Branches of computing
- 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)

Instruction-level taxonomies
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
Software
- Software engineering
- Computer programming
- Computational
- Software patent
- Firmware
- System software
- Application Software
- Programming languages
- Speech recognition
- Speech synthesis
