Answers
Answer:
The required correct option is (d) System unit, Monitor, Keyboard, Mouse.
Explanation:
Computer:
Any device that can be programmed to follow a set of algorithms and mathematical instructions is a computer.
Of course, the computers we think of today are much more than that—and I don't simply mean devices for playing games and browsing the internet for cat videos!
System unit:
It collectively defines the motherboard and CPU of the computer.
Monitor:
It is the most convenient, cutting-edge, and secure method of sending letters.
It is a tool for output. Because it is a display device, the monitor resembles a television screen. The term "visual display unit" may also be used to refer to the monitor (VDU). 14 inches, 15 inches, 17 inches, 18 inches, 19 inches, 21 inches, 22 inches, 23 inches, 24 inches, 25 inches, 26 inches, 27 inches, and even 36 inches are among the various monitor sizes.
Keyboard:
It serves as a keyboard. Words, numbers, and symbols can be typed using the keyboard. To operate on a desktop computer, users can use it to input data or instructions.
Mouse:
A pointing device is a mouse. The mouse can be used to interact with the computer and is useful for pointing at things on the screen. A mechanical mouse and a contemporary optical mouse are the two different sorts of mice (older).
Therefore, the correct option (d) System unit, Monitor, Keyboard, Mouse.
