allows the “daisy chaining” of up to 127 USB peripherals connected to one port. There are minimum of two USB Ports provided in most of the computer systems. This can connect all kinds of external USB devices, like external hard disk, printer, scanner, mouse, keyboard, etc. It is also known as Printer Port or Line Printer Port. Its data transfer speed is much higher in comparison with the serial port. It can send several bits at the same time as it uses parallel communication. Parallel ports are generally used for connecting scanners and printers. There are two versions of it, which are 9 pin model and 25 pin model. Serial cables are cheaper to make in comparison to parallel cables and they are easier to shield from interference. Now let us discuss these ports one by one:Ī serial port is also called a communication port and they are used for connection of external devices like a modem, mouse, or keyboard (basically in older PCs).
There are different types of ports available: Or in other words, a port is an interface between the motherboard and an external device of the computer. The ports are the physical docking points present in the computer through which the external devices are connected using cables. Now, these devices are connected with the computer using Ports. As we know that we can connect multiple external devices with the computer system. It processes the input according to the set of instructions provided to it by the user and gives the desired output.
