The Top 10 Things You Need to Know About Information Technology: An Analysis of How Information Technology Can Improve Customer Service and The Bottom-line

This briefing on Information Technology was prepared by Raemel AJ Richardson while a Business Administration major in the College of Business at Southeastern Louisiana University.


Most companies have IT (information technology) departments for managing the computers, networks and other technical areas of their businesses. These jobs include computer programming, network administration, computer engineering, Web development, technical support and other related occupations. I am going to tell you about the history, advantages, and disadvantages of IT as well as its use in the health care industry and what’s to come.

The Idea in a Nutshell

Information Technology, or IT, refers to anything related to computing technology, such as networking, hardware, software, the Internet, or the people that work with these technologies. The modern term appeared in a 1958 article published in the Harvard Business Review by its authors, Leavitt and Whisler.

The Top 10 Things You Need to Know About Information Technology

1. Time Periods: IT is characterized by four basic periods: Pre-mechanical (3000 BC – 1450 AD), Mechanical (1450 – 1840), Electromechanical (1840 – 1940), and Electronic (1940 – Present).

2. ARPANET: The U.S. Department of Defense created the first adaptation of the Internet called ARPANET in the 1960s. It is an acronym for Advanced Research Project Agency NETwork. At the time, it was intended only for the government, research, university and scientific computers.

3. Computerization: The internet business processes have made many businesses turn to the Internet for increased productivity, greater profitability, clutter free working conditions and global clientele.

4. Networking: Not only are the company web sites good for networking but also sites like Facebook, LinkedIn and Twitter as well as blogs and forums. Social networking sites like these allow companies to share information and news updates quickly with their followers.

5. Job Elimination: As technology improves, tasks that were formerly performed by human employees are now carried out by computer systems. Automated telephone answering systems have replaced live receptionists in many organizations. This leads to the elimination of jobs and, in some cases, alienation of clients.

6. Security Breaches: Information technology systems are vulnerable to security breaches, particularly when they are accessible via the Internet. If appropriate measures are not in place, unauthorized individuals may access confidential data. Information may be altered, permanently destroyed or used for unpleasant purposes.

7. Health information technology: Health IT is the area of IT involving the design, development, creation, use and maintenance of information systems for the health-care industry.

8. Using HIT: Health IT may be useful for reducing paper work, reducing medical errors by misreading the doctors’ handwriting, and reducing health care cost by decreasing the need for repeat medical test by different doctors.

9. Future of HIT: Three important types of health IT may affect us in the near future as more consumers use personal health records (PHRs) and more physicians use electronic health records (EHRs) and electronic prescribing (e-Rx).

10. Job Outlooks: If you seek a career that offers plenty of intellectual stimulation, professional challenge and excellent earning potential, you need not look any further than Information Technology. Careers in Information Technology are “hot” and will continue to be in great demand well into the next century.
