Block Diagram of Computer|| Basic Explanation

A typical computer system irrespective of its size, class or type consists of hardware and software, integrated and synchronized together to perform computational work or data processing. Computer anatomy is concerned with the way the various functional units operate and how they connected together to form the computer system.
A computer system consists of the following functional units :
1) Input unit
2) Memory/Storage unit
3) CPU(central processing unit)
4) Output unit

Components of Computer System

A system is defined as a set of interacting elements, responding to inputs so as to produce outputs. The computer system also consists of the following elements or components. Software Hardware Firmware Humanware Software All the intangible components of the computer system are known as software In other words, we can say that all computer programs and applications run behind the monitor screen, are known as software. Computer software is a term that describes computer programs. Example Microsoft-windows (all operating system software) and notepad, MS office suite, window media player(application software). Software is further divided into two parts these are following 1) system software 2) application software Hardware All tangible component of a computer system is known as hardware. In other words, computer hardware is the collection of physical parts of the computer system. Example CPU(Microprocessor), monitor, keyboard,...

Types Of Computer System || Analog Hybrid and Digital Computer System

Types of computer There are various methods on which computers can be classified. The classification may depend upon the size, technology, area, of application, type of data processed, etc. Generally, computers are divided into three main parts, These three are followings: Analog computers Hybrid computers Digital computers Analog computers An analog computer or analogous computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical , mechanical , or hydraulic quantities to model the problem being solved. Analog computers are computers that work on continuous data. Analog computers are used to measure physical quantities like pressure, temperature, speed, etc. Analog computers were widely used in scientific and industrial applications where digital computers of the time lacked sufficient performance. Analog computers c...
