What is Information Technology?

The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Information technology (IT) is the use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, store, secure and exchange all forms of electronic data. Typically, IT is used in the context of enterprise operations as opposed to personal or entertainment technologies. The commercial use of IT encompasses both computer technology and telephony. The term information technology was coined by the Harvard Business Review, in order to make a distinction between purpose-built machines designed to perform a limited scope of functions and general-purpose computing machines that could be programmed for various tasks. As the IT industry evolved from the mid-20th century, it encompassed transistors and integrated circuits — computing capability advanced while device cost and energy consumption fell lower, a cycle that continues today when new technologies emerge.

IT software and hardware; • IT includes several layers of physical equipment (hardware), virtualization and management or automation tools, operating systems and applications (software) used to perform essential functions. User devices, peripherals and software, such as laptops, smartphones or even recording equipment, can be included in the IT domain.
• IT can also refer to the architectures, methodologies and regulations governing the use and storage of data.
• Business applications include databases like SQL Server, transactional systems such as real-time order entry, email servers like Exchange, Web servers like Apache, customer relationship management and enterprise resource planning systems. These applications execute programmed instructions to manipulate, consolidate, disperse or otherwise affect data for a business purpose.
 • Computer servers run business applications.
 • Servers interact with client users and other servers across one or more business networks.
 • Storage is any kind of technology that holds information as data. Information can take any form including file data, multimedia, telephony data and Web data, data from sensors or future formats. Storage includes volatile random access memory (RAM) as well as non-volatile tape, hard disk and solid-state flash drives.
 • IT architectures have evolved to include virtualization and cloud computing, where physical resources are abstracted and pooled in different configurations to meet application requirements. Clouds may be distributed across locations and shared with other IT users, or contained within a corporate data center, or some combination of both deployments. IT Uses; Is any computer-based tool that people use to work with information and support the information and information-processing need of an organization. These tools can include computers, software, routers, severs, printers, modems, just to name a few. Businesses will increase their efficiency when they embrace Information Technology. The main goal of a business is to serve its customers. In this age of information technology, a business can gain competitive advantage when it uses information technology to its maximum. Today perfect service is only possible if a business has the right information in the hands of the right people at the right time and this can only occur through appropriate use of information technology. This means that the challenge facing any business is to plan for develop, manage, and use its three most important resources i.e. information, information technology and people – to provide perfect service to its customers. Below are listed a few uses of information technology both in our society and in business.
