Bcom refers to Bachelor of Commerce. There are two ways to pursue this course - distance mode and regular mode. In distance mode, as explained in this newbielink:https://distance.sgvu.org/bcom-syllabus-part_1.html [nonactive], you can learn from the comfort of your home without having to attend college or university on a regular basis. This option allows you to study while simultaneously holding down a job. However, if you opt for the regular mode, you must attend college on a regular basis and study there. Both methods are essentially the same, so it is your choice whether to choose Bcom online course or the regular course.
