What is a microprocessor?

A microprocessor is simply a computer processor that has been configured in the design and function of a microchip. Sometimes called a logic chip, this small component serves as the means of executing the command to boot the computer. As part of the process, the microprocessor initiates the activation of all components necessary to allow the computer to be used, such as waking up the operating system.

The microprocessor in a computer activates the operating system and performs the calculations that keep it running.

The basic functionality of this processor is all based on its inherent ability to respond and generate mathematical and logical operations. This is possible with the use of registers, in which all the data necessary to perform basic functions such as addition and subtraction reside. Configuring the registers also allows the microprocessor to perform tasks such as comparing two different numbers and retrieving numbers from various areas and redistributing them.

At the heart of the design is a series of logical instructions that regulate the order in which tasks are received and performed. The presence of instructions ensures that tasks are performed in a sequence that will flow from the completion of one task to the logical start of the next task in the sequence. For example, when an end user boots up a computer, the first instruction to be executed is to activate the BIOS or basic input/output system. From that point, the BIOS will load the operating system into active memory and proceed to the next task in the boot process. Each successive task will be reached as soon as the previous task is completed.

Generally, a microprocessor is a component that remains efficient and productive for the life of the computer. It is possible for the chip’s functionality to be damaged in some way, however, and when that happens, it’s usually an easy process for a computer technician to replace the corrupted chip with a fully functional one.
