Fluency with information technology (shortened as FITness) goes beyond traditional notions of computer literacy.Literacy about information technology might call for a minimal level of familiarity with technological tools like word processors，e-mail，and Web browsers.By contrast，FITness requires that persons understand information technology broadly enough to be able to apply it productively at work and in their everyday lives，to recognize when information technology would assist or impede the achievement of a goal，and to continually adapt to the changes in and advancement of information technology.FITness therefore requires a deeper，more essential understanding and mastery of information technology for information processing，communication，and problem solving than does computer literacy as traditionally defined.Note also that FITness builds on many other fundamental competencies，such as logical reasoning and knowledge of society.
Information technology is a medium that permits the expression of a vast array of information，ideas，concepts，and messages，and FITness is about effectively exploiting that expressive power.FITness enables a person to accomplish a variety of different tasks using information technology and to develop different ways of accomplishing a given task.
FITness comes in degrees and gradations and is tied to different purposes.FITness is thus not an“end state”。but rather develops over a lifetime in particular domains of interest involving particular applications.Aspects of FITness can be developed by using spreadsheets for personal or professional budgeting，desktop publishing tools to create or edit documents or Web pages，search engines and database management tools for locating information on the Web or in large databases，and design tools to create visualizations in various scientific and engineering disciplines.
The wide variety of contexts in which FITness is relevant is matched by the rapid pace at which information technology evolves.Most professionals today require constant upgrading of technological skills as new tools become useful in their work;they learn new word processing programs，new computer-assisted design environments，or new techniques for searching the World Wide Web.Different applications of information technology emerge rather frequently，both in areas with long traditions of using information and information technology and in areas that are not usually seen as being technology-intensive.Perhaps the major challenge for individuals embarking on the goal of lifelong FITness involves deciding when to learn a new tool，when to change to a new technology，when to devote energy to increasing technological competency，and when to allocate time to other professional activities.
The above comments suggest that FITness is personal，graduated，and dynamic.FITness is personal in the sense that individuals evaluate，distinguish，learn，and use new information technology as appropriate to their own sustained personal and professional activities.What is appropriate for an individual depends on the particular applications，activities，and opportunities for FITness that are associated with the individual‘s area of interest or specialization，and what is reasonable for a FIT lawyer or a historian to know and be able to do may well differ from what is required for a FIT scientist or engineer.FITness is graduated in the sense that it is characterized by different levels of sophistication，and it is dynamic in that it requires lifelong learning as information technology evolves.
