What is a wedge on the keyboard?
Keyboard Wedge is an interface that allows the device without a key to connect to the computer as if sending the keyboard data. Since most data input software is set to take data from the keyboard, you need to use the keyboard wedge, if you want to connect peripheral, such as a barcode scanner or a magnetic strip reader and send it to the program. The keyboard wedge is called because the physical version of the "wedge" between the keyboard and the computer. The keyboard is connected to the wedge, which is in turn connected to the computer so that the data can be entered either by a keyboard or other peripheral. There are also software versions of the keyboard wedge. These programs take information sent by an external input device, usually connected via COM or USB ports, and send it via the operating system keyboard, so the computer thinks that the information has been sent via the keyboard.
Keyboard keyboard can be usefulWhen using peripheral software for which the software has not been intended. While some data input software is written specifically with barcode scanners or magnetic belt readers, most are written provided the keyboard is the only device used to enter data. For efficiency, however, many businesses use barcodes instead of manually entering the unit code, and since most people do not read barcodes, some method of converting barcode to its constant information and transmission to the computer because alphanumeric data was needed. The keyboard keyboard was developed in the first days of calculation by a programmer in Altek Instruments in Britain. To date, Altek tools remain one of the primary manufacturers of hardware wedge systems.
The older keyboard wedges are created to connect to the computer via the PS/2 port, because this is the tradition of the Al. Newer versions of the keyboard wedges usually offer an interface for both the PS/2 cable and the US cableB because USB keyboards are still becoming standard. Some keyboard wedges are created to connect proprietary ports such as Port 17 or OCIA IBM. This type of wedge on the keyboard is becoming increasingly difficult to find, but small companies still exist to fill the niche.
