Number PART ONE: INFORMATION TECHNOLOGY (IT) ## One. What is Information Technology?

Information Technology (IT) is the use of computers, software, networks, and systems to store, process, manage, and protect data.

In simple words, IT is the use of technology to handle information.

For example, when you use a laptop to make an assignment, send files through Gmail, or save documents in Google Drive, you are using IT.

IT is not only about computers. It also includes smartphones, applications, internet networks, cybersecurity, and business systems.

### Primary Purpose of IT

For example, a school has many students and needs to keep their grades and records. If everything is written on paper, it may take a long time to find information. With a computer system, the school can save, update, and find student records more easily.
