Basics of Computer Science

• Basically there are just some basic/fundamental knowledge that every CS student should just know, as in if you were asked about it anytime/anywhere you could just blurt out the answer.. at least that’s the goal of what I’m hoping to achieve 🙏

Basics

• Basic terminology
• Code compilation process
  • Code Compilation Process in C
  • Code Compilation Process in Java
• Binary numbers
  • A number composed of just 0s and 1s (base-2 number)
  • All information in a computer is stored as binary numbers
  • bit - single binary digit
  • byte - 8 bits
    • kilobytes (KB) = $2^{10}=1024\approx 1000$
    • megabytes (MB) = $2^{20}=1024\text{ KB}$
    • gigabytes (GB) = $2^{30}=1024\text{ MB}$
    • terabyte (TB) = $2^{40}=1024\text{ GB}$
• Types of program errors
• Library VS Framework
• Procedural VS OOP

Language Design Approaches

• Top-down VS Bottom-up (OOP)
• Dynamic typing VS Static Typing
• High level VS Low level
• Compiled VS Interpreted
