USB (in English USB and Universal Serial Bus) is a serial bus standard in the field of information technology. This device is used to create an intermediary between devices and computers. This bus was developed in order to provide a way to connect a large number of peripheral hardware through a standard interface port, as well as to improve connection and performance capabilities. This protocol is presented in three versions: 1.1, 2.1, 3.0.
The VGA (D-Sub) port is a 15-pin port that was designed and standardized by IBM in 1987. This port is used to transfer images from the computer to devices such as monitors, data projectors, televisions, etc. (D-Sub is also known as DE-15.
DVI stands for Digital Video Interface and is one of the highest quality types of connections. By using this port, you will not have any loss of image quality. This digital connection of images can be connected to systems that have HDMI output only with the help of an adapter. It can also be used to connect the TV to the computer, for which a special cable including a multi-pin socket is needed.
Hard Disk (HDD)
