Hackers communicate with one another through computer networks. Before Internet access was widespread, hackers would communicate via electronic bulletin board systems (BBS) that they set up to share information and download programs. Now there are Web sites specifically for hackers, such as the one hosted by a journal called "2600: The Hacker Quarterly." This Web site has a live broadcast section for hacker topics. Meanwhile, Hacker.org has puzzles and contests for hackers to sharpen their skills.
