What is Data ?

What is data? if you use a computer then you must have heard the word "Data". Data is an important part of the computer on which all work is done. Data is input and output into the computer. The CPU's job is to process the data. This post is an attempt to know what is computer data, data processing and type of data in this post.

The career record of any player, number of children in school, population of India, name of someone, all these are called Terms Data. Data is managed, controlled and processed in a computer.

What is computer data or information?

Data is also called Information or simply say that Information is "Data". Input Processed Data is called Information. Information is important for the user.

For example, a news anchor reads "news". This news is information for us. Whereas it is Processed Data for News Anchor. The information is ready by collecting raw data and processing it. You can also understand data or information in this way - as if you are reading our post "What is Data", then this post is information for you. We have prepared this information for you by processing the data.

Image, video, audio, text, number, document, etc. present in the computer are called data. Data is typed from the keyboard. Alphabets from A to Z, number 0 to 9, special character $, @, & all these data. Data is a collection of disorganized facts and data which is only one value. Collecting data is also important. The data is converted into a soft copy after being input into the computer.

Data information. what is data?

It is raw before inputting data into the computer. Data is processed by inputting this Raw Data into the computer. Processed data is called information. Data is stored in a binary digit 0,1 in a computer. These binary digits are called "bits". It is the machine language that the computer understands. Converting data into binary form is called Data Representation.

Harddisks are used to store data in a computer. Apart from this, pen drives also use memory cards for storing data. Computer stores data in two ways. One is the Permanent Store in which data is stored on a hard disk or a pan drive. Another is Temporary Store in which data is stored in RAM. Data is stored in the computer as files. These files are in folders.

Types Of Data

1. Alphabets - A to Z in English and A to Z in Hindi. All these are called Text data. The keyboard has all these Alphabets.

2. Number - This type of data consists of digits from 0 to 9. All these digits are present on the keyboard. Process this data by applying mathematical formulas to it.

3. Alpha Numeric - The keyboard contains alpha numeric data like @, $, &.

4. Image - Format image data like JPEG, JPG, PNG are called.

5. Audio Data (Audio) and Video Data (Video) - This type of data contains sound. Music files come. Formats like MP3, MP4, HD etc. come in this type of data.

If you type a name like Ram, Suresh, Pooja etc., then it also falls under the category of data.

What is Data Processing -

Converting raw data into information by processing it through CPU is called data processing. Input data in a computer is called "Raw Data". The output data is called Information. It has three actions -

A. Input Data, B. Data Processing, C. Output Data

A. In the input process, data is input into the computer. As you type alphabets from the keyboard and input them -

The first step to input data is “Data Collection”. In this, data is collected from various sources. Collected data is verified before inputting. This indicates that the data is right or wrong. On inputting the data, it enters the computer in binary codes (0,1). This allows the computer to read the data. Now the data is stored in the memory of the computer.

B. Data Processing This is the most important step, with this step, data is converted into useful information. In the computer, this work is done by the CPU. Some actions that take place in Data Processing -

The first task is to classify the data. Data is divided into groups. This makes data even easier to understand. Sort the data after this - mainly "Ascending or Descending". After this, do the work of calculating data. If there is a need to apply a formula to the data, then there is a calculation. The final step in processing is data summarization.

C. Output Data - In this process, the data is output as information. The data received after processing is called Information. Output can also be stored in a hard disk. You can read back the information stored.
