Software is?
The necessity of using the software
Software (software) refers to a set of instructions or programs used to operate the computer. Software refers to the sequence of steps that are written by the command of the computer. These commands are arranged in a computer program. As we all know now how computers work orders. The basic operation is simply to act on information as binary numbers. The data are used instead of numbers, letters, pictures or even to speech time.
A computer program used to work as a computer software. Because the sequence of the computer. One computer to work with many different software, different. The software is meant to include all types of computer programs that make the computer work.
We see we have a lot of computer work. Because we have developed a computer program to operate a computer. Stores may use accounting is complex. Ticket sales company providing computerized ticketing system. Computers in the business and banks that have many different computer and print documents to a stunning example of a computer to perform a tremendous benefit to the software. The software is an important part of the computer system. If the software does not work. Software, so it is necessary And more importantly, And a component of the system is going to be needed.
Software and computer languages.
If men want to use a computer at work. Man must tell the computer where algorithms. To tell the computer to recognize the human understanding. And working correctly Require a mediator Compared with daily life. We have used language to communicate with each other. Likewise, if people want to convey to the computer to recognize and act upon. To be a medium for the interface to the computer to recognize. We call this medium that language.
As computers with an electrical signal. Represented by the numbers 0 and 1 is a computer designed using the numbers 0 and 1 is the code for the command to run the computer. Code representation of data and commands using the binary system. Computer can understand We called binary elements in a set of instructions and use the computer that much.
Using this machine, the computer will immediately understand. But human users will have much trouble. It is difficult to understand and remember Is there a computer in the form of a letter. The sentences Such language is called. High level computer language There are many high-level language Some languages are more suited to the command of math and science. Some languages are appropriate to the execution of data management.
In the computer Computer to translate high-level language into machine language. Therefore, it has developed a computer program for high-level computer language into machine language. The program uses a high-level computer language into machine language called compiler (compiler) or pre-router interface. (interpreter)
The compiler will translate programs written in high level language program into machine language before. Then the computer running the machine language.
The pre-router interface will be translated by the command. Then the computer to follow instructions. When finished, it will translate to the next command. The difference between the compiler and interpreter pre-router is in the translation of the entire program or translation of a statement. Translator known as BASIC interpreter. COBOL compiler
This kind of software
Among the software or computer program is developed to use the computer a lot. These software may be developed by the users themselves. Or the development of Or manufacturer If the software division of the working conditions. The software is divided into two types: system software (system software) and application software (application software).
software The software vendor created to manage the system. Functions of the software system is a basic operation of a computer system, such as the data from the keypad characters and interpret the computer understands. The data to be displayed on a monitor or released to the printer. Management information system data files on the secondary memory.
When we turn on the computer As soon as the power supply to the computer. The computer will run the program, The first application is a computer running the software system. The software may be stored in ROM. Or on magnetic disc If no system software PC will not work
The software system is also used as a tool for development of other software and also includes the software used to translate different languages.
application Software The software is used for the various needs of users. That can be used directly. Currently, the development of various software released much. So extensive and pervasive computing applications. We may be divided into two groups: the application software. software successfully And software developed specific applications. At present there are many software packages such as word processing software. Spreadsheet software, etc.
Software System
Computer consist of input output units, memory and processor. In the computer is required to operate the equipment as needed basis. Therefore, the software system used to manage the system. The main functions of the software system consists of
Used in the management unit of input and output units such as pressing different keys on the keypad characters. Send a letter to a monitor or printer. Contact Input Devices And other output devices such as mouse, sound synthesis.
Used to manage memory. The data from the main memory card packaging. Or vice versa The data from the main memory is stored in the memory.
Used as an interface between the user and the computer. Can be easily used as a directory list in memory. Copy file
Software based systems commonly seen. There is an operating system And translators This causes two types of software application development easier.
operating System
operating System Also referred to as OS (Operating System: OS) is the software used in computer systems. All computers have the software operating system. The operating system is the most widely used and well-known as DOS (Disk Operating System: DOS) Windows (Windows) OS II (OS / 2) Linux (UNIX).
1) DOS is a software system that developed long ago. Then use the command as a character. DOS software is well known among computer users.
