Components of Computer

A computer consists of several key components that work in harmony to execute tasks and provide functionality. Let’s delve into the primary components:

Central Processing Unit (CPU)

The Central Processing Unit, or CPU, is often referred to as the brain of the computer. It performs the majority of the processing tasks, executing instructions, performing calculations, and managing data flow. We’ll explore the CPU architecture, types, and factors to consider when choosing a CPU for your needs.


The motherboard is the main circuit board that connects and allows communication between various components of the computer. It houses the CPU, memory modules, storage devices, and other essential peripherals. We’ll discuss the motherboard’s role, form factors, and important considerations when selecting one.
