Computer Science: CPU, Memory, Compilation, and Software Development

CPU

The central processing unit of the computer.

RAM

Primary Storage (RAM) is volatile secondary storage.

Compiler

Checks for syntax errors and creates the object file by converting high level language into machine code.

Linker

checks for linker errors and creates the

executable file by combining the source object

file with library object file

Loader

Loads the executable file into main

memory and runs the program

Algorithm

Step by step problem solving process

Software Development Life Cycle (SDLC)

planning, analysis, design, implementation, Testing, maintenance

Structured Design

Breaking a problem into sub problems or pieces

Object-Oriented Design

identify components called objects and determine how objects interact with each other

Errors

Syntax, Linker, Runtime, Logic

semantic rules

Meaning of statements in code

Syntax Rules

The grammar of a programming language
