A computer manipulates data consistent with instructions of a stored program. Stored program means that the data and program are stored in same memory unit. Central processing unit (CPU) performs the bulk of data processing operations. It has 3 main components:
1. A set of registers for keeping binary information.
2. An 'Arithmetic and logic unit' also referred by (ALU) for performing data manipulation
3. A control unit also called as CUwhich controls and coordinates the different operations and initiates appropriate sequence of micro-operations for every task.
Computer instructions are generally stored in consecutive memory locations and are executed in sequence one by one. Control unit permits reading of an instruction from a specific address in memory and executes it with help of Register and ALU.
Parallelism Conditions As discussed earlier, parallel computing needs the segments to be executed in parallel should be independent of each other. So before executing paralleli
