Information technologies (ITs) are computer and telecommunications equipment that allow us to exchange, store and process information. They include the software and hardware that enable us to communicate with others through instant messaging or e-mail, keep track of investments using online banking or spreadsheets, pursue hobbies like genealogy or gardening with specialized graphing or word processing software, find medical information or search for jobs or schools through the World Wide Web, and much more.

The technology allows people to quickly access and organize huge quantities of data, which results in greater efficiency. It also gives access into immense quantities of data that can be analyzed and enables the making of decisions in a much faster manner than was previously possible.

Information technology is becoming more vital to the world of business. It can help companies control employee attendance and time as well as automate tasks that required manual effort or human intervention, streamlining operations and increase productivity. It can also enable companies to monitor inventory levels or provide 24/7 customer support.

Users are often required to learn new technologies in the field at a rapid pace. A lot of IT jobs are focused on the development, maintenance and support of these systems. Information security analysts manage computer support specialists, cybersecurity provide technical assistance to users and network administrators create and maintain communications networks, such as networks and LANs.
