CPU

A central processing unit (CPU) is an important part of every computer. The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body.The CPU is an electronic machine that works on a list of computer things to do, called instructions. It reads the list of instructions and runs (executes) each one in order. A list of instructions that a CPU can run is a computer program.The clock rate, or speed of a CPU's internal parts, is measured in hertz (Hz). Modern processors often run so fast that gigahertz (GHz) is used instead.

RAM

Random Access Memory (or simply RAM) is the memory or information storage in a computer that is used to store running programs and data for the programs.
 
Data (information) in the RAM can be read and written quickly in any order. Normally, the random access memory is in the form of computer chips.
 
Usually, the contents of RAM are accessible faster than other types of information storage but are lost every time the computer is turned off

Hard Drive

A hard disk drive (HDD), hard disk or hard drive, is a data storage device for computers which uses magnetic storage to store data.
 
The capacity of a hard drive is usually measured in gigabytes (GB), however hard disk capacity can also be measured in terabytes when the capacity is over 1000 gigabytes.
 
A gigabyte is one thousand megabytes and a megabyte is one million bytes, which means that a gigabyte is one billion bytes. Some hard drives are so large that their capacity is measured in terabytes, (TB) where one terabyte is a thousand gigabytes (1 TB = 1024 GB).

Video Card

Graphics Card

In computing, a video card (also called a graphics card or a graphics accelerator) is a special circuit board that controls what is shown on a computer monitor and calculates 3D images and graphics.
​
A video card can be used to display a two-dimensional (2D) image like a desktop, or a three-dimensional (3D) image like a computer game. 
 
Computer-Aided Design (CAD) programs are often used by architects, engineers and designers to create 3D models on their computers. If a computer has a very fast video card, the user can create very detailed 3D models.
​
Most computers have a basic video and graphics capabilities built-in to the computer's motherboard. These "integrated" video chips are not as fast as in separate or "discrete" graphics cards.
 
They are fast enough for basic computer use and basic computer games. If a computer user wants faster and more detailed graphics, a video card can be installed.
