Graphics card :

It is responsible for analyzing files, images and data and is then displayed on the screen.

Graphics Card Date:

The first video card was made in 1960 and the first video card was produced by IBM (the company that does not currently use it) in 1981 and was known as (MDA) short for Monochrome Display Adapter and its memory is only 4 KB and supports only one color.

Display Resolution:

All that is displayed on the computer screen is composed of points called (Pixel) The more points in the screen the more accurate the image displayed on the screen.


 for example:


    1080p----> 2,073,600 points.
    720p---->921,600 dots.
     480i----> 307,200 dots.

Calculates the number of points by multiplying the length in width.

Example:

 1080p (1080)x(1920)=2,073,600pixels

Graphics Card Types:

1. Built-in and be in the motherboard.
2. Dedicated graphics card.

What is the difference between a built-in and a separate monitor?

Built-in graphics card:

1. Small size and be in the laptop.
2. He takes his speed at the width of the ram.
3. It cannot be changed.
4. If the card is damaged, the motherboard will be damaged.

Discrete Graphics:

1. Its size is large and therefore stronger.
2. He has his own speed.
3. You can change it whenever you want.
4. If it crashes replace it alone without other pieces.

Graphics Card Components:

1. portal.
2. card processor.
3. memory.

What is the screen refresh rate?

 

Is the screen refresh rate of the image displayed per second,
For example, when you hear 60 Hertz you know what 60 images are meant per second.
The higher the number of images per second, the smoother the picture.

What should you consider before buying a graphics card?

1. Graphics Card Size.
2. Video card ports.
3. The speed of the screen card.
4. The speed of the graphics card processor.
5. Its compatibility with the motherboard.
6. Hertz.
