EDVAC refers to Electronic Discrete Variable Automatic Computer which is one of the original electronic computers. All data must be stored in a register before it can be processed. It is sometimes referred to as the microprocessor or processor. The von Neumann architecture refers to one that keeps the data as well as the programmed instructions in read-write RAM (Random Access Memory). Program counter (PC) - holds the memory address of the next instruction to be fetched from main memory. The fetch-decode-execute cycle describes how a processor functions. Current instruction register (CIR) - holds the instruction that is currently being decoded and executed. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on a 1945 description by John von Neumann and others in the First Draft of a Report on the EDVAC. Von Neumann architecture was created in the mid 1940s by John von Neumann, a pioneering computer scientist. Unlike a hard drive (secondary memory), this memory is fast and also directly accessible by the CPU. Suitable for use with AQA, CIE, Edexcel & OCR. The control unit controls the operation of the computer’s ALU, memory and input/output devices, telling them how to respond to the program instructions it has just read and interpreted from the memory unit. Holds the memory location of data that needs to be accessed, Holds data that is being transferred to or from memory, Where intermediate arithmetic and logic results are stored, Contains the address of the next instruction to be executed, Contains the current instruction during processing, Carries the addresses of data (but not the data) between the processor and memory, Carries data between the processor, the memory unit and the input/output devices, Carries control signals/commands from the CPU (and status signals from other devices) in order to control and coordinate all the activities within the computer.
