Information Technology
Information Technology refers to the technology for collecting information. Systematic storage, Fast data retrieval, processing, and analysis of the results of the processing. Including an emphasis on displaying and publicizing that information effectively in a format suitable for those who will continue to use it.
Information Technology or IT is the application of computers and telecommunications equipment to store, search, transmit, and process information often associated with one business or other organization. Usually used to represent computers and computer networks. It also includes other information distribution technologies such as televisions and telephones. Many industries are related to information technology. For Example hardware, software, and electronics. semiconductor internet telecommunication equipment electronic commerce and computer services.
Humans have been known to collect, retrieve, process, and communicate information since the Mesopotamian period by the Sumerians around 3000 BC, but the term in its meaning modern appeared in 1958 in the publication Harvard Business Review, written by Thomas L. Whistler, commenting that “New technology doesn’t yet have a name that’s set up as a single thing. we will call it Information Technology (IT)”.
The definition of this term includes three types of technologies: processing techniques; application of statistical and mathematical methods for decision making and simulating ideas at a higher level through computer programs.= The development of information technology can be divided into four eras. The storage and processing technologies used, they were Pre-Mechanical (3000 BC – 1450 AD), Mechanical (1450–1840), Electromechanical (1840–1940), and Electronic Age. (1940–present). This article will focus on the latest era. (electronic era) which began around the 1940s.
History of computer technology
Devices have been used to aid calculations for thousands of years, presumably in the form of sticks or tio to record counts . The Antikythera mechanism dates from the beginning of the first century BC. BC is generally considered to be The oldest known mechanical analog computer. and the earliest known geared mechanism. Comparable geared devices do not occur in Europe until the 16th century and it wasn’t until 1645 that the first mechanical calculator capable of performing four basic arithmetic operations was developed.
Electronic computers that use relays or valves Beginning to appear in the early 1940s, the electromechanical Zuse Z3, completed in 1941, was the world’s first programmable computer. and according to modern standards One of the first machines that could be considered a complete computer, the Colossus, developed during World War II to decode German texts, was the first electronic digital computer. Although it is programmable It was not used for general purposes.
It is designed to perform only one task. It also lacks the ability to store programs in memory. programming This can be done by using plugs and switches to change the internal wiring. The first recognizable modern electronic digital stored-program computer was the Manchester Small-Scale Experimental Machine (SSEM), which launched its first program on 21 June 1948.
The development of transistors in the late 1940s at Bell Laboratories resulted in significantly reduced power consumption for modern designed computers. The first commercially available stored programmable computer, the Ferranti Mark I, consisted of 4,050 valves and had a power consumption of 25 kW. Launched in November 1953, it consumed only 150 watts of power in its final version.
Information technology infrastructure It is an integrated framework under which digital networks work. This infrastructure includes data centers, computers, computer networks, database management devices and governance systems. In information technology and on the Internet Infrastructure is physical hardware that is used to connect multiple computers and users. The infrastructure consists of the transmission medium, including telephone lines, TV cables, satellites, and antennas, and there are also several routers that are used to transfer data between different transmission technologies.
In use sometimes Infrastructure means connecting hardware to software. And does not communicate with computers and other connected devices. However, for some users of information technology. Infrastructure is seen as everything that supports the flow and processing of information.
Infrastructure companies play an important role in the development of the Internet. They influence where there must be a link, where the data must be made accessible, and how much information can be processed and done quickly.
