Fundamentals of COMPUTER KNOWLEDGE

          hey guys today I will discuss beginning of computer knowledge today is 1st day so today I come to the point computer (what is computer, some definition that clear all doubts related computer,and last detail of computer work but if u want gain knowledge about today discussion deeply so click this like you I hope you understand deeply and I sour your knowledge increase day by day throw my daily computer basic knowledge .            

         DAY 1.     

                    COMPUTER KNOWLEDGE

A COMPUTER

Human nature is full of curiosity. For the simplicity of life he always involves in new innovations. One of these innovations is 'computer.' It means to calculate. We all are familiar with calculations in our daily life. We various mathematical operations for calculations. All of us, know about

calculators, we use calculators to do some simple calculation which takes less time. But complex calculations take much longer time. Another factor is accuracy in calculations. So, a machine was developed which can perform this type of arithmetic calculations faster and with full accuracy. This gave birth to machine or device called 'computer". The name computer is given to that because firstly it is used to computer or in computing (calculations). It can store a large number of data, can operate large number of calculations with in few seconds, and accurately. 

Definitions 

A computer can be defined in the following manner:

        • "Computer is an electronic data processing machine." 

        • "Computer is an electronic is an electronic device capable of performing arithmetic and      logical  operations."

       • "Computer is an electronic device." 

       • "Computer is a device that transforms data. " 

       • For a common man "It is simply a calculator, which works automatic quite fast."

•  for an individual who knows much about it, computer is a machine capable of solving problems and manipulating data. 
• Computer can be defined in terms of its function. "It can accept data, store data, process data as desired, retrieve the stored data as and when required and print the results in desired, retrieve the stored formats ." 
• It is a tool that can be used during instruction to do complex calculations, data manipulations and word processing. 

                                             

Therefore, on the above discussion, it can be concluded that :

    Thus, "Computer is an electronic device which can store, retrieve and process quantitative and qualitative data fast and accurately." Now as days computer has become a part of our daily life. It can be used in all aspects of our life. Today, a variety of routine works are being performed by computers.

 DAY 2:-          

 The main work of computer is to analyse the information and to present true  and reliable result after processing In this, with different part computer, the different agents are also important to operate the computer

                            Agents /Element of Computer

Different parts of computer and these agents together built a computer system. These agents are hardware, software, firmware, skin ware and humaware .

1. Hardware  -   All those components of computer, that can be touched seen, are called Hardware. All internal and external parts of a computer. pt and output devices of computer etc., are the examples of hardware. The devices, necessary to operate the computer are called standard devices: eg key-board, floppy drive, hard disk etc., and devices that are connected to computer e g. mouse, printer, light pen, plotter etc., are called peripheral devices. The collecting form of standard and peripheral devices the s called hardware. 

2. Software-  The series of instructions in the form of programs written and run on a computer is called the software. These are the programs which are executed by the computer.

 The software is further sub-dived into two types. 

These are :i)System Software    (ii) Application Software

 i) System Software-The set of pre-written programs incorporated into the memory of a computer by the manufactures is called the System Software example-Operating system, language compilers and interpreters.

 (ii) Application Software-The set of programs written for the use of the consumer/user is called the Application Software'. For example-Bank accounts payrolls, bills etc.

3. Firmware-   The combined form of hardware an  d software is called firmware. The hardware or storage medium in which software has installed, would be called firmware.

 4. Skinware- The components of computer, which can be seen without opening the computer are called skinware, eg. monitor, key-board, mouse, printer etc.  eg computer seller, computer operator, computer.

 5. Humanware-All human related with computer are called programmer, computer teacher, computer student etc. Humanware is also called liveware. Software It is compulsory to give instruction to computer that when, how and what to do. These instructions are written serially in computer language is group of serially arranged instructions is called program or software.
