What is Information Technology (IT)?
The use of computers, storage, networking, and other physical equipment, infrastructure, and procedures to produce, process, store, protect, and share all types of electronic data is referred to as information technology (IT). IT is often utilized in the context of commercial operations, as opposed to personal or leisure technology. IT for business includes both computer technology and telecoms.
The term information technology was created by the Harvard Business Review to distinguish between purpose-built machines meant to execute a restricted set of duties and general-purpose computing devices that could be configured to accomplish a variety of jobs. Computing capability expanded as the IT sector evolved beginning in the mid-20th century, but device cost and energy usage declined, a cycle that continues now as new technologies arise.
Information Technology Definition

| Definition Of Information Technology |
The term "information technology" first appeared in a 1958 article in the Harvard Business Review (HBR). Several categories of information technology were defined by authors Harold J. Leavitt and Thomas L. Whistler:
Using statistical and mathematical models to make decisions"
The "computer-based simulation of higher-order thinking"
"While many features of this technology remain unknown, it is evident that it will swiftly enter the managerial scene, with significant and far-reaching implications for managerial organization," they stated.
Six decades later, it's evident that Leavitt and Whisper had a good idea. Today, information technology encompasses everything that organizations do with computers. Building communication networks for a company, safeguarding data and information, creating and administering databases, assisting employees with computer or mobile device problems, or performing a variety of other tasks to ensure the efficiency and security of business information systems are all examples of information technology.
Examples of information technology
So, how does IT fit into day-to-day operations? Consider the following five frequent instances of IT and teamwork:
Upgrade of the server: A data center server or servers nearing the end of its operational and maintenance lifetime. IT staff will choose and purchase replacement servers, setup and deploy this same new servers, rollback apps and information on existing servers, transition that information and software to the new servers, substantiate that the new servers are operational, and then repurpose or dismantle and try to get rid of the old servers.
Security surveillance: Businesses routinely use software to track and log activity in applications, networks, and systems. When IT staff receives alerts of potential threats or noncompliant behavior – such as a user attempting to access a restricted file – they check logs and other reporting capabilities to start investigating and examine the root cause of the warning system and take immediate actions to address and rectify the threat, often driving changes and enhancements to nation's security that can prevent similar events from occurring in the future.
Business development: A vital application must be more available to a firm in order to aid with revenue or business continuity initiatives. IT employees may be asked to design a high-availability cluster to provide increased performance and resilience for the application, ensuring that it can continue to function in the face of single outages. This can be used with improvements to data storage security and recovery.
Brand new software: The company concludes that a new mobile application is required to allow users to log in and view account information or complete other transactions via smartphones and tablets. Developers labor to design and improve a suitable application in accordance with a roadmap. Each iteration of the new mobile application is made available for download by operations employees, who also deploy the app's back-end components to the organization's infrastructure.
User assistance: Developers are working on a significant update to a critical business programme. Developers and administrators will work together to generate updated upgrade documentation. IT personnel may deploy the update for restricted beta testing, enabling a chosen number of users to trial the new version, while also preparing and delivering complete training that prepare all users for the final release of the new version.

Information technology a relatively new term
The phrase "information technology" has been in use since 1958, according to the Online Etymology Dictionary. It was initially published in the Harvard Business Review. The study of the origins of words and how their meanings have developed is known as etymology.
In a Harvard Business Review paper published in 1958, Harold J. Leavitt and Thomas L. Whisper stated:
"There is no one accepted term for the new technology. We'll refer to it as information technology. It is made up of multiple interconnected sections.”
