A computer is a set of systems with its hardware components which are connected using different types of computer ports. All parts of computer hardware have their specific functions. In which, one of the can work to process data and delivers information, one works to storage data from another device or data processing work to the computer, while another one works to display graphic or visualize data.
Some of that computer hardware components or devices have a particular type of port to maximize their functions. Your computer ports can connect your computer to a number external hardware device and other hardware utilities to sync with your computer properly.
There are ten types of computer ports that we usually use on our computer, as well as the functions of each of them are different. The following are the ten types of computer ports.
A parallel port is widely used to connect a computer to a set of parallel printers, zip drives, and external hard drives. This type of port uses a DB-25 connector with 25 pins. Again, the use of the parallel port is also quite rare as it’s less practical if it’s compared to a USB port.
In the fifth generation computers, serial ports are rarely used, given that most of the today’s computers use standard USB ports to connect many types of computer hardware devices.
The functions of USB ports on a computer can displace the role of the serial and parallel ports because standard hardware devices support USB connection. Today’s computers even don’t support serial and parallel ports anymore, which makes computers more tiny, practical, and simple.
A USB port has many functions, such as connecting any data storage device, mouse, keyboard, data transfer between computer and flash or portable hard disk, and even charging gadgets. The universal function of the current USB port is not only available for PCs or laptops, but it is widely used in many types of media players, televisions, mobile phones, and head unit in a car.
The primary function of a VGA port is to transmit the graphic data from the computer to the screen display or output. The screen display or output that can be used is a screen display monitor, television, and projector. However, the downside of VGA port is its connector cannot transmit voice signal.
A standard computer usually supports only one audio port for producing a stereo output. However, on a computer with a more sophisticated soundcard, it supports sound output from 5.1 to 9.1 for specific purposes.
The functions an HDMI port are the same as a VGA Port. However, HDMI is capable of transmitting media with HD quality and can transmit voice signals. HDMI port is currently an option you can use to display a computer graphics on particular types of computer monitors such as large TV monitors or large projectors.
As what has been mentioned above, the primary role of all types of computer ports is to connect the computer to a certain external hardware component or device. Most of the fifth generation of computer computers still use one of the types of cables to plug in a hardware component or device to the computer. For examples, USB port, the keyboard port, HDMI port, etc. But for a more remote device use, some fifth generation computers have been developing to realize wireless devices interconnection in making the applications of a computer becoming more mobile. Furthermore, it will be possible the wireless devices interconnection of the sixth generation of computers becomes more familiar.
