Describe the role and importance of information technology in our society

The role and importance of information technology in our society is as follows:
1. Business: With the introduction of computers, the business world was changed forever. Using computers and software, businesses use information technology to ensure that their departments run smoothly. They use information technology in a number of different departments including human resources, finance, manufacturing, and security.
2. Education: Using technology, teachers can prepare their students for a future flooded with gadgets including tablets, mobile phones, computers, and so much more. Information technology is helping to prevent more high school and college dropouts as well.
3. Finance: 
Without information technology, online purchases would be impossible, and it would be impossible for banks to keep these purchases secure. Information technology has also made it faster and easier than ever to send or receive money.
4. Healthcare: 
Improvements in information technology have allowed for great reform in healthcare. Most medical offices can now send and receive digital medical information from doctors youve had in the past. Changes like this allow costs to be lowered and increase the amount of time doctors can spend on patients compared to paperwork.
5. Security: With so many transactions done online and so much information available online, its important to keep all of that safe. Information technology makes it possible for your online data to stay secure until accessed by the proper channels. Using passwords and encryption, information technology hides your personal digital data away, and the only way it can be accessed is by companies who have permission from you.
6. Communication: With improvements in information technology, globalization has increased. The world is brought closer, and the worlds economy is quickly becoming a single interdependent system. Information can be shared quickly and easily from all over the glob, and barriers of linguistic and geographic boundaries can be torn down as people share ideas and information with each other.
7. Employment: 
Information technology has also created new jobs. Programmers, systems analyzers, hardware and software developers, and web designers all owe their jobs to information technology. Without such advances, these jobs would not exist.
