Have you ever tried to open your PC and looked into it ?
If no then I will tell you what are the components on which a computer runs and how they looked inside a computer.
CPU/Processor
I think everybody should know about the CPU of a computer, which we also called Central Processing Unit and also the Processor and the brain of the computer. But where it is located ? The answer of the question is that it is located inside the computer case on the motherboard of a computer. Whenever you press a key or start any application the instruction to act on it goes to the CPU.
CPU is a 2 inch ceramic square with a silicon chip located inside.
The CPU fits into the motherboard's CPU socket which is covered by heat sink from which the heat is absorbs from the CPU.
The speed of the processor is measured in MHz (Megahertz) or GHz(Gigahertz). The faster processor can execute more instructions faster. But processor is not the only medium to get speed on the computer. The speed depends on the number of components of the computer.
Motherboard
The power supply unit converts the power came from the main power supply unit of your home or office to the power needed by the computer. It then sends that power through the cables to the
motherboard and the various components of the computer.
Tip: If you are trying to open your computer case then be sure that you unplug the power supply to the computer. Before touching any object inside the computer touch the grounded metal objects to discharge any static buildup.
RAM
RAM which is also known as Random Access Memory is a memory which is volatile memory, means as soon as the power off the data in the RAM will lost. When performing any calculation or logical operations it stores the data temporarily to perform the operations on that data.
RAM measured in terms of MB (Megabytes) or GB (Gigabytes). If you have the more amount of RAM then you can use more applications simultaneously i.e. Multitasking capabilities increases of a computer.
Hard Drive
Hard drive is a place in a computer where you can store data. It is the place of your installed softwares and also where the documents were saved. It is a long term storage memory where data will be saved even after the power off. When you open any document or a software then computer copies small amount of data into the RAM to easily access the data.
Common hard drives are Hard disk, floppy disk, flash drives, disk drives.
Sound and Network Card
The sound card is responsible for what you hear from the speakers or headphones. Motherboards have built in sound card but you can upgrade it to enhance the sound quality.
The network card allows you to communicate over a network and access the internet. Almost all the motherboard have the built in network card and also has a expansion slot to add another upgraded card.
This guide can be helpful for beginner computer users. Hopefully they understood the simple basic internal interface of a computer.

Motherboard
It is the main circuit board of the computer. It is a thin plate that holds the CPU, external USB ports, memory, connectors, hard drive optical drive etc. The motherboard actually connects every parts of the computer either directly or indirectly.
Power Supply Unit
The power supply unit converts the power came from the main power supply unit of your home or office to the power needed by the computer. It then sends that power through the cables to the
motherboard and the various components of the computer.
