How distributed information system helps global organization?
A distributed information system consist of multiple autonomous computers that communicate through a computer network.and the computers interact with each other in order to achieve a common goal. A computer program that runs in a distributed system is called a distributed program. example:- Telecommunication network
What does runtime mean?
actually the run time means at the time of executing the program. that means if you write a program and you compile it and you need to execute then during the compilation it is called compile time and during the execution it is called run time .
What is impure procedure?
Set of instruction which form a program gets changed during the course of execution by that instruction behave differently is called impure procedure
What are types of Distributed Denial of Service DDoS attacks?
DDoS attacks, spoof attacks, and a newer program called a stresser are the most common types.
What is the postponement of the execution of a sentence is called?
It is called a stay.
What is an instruction phase together with the execution phase called?
The instruction phase together with the execution phase is called a "Machine Cycle".
What is use of registers?
It holds the operation code .that is the opcode of the current instruction of the program during the arithmatic and logic operation......it is also called single cycle execution(only one perform)
When was the execution of fannin and many of his soldiers?
The execution occurred on March 27, 1836. It was called the Goliad Massacre.

Why is a molecule in which charges are unevenly distributed called a polar molecule?
Because the eletronic charges are unevenly distributed, that's why it's called polar.
Explain language processing activities with suitable diagrams?
Language processing activities arise to bridge the ideas of software designer with actual execution on the computer system. Due to the differences between the manners in which a software designer describes the ideas concerning the behavior of software and the manner in which these ideas are implemented in a computer system. The designer expresses the ideas in terms related to the application domain of the software. To implement these ideas, their description has to be interpreted in terms related to theexecution domain of the computer system. We use the term semantics to represent the rules of meaning of a domain, and the term semantic gap to represent the difference between the semantics of two domains. The fundamental language processing activities can be divided into those that bridge the specification gap and those that bridge the execution gap.· Program Generation Activities· Program Execution ActivitiesA program generation activity aims at automatic generation of a program. The source language is a specification language of an application domain and the target language is typically a procedure oriented PL. A program execution activity, organizes this execution of a program written in a PL on a computer system. Its source language could be a procedure-oriented language or a problem oriented language.o Program GenerationThe program generator is a software system which accepts the specification of a program to be generated, and generates a program in the target PL. We call this the program generator domain.The specification gap is now the gap between the application domain and the program generator domain. This gap is smaller than the gap between the application domain and the target PL domain.Reduction in the specification gap increases the reliability of the generated program. Since the generator domain is close to the application domain, it is easy for the designer or programmer to write the specification of the program to be generated.Fig. 1.3: Program generator domainThe harder task of bridging the gap to the PL domain is performed by the generator. This would be performed while implementing the generator. To test an application generated by using the generator, it is necessary to only verify the correctness of the specification input to the program generator. This is a much simpler task than ver­ifying correctness of the generated program. This task can be further simplified by providing a good diagnostic (i.e. error indication) capability in the program generator, which would detect inconsistencies in the specification.It is more economical to develop a program generator than to develop a problem-oriented language. This is because a problem oriented language suffers a very large execution gap between the PL domain and the execution domain, whereas the program generator has a smaller semantic gap to the target PL domain, j which is the domain of a standard procedure oriented language. The execution gap between the target PL domain and the execution domain is bridged by the compiler or interpreter for the PL.o Program ExecutionTwo popular models for program execution are· Translation· InterpretationProgram TranslationProgram translation model bridges the execution gap by translating a program written in a PL, called the source program (SP), into an equivalent program in the machine or assembly language of the computer system, called the target program (TP).
