GLOSSARY 10BaseT Ethernet LAN designed to run on UTP ca- bling. 10BaseT runs at 10 megabits per second. The maximum length for the cabling between the NIC and the hub (or switch, repeater, etc.) is 100 meters. It uses baseband signaling. No industry standard spelling ex- ists, so sometimes written 10BASE-T or 10Base-T. 100BaseT Generic term for an Ethernet cabling sys- tem designed to run at 100 megabits per second on UTP cabling. It uses baseband signaling. No industry stan- dard spelling exists, so sometimes written 100BASE-T or 100Base-T. 1000BaseT Gigabit Ethernet on UTP. 2.1 Speaker setup consisting of two stereo speakers combined with a subwoofer. 3.5-inch floppy drive All modern floppy disk drives are of this size; the format was introduced in 1986 and is one of the longest surviving pieces of computer hardware. 34-pin ribbon cable Type of cable used by floppy disk drives. 3-D graphics Video technology that attempts to cre- ate images with the same depth and texture as objects seen in the real world. 40-pin ribbon cable Type of cable used to attach EIDE devices (such as hard drives) or ATAPI devices (such as optical drives) to a system. 5.1 speaker system Four satellite speakers plus a cen- ter speaker and a subwoofer. 8.3 naming system File-naming convention that spec- ified a maximum of eight characters for a filename, fol- lowed by a 3-character file extension. Has been replaced by LFN (long filename) support. 80-wire ribbon cable Type of cable used to attach fast EIDE devices (such as ATA/100 hard drives) or ATAPI devices (such as optical drives) to a system. 802.11a Wireless networking standard that operates in the 5-GHz band with a theoretical maximum throughput of 54 Mbps. 802.11b Wireless networking standard that operates in the 2.4-GHz band with a theoretical maximum throughput of 11 Mbps. 802.11g Wireless networking standard that operates in the 2.4-GHz band with a theoretical maximum throughput of 54 Mbps and is backward compatible with 802.11b. 802.11n Wireless networking standard that can operate in both the 2.4-GHz and 5-GHz bands and uses MIMO to achieve a theoretical maximum throughput of 100+ Mbps. A/V sync Process of synchronizing audio and video. AC (alternating current) Type of electricity in which the flow of electrons alternates direction, back and forth, in a circuit. AC’97 Sound card standard for lower-end audio de- vices; created when most folks listened to stereo sound at best. access control Security concept using physical secu- rity, authentication, users and groups, and security policies. ACPI (advanced configuration and power interface) Power management specification that far surpasses its predecessor, APM, by providing support for hot- swappable devices and better control of power modes. activation Process of confirming that an installed copy of a Microsoft product (most commonly Windows or a Microsoft Office application) is legitimate. Usually done at the end of software installation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
