| Application programs | Programs that people use to get their work done. |
| Central Processing Unit (CPU) | A particular computer will have a particular type of processor. |
| Computer system | Consists of hardware (physical parts of the computer) and software (programs and data used with the physical computer). |
| Embedded system | A computer system that is part of a larger machine and which controls how that machine operates. |
| Input devices | Keyboards, mouse, scanners, cameras, joysticks, and microphones; a piece of equipment used to provide data and control signals to an information processing system. |
| Main memory | Closely connected to the processor, stored data are quickly and easily changed, holds the programs and data that the processor is actively working with. |
| Motherboard | Components are connected to the main circuit board of the computer. |
| Network | Consists of two or more computers connected so that they can exchange data and programs. |
| Operating system | Responsible for starting up application programs, running them, and managing the resources that they need. |
| Output device | Monitor, printer, speakers; any piece of computer hardware equipment which converts information into human-readable form. |
| Processor | Contains billions of transistors; responsible for the fundamental computing within the system, and directly or indirectly controls all the other components. |
| RAM (Random Access Memory) | Memory cells that can be accessed in any order. The type of silicon chip used to implement main memory. |
| ROM (Read Only Memory) | Used to make a section of main memory read-only. |
| Secondary memory | Connected to main memory, stored data are easily changed, but changes are slow compared to main memory, and used for long-term storage of programs and data. |
