Around one hundred and fifty years ago, businesses ran their day to day operations completely different from what businesses of the modern era do to run their day to day operations. People back then worked under candle light doing math calculations on paper, the old fashion way, before electricity came about in the early 20th century. Now, most of the civilized world wouldn't know what to do with themselves without technology. Imagine not even having a calculator for math or the internet to do research. Yes, I know, it is hard to believe people were able to survive without these advanced tools that we take for granted each day. The advances in communication combined with the evolution of the IT industry has made it possible for people to do business throughout the world in real time. Improvements in IT improve our lifestyles and business by allowing computers to reduce complications and enrich possibilities.
These days, the name "Information Technology" has managed to encompass many aspects of computer technologies invented in the past couple decades. These IT spectrums can be covered in many types of professional fields such as Management Information Systems, Computer Networking, and Software Design. Our ancestors couldn't even fathom what our society has accomplished.
In medicine, Information Technology also plays a substantial roll. Doctors take pictures with machines like a computerized axial tomography (CAT) or magnetic resonance imaging (MRI) and can print out three dimensional images of bones, muscles, and organs. These images can help map out patient's problems and help save lives. This day and age, it is difficult to find a field or industry that IT has not been greatly affected.
IT is completely responsible for how organized our civilization has become. The corporate world was only made possible by the communication information technology has put in place between both computer software and hardware. From a personal stand point, it would be difficult for most people to name a single person doesn't use the internet on a regular basis.
With the increasing new technologies coming out everyday, employees in the Information Technology work force must constantly re-educate themselves with all the new technologies. This makes IT a very demanding field as it is always developing and perfecting. The process of improvement is what makes this such a desirable aspect to almost any business. It is very important for anyone in the IT field to always stay up to date with all newly developing technologies that relate to their industry. IT is now the complete backbone to almost any business and its ability to be competitive and efficient.
