Software systems are built on a hierarchy of components. Each component provides a service or performs a specific task. The architecture of a system depends on the data it processes. A high-level design shows the system architecture in terms of modules and their logical relationship. It also shows the interaction between each sub-system. The detailed design involves the implementation of the system and its sub-systems. It involves defining the logical structure of each module and the interfaces to communicate with other modules.
A computer’s hardware contains various software components that support and enhance it. For example, the basic input-output system contains routines for peripheral devices and internal services. It also accepts requests from application programs and operating system device drivers. It also includes autostart functions, which test the system on startup and pass control to the operating system.
A software system is a collection of computer programs, associated documentation, and configuration files. It is the foundation of a computer system and manages its resources. Its design and implementation will have a strong impact on the quality of the system’s performance, maintainability, and success. A software system may include several architectural styles, principles, and patterns.
Software is durable, but it can develop bugs over time. However, these bugs can be fixed. There are four basic types of software that are considered system software. These categories include applications, driver software, programming software, and system software.
