Historically, parallel computing has been considered to be the high end of computing, and has been used to model difficult problems in many areas of science and engineering. Dataflow architectures do not have a program counter in concept. Block diagram of computer and explain its various components.

An instruction set architecture isa is the interface between the computers software and hardware and also can be viewed as the programmers view of the machine. The most prominent items within the cpu are the registers. Harvard any computer architecture that stores instructions in one memory system and data. Explain the role of integrated circuits in design of computers.

Explain how this architecture is similar to different from cloud computing. Some definitions of architecture define it as describing the capabilities and programming model of a computer but not a particular implementation. Arm7 and pentium also refer difference between risc and cisc, risc vs cisc. These three components are connected together using the system bus. The cpu fetches an instruction from the memory at a time and executes it. Also, explain the classification of computer on the basis of technology. In computer engineering, computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. The architecture comprises an alu arithmetic logic unit, a single shared memory for programs and data, a single memory bus. Usually two types of architectures are used in microcontrollers see figure 1. Aug 20, 2018 last date of submission ignou bcs11 solved assignment 201920. A computer built with this architecture would be much easier to reprogram. Computer architecture is the combination of software and hardware that is organized in such a fashion as to deliver the machines intended performance characteristics. The central processing unit can also be defined as an electric circuit.

Briefly explain the basic architecture of a computer. Atmosphere, earth, environment physics applied, nuclear, particle, condensed matter. It will have single set of addressdata buses between cpu and memory. Computer architecture has undergone incredible changes in the past 20 years, from the number of circuits that can be integrated onto silicon wafers to the degree of sophistication with which different algorithms can be mapped directly to a computers hardware. This book is about the brain being viewed as a computing machine. Bcs011solved assignment free ignou computer basics and pc. Hardware is the physical components of a computer and software is the programs that run on a computer. A computers machine language is a reflection of its architecture, with its assembly language adding a thin layer of abstraction for the. This model includes fundamental things like the computers cpu, registry, memory, storage, logic unit and inputoutput io interface. Most computers architecture can be divided into three categories. However, due to its limiting bandwidth operation and underutilization of the processor meant it had to be modified to cater for this.
