The part of the computer that performs the bulk of data processing operations is called the central processing unit (cpu) and is the central component of a digital computer.
Cao Unit 3 Pdf Input Output Computer Data Storage The below figure shows a portion computer memory partitioned into three segments: program, data, and stack. the program counter pc points at the address of the next instruction in program. the address register ar points at an array of data. the stack pointer sp points at the top of the stack. Ram or random access memory is the central storage unit in a computer system. it is the place in a computer where the operating system, application programs and the data in current use are kept temporarily so that they can be accessed by the computer’s processor. The part of the computer that performs the bulk of data processing operation is called central processing unit (cpu) which consists of alu, control unit and register array. Both external and internal interrupts are initiated by the computer hardware. software interrupts are initiated by texecuting an instruction. an interrupt procedure usually stores all the information necessary to define the state of cpu rather than storing only the pc. some instructions that performs a certain tasks are not used frequently.

All the functions of the cpu are stored in a component called the chip. the cpu of pc’s are generally implemented on a single chip, called a microprocessor. most of the devices connected to the computer communicate with the cpu in order to carry out a task. The biu handles transfer of data and address between the processor and memory i o devices by computing address (physical effective address) and send the computed address to memory i o and fetches instruction codes then stores them in fifo register set called queue register. Primary storage or main memory (ram) stores data and program statements for the cpu. it has four basic purposes; to store data that have been input until they are transferred to the arithmetic logic unit for processing. to store data and results during intermediate stages of processing. Intermediate data are needed to be stored like pointers, counters, return address, temp results, and partial products. cannot save them in main memory because their access is time consuming.
