Operating systems supervise the low-level operations of the hardware of the machines they run on. They make use of CPU features, such as privilege levels and dynamic address translation, which exist primarily to support the operating
system. As a result, operating systems are inherently architecture-dependent.
Difference Between Software Architecture and Software DesignSoftware Architecture focuses more on the interaction between the externally visible components of the system where as the Design is about how the internal components of the system interact with each other.Software Architecture is more about what we want the system to do and and Design is about how we want to achieve that.Software architecture is at a higher level of abstraction than the Software Design.Software Architecture is concerned with issues beyond the data structures and algorithms used in the system.
Enterprise software architecture relates to architecture of enterprise-scale systems i.e. large and complex systems or systems of systems in support of enterprise processes. System software is like any other operating system used on a computer to keep it running.
The software architecture of a system is the set of structures needed to reason about the system, which comprise software elements, relations among them, and properties of both. The term also refers to documentation of a system's "software architecture." Documenting software architecture facilitates communication between stakeholders, documents early decisions about high-level design, and allows reuse of design components and patterns between projects.
1) Instruction format and addressing modes. 2) Relocation. For details refer "System Software By L.L.Beck" BY:: SUNIL SHARMA (sunil13982@gmail.com)
N-tier software architecture refers to a method of designing a system. In this system, the presentation, application processing, and data management are logically done separately from each other.
There are several reasons why system software is close to the system. The biggest reason is that without the system software the programming would not work properly. They system software is what runs the machine.
The machine was the EDVAC computer.
Perspective architecture is the architecture as conceived. Typically this architecture is realized by the system architects. It represents the set of architectural ideas as gathered by the system architect through his understanding of the system. Descriptive architecture on the other hand represents the the architecture as realized for implementation. Programmers and system designers realize this architecture. It may be different than that of perspective architecture as it represents ideas gathered by system programmer through his experience.
architectural framework means synthesizing of various existing resources like databases,computer languages,software agent based transaction,monitors on communication protocol to facilitate the integration of data and software for better application.
It is a type of software that convert programe into machine language
3 level of software design - Architecture - Component - Detailed
System software is the software that usually runs the machine such as Windows 7 or other operating systems. Utility software is software that is used to perform small tasks such as drivers and anti virus.
