Can you guess the key word that is being defined before revealing the answer?

Immediate Access Store. A temporary store for the instructions and data of a program.Main Memory
Volatile part of main memory in which the locations can be accessed directly in any order (i.e. Random Access) for writing and reading data.Random Access Memory
Electronic/electrical circuits that a computer is assembled from. The platform on which the software executes.Hardware
Part of the system bus. Bidirectional. Typically consists of 8 wires used to transport control signals between the three main internal components of a computer.Control Bus
Non volatile part of main memory. Cannot be written to once it has been set up.Read Only Memory
A computer device that is not part of the CPU.Peripheral
Allows the CPU to communicate with peripherals.I/O
A set of parallel wires connecting independent components of a computer system.Computer Bus
The main highway connecting the processor, main memory and Input and Output controllers.System Bus/External Bus
Part of the system bus. Unidirectional. Typically consists of 32 wires. Used to address memory locations and I/O locations.Address Bus
Responsible for executing programs and supervising the function of the other parts of the system.Processor
A separately addressable area of main memory.Memory Location
Part of the system bus. Bi directional. Typically consists of 32 wires to transport data between the three main internal components of a computer.Data Bus
Permanent storage memory not directly connected to the processor. Backing store.Secondary Storage
Electrically erasable programmable read only memory. Contents can be altered but can take 100 times slower to write data compared to reading it.EEPROM
A hardware unit that sends or receives data or stores data by communicating with the processor, main memory and I/O controller.I/O device
