yes
It is a Output device as it projects images and text.
No, Mouse is an input device. Because mouse is used to instruct the computer where to point the cursor and anything that is used to instruct computer in any way is an input device. Output Devices show the processed data by a computer for e.g. a monitor shows where the cursor is by processing the input from a mouse.
No, a tablet PC is not solely an output device; it functions as a multifunctional device that serves both input and output purposes. It features a touchscreen for input and can display visuals, play audio, and output text and images. Thus, it combines the roles of input and output devices in one unit.
The Keyboard is an Input Device. It is used to enter text and utilise commands. It is a peripheral.
That would be a keyboard
scanner
A typewriter is primarily considered an input device because it allows users to input text by pressing keys. However, it also functions as an output device since it produces a physical printed document as a result of that input. Therefore, while its main role is as an input device, it has characteristics of both types.
Scanners are input devices. They are taking data into a computer, like a photo or text or reading a barcode etc.
A plotter is a printer. And printers are both output and input devices,because you input data in it and revive data from it. so its an input and output device.
A keyboard is the most commonly used tool for entering text into digital devices.
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.
In context of a PC (personal computer) any device that gives inputs or data to the computer is an "input device" for examplea) keyboard is used to enter text or numbers or commands b) mouse is used to move cursor and select data/text or links (again an input to the computer) c) similarly a scanner scans and inputs data to the computer d) a webcam takes picture and "inputs" or provides information to the computer so all these are input devices Devices that provide or show output, information, content or processed data out for use by a user are "output devices" for example - computer monitor or a screen, printer which output (either display or print) data or information for use by the user are output devices.