2) Windows is an operating system developed from DOS. To highlight the work easier. Can run multiple applications simultaneously. Each task is framed by the window displayed on the screen. Using the graphical form. The user can use the mouse to move the cursor to select a location on the screen. Make the computer easier to use Windows service that is popular today.
3) OS Two operating systems as well as Windows. The company is developing IBM The operating system that allows users to run multiple applications simultaneously. And use it as a graphical as well as Windows.
4) UNIX operating system that evolved from the use of this mini computer. Operating system UNIX operating system that can run multiple applications simultaneously. And perform multiple tasks at the same time. UNIX is used with a link and a chill multiple destinations simultaneously.
There are many operating systems The operating system used in computer networks. To make the computer work together as a system, such as NetWare operating system. Windows NT
Translator
In software development, software is needed for the high-level language. The high-level language into machine language. There are many high-level language These high level language created to allow the programmer to write a set of instructions are easy to understand and can update the software later.
High-level language developed to be a translator for translation. High-level language, which is known and very popular today, such as Pascal, BASIC programming language, and Logo.
1) Pascal is a computer in the form of a structure. Computing a written procedure. Authors can divide the work into small pieces and then combined into a larger program.
2) BASIC language with syntax hassle. To learn and understand. Have formed the basic commands that can be written as a sequence program.
3) language is the language that is suitable for use in other software development language is the language of structural flexibility for programming a computer to communicate with other devices.
4) Logo is ideal for learning and understanding of the Logo was developed for children.
Besides the already mentioned languages There is a computer language used in the present many languages such as Fortran, COBOL IBM RPG.
Software Documentation
The computer technology has developed rapidly. Only by a small computer. Therefore the use of agile. It is now able to bring a small computer. Ready to use in a different place.
The computer must have software applications ranging software application. This could be achieved with the development of software applications to make work easier. Or it could be software only. The user interface is developed in order to suit the conditions of their work.
software successfully
Among the software applications that are commonly used. Software package (package) is a software that is used is very high. Software is a software development company based success. Then put on sale To allow users to buy directly. Do not waste time to develop the software. Software packages available in the market. And popular, the user has five major groups, word processing software (word processing software) software function table (spread sheet software) database management software (data base management software) software offers. (presentation software), and data communications software (data communication software).
1) word processing software Is a software application for printing documents can edit, add, insert, delete and format documents as well. The document is printed in the data file. Call for printing or editing a new one. Printing on a printer, there is a character in a variety of formats. It looks neat, beautiful document Nowadays, with the empowerment of many word processing software. Popular word processing software in the industry such as CU writer Edward Ivins Lotus Ami Pro.
2) Software Operating Table Is software that allows for calculation. The software running the table The principle of virtual work desk with a large paper placed. There are tools like calculators, pens, erasers and prepared to finish. On paper, a box to enter a number. Text or formula Can be calculated according to the formula or conditions. The software can work table processing applications other figures widely used spreadsheet software such as Excel, Lotus works.
3) database management software Computing is the use of data. And deal with the data stored in the computer. Need a data management software. Crawl many issues related to the computer. I called a database Database management software refers to software that helps to keep. Exploring the use of a report on the conclusions from the data. Database management software that is used as a major process based Paradox Fox bass.
4) Presentation Software The software used for data presentation. The display must be able to attract. This software is the software that can display text in a way that is meaningful, it is easy to generate charts, graphs and photos are examples of presentation software such as Power Point. Lotus Freelance Harvard Graphics Card
5) data communications software Data communications software refers to software that allows the computer to communicate with another computer in the remote location. Through a phone line Communications software used to connect to a computer network such as the Internet makes it possible to use additional services can be used to send and receive electronic mail. Using file transfer The exchange of information sharing is also used to connect into a minicomputer or mainframe. To run from them. Data communications software with many popular software such as Prokom Crosstalk pouring lip.
Specific software
Applications with software packages tend to emphasize common use. But may be applied directly to the business, some are not. For example, in the bank The deposits Of accounting Or in the mall, they have to sell. Issuing receipts Inventory control Therefore, the development of software applications specifically for each application to meet the needs of individual users.
The software is a software developer to work or to study the needs of businesses that already prepared. Basically it is a many common software to work together. The software used in the business such as accounting systems. Distribution System Systems in industrial plants financial Management And leasing
The needs of computer use in business applications has increased greatly. Therefore, the demand for software developers to develop specific applications and much more
