Data is information in a computer that has been given a form that is capable of movement and processing that is being converted into a binary digital form relative to today’s computers and transmission media. It is acceptable to use as subject or plural subject. Raw data is a term used to describe data in its most basic digital format.
The concept of data in the context of computing has its roots in the work of Claude Shannon, an American mathematician who is known as the father of information theory. He introduced binary digital concepts based on implementing two-valued Boolean logic in electronic circuits. Binary digit format belongs to CPUs, semiconductor memory, and disk drives as well as many peripheral devices common in computing today. Early computer input for both control and data took the form of punch cards, then magnetic tape and hard disks.

Claude Shannon has its origins in the work of an American mathematician who is known as the father of information theory. He introduced binary digital concepts based on implementing two-valued Boolean logic in electronic circuits.
Binary digit format refers to peripheral devices in a simple form in computing today, along with CPUs, semiconductor memory, and disk drives. Early computer input for both control and data took the form of punch cards, followed by magnetic tape and hard disks.
The importance of data in commercial computing in the early stages of the terms “data processing” and “electronic data processing”. Which, for a time, came to encompass the full gamut of what is now known as information technology? The corporate computing, specialization occurred, and with the development of corporate a separate data profession emerged along with the growth of corporate data processing of In the history.
How is data stored?
A hard drive or any other storage device is used to store data or information in the computer. Data that is stored in computer memory/storage, are mainly categorized.
- Permanent Storage (Hard Disk / Hard Drive)
- Temporary Storage (RAM – Random Access memory)
The only difference in this is that permanent storage retains the data in case of power failure; it retains your data until you delete the data yourself.
The same when there is a power failure, the temporary memory data is lost immediately, and that is, it is managed by the computer’s CPU itself.
Temporary memory is used to perform the process in a computer application and when the process is completed, it is used to complete another new process.
It is specially used to store temporary files.
In most contexts, the computer uses the number of bites as a measure, regarding the memory (primary storage) capacity and storage (secondary) capacity of the computer.
Computer memory is partitioned (divided into small parts) into several data containers called memory cells.
All cells can store only a specific amount of data called a keyword and all cells have an associated location identifier called a key address.
To go to the storage of any computer memory, their two aspects are considered, which are – number of bits per cell and the number of cells in which the memory is partitioned.
For example, computer memory depends on how many bites of ham are stored in each cell and how many cells are available. According to the computer world, the sequence of 8-bits (also called a byte), is the basic unit of memory.
Units for measuring memory (Data Storage Capacity)
|1 bit||1 Binary digit|
|8 bit||1 Byte|
|1024 Bytes||1 Kilobyte|
|1024 Kilobyte||1 Megabyte|
|1024 Megabyte||1 Gigabyte|
|1024 Gigabyte||1 Terabyte|
|1024 Terabyte||1 Petabyte|
Types of Data in computer
Now I will tell you a little bit about the data. Then we can say that data type, is a kind of classification. That is to say, it does a kind of division that specifies what kind of value a variable has and what types of mathematical, relational, or logical operations should be applied to them so that no error comes.
For example, the string is a data type that is used to classify text, while an integer is a data type that is used to classify whole numbers.
|Data Type||Where it is use||Example|
|Boolean||To represent Logical Values||True/False|
|character||For encoding the numerically||97(in ASCII97 is a lower case ‘a’)|
|Float (floating point)||Number having a decimal point||9.15 5.03 0.125|
|Integers||Whole||74 124 99009|
|String||Alphanumeric characters||Hello world ram 123|
Let us now talk about the main types of data
Prepares computer numerical data using numbers from 0-9, and it is the most commonly used type of data.
The alphabets of both Hindi (क, ख, ग) and English (a, b, c) come under this alphabetic data.
Symbolic (Alpha Numeric Data)
It is being known that in this, symbols like @, #, $ are used to create data.
This kind of data is created using any song or any other recording which is in mp3 format.
This kind of data is made using any song or any other video recording which is in mp4 format.
Image, picture, graphical data, etc. are used under this type of data. Such as – JPG, PNG format.
