## Computerized Data Representation Methods

Data remains stored in the computers by; Computers work on electric power. And therefore we treat them like any electrical device, which receives electrical signals to translate them into a language through which they can manage all its components. The language in which the computer deals is quite different from the human language. Where the computer converts the electrical signals expressed by the difference of voltage into a system that translates this difference in voltage into symbols known as a binary system.

The binary system remains defined as a two-digit (0,1) digital system; each box is called a bit, used in computers as a way to store data and translate commands. This system depends on the presence of base two and raises it to a specific force. And then gives it the required weight to determine the number in the binary system. the following example represents the number (1) and how it remains displayed in the binary system, as follows 0^2 =1, i.e., if we define the number of 8 boxes, which remains known in computer science as “byte,” the number

## How Words remain Represented

Words remain made up of characters. And characters are the basis of our human language, so how does the computer understand them? The computer, as we said, does not understand the symbols and characters that humans understand. So it depends on the existence of a system called ASCII (American Standard Code for Information Interchange). A system that places each character a16-bit hexadecimal number, and then converts it into a binary system so that the character remains treated as a number in the binary system within the computer.

## How to Represent Sound

Audio files remain represented as an Analog software signal and then converted into digital data using the audio coding format. And maybe compressed to reduce the size of the file and the number of bits represented.

## How to Represent the Image

Images remain represented in the computer by small squares (pixels), as a matrix, the number of lines in them and the number of columns determines the accuracy of this image. For example, the idea of 256×256 means that the resolution of this image is 65,536 pixels. And the amount of each pixel determines the amount of intensity of lighting.

## How to Represent Data

The video remains defined as a set of images. It moves at a specific frequency and remains compressed to reduce the file size. And the number of pixels represented, which is called “video compression”.  A process that depends on the presence of certain helmets and has specific strategies based on the type of pressure “compression.”

## How Data remain Signified

The software in the computer is a set of commands that arise in a particular format to implement a specific function. According to the language programmed in it. There are different programming languages, each with orders that work specific ocular processes and deal with a particular type of data; for example, charges deal with characters or sentences.

Some deal with the correct numbers or natural numbers or the truth and so on. Each compiler-translated programming language translates these commands into a dual system that the computer can understand, the so-called “opcode”. The system used to represent data in the computer the system used in computer is the binary system. Each data type for different kinds eventually translates into the binary system whose previously explained mechanism.

Electrical signals remain expressed by voltage difference where the voltage difference is converted from 5 volts and more to 1 while less than 5 volts to 0 in the binary system. Data of all kinds, such as sound, image, video, or written text, remains ultimately treated by the computer as a difference in electrical effort. And represented in a way that makes it easier for people specialized in this field to understand, express. And draw conclusions from them.
