    The cable that connects my digital camera to my computer has a "lump" or "thing" built into it. About 1 inch long and 1/2 inch diameter. What is its purpose?

    Question #117214. Asked by serpa. (Sep 01 10 1:09 AM)

    		It is (the housing for) a "ferrite bead."

    "A ferrite bead is a passive electric component used to suppress high frequency noise in electronic circuits....Ferrite beads are one of the simplest and least expensive types of interference filters to install on preexisting electronic cabling. For a simple ferrite ring, the wire is simply wrapped around the core through the center typically 5 or 7 times."
