Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Programming language – formal constructed language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.
A kernel connects the application software to the hardware of a computer. The kernel's main purpose is to manage the limited resources of a computer: The kernel program should perform process scheduling, [132] which is also known as a context switch. The kernel creates a process control block when a computer program is selected for execution.
Software development entails the establishment of a systems development life cycle of a software product. It encompasses a planned and structured process from the conception of the desired software to its final manifestation, [4] which constitutes computer programming, the process of writing and maintaining the source code.
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
mychillo The following outline is provided as an overview of and topical guide to software development: . Software development – development of a software product, which entails computer programming (process of writing and maintaining the source code), and encompasses a planned and structured process from the conception of the desired software to its final manifestation.

Systems programming, or system programming, is the activity of programming [1] computer system software.The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor), whereas systems programming aims to produce software and ...
The Preparation of Programs for an Electronic Digital Computer [1] (sometimes called WWG, after its authors' initials) [2] was the first book on computer programming. [3] Published in 1951, it was written by Maurice Wilkes , David Wheeler , and Stanley Gill of Cambridge University .
