Binary as Storage p4

ASCII Format

  • ASCII is commonly used to encode information.

  • It includes:

    • Lower-case letters

    • Upper-case letters

    • Numbers (0-9)

    • Common symbols (e.g., &, ^, #, ")

  • Encodes characters in bytes used in modern computers.

Unicode Standard

  • Developed by Unicode Consortium (non-profit).

  • Improves upon ASCII format.

  • Assigns a unique number to every character, regardless of platform or language.

  • Supports a wide range of characters, including emojis (e.g., U+1F600).

Storing Data in Binary

  • Titles converted to binary require significant 0's and 1's.

  • More data requires more bytes.

  • Size conversions:

    • 1024 bytes = 1 kilobyte (KB) = ~180 words

    • 1024 KB = 1 megabyte (MB)

    • 1024 MB = 1 gigabyte (GB)

  • Measurement applies to system memory and data storage.

  • Most memory types are volatile storage (data lost when powered off).
