Input devices
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, much like a TV. Mouse, keyboard and Joystick is an example of an input device. Below is a list of all the different computer input devices that can be used on a computer.
Mouse- is a hardware input device that was invented by Douglas Engelbart in 1963 while working at Xerox PARC, who at the time was working at the Stanford Research Institute, which was a think tank sponsored by Stanford University. The mouse allows an individual to control a pointer in a graphical user interface (GUI) and manipulate on-screen objects such as icons, files, and folders. By using a mouse the user doesn't have to memorize commands, like those used in a text-based command line environment such as MS-DOS. For example, in MS-DOS a user would have to know the cd command and dir command to navigate to a folder and view the files. However, in Windows the user only has to double-click on the folder to view all the files.
Keyboard- One of the primary input devices used with a computer, the keyboardlooks very similar to the keyboards of electric typewriters, with some additional keys. Keyboards allow a computer user to input letters, numbers, and other symbols into a computer and is what allows you to write e-mail and is what you used to visit this web page. Below is an example of a Saitek keyboard with indicators pointing to each of the major sections of the keyboard.
Optical scanner- is a hardware input device that allows a user to take an image or text and convert it into a digital file, allowing the computer to read or display the scanned object. A scanner can be connected to a computer using USB, Firewire, Parallel, or a SCSI port. Other scanners include: sheetfed scanner, which is a scanner that scans paper fed into it, handheld scanner, which is a scanner that is held and drag over a page
