In computing, the USB human interface device class ( USB HID class) is a part of the USB specification for computer peripherals: it specifies a device class (a type of computer hardware) for human interface devices such as keyboards, mice, game controllers and alphanumeric display devices . The USB HID class is defined in a number of documents ...
USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The communications device class is used for computer networking devices akin to a network card, providing an interface for transmitting Ethernet or ATM frames onto some physical media. It is also used for modems, ISDN, fax machines, and telephony ...
Superseded. Serial port, parallel port, game port, Apple Desktop Bus, PS/2 port, and FireWire (IEEE 1394) Universal Serial Bus ( USB) is an industry standard that allows data exchange and delivery of power between many types of electronics. It specifies its architecture, in particular its physical interface, and communication protocols for data ...
An image scanner —often abbreviated to just scanner —is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.
A SCSI Peripheral Device Type describes the capabilities provided by a SCSI device. It is a five-bit field in the first byte returned in response to an INQUIRY SCSI command. [ 1] Defined values are: Value. Device type.
Barcode reader. A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [ 1] Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain ...
Even CD-ROMs are not handled by all controllers. Device Type is a 5-bit field reported by a SCSI Inquiry Command; defined SCSI Peripheral Device Types include, in addition to many varieties of storage device, printer, scanner, communications device, and a catch-all "processor" type for devices not otherwise listed.
Windows Driver Model. In computing, the Windows Driver Model ( WDM ) – also known at one point as the Win32 Driver Model – is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model .
