What I Learned in CompSci #5: Data Compression and Encryption

Data Compression and Encryption


What is Data Compression?
WinRAR

Data Compression is storing data that requires less space than usual.

Example of Compressed Data:
  • .zip
  • .rar
You can compress data using WinRar, 7Zip, or any other similar software
From 36kb to 1kb

What is Encryption?
Encryption
Encryption is the process of encoding messages or information in such a way that only authorized parties can read it(1). It enables a person to secure a file by creating a password

2 Main Types of Encryption:
  • Symmetrical - harder, created by the computer
  • Asymmetrical - easier, can be created manually
