- computers can perform four general operations: input, process, output, and storage. | information processing cycle |
an electronic device, operating under the control of instructions stored in its own memory unit, that can accept data, manipulate the data according to specified rules,produce information from the processing, and store the results for future use | computer |
collection of raw facts, figures, and symbols, such as numbers, words, images, video, and sounds given to a computer during the input operation | data |
is data that is organized, meaningful, and useful. Computers manipulate data create information | information |
detailed set of instructions that tells the computer exactly what to do. The computer executes one program instruction after another until the job is complete | Computer Program (software) |
input devices, the processor (control unit and arithmetic/logic unit), memory, output devices, storage devices, and communications devices | Primary Components of a Computer |
box-like case which houses the processor, memory, and storage devices | System Unit |
any hardware component that allows you to enter data, programs, commands, and user responses into a computer. examples: keyboard, mouse, digital camera scanner, scanner, and microphone. | Input Device |
interprets and carries out the basic instructions that operate a computer. The processor is made up of the control unit and arithmetic/logic unit | Central Processing Unit (processor) |
interprets the instructions | control unit |
performs the logical and arithmetic processes | Arithmetic/Logic Unit |
consists of electronic components that store instructions waiting to be executed by the processor, data needed by those instructions, and the results of processed data. | RAM (memory) |
- is “built-in” computer memory containing data that normally can only be read, not written to | ROM (Read Only Memory) |
- is the main circuit board in the computer to which many electronic components are attached. | Motherboard (system board) |
