online. A byte is a unit of digital information that consists of eight bits (b). Bits (b) are even smaller than bytes, but a byte is as small as you need to go for most tech users. A file comprises so many bytes–the more bytes, the bigger the file. 1 byte (B) = 8 bits ...
Data unit conversion is very simple when using bytes, as you simply add/remove a specific number of zeros to get the correct value. While a byte is very tiny, a kilobyte equals 1000 bytes, and a megabyte (1 MB) is the same as 1,000,000 bytes (or 8,000,000 bits). A gigabyte (...
