About The Information Technology


It is the use of any computers, storage, networks, other physical devices, infrastructure, and processes to create, process, store, secure and exchange all forms of electronic data.
It is usually used in the context of enterprise operations versus personal or recreational user techniques, while commercial use of it encompasses both computer technology and telephones.

The term Information Technology (IT) was first formulated and presented in the Harvard Business Review, in 1958, in order to differentiate between machines built for a particular purpose, designed to perform a limited range of functions, and general-purpose computing machines, which can be programmed For different tasks.

Information Technology Tools
Information technology uses hardware and software tools to perform its functions; Hardware tools include physical hardware such as laptops, tablets, mobile phones, audio recording devices, and more, while software includes operating systems and virtual processes To implement core functions. The information technology area also includes the structures, methods and rules relating to the use and application of electronic data.

Business applications.
  • Database servers, which are the computer programs that provide the database service to other devices.
  • E-mail servers, an application that receives e-mail messages and forwards outgoing messages to senders.
  • Web servers are computers that provide Web pages, and servers interact with client users across business networks.
  • Storage; It is any type of technology that contains information as data, and information can take any form, including file data, multimedia, telephone data, web data, and data from sensors, and includes the concept of temporary storage; such as memory Random access (RAM), permanent, such as hard drives, and flash memory.
Data in Information technology
Electronic data processing in information technology includes data storage, retrieval, transmission and processing.

Data storage
Technological innovations have made the process of storing data easier and easier, and can be stored in hard drives, optical devices, or magnetic tapes.
With the increase in the amount of data, storage problems, and the possibility of retrieval or access have arisen. In the 1960s, the database management system was introduced to address this issue, as these systems allow access to stored data, simultaneously, by many users, and without loss of integrity.

Data retrieval capability
What it means to get data from database management systems.

Here, it should be noted that the terms of data and information are not synonymous as suggested to some; the word data can be released on anything stored, but to be presented as information, it must be organized, and if in any case the data is actually represented in an orderly way, this does not indicate any But regarding the previous terminology, in general, most of the available digital data is not regulated.
Data Warehouses are being developed in the 1980s and contain data from various sources, including external sources such as the Internet.

Data Transfer (Transmission)
This concept can be divided into three aspects: propagation, transmission, reception, and, in general, it can be classified into the two-way broadcasting and bi-directional communications areas.

Manipulation and modification of data Manipulation
Is the process of changing data in an attempt to make it easier to read; a huge amount of data is stored around the world every day, but unless it is analyzed and effectively removed, it is not useful, and the data Mining concept was developed in the 1980s to address this particular issue.

Recent trends in Information technology
With the development and general change in technology, information technology and trends are changing as well, and some current trends can be monitored through:

Cloud computing (Cloud Computing)
Is Internet-based computing, which provides shared data for computers and other devices as required.

Cloud computing reduces the cost of IT infrastructure in the company, and enhances the concept of virtualization, which enables the use of the server and storage device across the enterprise, as well as the maintenance of software and hardware easier using cloud technology.

Mobile phone apps
These applications have been a tremendous success since their inception and even today, perhaps the most important characteristic is the possibility of downloading them from the Internet.

User interface
The user interface revolutionized after the advent of touch screens, which enabled the user to interact directly with the projector, thus avoiding any intermediary device. This trend is mostly used with smart phones, tablets, and more.

A set of statistics, and operations research, helps in discovering data patterns in the information.

Information technology-related jobs and professions

It teams rely on a wide range of skills, knowledge, information, and specialized technology to support equipment, applications, and activities.

The information technology professions are very diverse; their employees can specialize in areas such as software development, application management, desktop, server, storage and network infrastructure, and many companies seek to attract IT professionals with skill sets Mixed or nested.
  • The Chief information Officer is responsible for information technology and computer systems that support the organization's objectives.
  • Technical Officer (Chief Technology Officer): This person places all technical objectives and policies within the organization.
  • Information Technology Manager (IT Director): Responsible for the functionality of all the technical tools and processes of the business, this role is called it Manager (IT manager), or the information technology (IT) leader (it leader).
  • System administrator (Systems Administrator): This person configures, manages, supports, troubleshoot, and repairs the multi-user computing environment. Within the enterprise, this role can be divided by technology, which requires a supervisor or team dedicated to the server, desktop, network, default representation, or any other component.
  • Application Manager: This person's role focuses on providing and managing a high-value business application, such as Exchange.
  • Developer: writes, updates, and tests software-specific codes, whether to meet business objectives internally, or those that customers are looking for.
  • Architect (Architect): This person examines and changes the information technology functions to support the business in the best manner.
