Data representation means how we represent any data, here data representation is made up of two words: data + representation, here data means information or in other words fact, data is any information. Can also be in form like audio, video, pictures, gif etc. And how this data should be represented is called representation of the data. All the data in computer means audio, video, pictures, all these are stored in the form of binary. This process happening in computer is called data representation. Data is a raw fact which is of no use in its raw form. But only when we process and interpret the same data, its true meaning comes out, and which is very useful for us. This processed data is also called information. This information is saved in the computer in the form of audio, video, pictures, MP3. Which we call data.
Data measuring unit
Some standards are used to measure how much data can be stored in a computer. Data can be measured in different ways, that is, it is measured according to its capacity and space, for which some units are used like –
Bits
Bit means ‘Binary Digit’, it is the smallest unit of measurement. The value of a bit can be only one binary digit, whether it is 0 or 1. That is, 1 bit = binary digit (0,1), in this way the computer The number of letters you write will take up the space of a beat in the memory. A bit can have only one value. Computer understands the language of binary codes only. These binary codes are called Bit.
Bytes
It consists of 8 bits of memory i.e., 8bit = 1byte, meaning 1byte is made up of 2 nibbles. This is a standard unit of memory. That is, if we store any data, it occupies at least 1 byte of space. Bytes can store 256 states of information. Byte in computer is the next unit from bit, a ‘B’ is always called a byte. And small ‘b’ means bit.
Kilobytes
Kilobyte is made up of 1024 bytes. Kilobytes are often used to measure the size of small files. For example, a plain text document contains 10 KB of data and hence has a file size of around 10 kilobytes. This measurement is often used to describe memory capacity and disk storage.
Megabytes
Here megabytes mean 1024 KB i.e., 1024 kb together makes megabyte, MB has more capacity to store data than KB. Megabyte is often used to measure the size of large files. For example, a high-resolution JPEG image file can be one to five megabytes in size. Uncompressed raw images from a digital camera may require 10 to 50 MB of disk space. A three-minute song saved in a compressed format can be approximately three megabytes in size, whereas the capacity of most other forms of media, such as flash drives and hard drives, is usually measured in gigabytes or terabytes.
Gigabytes
This 1024 megabytes together is 1 gigabyte. The size of GB is larger than that of MB. 1 GB is equal to 1024 MB. It can store large files. If we talk about the capacity of 1 GB then 230 Mp3 Songs can be stored.
Terra byte (TB)
This 1024 gigabytes together form one terabyte. TB full form is Terabyte. Terabyte is bigger than GB. Let me tell you that 1TB is made up of 1024 GB. It has the capacity to store a lot of data.
Petabyte (PB)
This 1024 TB is one Peta byte. PB full form is Petabyte. One Petabyte is equal to 1024 TB and 1000000 GB. This means that one Petabyte is made up of 1024 TB. But let me tell you that till now no device is available in such a large quantity.
Exabyte (EB)
This 1024 PB together is one EXA BYTE. This is a very big storage unit, a huge amount of data can be stored in it or in other words, in 5 Exabyte we can store all the words spoken by the entire human race.
Zettabyte (ZB)
Zetta Byte (ZB) These 1024 EB together form a ZETTA BYTE. 1024 EB = 1 ZB We cannot compare it with anyone because it provides very large storage.
Yettabyte (YB)
This 1024 ZB together is one Yetta Byte. 1024 ZB = 1 YB.
What is information?
Telling or narrating any information to someone, or conveying it to him through any medium is called information. Information is a very important unit, through information about anything we are able to know about it and for better information we can read more about it. We also collect information so that we can have complete information about it. Information is a type of data. Which is made suitable for us to understand and use. Through information we can get information about how to do any work.
