1. Reducing the size of a file by sacrificing a portion of its data, leading to a smaller size yet reduced quality.

2. Also known as the Masonic Cipher, it is a substitution cipher used in cryptography that replaces letters with symbols and shapes.

3. Sound represented in a binary format consisting of discrete samples taken at regular intervals.

4. Basic components of digital circuits that perform logical operations

5. A substitution cipher in which the symbol used to replace a letter varies depending on its position in the plaintext.

6. The process of adding two binary numbers to obtain their sum.

7. A unit of data transfer rate equal to one million bits per second.

8. A technique used in cryptanalysis to analyze the frequency of letters or symbols in a ciphertext

9. The way in which a number is expressed.

10. A type of substitution cipher in which each letter in the plaintext is shifted a certain number of places down the alphabet.
