computer softwareabstract：in todays society, the application of computers is quite extensive. not only the way people work, learning and life changes, production and social activities are extremely important to the human impact of rapid development and strong vitality. it from the initial application of military scientific research area extends to all spheres of society, prove that the computer industrys scale is enormous, and led technology on a global scale, which led to a profound social change. computer not only in schools, enterprises and institutions working partners, access to common people, are indispensable tools in the information society, is one of the important symbols of the human into the information age.keywords:software development; software category; developmentintroduction:computers are made up of hardware and software, according to the encyclopedia of the chinese interpretation, the hardware refers to a variety of computing equipment and devices, and the word software refers to the program in the computer system and related files. software is the interface between the user and hardware interface. communicate with the computer user through the software. software is an important basis for computer systems design. for the convenience of the user, in order to make computer systems with higher overall utility in designing computer systems, integration of software and hardware must be global, as well as the users requirements, and software requirements. computer hardware function is entered and stored programs and data, and the procedures for processing the data into a form that can be used while software is like the human mind, is no thought without software like body and soul, cant do anything.software categorygeneral software is divided into system software, application software, management software, software, security software, multimedia software, game software, computer software systems can be divided into two part of system software and application software. system software is responsible for the management of the entire computer system resources, monitoring, maintenance of computer software, such as operating system, self and other. application software refers to individual users for their own needs in the different areas, and develop a variety of applications, such as personnel management, learning management software. and application software is the software solutions to specific problems from the functional point of view, is itself a computer logic functions reasonably working computer, simplify the process even instead of people using your computer working environment.system software system software is responsible for coordination of various independent of the hardware in the computer system. overall, the system software, including operating systems and database management, file system management, compiler, a basic set of tools, such as 3 network connections. system software consists of a set of controls comprising computer systems and procedures for managing its resources, its main functions are: to start your computer, load and execute the application, such as the translation of programming languages into machine language. system software also can be seen as user interface with the computer, application of software and hardware of the user control, access tools are mainly done by the operating system. application software application software was developed for a specific purpose. application software programming in general is available for users using computers to solve certain practical problems. it is a set of functions closely linked, can collaborate with collection of programs, such as microsofts office software; or it can be a specific program, such as an image viewer; can also be a large software system is composed of many independent processes, such as a database management system. system software tasks are two points: better use of your computers efficiency; more user-friendly. application software is prepared to resolve the practical problems of computer applications and related information. such as transaction management software: payroll system, financial system; for math ic spot in scientific computing packages, are application software such as finite element analysis software package.development of computer software with the fast development of software industry in china, increasingly fierce competition between software development enterprise, in order to improve the efficiency and quality of software development, proven project management policy must be taken. compared with the developed software industry, our general lack of good project management software development company concept and mode, resulting in the management of working hard to achieve the desired effect, seriously affect the software development cost, quality, schedule, and so on.under the background of the development of modern computer technology, software development as an emerging industry, this has the characteristic of creative, challenging. development of software industry in china is relatively short, lack of software development project management can learn from successful experiences, this is the main management issues faced at the present stage of software development enterprises, if not addressed in a timely manner, will seriously affect the development prospects of the domestic software industry. therefore, the need for project management in software development should not be ignored, but also to strengthen the research and practice on specific management strategies.software developmentuser-friendly software for the efficient completion of the those unusual lot of work there is a great deal of help, and the needs of people slowly started to emerge, different requirements at different levels in the field of software is causing the rapid breakthrough growth. statistics of users also led the software industry i
