SYSTEM SOFTWARE Basic concepts, facts Definition and classification of STR. Requirements for free software. Basic and service free software. OS. File management systems. System utilities. Programming systems. Skills and skillsDevelopment of system software in accordance with the requirements for ACT in the languages Assembler, C ++. Installation and use of system utilities. Classification of software Traditionally, all software is divided into two classes: 1) system software (SPO) and 2) application (user) software (SPO). We will highlight one more class (rather group of programs) - special software for information and control systems.

Application programs are designed to solve functional problems, they perform information processing of various subject areas. This is the most numerous class of software products. To the special software of information and control systems are • Programs (systems) for managing databases; • Language interface programs for information systems; • Programs for collecting and preliminary processing of information (in information-measuring systems, for example, on-board systems). The software of this class often turns out to be hidden in the hardware drivers or is delivered as libraries of functional extension of programming languages. Therefore, often such software is referred to as system software. We will consider a software of this type as a separate class and will not be considered. System Software (System Software) - a set of programs and software to support the operation of the computer and computer networks. The SPO manages the resources of the computer system and allows users to program in more expressive languages than the machine language of the computer. The composition of the ACT depends little on the nature of the user's tasks. Purpose of the system software The system softw

This class of software products is closely related to the type of computer and is its integral part. Software products of this class are mainly targeted at qualified users - computer professionals: system programmer, network administrator, application programmer, operator. However, knowledge of the basic technology of working with this class of software products is required for end users of the personal computer who independently not only work with their programs, but also maintain the computer, programs and data. Software products of this class are of general application, regardless of the specific domain. System software products are subject to high demands for reliability and workability, convenience and efficiency of use. Classification of system software The STRs traditionally include • System management and • System processing programs. Control system programs organize the correct functioning of all devices of the system. The main system functions of control programs - • Management of computing processes and computer systems and • Work with internal OS data. As a rule, they are in the main memory. These are the resident programs that make up the OS kernel. Control programs th

Processing system programs are executed as special application tasks, or applications. These programs are delivered more often in the form of distribution packages that include software Comment. In packages of system programs, in addition to the main programs that allow reconfiguration, there are special tuning programs called installation programs. Other classification Often the system software of a computer is divided into BASIC and SERVICE software. BASIC software (base software) - the minimum set of software tools that ensure the operation of the computer. The basic software of the computer is • Operating systems and drivers in the OS; • Interface shells for user interaction with OS (operating shells) and software environments; • File management systems. Operating system - a set of software that…
