By the early twenty-first century, advances in technology had changed the world. The Internet had opened up various opportunities to people, transforming the workforce. By this time, thirty percent of the U.S. workforce was working in careers in information technology engineering. In fact, there were 136.9 million people worldwide who were connected to the internet at one time, equivalent to fifty-one million households. New types of technologies were introduced throughout the world, making processes more efficient. In addition, regulations were enacted requiring that the technology used be compliant with privacy regulations.
The job of an IT engineer is varied, from designing systems to integrating software and hardware. Some IT engineers may also have backgrounds in engineering, working in software development or hardware integration. While other IT professionals may work in information technology, they typically work in an area where they need to ensure the security of a company’s database and systems. They may also oversee the creation of training programs for company IT staff, perform usability tests, or upgrade existing systems.
In today’s world, businesses rely on software applications to perform their work. While some applications are procured from third parties, such as email servers, most organizations have their own staff of software developers who design applications and user interfaces for the systems they use. Developers can code applications in any of the many popular languages, integrating them with other applications. Developers may also be assigned a wide range of other tasks, such as creating interactive business websites or building mobile applications.
