What is Computer Architecture?Ĭomputer architecture is defined as a specification that describes how computer hardware and computer software technologies interact to create a computer platform or system. So, how do you explain computer architecture? It is the rules that a computer system performs and operates. This science determines how a computer works. It’s a set of rules that states how computer software and hardware join together and interact to make a computer work. It seems complicated, but its definition is easier than it sounds.Ĭomputer architecture is a science. When you define computer architecture, it helps to understand what is meant by architecture of computer networks. Read on to answer your questions what is computer architecture and is it an in-demand career? Computer Architecture Definition Computer architects construct balanced and efficient computer and operating systems.īut what exactly is architecture in computer science? If you’re wondering what computer architecture means and want to learn more about a career in this unique field, this article will help. They put their skills to the test to create habitable spaces. should behave.Architecture is more than the act of building. The control unit also dictates how the memory, input output devices, arithmetic logic unit etc. It transfers data throughout the computer as required including from storage unit to central processing unit and vice versa. This unit controls all the other units of the computer system and so is known as its central nervous system. The arithmetic logic unit and the control unit together form the central processing unit. The control unit transfers data from storage unit to arithmetic logic unit when calculations need to be performed. It can perform operations like addition, subtraction, multiplication, division etc. Secondary storage contains a large amount of data permanently.Īll the calculations related to the computer system are performed by the arithmetic logic unit. The data from secondary storage needs to be brought into the primary storage before the CPU can use it. Secondary or external storage is not directly accessible by the CPU. Primary storage is also known as the main memory and is the memory directly accessible by the CPU. It is traditionally divided into primary storage and secondary storage. Storage unit contains many computer components that are used to store data. The different output devices are monitors, printers, speakers, headphones etc. Most of the output data is the form of audio or video. The output unit provides the results of computer process to the users i.e it links the computer with the external environment. are the most commonly used input devices. It takes data from the input devices, converts it into machine language and then loads it into the computer system. So, basically it links the external environment with the computer. The input unit provides data to the computer system from the outside. The control unit controls all the other units as well as their data.ĭetails about all the computer units are − This is because stored data is computed on before being stored again. The data constantly moves from storage unit to ALU and back again. Similarly, the computed data travels from ALU to output unit. The input data travels from input unit to ALU. The different components in the Computer System Architecture are Input Unit, Output Unit, Storage Unit, Arithmetic Logic Unit, Control Unit etc.Ī diagram that shows the flow of data between these units is as follows − It should maximize performance and reduce costs as well as power consumption. A computer system is basically a machine that simplifies complicated tasks.
