Information Technology Something New?

When people hear the words technology information, first things which come to mind are the computers and the Internet. It can also evoke words like , of network , Intranet , waiter , wall fire resistant , of safety as well as, router, T-1 like more mysterious of expressions , Ethernet or the mysterious one and the exotic-repercussion VoIP (delivery voyp ).

In fact, the information technology is all these things, and more. He 's hardly new, however. The information technology is as old as the brain itself, if you think of the brain like processor of information. Until I.T being a science, even that turns over insofar as the attempts earliest to communicate and store information.

And it is primarily what is the information technology: the communication and the storage of information, with the capacity to deal and be useful themselves with stored information. In this chapter, we will start with a short history of I.T., which it comprises today, and various principal types of systems of I.T available today.

A short history of technology information

Because the human society developed in the face and complexity, thus has the need for collecting, for storing and for transmitting information. While it could discuss that the brains represent a form of technology of bio-information, Greek word Tektra - of what we obtain with the word with technology - really refers to the scientific knowledge or mechanics, in particular that which involves the use of the tools. Consequently, we will begin our voyage with the human ones initially tries to record and transmit knowledge by average mechanics.

The Neolithic period and the Bronze Age

We could not have thought of it as technology the information several thousand years ago when us while the species painted animals on walls of cave. But does it of them can be exactly what was it.

Using a combination of the tools which included the manganese pencils and clay which was coloured with various dyes, the first human ones left these images on the walls of a cave close to Lascaux, France and on cliffs in the Algerian Sahara.

Those were dated as being roughly 18.000 and 8.000 years respectively. Unfortunately, there is no manner of being sure exactly which message was communicated (a problem which our own descendants 15.000 years as of now can encounter very well of what we leave!)

Since the images depict the animals which were generally driven out then, and were given the importance of game to a drive out-supercilious culture, it 's possible that such images were attempts to present information on such a play, or part of a rite conceived to ensure a successful hunting.

The invention of the written forms - including/understanding pictograms such as hi�roglyphes, alphabetical writing and syllabic systems - seems to have taken place almost at the same time as the development of agriculture. Agriculture presented formerly unknown concepts such as the land property, the advanced trade and the accumulation of the richness, which has in their turn led to more complex social structures.

While you could envisage, this made necessary a record keeping more detailed and more effective. The alphabetical writing has a substantial advantage compared to the pictograms (hi�roglyphes), because a relatively limited number of symbols (letters) can be employed on several occasions in the infinite combination to communicate anything almost. (Because you will see later, modern I.T employs only two of these symbols!)

The safeguarding and the storage of such an information launched certain challenges; information had to be registered on the stone or the tablets of clay (which were heavy) or animal skins, compressed of wax or papyrus (which weren 'well of T).

The world hellenistic

The traditional Greeks were the first people of the disc to try to find explanations scientific and reasonable for normal phenomena. Some of the proto-computers earliest known were the mechanical devices developed by the Greeks. One of the latter was the shape of abacus (which developed also and was employed in ancient China). The facilitated device and simplified mathematical calculation.

Consider the abacus gr�co-Roman REALLY early

Another data-processing device early was will antikthera it, Greek of origin. One will antikthera was discovered by a Greek sponge plunger above there is one century, it was very recently that this 2100 year old device was rebuilt and shown to be the shape early of computer conceived to draw up a chart the movements of the sun, the moon and five planets known then.

Programmable devices early

Before the progressive dissolution and the fall of the Roman empire were complete in the year 476 E.C., scientific progresses and technological in the western world had stopped. While most of the scientific knowledge of the Greeks was preserved by the Irish monks and the Arab disciples, it wasn 't to the fourteenth century that principles of the technology were red�couverts and applied to information. The first of the latter was naturally the typographical press.

Although the concept of the mobile type impression was developed in China approximately four hundred years earlier, it was device of Gutenberg 'of S into 1447 which revolutionized communications, it making and more rapid easier to record and disseminate information that always front. The first truly programmable device would not come length during 354 more years, however.

The handle of Jacquard of 1801 was a product of the Industrial revolution. This invention employed a series of particularly perforated paper charts which functional like gauges, taking account of the automatic weaving of the strongly complex models. These charts of punch became very significant with calculation in the 1950 's, 60 's and 70 's.

The next development was Charles Babbage 's machine analytical - a full-programmable computer which unfortunately never was really built. Babbage worked on designs of 1837 until his passing in 1871. This steamer-actuated mechanism would have also used charts of punch, with a central processing unit of treatment (central processing unit of treatment) and a form of storage of memory in the form of system of the ankles inserted in the revolving barrels.

The analytical machine would have been able to store 1.000 numbers of to fifty digits each one, and carries out six different mathematical operations, including the calculation of the square roots. Babbage 'ideas of S were incorporated in the devices of electronic computation early being developed towards the end of 1930 's and 1940 's, although not all the latter was really programmable. The first truly programmable computers - able to store and the information of use - did not inherit everyday usage until the 1950 's, and yes - been useful charts of punch (these born before 1965 can remember to play with them).

Naturally the majority of the people born in the 70 's, 80 's and 90 's take just for grateful that the information technology which we have is today recent developments of fairley in science, mechanics and electronics. But we know that different now put 't us. And can thus better appreciate than we have available to us maintaining.
