Introduction To Bytes
In the world of computers, all the bytes are used to describe disk space, data storage space, or system memory. A few years ago, we were describing hard drive space using the term megabytes (millions of bytes)
Diskettes and Floppy disks were described using Kilobyte.
Today, Gigabytes are the commonest term used to describe the size of drives, including flash, CD, DVD, and Hard drives.
In a couple of years to come, we shall be hearing Terabytes (trillions of bytes of information space) though modern systems now come inTerabytes.
Data storage starting from the smallest unit are: bit, byte, Kilobyte (Kb), Megabyte (Mb), Gigabyte (Gb), Terabyte (Tb), Petabyte (Pb), Exabyte and Zettabyte.
