Computer literacy. Computer literacy is defined as the knowledge and ability to use computers and related technology efficiently, with skill levels ranging from elementary use to computer programming and advanced problem solving. Computer literacy can also refer to the comfort level someone has with using computer programs and applications.
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. Programmers typically use high-level programming ...
Computer simulation, one of the main cross-computing methodologies. Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. [ 1] It includes the study and experimentation of algorithmic processes, and the development of both hardware and software. Computing has scientific, engineering, mathematical ...
For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. [2] In the case of an application program or a computer video game , the most relevant layer is the operating system, so it can be called a platform itself (hence the term cross-platform for software that can be ...
Software consists of computer programs that instruct the execution of a computer. [2] Building on previous innovations in mathematics and technology, software was created for the programmable digital computers that emerged in the late 1940s and was necessary to realize their usefulness.
Various EUD approaches exist, and it is an active research topic within the field of computer science and human-computer interaction. Examples include natural language programming, [2] [3] spreadsheets, [4] scripting languages (particularly in an office suite or art application), visual programming, trigger-action programming and programming by ...
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 ...
Software engineering is an engineering approach to software development. [ 1][ 2][ 3] A practitioner, called a software engineer, applies the engineering design process to develop software. The terms programmer and coder overlap software engineer, but they imply only the construction aspect of typical software engineer workload.
