Can you guess the definition before revealing the answer?

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