1. System Architecture

   • Memory
   • Central Processing Unit
     • Registers
     • Buses
   • Storage

2. Algorithms

3. Definitions

   • Iteration
     • When a task is repeated until there is a required outcome
   • Algorithms
     • Step-by-step procedure for solving problems
   • Variable
     • A container Which is used to store value. A named memory location used to temporarily store data that can change during the execution/running of a program. A named value that can change in a program that can affect the outcome.
   • Psudocode
     • Structured English for describing algorithms. It is generic, code-like language that can be easily translated into any programing language
   • Constant
     • Values that We refer to by name but do not change. Python does not provide a Way to create constants. They use variables.
