3. A T-1 multiplexer or a special LAN bridge that connects to the telephone company's channel service unit (CSU) - which encodes data for transmission over a T-carrier circuit.






4. An enhanced version of PPP - which adds the ability to secure the point-to-point connection with encryption.






5. The role of the second EIDE drive on a PATA channel.






6. A finite set of resources controlled by the operating system and critical to the use of all computer components.






7. A set of wires used by data traveling into and out of a processor.






8. Aka optical character recognition.






9. Aka serial ATA.






10. A system by which the computer BIOS and operating system recognizes a device and the operating system automatically installs and configures a device driver.






11. A portable computer small enough to fit in your hand - also referred to as a "palmtop" computer. Because it is so small - a PDA does not have the functionality of a laptop or desktop computer. In other words - a typical PDA allows you to perform only






12. An LCD display using an old technology that has a grid of horizontal and vertical wires with a transistor at the end of each wire. When two transistors (one at the x-axis and one at the y-axis) send voltage along their wires - the pixel at the inters

28. A very old expansion bus standard - seen in the early IBM PC.






29. A drive that is mapped to an empty folder on an NTFS volume and is assigned a drive path rather than drive letters.






30. Aka access control entry.






31. The fine copper lines that are the electronic circuits through which power - data - and control signals travel on a circuit board.






32. The worldwide network that carries traditional voice traffic.
