Why is important to study technology?

Technology Today

Every day, more and more people study Computer Science to learn how to create innovative apps for cell phones and programs for computers that make our lives easier

Even if you don't like technology, we depend on technological advances such as computers, mobile phones, software and networks to store, process, transmit, retrieve and manipulate information in any professional area

A World of Computers
