Document Summary

Software is the collection of instructions which are stored in memory and executed by the processor (cpu) Instructions must be written in the language of the processor. Machine language is the general term to describe processor language, and it varies by the processor. Software is written in a high level language. High level language means a lot of abstraction. Thus, a hll is one which a human programmer can understand. A collection of lines of a hll is called source code. Source code is passed to a compiler, which translates the source code into machine language, and outputs an object file. An object file is passed to a linker, which brings in an links other dependencies, and outputs an executable file. Software development: specify the problem/goal that needs to be solved, analyze the problem and break it into more basic parts, design a series of steps (algorithm) which can be followed to solve the problem.
