Why is the CPU the most important in a computer?
The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it. Without a CPU, we could not run programs on a computer.
Why is CPU considered as the most important component of the system unit?
The Multitasking Function One particular function for which CPUs are useful is allowing your computer to multi-task. To be entirely accurate, a single CPU does not multi-task . Instead, it switches back and forth quickly between different tasks so it looks like they are all being done at the same time.
What is the most important component of a computer?
