Personal Area Network (PAN)

A personal area network (PAN) is a computer network for interconnecting electronic devices within an individual person's workspace.[1] A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway.

A PAN may be wireless or carried over wired interfaces such as USB. A wireless personal area network (WPAN) is a PAN carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth or ZigBee. The reach of a WPAN varies from a few centimeters to a few meters.

10 Facts You Didn't Know About Computer Hacking :-

1. Hacker originally meant “one who makes furniture with an
ax.”
Perhaps because of the blunt nature of that approach, the word came to mean someone who takes pleasure in an unconventional solution to a technical obstacle.

2 Computer hacking was born in the late 1950s, when members of MIT’s Tech Model Railroad Club, obsessed with electric switching, began preparing punch cards to control an IBM 704 mainframe.

3. One of the club’s early programs: code that illuminated lights on the mainframe’s console, making it look like a ball was zipping from left to right, then right to left with the flip of a switch. Voilà: computer Ping-Pong!

4. By the early 1970s, hacker “Cap’n Crunch” (a.k.a. John Draper) had used a toy whistle to match the 2,600-hertz tone used by AT&T’s long-distance switching system. This gave him access to call routing (and brief access to jail).

5. Before they struck it rich, Apple founders Steve Wozniak and Steve Jobs made and sold “blue boxes,” electronic versions of Draper’s whistle.

6. Using a blue box, Wozniak crank- called the Pope’s residence in Vatican City and pretended to be Henry Kissinger.

7. Hacking went Hollywood in the 1983 movie War Games, about a whiz kid who breaks into a Defense Department computer and, at one point, hijacks a pay phone by hot-wiring it with a soda can pull-ring.

8. That same year, six Milwaukee teens hacked into Los Alamos National Lab, which develops nuclear weapons.

9. In 1988 Robert T. Morris created a worm, or self-replicating program, purported to evaluate Internet security.

10. The worm reproduced too well, however. The multi-million dollar havoc that ensued led to Morris’s felony conviction, one of the first under the Computer Fraud and Abuse Act.
