Input Devices
Any input device is any hardware device that sends data to the computer. Without any input devices, a computer would only be a display device and not allow users to interact with it. (Input Device). A couple examples are barcode reader, scanner, keyboard, and even a finger if you’re using it for a touchscreen. Drives such as CD-ROM, DVD, and a floppy disk may be capable of sending the computer information, but they are not input devices. These are considered storage devices. Any information or data that’s entered or sent to the computer to be processed is considered input and anything that is displayed from the computer is output (Input Device). Without input devices, a computer is a brain with nothing to think about. But combined with memory and processing power, they make computers some of the most valuable pieces of equipment in our lives (Perez).
A keyboard is defined as an external input device used to type data into some sort of computer system whether it be a mobile device, a personal computer, or another electronic machine (Business Dictionary). A keyboard ususally includes alphabetic, numerical, and common symbols used in everday transcription (Business Dictionary). There are three diffent keyboard layouts; QWERTY, AZERTY, and Dvorak (Hardware - Input Devices). Beyond standard typing, keyboards have a numeric keypad on the right side of the keyboard. Most of today’s desktop keyboards are enhanced. Enhanced meaning having 12 or more funtions along the top and a set of arrow and additional keys between the typing area and numeric keypad. Function keys are special keys programmed to issue instructions to a computer such as media controls internet controls (Shelly and Vermaat).
