Components of a software system

Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system hardware. System software sru computer science slippery rock university. A software component infrastructure is a set of interacting software components designed to ensure that a software system or sub system constructed using. A computer system consists of three major components. The primary piece of system software is the operating system, such as windows or ios, which manages the hardwares operation. The purpose of system software is to protect the applications programmer from the complexity and specific details of a particular computer being. Software component of a pc is the system software and the. A software system is a system of intercommunicating components based on software forming part of a computer system a combination of hardware and software. The goal of component based software development is to allow developers to construct a software system by integrating existing software components in a plugandplay manner 1 like assembling mechanical hardware or furniture in daily life. Components are largegrain functional units of systems and architectures represent blueprints describing system composition. It consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system.
