The world has moved from the market age into data age. The whole world now depends on information, education as an institute is not an irregularity to this particular fact. The world has witnessed an data revolution, a compound of immense growth in the world's catalogue of data and the technical development of the means of processing and transmitting information
Computers are at the center of data technology. data is what computers process, forward and store. We use computers to create, manipulate, and administrate data faster and more precisely than with any ideas previously devised. So, good you understand computers and what they can and cannot so, the more power you will have to put data to work for you. Knowledge is power!
But data technology does not only involve computers. It also includes the way computer and communications technologies are combined, the follow is "Information Technology" - Infotech - technology that merges computing with telecommunication links carrying data, sound, and video. Therefore, there are two parts to data technology- computers and communications.
Moreover, data technology (It) as it is defined by the Longman Dictionary of modern English as the study or use of electronic processor for storing data and manufacture it available; data Technology. In addition to, before I forge ahead in relating it to the issue of Nigerian education system, I still have to put into notice the second conception of data technology. That conception is the transportation technology.
Communications Technology:
This is the technology that is used to reveal (digital) data. Data communication, often called telecommunication, means transmitting data and data electronically from one point to an additional one using the telephone, radio and microwave transmission devices, laser beams, optic fiber cables and direct wiring.
Computers can be standalone machines, unconnected to whatever else. If all you are doing is word processing to write term paper; that may be fine. The communications component of the computer ideas vastly extends the range of Pcs. Data transportation provides data processing services throughout the office on the around the world.
Again; to be able to understand the conception of data technology, you need to be aware of how computers work. There are three key concepts that form the basis of computer operation:
First: The purpose of a computer is to process data into information. Data consists of the raw facts and figures that are processed into data for example, the votes for dissimilar candidates being elected to pupil government office. data is data that has been summarize or otherwise manipulated for use in decision-making for example, the total votes for each candidate, which are used to conclude who won.
Second: You should know the difference between hardware and software. Hardware consists of all the machinery and tool in a computer system. The hardware includes among other devices, the keyboard, the screen, the printer and the "box"-the computer or processing device itself.
Software, or programs; consists of all the instructions that tell the computer how to perform a task. These instructions come from a software developer in a form (such as a Cd-Rom disk) that will be acceptable by the computer. Examples you may have heard of are Microsoft windows 98 or office 2000.
Third: regardless of type and size, all computers follow the same basic operations:
(1) Input,
(2) Processing,
(3) warehouse and
(4) Output.
