Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data or information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. IT is considered to be a subset of information and communications technology (ICT). 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 radio.
IT has become an essential part of many businesses, with companies relying heavily on their IT systems to process customer orders, manage inventory levels, and create detailed reports. Modern day IT includes the use of virtualization, cloud computing, and storage area networks. Additionally, advancements in mobile computing technology have allowed people to access company networks from anywhere, anytime.
IT can also refer to the collection of tools, processes, and methodologies used to manage and protect information. As the amount of data gathered by organizations continues to grow, so does the need for effective data management. IT professionals are responsible for developing and implementing systems that securely store, access, and analyze data. This includes ensuring the safety of data stored in company networks, keeping track of user access rights, and using analytics to identify potential security threats.
IT is often associated with business processes such as customer relationship management (CRM) and Enterprise Resource Planning (ERP). These processes leverage the latest IT advances to make it easier for companies to reach their goals. Examples include the use of cloud computing and virtualization to increase server efficiency, utilizing enterprise mobility solutions to make it easier for employees to access company data on the go, and leveraging big data analytics to gain new insights into customers and markets. As technology continues to advance, IT will remain an important component in helping organizations remain competitive and success.
