Computing - Wikipedia

Thus, computing includes designing and building hardware and software systems for a wide range of purposes; processing, structuring, and managing various kinds of information; doing scientific studies using computers; making computer systems behave intelligently; creating and using communications and entertainment media; finding and gathering information relevant to any particular purpose, and so on.

The list is virtually endless, and the possibilities are vast. Computing also has other meanings that are more specific, based on the context in which the term is used.

For example, an information systems specialist will view computing somewhat differently from a software engineer. Regardless of the context, doing computing well can be complicated and difficult.

Because society needs people to do computing well, we must think of computing not only as a profession but also as a discipline. The term "computing" has sometimes been narrowly defined, as in a ACM report on Computing as a Discipline: The fundamental question underlying all computing is "What can be efficiently automated?

In earlier times, it was used in reference to the action performed by mechanical computing machinesand before that, to human computers [ citation needed ]. History of computing and Timeline of computing The history of computing is longer than the history of computing hardware and modern computing technology and includes the history of methods intended for pen and paper or for chalk and slate, with or without the aid of tables.

Computing is intimately tied to the representation of numbers. But long before abstractions like the number arose, there were mathematical concepts to serve the purposes of civilization.

These concepts include one-to-one correspondence the basis of countingcomparison to a standard used for measurementand the right triangle a device for assuring a right angle. The earliest known tool for use in computation was the abacusand it was thought to have been invented in Babylon circa BC.

Its original style of usage was by lines drawn in sand with pebbles. Abaci, of a more modern design, are still used as calculation tools today.

Knowledge Base The business took off, and its founders made a lot of money and received the credit they deserved for being daring visionaries.

This was the first known calculation aid - preceding Greek methods by 2, years[ citation needed ]. ComputerOutline of computersand Glossary of computer terms A computer is a machine that manipulates data according to a set of instructions called a computer program.

How to predict the near future

The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, enables a programmer to study and develop a sequence of steps known as an algorithm. Because the instructions can be carried out in different types of computers, a single set of source instructions converts to machine instructions according to the central processing unit type.

The execution process carries out the instructions in a computer program.Unfortunately, the Be bug reporting system strips off the names of the people who report the bugs (to protect them from retribution!?) and so I don't know who wrote this.

And you also have to know what being ignorant is. Ignorant is just another word for "Not knowing".But not knowing is not always obvious or clearly nationwidesecretarial.com's because learning is not fully understood.

The more you learn the more you should realize what you didn't know.
