Understanding What is Inside Your Computer and How it Works

Have you ever looked inside a computer case? Its small parts may look complex, but it is not really mysterious inside the computer case. Here you will understand a little bit more about some basic parts

Motherboard:-

The motherboard is the main circuit board of the computer. It is a thin plate with connectors for CPU, memory, hard drives and optical drives, expansion cards to control video and audio, and connections to your computer's port (such as USB ports). The motherboard connects directly or indirectly to each of the computer's components.

Processor:-

The Central Processing Unit (CPU), also known as the processor, is located on the motherboard in the case of a computer. This is called the brain of the computer. It produces the output by processing the input information.

The CPU is usually two inches of Ceramic Square with a silicon chip. This chip fits into the motherboard's CPU socket, which is covered by a hit sink, which soaks up heat from the CPU.

As you might think, CPU speed and performance is the most important factor that determines how a computer will work.

Processor speed is measured in Megahertz (MHz) or Gigahertz (GHz). Faster processors can execute instruction faster.

RAM:-

RAM is the short-term memory of your system. All the processes running on the computer are temporally stored in RAM.

The more capacity RAM the computer has, the more applications you can work on simultaneously.

This short-term memory disappears when the computer is turned off. If you are working on a Word, spreadsheet, or other type of file, you have to save it to avoid losing it. When you save a file, this data is stored on the hard drive, which acts as a permanent storage.

Speeds of RAM are in Megabytes (MB) or Gigabytes (GB). The more RAM you have, the more things computers can do at the same time.

HDD:-

Hard drives are permanent storage of data. All the data on your computer is stored on it.

IDE hard drives, SATA hard drives and SCSI hard drives are the main types of hard disk or HDD.

Today, hard disks in personal computers have 80GB, 120GB, 160GB, 250GB, 320GB, 500GB, 1TB and 2TB capacities.

Optical Disk:-

Most desktop and notebook computers come with optical drives, which are either a CD / DVD or Blu-ray disc.

SMPS:-

Switched-Mode Power Supply (SMPS) takes AC input from the wall outlet, performs power factor correction and then converts the output to a low voltage DC output. It sends power via cable to the motherboard and other components.
