  1. Bit and Byte

  2. A bit is the smallest unit of information that can be stored or manipulated on a computer • We can also call a bit a binary digit, especially when working with the 0 or 1 values • Depending on meaning, implication, or even style, it could instead be described as false/true, off/on, no/yes, and so on

  3. A byte also happens to be how many bits are needed to represent letters of the alphabet and other characters • the letter "A" would be 01000001 •  "KJW" would be 010010110100101001010111 • Each byte makes by 8 bits

  4. Notice that {A,B,C,D,E,F} are not letters, they are numbers! Hexadecimal "C" means decimal "12" just like binary "1100"

  5. TheAmerican Standard Code for Information Interchange (ASCII)

  6. Bit • A bit is a value of either a 1 or 0 (on or off). • Nibble • A Nibble is 4 bits. • Byte • A Byte is 8 bits. • Kilobyte (KB) • A Kilobyte is 1,024 bytes. • Megabyte (MB) • A Megabyte is 1,048,576 bytes or 1,024 Kilobytes • 873 pages of plaintext (1,200 characters) • 4 books (200 pages or 240,000 characters) • Gigabyte (GB) • A Gigabyte is 1,073,741,824 (230) bytes. 1,024 Megabytes, or 1,048,576 Kilobytes.
