Bit 1. bit=From a shortening of the words “binary digit” 2. the basic unit of information for computers 3. 1 or 0 are the only values

Byte 1.Byte = 8 bits Each keyboard character is stored as a byte Example -> A =

Terms for Storage Capacities 1 bit = 0 or 1 (b) 8 bits = 1 byte (B) 1 thousand bytes = kilobyte (KB) 1 million bytes = megabyte (MB) 1 billion bytes = gigabyte (GB) 1 trillion = terabyte (TB)

Examples of Data Size Data Size (in bytes)Example 10 Bytes (B)1 world in English Language 2 Kilobytes (KB)1 typed page of English words 3 Megabytes (MB)1 high-resolution photo 2 Gigabyte (GB)20 meters of books on a library shelf 1 Terabyte (TB)50,000 trees made into paper and printed
