Outline of computing
The following outline is provided as an overview of and topical guide to computing:
Computing – activity of using and improving computer hardware and computer software.
Branches of computing[edit]
- Computer science (see also Outline of computer science)
- Information technology – refers to the application (esp in businesses and other organisations) of computer science, that is, its use by mankind (see also Outline of information technology)
- Information systems – refers to the study of the application of IT to business processes
- Computer engineering (see also Outline of computer engineering)
- Software engineering (see also Outline of software engineering)

Instruction-level taxonomies[edit]
After the commoditization of memory, attention turned to optimizing CPU performance at the instruction level. Various methods of speeding up the fetch-execute cycle include:
- designing instruction set architectures with simpler, faster instructions: RISC as opposed to CISC
- Superscalar instruction execution
- VLIW architectures, which make parallelism explicit
