This site is composed of hundreds of information technology tutorials that span everything from hardware operation to common office software to software development tools. The tutorials that deal with programming languages and networking tend to be geared more toward specific functions and concepts rather than all-encompassing overviews of the entire subject, while those that address less technical software applications generally have an orientation to the fundamentals. A particularly helpful inclusion in many of the tutorials is a number of screenshots, which illustrate how to access properties and settings within certain applications. Several resources for different kinds of certification are available.
