represent ___________-
2. Q represent the CPU which consist of
Explanation:
Computer Architecture is the organization of the components which make up a computer system and describes the functionality, organization and implementations of computer systems. A computer system mainly consists of input unit, processing unit, memory unit and output unit. The input unit in a computer system can consist of keyboard , mouse, etc. Processing unit in the computer system is called the CPU (Central Processing Unit). CPU consists of ALU (Arithmetic and Logical Unit) and CU (Control Unit). ALU (Arithmetic and Logical Unit) performs all the arithmetic and logical operations on the operands. Memory unit us called the Random Access Memory or main memory or primary memory. The output unit consists of screen, printer, etc.
