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
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:
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.
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.
