In other words, you can say that software is the programs that are stored & run by hardware. They are also called intangible components as we canвЂ™t feel, touch or see them because they donвЂ™t physically exist. All these programs or computer applications run behind your monitorвЂ™s screen. Software is a set of instructions or programs and each of these programs is specified to perform a specific operation.

Functions of Operating System & Its EvolutionД¬omputers canвЂ™t think on their own so, they need instructions which instruct them what to do and how to do it.The various elements of the computer system are: Components of Computer SystemДЄ word processor is consists of hardware & software parts. Personal computer, PC, minicomputer, microcomputer, mainframe, data processor, calculator, electronic brain, word processor, workstation, laptop computer, etc. Working of CPU: Input(Instruction/action to perfrom)-> Processing(by CPU)-> Output (result)-> Storage.Д¬OMPUTER = Arithmetic Logical Unit (ALU) + Control unit (CU).ДЄrithmetic logical unit/ALU (accumulator) The Output further can be stored in the memory. Logical operations include: comparison at very high speed or comparison of values such as NOT, AND, OR.ДЄ data processor is consists of some form of memory, central processing unit.Д¬omputer works by taking input from the user as instruction, then process the input using its logical and arithmetical computational powers and gives out the processed result as output.Arithmetic operations include addition, subtraction, multiplication, division, etc.Hence, it is a device which is used to perform arithmetic operations as well as logical operations. The word computer has derived from the word вЂњcomputeвЂќ which means to calculate. Information is called the proper processed collection of the data.Data is called the raw material of the information, knowledge.

It is also called Personal computer (PC), data processor, laptop computer, word processor, etc. Computers are used to store data, followed by the given instructions. Computers are widely used all over the world to speed up their works and to build up the majority of things in their lives, such as food, entertainment, communication, transportation, etc. It is used to perform different types of functions such as processes, calculations, operations based on the instructions given by a software or hardware program.

How we can maintain ourВ systemвЂ™sВ quality to be good?Д¬omputer is a machine which includes both electronic as well as digital working.
