Information and Communication Technology-Software and Hardware-The Applications of  Information Technology

Information and Communication Technology

  Information and communication technologies are all the bases, methods and steps used in communicating, disseminating information, and performing calculations using all electronic devices designed for this purpose, such as computers and various means of communication within established scientific rules and regulations.

The importance of Information and communication technology

 Information and communication technologies have greatly affected human life, Since the industrial revolution, man has begun to develop machines and equipment that facilitate his work. With the advent of information technology, mankind has jumped a qualitative leap towards development on the one hand and luxury on the other hand, where the work was done in the old offices using paperwork and transactions manually, which leads to taking a long time to finish, After the entry of technology into the world of business, agreements and transactions have been established from anywhere in the world and very quickly. Thus, ICT has a great impact on our lives,

On the educational side: boards, chalk, and heavy books were overloaded with a computer board containing all the educational courses, thus providing greater comfort to the student and introducing him to the world of development since childhood.
Some schools in the world have begun to teach the basics of programming languages as basic materials in schools, thus creating a scientific and cultural awareness of the student and making him an innovative person who makes the applications and devices he wants on his own.

On the industrial side: The entry of ICT after the industrial revolution led to the development of the machines used and linking them to the web to send orders to them from different sectors, which increased the productivity of industries and reduce the time required to achieve the desired goal.

In the political and military aspects: Information technology has played a major role in the power and dominance of the state. The major countries sought to develop means of communication and means of obtaining information about the enemy. The amount of information available became a serious weapon in which entire countries could be destroyed: radars, drones, Encrypted information is one of the fundamentals of military power in the state.

Definition of Information Technology

  Information technology (IT) is a broad discipline that deals with all aspects of technology, processing, and management of information, especially in large organizations, by dealing with computer software and electronic devices in order to transfer, store, protect, process, transmit and retrieve information.

Information technology (IT) has been divided into two sections:

Physical Section
The physical part is the devices used in the process of communication from computers and office and telephones to the wires used in the manufacture of networks that are connected with all devices to complete the transfer of information from one side to another.

Scientific section
  It is about programming languages, computational engineering, and artificial intelligence that manage the communication process according to steps determined by the administrator or engineer.

History of Information Technology

  Information technology emerged in the 1990s when computers became the basic tools at work at all levels and fields to meet the demands of everyday life, business activities in institutions, as well as with students. Therefore, professionals needed to develop technology and lay the foundations for their infrastructure.

Advantages of Information Technology

  • It Saves time, provides information, and then transfers it from the computer.
  • The individual gains skill thus enlarges his horizons and enhances his creative abilities.
  • It develops self-learning abilities in the individual.
  • The individual is given a sense of comfort when collecting information; it is a neat, organized, non-random technique.
  • The individual develops a method of solving problems that cannot be solved in traditional ways because of the large amount of information.
  • Perception of the individual is achieved because of computers used in information technology which provides the individual with the different data and appearances that he understands through his senses.
  • It allows the individual to be able to communicate any information he wants at any time through the Internet connection.

Characteristics of information technology

Accuracy: Accuracy is intended in terms of good quality information, and the corresponding amount of information.
Timing: It is the time period required to provide and retrieve information to the beneficiary.
Validity: means the appropriateness of information to the needs of the beneficiary.
Inclusiveness: It is intended to secure all aspects that the beneficiary needs.
Clarity: The information is far from ambiguity and unjustified confusion with other subjects.
Investigability: Advanced information can be examined, reviewed and investigated in terms of validity and time.

Applications of Information technology

The Applications of  Information technology

E-government: It is intended to manage transactions and public services provided to citizens in the state in electronic form, by using computers instead of using traditional methods such as paper or moving from one department to another.
E-Learning: By providing electronic content to the learner on the most accessible routes and using modern electronic media such as computers.
E-commerce: An information technology application that benefits companies through profit and access to markets on a large scale, and benefits the consumer in terms of providing services and goods, and accessibility.
E-Health: by providing specialist sites in various branches of medicine, providing medical consultations without going to the doctor's office, and providing information on various diseases.

 Jobs in Information technology

There are many job posting sites that use IT as a category in their databases, which includes a wide range of jobs including architecture, management, and engineering. People in such jobs typically have university degrees in computer science, information systems, Too short training courses on the basics of information technology in the Internet, which are useful for people who want to gain some fame in this area before working as a professional, IT schools can work in IT departments, or lead a team Ware product, or a group of researchers, and requires success in this area of work a set of technical and business skills.

Scope and extent of information technology

Film thumbnails are concerned with the reproduction of information for publication and storage known as a reproduction of recorded forms.
Computer applications used in many libraries, information centers and documentation, which rely on word processing, words, and databases.
Remote communication applications depend on the transfer of shapes and sounds.

IT software and hardware

 IT consists of several parts of the physical equipment: hardware, virtualization tools, automation, operating systems and applications used to perform basic functions. User devices, peripherals, and software, such as laptops, smartphones, and Information technology can also refer to methodologies and regulations governing the use and storage of data. Business applications include databases, transaction systems such as real-time order entry, e-mail servers, and web servers, CRM, and ERP systems. These applications implement the instructions programmed to process, integrate, scatter, or may affect other data for business purposes.

Computer servers manage business applications where servers interact with the client and other servers across one or more networks, and storage can be defined as any type of technology that saves information as data: Information on any form such as file data, multimedia, web data, telephone data, and data from sensors or future designs. Storage also includes variable RAM, non-volatile tape, hard drive, and hard disk drives. IT architecture has evolved to include virtualization and computing Cloud, where abbreviated physical resources, and assembled in different structures to meet the requirements of the application.
