This paper discussed the concept of computer competency and investigated the relationship between students' computer competency and their perception of enjoyment and difficulty level of web-based distance-learning courses. Participants were 237 entering graduate students in library and information science from a mid-southwestern state university in the United States from year 2001 to 2003. Computer competency was estimated by students' self-report of their prior knowledge of information technology skills in a survey called "Computer Skill and Use Assessment". Statistical significance was found between the correlation of computer competency and students' perception of enjoyment level (p=0.011) and difficulty level (p=0.001). (Contains 4 tables.)
