(2) (MB) (MotherBoard) On references to basic hardware components, MB often means motherboard or mainboard.
(3) (Mb) (MegaBit) One million bits (1,000,000 bits or 1,048,576 bits). In communications, mega typically refers to 1,000,000. In storage, mega typically refers to 1,048,576. Lower case "b" for bit and "B" for byte are not always followed and often misprinted. Thus, Mb may refer to megabyte. See mega and space/time.

Back in the 1970s, all 11 of these 14" platters held a total of 100 megabytes. Today, that much platter space would hold more than two million times as much. (Image courtesy of The Computer History Museum.)
