its an input hardware just like a mouse or keyboard
It is an input device.
Input
I'm pretty sure it's an input. The computer registers the input of the rotation of the ball, than the mouse on the screen moves, that being the output.
input, output, storage, hardware
The trackball would be an input device. Any device that takes information from the outside world into the computer is an input device. Any device that takes information from the computer and gives it to the outside world (such as a monitor or printer) is an output device.
Input, output, PROCESS, and Storage
Depends. There are hardware which are input and hardware that are output. eg:Input hardware:ScannerMicrophoneCD player (Not CD-RW)Output hardware:SpeakersPrinterMonitor
They're both! Monitors are output devices and so are printers. A common input devices would be keyboards or mice and all are considered hardware.
Neither. A computer contains both input and output devices. Many modern input and output devices contain embedded computers, that interface between the main computer and the actual input or output hardware of the device.
Yes, a trackball is an input device.
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.
Input, output, processing, storage.
