The importance of information technology

the information

 A person needs to know what is going on around him to infer solutions to all issues, and this can only be done by removing suspicion, with information that is an intrinsic and external definition of any entity or object, where the information represents everything known about it, and the information is related to data that are values ​​attributed to the information, as well as linked to various Domains, such as knowledge that refers to knowledge of the concrete and abstract concept of any object, communication agencies as they express the content of messages, notes, and signals sent and received, and are also related to security, privacy, and other fields, and this information is expressed in the form of a series of characters that suspect For a set of words and symbols understood, everything is built, preserved and processed by entering information for special devices, and in this article the importance of information technology will be clarified.

information technology

 After the concept of information has been clarified, it is necessary to know how to process and store this information, and know the importance of information technology, so the use of some computer devices and others in storing, processing information and extracting and manipulating data is called information technology, which is a very important technology, and it is a branch of the world of information and communication technology, Information technology is usually denoted by IT, a technology that has existed since ancient times for its necessity for humans. People have stored, retrieved and processed information since ancient times.

 Information technology has gone through several stages that are different from each other in the development and method of data processing. In the first stages, the Sumerians in 3000 BC collected information and stored it on stone or clay tablets, and this stage continued until 1450 AD, and this stage is called the pre-mechanical stage. The second stage is represented in the Middle Ages from 1450 to 1840 AD, where mechanics were used to processing and store information, and with the discovery of electricity, humans used electricity and mechanics to store and process information called this electromechanical stage, which is from 1840 AD to 1940 AD, where technology developed Information widely with the technological development that has occurred and emerged information technology known today, but the information technology term appeared only in 1958.

 Information technology includes many devices that collect information, store, process, and transfer information, and it represents every device capable of receiving information and data and processing it, such as computers and networks and everything related to it, even displays, televisions, phones and many more, thanks to the rapid technological development.

PC

  Computers are spread all over the world and are responsible for performing all operations of companies and users, as companies depend on the use of distributed computers in addition to a data and information center that branches to a number of sub-computers, and computers have a set of input and output devices for users and companies, such as printers and scanners, And these devices are developed every year to improve and speed up the treatment process.

computer programs

  Computer programs are divided into two parts, the system program which is responsible for operating and managing internal computers and receiving and processing information within the computer's processing unit, and application programs, which is the graphical interface that appears to the user to identify information, manipulate data and retrieve it, and to facilitate the user's interaction with computers.

wired and wireless communication

 In most companies a large server is built and all the subsidiary's devices are linked to each other by wired connections, in order to facilitate the process of transferring and managing information in the company, and the external network is connected via wireless connections to receive and send information, and global networks and the Internet are designed to exchange data And connect all the devices of the world together.

 Databases

 It is a set of data that has been processed and stored in an organized manner or in the form of individual records, it can be retrieved to meet the user's need of it, and information technology is worked through, where the entered information is processed and then stored within the scope of the database, and many rules were developed to become Faster to receive and send information.

The importance of information technology

 The importance of information technology stems from the urgent need for it in the era of technological development and speed, which requires high-speed, accurate and reliable processing of information.

Work and society

 Information technology has led to a fundamental change in the concept of cooperation and exchange between the parties of society, and between companies and clients and contributed to saving a lot of time in data processing, storage and analysis, where some information technology devices work to address some of the things that need thousands of years of human and manual work, in A few seconds, it gives reliable and accurate results.
