is a functional description of requirements and design implementation for the various parts of computer. It deals with functional behavior of computer system

describes what the computer does

describes how it does it

….. comes after the decide of …. first

deals with functional behavior of computer system

deals with structural relationship

It deals with the components of a connection in a system

It acts as the interface between hardware and software

indicates its hardware

involves Physical Components (Circuit design, Adders, Signals, Peripherals)

involves Logic (Instruction sets, Addressing modes, Data types, Cache optimization)

indicates its performance

Multiplication is an example of

Multiplication circuit or Shift circuit

Intel, AMD use …. Architecture, utilize ….organization

For less values of shift moves, Shift/Add circuits are slower (low speed) than multiplication circuit

Compiler can convert Multiplication operations into Shift/Add operations

The operation of each individual component as part of the structure

The way in which the components are interrelated

image conversion is an example of indexing

indexing is the indexing of large datasets created by Web crawler engines
