Question

peter wants to make a computer, but doesnt have the money to buy a cpu. he only has the money for a keyboard, ram (random access memory), and monitor. why is the cpu important? choose 1 answer: a without a cpu, the computer cant power the monitor. b without a cpu, there is nowhere for the computer to store data for later retrieval. peter wont be able to store files. c without a cpu, the computer cant process the data that comes from the keyboard. d without a cpu, the computer cant turn the keyboard data into binary data.

Explanation:

The CPU (Central - Processing Unit) is the brain of the computer. It processes instructions and data received from input devices like the keyboard. Option A is wrong as powering the monitor is mainly related to the power supply and graphics - related components. Option B is incorrect because data storage for later retrieval is mainly the function of storage devices like hard drives or SSDs, not the CPU. Option D is wrong as the conversion of keyboard data into binary is often done by input - device drivers and some basic circuitry in the input device itself, not the CPU's main function in this context. The CPU's primary role is to process data from input devices, so without it, the computer can't process the data that comes from the keyboard.

Answer:

C. Without a CPU, the computer can't process the data that comes from the keyboard.
