How Does the Software Work (सॉफ्टवेयर कैसे काम करता है)

Software is the computerised instructions that operate the computer, execute particular functions

or tasks, and manipulate the data. For software (the instructions) to perform various functions, it must be programmed. That is, the instructions need to be written in a programming language that the computer can understand. Without a program, a computer is useless.

Programming language An artificial set of rules, vocabulary and syntax used to instruct the computer to execute certain tasks.

Computer program A sequence of instructions that can be executed by a computer to carry out a process. Over the years, a wide range of programming languages have been developed, including BASIC, FORTRAN, PASCAL, C++, JAVA, and so on. Each language has a unique set of words (codes) that it understands and a special syntax for organizing

program instructions.

The language the computer actually understands is called machine language, which comprises numbers only. This language is used by the computer to understand the programming language and translate the terms into executable instructions. Lying between programming languages and machine languages are assembly languages. Assembly languages have the same structure and set of commands as machine languages but they enable a program to use names instead of numbers.

Most people who use computers today do not need to worry about programming, machine, or assembly languages. This is because the software being used today is written in a highly user-friendly manner and in a way that does not require knowledge of the computer languages which were used to

create and use it.

User friendly Computer software or hardware that is simple to set up, run and use. There are two kinds of software, systems software and applications software.

Systems software includes the operating system and all the utilities that enable the computer to function. The most important program that runs on a computer is the operating system. Every general-purpose computer must have an operating system in order to run other programs. This includes controlling functions such as the coordination of the hardware and applications software, allocating storage facilities, controlling the input and output devices and managing time sharing for linked or networked computers. The Windows family of operating systems includes a aphical User Interface (GU) that makes the software user friendly.

Operating system A collection of software that allows a computer to function.

Applications software includes programs that users access to carry out work. They include applications for the following functions

Word processing is the most common applications software. The great advantage of word processing over using a typewriter is that you can make changes without retyping the entire document. word processors make it manipulate and format documents.

Spreadsheets are computer programs that let people electronically create and manipulate spreadsheets (tables of values arranged in rows and columns with predefined relationships to each other). Spreadsheets are used for mathematical calculations such as accounts, budgets,statistics and so on.

Database management applications are computer programs that let people create and manipulate data in a database. A database is a collection of related information that can be manipulated and used to sort information, conduct statistical analyses or generate reports.

Presentation packages and graphics are computer programs that enable users to create highly stylised images for slide presentations and reports. They can also be used to produce various types.of charts and graphs. Many software applications include graphics components including: paint programs, desktop publishing applications and so on.

Communications applications typicaily include software to enable people to send faxes and emails and dial into other computers

Software programs are continualy being written or upgraded to undertake certain tasks, As a result, the software can become obsolete quickly.

Software can be either 'proprietary' (also called 'closed) or open'

Proprietary software is privately owned and controlled.A proprietary software design or technique is one that is owned by a company, which will usually not divulge specifications that would allow other companies to duplicate the product. Increasingly, proprietary software is seen as a disadvantage in many organizations. Open sofitware is the software designed using specifications that are publicly accessible. The great advantage of open software is that anyone can create add-on products for it because they can understand how it was designed. People using open software can mix and match products from different manufacturers.

what is computer/कम्प्यूटर क्या है

कम्प्यूटर क्या है? कंप्यूटर एक उपकरण है जो इनपुट को स्वीकार करता है, इसे संसाधित करता है, यदि आवश्यक हो तो डेटा संग्रहीत करता है और उपयोगकर्ता की आवश्यकता के अनुसार वांछित आउटपुट देता है। कंप्यूटर शब्द का उपयोग इलेक्ट्रॉनिक और इलेक्ट्रोमैकेनिकल (पार्ट इलेक्ट्रॉनिक और पार्ट मैकेनिकल) घटकों के संयोजन से बने डिवाइस का वर्णन करने के लिए किया जाता है। अपने आप में, एक कंप्यूटर में कोई खुफिया नहीं है और इसे हार्डवेयर के रूप में संदर्भित किया जाता है। सामान्य तौर पर कंप्यूटर निम्नलिखित कार्य करता है। 1. उपयोगकर्ता आपूर्ति डेटा और निर्देशों को स्वीकार करें। 2. दिए गए निर्देश के अनुसार उच्च गति पर दी गई बड़ी मात्रा में जानकारी संग्रहीत करता है। 3. दिए गए निर्देश के अनुसार उच्च गति पर दी गई जानकारी को संसाधित करें। 4. उपयोगकर्ता विनिर्देशों के अनुसार परिणाम आउटपुट करें 5. बहुत तेज दर पर केबल के माध्यम से डाटा, इमेज, साउंड और ग्राफिक्स ट्रांसफर करता है दूसरे शब्दों में, हम कंप्यूटर को आपूर्ति करते हैं; संसाधित होने के लिए डेटा और निर्देश डेटा के साथ प्रक्रिया। कंप्यूटर डेटा और न...
