The term Software Requirements Specification (SRS) can be given a very exact and well defined meaning -- that of a document as outlined in IEEE Standard 830.

A standard SRS addresses functionality, interfaces (user, hardware and other systems), performance, other attributes (e.g. portability, security) and any design constraints (e.g. particular language or platform). [Section 4.1]

A standard SRS should not go beyond specifying requirements, in particular it should not include any design or implementation details, e.g. specific screen design, although the user interface section may include logical formats or layouts. [Section 4.2]

A good SRS should have the characteristics of: correct, unambiguous, complete, consistent, ranked for importance, verifiable, modifiable, traceable. [Section 4.3]

An SRS should be jointly prepared by the customer and supplier (of the software). [Section 4.4]

The SRS should only contain product requirements, not project requirements, i.e. it should not contain costs, schedules, development methods, acceptance procedures, etc. [Section 4.8]

In contrast the terms functional requirement/functional specification are defined in the IEEE Sandard 610.12 Glossary. As defined in the standard functional requirements are only one subset of the overall requirements, i.e. a functional specification often simply refers to one part of the requirements specification (SRS).

I don't think business requirements specification is a defined standard term, but from the descriptions is probably similar to the official meaning of SRS.

In practice, many people use different terms to mean many different things, but if you want an official definition of SRS I suggest sticking with the description in IEEE Standard 830.

RE: What is the difference between Business Requiremen...

BRS: BRS contains the basic requirements of customer that are to be developed as software project cost schedule target dates.

SRS: SRS is implemented form of BRS. SRS is often referred as parent document of project management document such as design specifications statmnets of works software architecture specifications testing and validation plans and documentation plans.The basic issues of SRS is what is the functionality(what is the s/w supposed to do)what are the external interfaces (how does the software interact with the user other hardware and other system software)performance(What is the speed of application recovery time response time availability of various software functions)attributes(what is the portability security correctness etc )design constraints (OS environments.implemnation of languages database integrity and resource limits)

SRS contains the functional and non functional requirements only.

FRS: FRS document provides the more detailed and described form of SRS.It contains the technical information and data needed to design the application. FRS define the what are software functionality will be and how to implement
