Introduction to Computer-mail
Were not the idea of computer-modern, but as old as the human needs of a particular Assistant calculations therefore the use of human fingers to count the little things such as sheep, which is sponsored by, for example 0 and what is no longer the number of fingers sufficient human need for counting and calculation by using the gravel placed in the pod and match each Ejrabh pebble in one of his sheep if he was preparing his sheep, for example, and so on with the development of human life seemed to think the invention of his family to help in the completion of its accounts and its work, was the need to perform calculations the nucleus of the invention of the computer that we see today flying on top of human creativity 0
The computer is also called Computer (computer) is an electronic device performs mathematical and logical operations on a set of data and process it and get results (information) make use of it in our lives 0
Authorized the office is used basic computer is to do a mathematical and logical and all the work done by the computer is, after all calculations and logical 0, but what do we mean calculations and what we mean operations logical and what is data and what information is what is the difference between them is not nominal Xi one, Do not collect data on persons and things and enter them into the computer to give us the results we want?
Here you will learn about some of the terminology used in computer science and the difference between 0
What is the difference between the data and information?
We often hear people say that we collect information or enter information into the computer, if we are entering the information, what the size of the interest it then?
That there is a big difference between saying data (DATA) and we say information
(JNf0rmaTjoN) of the attention of the computer:
What is the data?
The data is a collection of facts and observations are collected from
Certain statistical community and entered into the computer for processing and output of Results 0
Examples include:
The student's name 'date of birth' entitled 'place of birth of' marks' the number of his brothers' date of entry school 'employee number' basic salary 'intermittent amount of the salary
Computation and Human
If the fundamental objective of the computer is to perform calculations as we have said we may ask ourselves as human beings can not be using paper and pen to the accounts without the computer? Is the computer and other functions? What are the areas in which the computer tells us that it? .
Let us begin to answer these questions to ask a question is simple: How will a person skilled in the account to tell us a matter of arithmetic if we say to him 8654 × 7678? .
May say that he needs to be half a minute or minute and do not forget that a minute is sixty seconds Did you know that the fastest computers in the world reached the speeds it can achieve (000'000'000'000'1000) (thousand million million) calculations in per second. Can we not say that a computer will make us a great benefit calculations quickly? .
What distinguishes a computer from the human speed enormous and accuracy of the finite and can be operated for long periods without fatigue or boredom or fatigue can also be used for different tasks, it is in the airport and at the clinic in the Archive At the police station with banks and banks in the offices of managers and coordinators.
Computer Date
As Oisilvna the idea of a computer as old as the human was the first means of calculation used by the human person is his fingers and then gravel then with the evolution of life and complexity was very to develop methods and techniques to suit the requirements of the times in which they live and at this growing spectacularly in the lives of human beings had to be offset by acceleration in the evolution of the idea of a parallel computer and the trend to be highlighted as one of the most important factors that help the progress of human 0
