Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures that underlie the acquisition, representation, processing, storage, communication of, and access to information.

The rewards of taking this course are immense. In addition to being a subject in itself, computer science can be applied to almost any other discipline from accounting to zoology. The job prospects for computer scientists and computer engineers are excellent.

Be patient in your studies, and don't get too frustrated if you are stuck on one part of a programming assignment or confused about a concept. Struggling with the materials is a normal and essential part of the learning process. You're probably better off going through the course sequentially and consulting external references as needed.

Each lesson, particularly in the programming component of the course, builds on previous sections and it is best to keep up with the materials throughout. You're welcome to go at your own pace and begin or end at any time.

Information technology (IT) is the application of computers to store, study, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered a subset of information and communications technology (ICT).
