It can be many things. Input means a device that send information to the computer, like a mouse, scanner, microphone, etc.
mouse or keyboard.
This would depend on what type of computer you are discussing... - For a personal computer (Desktop) or a Laptop this would be a keyboard followed closely by a mouse or … touchpad . - For a tablet this would be the touch screen .
mouse, keyboard, microphone, scanner, card reader, sensor array, thumbprint reader, or anything you use to input information into a computer. Components typically comprise …a human-activated switch, electrical signal generating device and wiring to a standardized connector to plug into a computer. For example, a keyboard is a matrix of keycaps, each having one or more electrical contacts, arranged to encode a keycap location as a set of signals to the computer, where the signal is sent by way of a cord containing wires. Some keyboards are "wireless" and use infrared or other wireless signals. Some keyboards contain additional encoding devices that allow them to use a standardized interface, such as USB.
Thumbdrive is an input component.
An input device is a keyboard, for example.
Microsoft DirectInput 5.0 and later versions communicate directly with the HID class driver. Vendor-supplied function drivers are not required to support DirectInput applicati…ons that access HIDClass devices. In addition, DirectInput applications do not have to interface directly with a HIDClass device to benefit from the full functionality of the device. DirectInput 7.0 and later versions support physical input devices (PIDs), as defined by the USB HID Standard. Applications that use only the Microsoft Windows multimedia DLL ( winmm.dll ) can indirectly access HID joysticks because winmm.dll accesses joysticks through DirectInput COM interfaces. The physical attachment of a joystick is transparent to a Windows multimedia application. The Microsoft Win32 subsystem DLLs ( user32.dll in Windows 2000 and later versions, and user.dll in Windows Me) access keyboard and mouse class devices through the drivers for non-HIDClass keyboard and mouse devices.
Keyboard, Mouse, Joystick, barcode readers etc etc
HD television signals are always in a component format. There are three signals that between them carry brightness and color information. Almost all domestic equipment uses an… HDMI interface to carry the signal in a digital format now but there is also an analog HD component standard. The analog component connector is either on three RCA connectors or three BNC connectors. Pressure from the film and television industry has persuaded manufacturers to adopt HDMI as the only HD interface on modern equipment. As a result, HD analog component inputs to displays are virtually redundant now.
Testing a specific part of a system or even a program. That would be called a component. So it is component testing.
