✅ VLC

Variable Length Code

  • code in which every symbol(word) has a different length in binary
  • there are always special rules and special characters to seperate the letters and to seperate words

A ➡️ 01
H ➡️ 0000
U ➡️ 001
  • 👎🏻 More difficult to figure out the portions of the message as each symbol has different legnth
  • 🛠️ used in war environments
  • 🛠️ morse code

✅ FLC

Fixed Length Code

  • code in which all symbols have the same length
  • the number after FLC means the length of every symbol
  • FLC-4: is code is FLC, and each symbol has length of 4

❓ If I got 010111001101(12bits) and it is FLC-4
A: it would be 0101/1100/1101
  • 👍🏻 Easy to break the message into portions
  • 👍🏻 much less accidents in FLC
  • 🛠️ used for commercial or standard purposes
  • 🛠️ SHA-256, SHA-512
  • SHA-512 is stronger as each symbol would have longer length
