Registers
Internal memory
Buses - 3What is a Input deviseAn input device allows data, such as text, images, video or sound, to be entered into a computer system.
- 4What is a Output deviceThere are many outputs created by a computer system. These include printed document, on-screen data,
sound. - 5What is Backing storageThis is where data is stored when it is not being actively used.
- 6What is a address bus and a data busWhen data is saved or loaded from memory, the address at which it is to be stored or loaded from must be
sent. - 7What does the controller do inside the CPUThe controller sends and receives signals from all parts of the computer.
- 8What does the ALU: Arithmetic and logic unit do insied the CPUIt performs simple calculations on the
data that is temporarily stored in the registers. - 9What do Registers do inside the CPUA register is a storage location found on the CPU where data or control information is temporarily stored.
- 10What is the Internal memory inside the CPUInternal memory is fast access temporary storage on the CPU.
Data is moved from the registers to the internal memory when it is not being actively used. - 11What do Busses do in the CPUBuses allow data to be transferred to different parts of the computer.
- 12What are the stepps of the Fetch Decode Execute cycle1. The first instruction is fetched from memory into the control unit.
2. This 2nd instruction is then decoded to determine the action that needs to be carried out.
