What is Data?
Data is an information that has been translated into a form that is efficient for movement or processing. Relative to today’s computers and transmission media, data is information converted into binary digital form. It is acceptable for data to be used as a singular subject or a 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 known as the father of information theory. He ushered in binary digital concepts based on applying two-value Boolean logic to electronic circuits. Binary digit formats underlie the CPUs, semiconductor memories and disk drives, as well as many of the peripheral devices common in computing today. Early computer input for both control and data took the form of punch cards, followed by magnetic tape and the hard disk.
How data is stored?
The data we stored in our computer including video, images, sounds and text, is represented as binary values using patterns of just two numbers: 1 and 0. A bit is the smallest unit of data, and represents just a single value. A byte is eight binary digits long. Storage and memory is measured in megabytes and gigabytes.
Data measurement
1Byte = 1024 Bits
1Kilobyte = 1024 Bytes
1 Megabyte = 1024 Kilobytes
1 Gigabyte = 1024 Megabytes
1 Terabyte = 1024 Gigabytes
1 Petabyte = 1024 Terabytes
1 Exabyte = 1024 Petabytes
1 Zettabyte = 1024 Exabytes
1 Yottabyte = 1024 Zettabytes
According to Wikipedia, there are further units also (Unofficial)
1 BrontoByte = 1024 Yottabytes
1 GeopByte = 1024 Brontobytes
1 GoogolByte = 1024 Geopbytes
1 SaganByte = 1024 Googolbytes
1 PijaByte = 1024 Saganbytes
