What Is Abstract Machine

Such a model usually consists of input output and operations that can be preformed the operation set and so can be thought of as a processor. Abstraction of computing processes is used in both the computer science and computer engineering disciplines and usually assumes a discrete time paradigm. When we write a program we dont want to think about the differences between all these platforms.

For a real machine these resources actually exist as tangible objects each of the type expected.

What is abstract machine. An abstract machine also called an abstract computer is a theoretical model of a computer hardware or software system used in automata theory. An abstract machine is a model of a computer system considered either as hardware or software constructed to allow a detailed and precise analysis of how the computer system works. Abstract machine a machine can be thought of as a collection of resources together with a definition of the ways in which these resources can interact. An abstract machine also called an abstract computer is a theoretical model of a computer hardware or software system used in automata theory.

For example addressable storage on a real machine will actually consist of the appropriate number of words of storage together with suitable address decoders and access mechanisms. Abstract machines also called automata are an element of theoretical computer science. Abstract machines differ from more literal machines because they are assumed to function perfectly and independently from hardware. It receives inputs and produces outputs according to specified rules.

A wide variety of operating systems and plethora of hardware ensures a bewildering number of things we call computers. Abstraction of computing processes is used in both. An abstract machine resembles a function in mathematics. Abstract machines are the core of what defines a programming language.
