Byte (reads bait ) is digital information unit equivalent to eight bits. The byte symbol is an uppercase (B), to differentiate it from bit (b). The byte is used in general in the areas of computing and telecommunications, and in the latter it is commonly called an octet.
The term "byte" is often used to specify quantity, for example, the amount of memory on a particular device or storage capacity. Example: 16 GB (gigabyte)
Each byte represents a single character of text on a computer. The byte represents letters, symbols, numbers, punctuation marks, special characters, etc. and encodes various information in a machine.
Character encoding called ASCII (American Standard Code for Information Interchange) adopted the information that 1 byte is equivalent to 8 bits, and using the binary base (values 0 or 1), defined 256 characters for text representation on computers, thus standardizing operations between different devices.
To express amounts of data, the following measures are used:
1 byte = 8 bits
1 kilobyte (KB or Kbytes) = 1024 bytes
1 megabyte (MB or Mbytes) = 1024 kilobytes
1 gigabyte (GB or Gbytes) = 1024 megabytes
1 terabyte (TB or Tbytes) = 1024 gigabytes
1 petabyte (PB or Pbytes) = 1024 terabytes
1 exabyte (EB or Ebytes) = 1024 petabytes
1 zettabyte (ZB or Zbytes) = 1024 exabytes
1 yottabyte (YB or Ybytes) = 1024 zettabytes
