A typical digital computer system has four basic functional elements: (1) input-output equipment, (2) main memory, (3) control unit, and (4) arithmetic-logic unit. This unit contains devices with the help of which we enter data into the computer. Control unit manages all the stages using control signals. The architectural design of a computer system is concerned with the specifications of the various functional modules, such as processors and memories, and structuring them together into a computer system. Input Unit. Input Unit. An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. These units are as follows: Input unit Central Processing unit Output unit these units are interconnected by electrical cables to permit communication between them. Four basic network topologies. Input devices are used to interact with a computer system or used enter data and instructions to the computer. Each functional unit performs a dedicated task. Two basic types of computer architecture are: von Neumann architecture; Harvard architecture; 1. von Neumann architecture. Central Processing Unit. The computer is organized into four units as shown in the following diagram. 1 . A block diagram of the basic computer organization has the following functional units. Data and instructions must enter the computer system before any computation can be performed on the supplied data. The main function of input devices is to direct commands and data into computers. Concept of Static block ,Static Variable and Static methods. The input devices translate the information into a form understandable by the computer. This allows the computer to function as a system. All the units also referred to as "The functional units”. Depending on the operation specified by the instruction, operands in the registers are transferred to one of the units, associated with the operands. Above figure shows the block diagram of a computer. ALU. ALU: Arithmetic & Logical Unit MU: Memory Unit . The ALU consists of accumulator, flag register and temporary register. These are The Central Processing Unit (CPU) is divided into two parts again: arithmetic logic unit (ALU) and the control unit (CU). 1 . It performs following tasks: It performs all operations.
