- 1The ProcessorDevice that carries out computation by following instructions, in order to produce an output
- 2Main MemoryStores data and instructions that will be used by a processor
- 3Fetch-execute cycleThe continuous process carried out by the processor when running programs
- 4Random Access Memory (RAM)Stores data and can be read to and written from
- 5ChipElectronic component contained within a thin slice of silicon
- 6Read Only Memory (ROM)Stores data and can be read from but not written to
- 7BusMicroscopic parallel wires that transmit data between internal components
- 8Data busTransfers data to and from the processor and memory
- 9Input/Output (I/O) controllerControls the flow of information between the processor and the input and output devices
- 10Word lengthThe number of bits that can be addressed, transferred or manipulated as one unit
- 11Address busUsed to specify a physical address in memory, so that the data bus can access it
- 12Addressable memoryThe concept that data and instructions are stored in memory using addresses
- 13Control busControls flow of data between the processor and other parts of the computer
- 14Von Neumann architectureTechnique for building a processor where data and instructions are stored in the same memory and accessed via buses
- 15Harvard ArchitectureTechnique for building a processor that uses separate buses and memory for data and instructions
