Why it may be necessary to design the system architecture before the specification are written?

The architecture have to be designed before specifications are written, because
• to provide a means of structuring
• the specification and developing different sub-system specifications concurrently
• to allow manufacture of hardware by sub-contractors
• and to provide a model for system costing.
Writing specification for the whole system might bring great complexity and it is difficult to formulate it.
Therefore, it is easier to divide the system into simpler subsystems and define their specification and it will save you the hassle of defining specification and put it into the respective subsystem.
Hence we can concurrently develop subsystems and the specifications to be readily into the implementation stage.

What are the difference between computer organization and computer architecture?
Computer organization is how operational attributes are linked together and contribute to realise the architectural specifications.Computer architecture is the architectural attrributes like physical address memory,CPU and how they should be made and made to coordinate with each other keeping the future demands and goals in mind.Computer architecture comes before computer organiation.Its like building the design and architecture of house takes maximum time and then organisation is building house by bricks or by latest technology keeping the basic layout and architecture of house in mind.

What is assembler and interpreter?
There are two types of assemblers based on how many passes through the source are needed to produce the executable program.One-pass assemblers go through the source code once. Any symbol used before it is defined will require "errata" at the end of the object code (or, at least, no earlier than the point where the symbol is defined) telling the linker or the loader to "go back" and overwrite a placeholder which had been left where the as yet undefined symbol was used.Multi-pass assemblers create a table with all symbols and their values in the first passes, then use the table in later passes to generate code.
How do you read a civil drawing?
Before reading any civil drawing we must understand the purpose of each line, word, symbol, appreviation and specification referred to, as to indicate the construction team required to do the attempted works.
What are specification languages. Give an example?
A specification language is a formal language used in computer science. Unlike most programming languages, which are directly executable formal languages used to implement a system, specification languages are used during systems analysis, requirements analysis and systems design.Specification languages are generally not directly executed. They describe the system at a much higher level than a programming language. Indeed, it is considered as an error if a requirement specification is cluttered with unnecessary implementation detail, because the specification is meant to describe the what, not the how.A common fundamental assumption of many specification approaches is that programs are modelled as algebraic or model-theoretic structures that include a collection of sets of data values together with functions over those sets. This level of abstraction is commensurate with the view that the correctness of the input/output behaviour of a program takes precedence over all its other properties.In the property-oriented approach to specification (taken e.g. by CASL), specifications of programs consist mainly of logical axioms, usually in a logical system in which equality has a prominent role, describing the properties that the functions are required to satisfy - often just by their interrelationship. This is in contrast to so-called model-oriented specification in frameworks like VDM and Z, which consist of a simple realization of the required behaviour.Specifications must be subject to a process of refinement(the filling-in of implementation detail) before they can actually be implemented. The result of such a refinement process is an executable algorithm, which is either formulated in a programming language, or in an executable subset of the specification language at hand. For example, Hartmann pipelines, when properly applied, may be considered a dataflow specification which is directly executable. Another example is the Actor model which has no specific application content and must be specialized to be executable.An important use of specification languages is enabling the creation of proofs of program correctness (see theorem prover).LanguagesCASLVDMZ notationLePUS3 (a visual, object-oriented design description language)PerfectKumud Patel +919999659026, +917677788016
How do you prevent oil rigs from rusting?
When oil rigs are constructed, they are coated with rust inhibitors before they are painted. The structure is constantly monitored for rust and is re-coated where necessary.
