As companies and individuals generate vast amounts of data, I started seeing different units. Kilobytes (KB), megabytes (MB), gigabytes (GB). Various prefixes are added to the unit "byte" to indicate the amount of data. Terabyte (TB), which has become especially familiar in recent years, can be said to be one of the words that represent the age of big data.
In 2007, Hitachi Global Storage Technologies (now HGST) released an HDD with a capacity of 1TB, which was unusual for the time. The evolution of storage is remarkable, such as TB-scale capacity is now commonplace regardless of whether it is HDD or SSD. On the other hand, when asked, "How big is 1TB really?" A quick way to understand TB is to compare it with other units.

Who invented "byte" in the first place
Most computers Normally, 1 byte is 8 bits. Bit is an abbreviation for Binary Digit. The smallest unit of data in a computer that has a binary value of 0 or 1. A memory normally stores a value by storing a predetermined amount of electric charge corresponding to 1 or 0 (amount of electricity carried by an object) in one memory cell (data recording element).
Fred Brooks (Note 1), founder of the Computer Science Department at the University of North Carolina at Chapel Hill, explained that the late Werner Buchholz invented the word "byte" when he was at IBM. do. According to Brooks, Buchholz came up with the byte in 1956 while working on the design of the IBM 7030, said to be the origin of the supercomputer. The IBM 7030 was IBM's first computer built using transistors.

Let's go back to TB. 1TB equals 1024GB. 1GB is 1024MB, 1MB is 1024KB, and 1KB is 1024 bytes. In other words, 1 TB is 1,099,511,627,776 bytes, which equals 1,073,741,824 KB and 1,048,576 MB.
The maximum unit of capacity for memory and storage currently on the market is TB. Units larger than TB include petabytes (PB), exabytes (EB), zettabytes (ZB), yottabytes (YB), and brontbytes (BB). It's only a matter of time before PB-scale storage devices appear.
