Ever wondered what the heck is inside your PC? How can this square block of metal perform enormous amount of computation in a blink of an eye? How can it let you play games that require powerful graphical processing capabilities along with superb calculation and artificial intelligence? You don’t need to study computer science or get a degree that has something to do with computers to understand them. They are pretty straightforward but learning them can be a great asset especially if you are encountering problems with your PC. By knowing the basic parts of your PC and understanding how they work, you’ll be able to appreciate the wonders of computers and hopefully, help you in times of need.

PC guts

CPU (Central Processing Unit)

The CPU or central processing unit, (also called as processor) is often called as the brain of the computer. Its job is to carry commands. When you move your mouse or press a key, you’re sending instructions to the CPU. A processor’s speed is measured in megahertz (Mhz), or millions of instructions for every second, and gigahertz (Ghz), or billions of instructions for every second. A faster processor can execute instructions more rapidly. Nonetheless, the real speed of the computer relies on upon the speed of numerous distinctive components—not only the processor.

Motherboard

The motherboard is where the CPU and other components of the computer connect. It’s the main circuit board, a thin plate that holds the CPU, memory and cables to the hard drive, expansion cards, DVD drive, USB ports and more.

Power Supply Unit

The power supply unit in a computer changes over the force from the wall outlet to the kind of power required by the computer. It sends power through the links to the motherboard and different components.

RAM (Random Access Memory)

This is your computer’s short term memory. Whenever your computer performs calculations, it temporarily stores the data into the RAM until it is needed. The more RAM you have, the more things your computer can do at the same time. If you’re a gamer or developer, 8GB of RAM is perfect for you to ensure a smooth game play and working experience.

Hard drive

This is where data are permanently kept. This is where all of your games, software and OS are installed. This is also where your files are located. Unlike the RAM, where all data is lost when you turn off or unplug the PC, the hard drive will store all of your data indefinitely.

Video Card

This is the one responsible for processing video and computer graphics. They also have their own memory and speed. Basically, the bigger the memory and the faster the speed it has, the faster your computer will be when processing graphics intensive applications like games and 3D rendering.

Other Expansion Cards

The sound card, network card and Bluetooth cards are all optional as they come integrated into most motherboards. FYI, video cards are integrated too, but if you want better and higher quality performance, you might want to consider buying expansion cards.
