Answer:
To perform a required task, a computer requires several components and instructions. Among the given options, the most essential component for a computer to perform a required task is user instructions. Here's a detailed explanation:
User Instructions:
- User instructions are the commands or guidelines provided by the user to the computer to perform a specific task.
- These instructions can be in the form of input through various input devices or software applications.
- User instructions guide the computer on what actions to take and how to process the data.
- Without user instructions, the computer would not know what task it needs to perform or how to go about it.
Other options mentioned in the question are not as essential for a computer to perform a required task:
Monitor:
- A monitor is an output device that displays the visual output of the computer.
- While a monitor is necessary for visual interaction with the computer, it is not essential for the computer to perform a task. The computer can still process data and perform tasks without a monitor.
Keyboard:
- A keyboard is an input device that allows the user to enter data and commands into the computer.
- While a keyboard is essential for providing user instructions, it is not the most essential component. User instructions can also be given through other input devices or software applications.
Printer:
- A printer is an output device that produces a hard copy of the computer's output.
- While a printer may be required to obtain a physical copy of the output, it is not essential for the computer to perform a required task. The computer can still process and perform tasks without a printer.
In conclusion, user instructions are the most essential component for a computer to perform a required task. Without user instructions, the computer would not know what actions to take or how to process the data. Other components like the monitor, keyboard, and printer are important but not as essential for the basic functioning of the computer.
