Item no. 328
Description
| There are a number of ways to connect external peripherals to a computer. The main interfaces are differentiated as follows: | |
| ADB-Plug (only for Apple Macintosh Computer): | |
| The Apple Desktop Bus (ADB) is an interface standard defined by Apple for connecting external devices to a computer. Today USB completely replaces the ADB connection. | |
| AT- XT-Plug | |
| The XT and AT keyboards share the same electrical interface, except that the bi-directional interface allows the AT keyboard to receive commands from the motherboard. However, they are incompatible on the logical interface (the AT keyboard sometimes has an XT / AT mode switch). | |
| Bluetooth: | |
| Bluetooth enables wireless connections through radio-based data transmission. Bluetooth is used in particular for communication between PCs and cell phones or other small mobile devices. It can also be used to connect to printers, hands-free kits or digital cameras, or for communication between several computers. With the help of Bluetooth USB adapters, every PC can be made Bluetooth-enabled. | |
| PS/2-Plug | |
| Before USB established itself as a general-purpose interface, mice or keyboards were also connected to the PC via PS2 ports. Many of our keyboards are available with both PS / 2 and USB. | |
| Serial-Plug | |
| Older computers have one or more serial interfaces whose English designation COM port is also common. They are 9-pin or 25-pin and are characterized by the fact that they send or receive the data one after the other. Since the serial interface has relatively low data transfer rates, it was mainly used for mice or modems that do not require high bandwidth, and it is now rarely used. | |
| USB-Plug | |
| USB is the abbreviation for Universal Serial Bus. This interface was brought to market by Intel and Microsoft. With USB, almost any device can be connected without special settings. |
