Information Technology is a modern era derivative of Information Sciences. For centuries, ever since the invention of writing methods, the human race has stored information to be retrieved, studied by others and also for inter personal transmission and propagation. Information Technology is only a modern age of doing the same. However, though it might not be entirely novel, it certainly is different from its predecessors. It is the method of storage, study, retrieval and transfer of data using the electronic computing devices of the modern era. The right programs and algorithms that drive this method of storage of information are essentially based on a highly specialized form of mathematics, known as binary mathematics.This genre of mathematics needs to be learnt with particular focus if one is to master the art of writing programs and algorithms for different purposes. And, especially in the post-millennial era, computers and computing devices have assumed such a degree of sheer importance in the lives of an overwhelming amount of global population that learning Information Technology and acquiring expertize in IT support services have become both popular and necessary. Educational Institutions and Universities the world over offer a variety of academic programmes geared specifically to teaching of Information Technology.
Information Technology is looked upon as either an applied Engineering subject or as a theoretical Scientific subject. Institutes and Universities offer it as a stand-alone field or as a specialized part of an allied field. Of course, given that it is wholly based upon computing devices, the most common allied subject that it is paired with is Computer Sciences. Besides this, some of the other popular allied fields are Information Sciences, Communication Sciences, Information Systems, Telecommunications, Electronics, Informatics, Decision Sciences, Mathematics, Statistics, Relational Algebra and Data Modelling. Some, for example, Information Science and Systems, Electronics and Telecommunications, look at Information Technology more from an applied Engineering angle. Fields, like Mathematics and Statistics, take on a more theoretical Basic Sciences approach. Again, fields, like Decision Sciences or Informatics, assume a theoretical Applied Sciences approach. However, whatever be the approach adopted, each one imparts knowledge and expertize in IT support to its students.
Mainstream full-time Bachelors and Masters are offered in Information Technology, either as a stand-alone field or as a specialized one, in most Institutes and Universities. Part-time programmes are equally popular. There also are offered Diploma and Certificate courses of shorter duration for people requiring a shorter route to basic competence. People that are unable to attend classes, Distance Learning courses are also an available option. Those wishing to pursue research have the opportunity of doing a Doctoral degree in the field as well.
