Correct Answer - Option 1 : Processor
The logic followed is:
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. A computer system is a "complete" computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for "full" operation.
Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU) in the form of a microprocessor, along with some type of computer memory, typically semiconductor memory chips.
Thus we can say the microprocessor is the most crucial part of the computer.
Option 1: Processor
Computer processor speed (CPU speed) is one of the most important elements to consider when comparing computers. The CPU is often referred to as “the brain” of your computer, so ensuring it’s working properly is very important to the longevity and functionality of your computer.
Option 2: Printer
It is not a compulsory element to be present in a computer for its normal function. Without it also a computer can run smoothly.
Option 3: Gaming consoles
It is not a compulsory element to be present in a computer for its normal function. Without it also a computer can run smoothly.
Option 4: CD/DVD player
It is not a compulsory element to be present in a computer for its normal function. Without it also a computer can run smoothly.
Hence, the correct answer is "Processor".
