Computer System
The Computer System is not an electronic genius; on the contrary, if anything, it is an electronic idiot, doing exactly what we tell it to do. İf has no mind of its own. What appears to be a very complex organism a really a huge interconnected collection of very simple parts. In this course these simple parts will be interested, and step by step uild the interconnected structure, that you know by the name computer.
Hardware à The physical computer
Software à Programs, operation systems ( Vista, xp, pardus…)
A computer system, it directs the processing of information and it also performs actual processing of information.
· When we say ‘directing’ the processing of information we mean-figuring out which task should get consider at next.
· Performing the actual processing means doing the actual addition, multiplication sof ast that and rewising to get the job down.
· These are two ideas that are the case of what computing is all about.
1. All computers ( the biggest and the smallest, the fast and the slow ) are capable of computing the same things if they are given enough line and enough Money.
2. We describe our problems in English or same other languages spoken by people. Yet the problems are solved by running around inside the computers. It is necessary to transform our problems from the language Y forms to the voltages that influence the flow of electronics. This transformation is really sequence by systematic transformation developed and improved over the last 50 years, which carbine to give the computer ability to carry out what appears to be very complicated tasks.
The Statement Of The Program
We describe the problems we wish to solve wit a computer in a Natural Languages are languages that people speak.
The Algorithm, the first step in the sequence of transformations is to transform the natural language description of the problem to can algorithm.
An algorithm is step-by-step procedure that is guaraneed to terminate, such that each step is precisely stated and can be consider about by the computer
