The purposes of this research were to study and compare the knowledge on computer law of bachelor’s degree students of 3 departments in Faculty of Industrial Education King Mongkut’s Institute of Technology Ladkrabang (KMITL). The research method was descriptive research. The sample of 257 students were selected by using stratified random sampling method. The research tool was the multiple choices test which consisted of 30 items which validated by experts. the difficulty value (p) were 23 - 77 the discrimination power value (r) were 20 - 80 and the KR 20 reliability was .75. The data were collected in the 2008 academic year then analysed by mean percentage (%) and one-way analysis of variance (F-test). The findings were 1) The knowledge on computer law of students were at low level as overall (31.80%) and each department (30.60%-32.87%) 2) The knowledge on computer law of students was not different among 3 departments at .05 significant level.
