Software is system code on a computer. Most software comes in the forms of programs that you can download or buy and install. Hardware, however, is the physical components of a computer system.
No. It is a noun meaning utensils, tools, implements, or the physical parts of a computer system. It can be used as an adjunct with other nouns such as hardware platform, hardware error, or hardware store.
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.
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.
It is the art of assembling logical elements into a computing device; the specification of the relation between parts of a computer system.
