| bus | a pathway for signals to flow bettween funcitional elements of the computer. |
| data bus | a pathway linking the cpu to memory and i/o devices |
| address bus | a pathway that carries data generated by the cpu to the varius memory and i/o elements. |
| pc bus | the bus architecture used in the first ibm bus originally an 8 bit but bus expanded to a 16 bit bus |
| ISA | industry standard architecture. Te 8 and 16 bit original connectors used in dos |
| EISA | extended industy stndard architecture 16 bit isa was extended to a 32 bit and they are cakked EISA |
| PCI | peripheral system interconnects high performance 32/64 bit bus |
| Plug and play | this is a standard that was suppost to make adding pleriplerals to your system as easy as plugging them in and using them |
| Bandwidth | a measure in some amount of bit per sec of them amout of data |
| Bus master | any class of microprossesor unit with the ability to take control of the system busses of a computer |
| Bus speed | a measurement usually ni MHz of how many times data can be transfered where the bus per second |
| Expansion slots | refers to any type of slot in a computer that you can plug an expansion sloy card into |
| legacy | that whitch is handed down form a processor. In the compouter field, it referrs to the previous major pentium. |
| Fire wall | a method for keeping a network secure from intruders |
| adapter | A device that allows one system to connect to and work with another |
| interrupt | A signal that gets the attention of the CPU and is usually generated when I/O is required |
| jumper | The simplest form of an on/off switch. It is just a tiny, plastic-covered metal block, which is pushed onto two pins to close that circuit. |
| DMA | Document Management Alliance) A specification that provides a common interface for accessing and searching document databases |
| i/o address | On PCs, a three-digit hexadecimal number (2AB, 2A0, etc.) used to identify and signal a peripheral device (serial port, parallel port, sound card, etc.). |
| AGP | (Accelerated Graphics Port) A high-speed graphics port from Intel that provides a direct connection between the display adapter and memory. |
| framing rate | A Web browser feature that enables a Web page to be displayed in a separate scrollable window on screen. Older browsers do not support the frames feature, and many Web sites have a frames and non-frames version of the site to accomodate them. |
| data rate | The data transfer speed within the computer or between a peripheral and computer. |
| baud rate | A redundant reference to baud. Baud is a rate. |
| handshacking | comunicating with other computers |
| io port | The identifying address of a peripheral device. |
| centronics | A standard 36-pin parallel interface for connecting printers and other devices to a computer. It defines the plug, socket and signals used and transfers data asynchronously up to 200 Kbytes/sec. The plug has 18 contacts each on the top and bottom. The socket contains one opening with matching contacts. |
| usb standard | Universal Serial Bus) A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick, scanner, printer and telephony devices. It also supports MPEG-1 and MPEG-2 digital video. USB has a maximum bandwidth of 12 Mbits/sec (equivalent to 1.5 Mbytes/sec), and up to 127 devices can be attached. Fast devices can use the full bandwidth, while lower-speed ones can transfer data using a 1.5 Mbits/sec subchannel. |
| hot swap | To pull out a component from a system and plug in a new one while the power is still on and the unit is still operating. Redundant systems can be designed to swap drives, circuit boards, power supplies, virtually anything that is duplexed within the computer. See warm swap, hot fix and hot spare. |
| fire wall | A method for keeping a network secure from intruders. It can be a single router that filters out unwanted packets or may comprise a combination of routers and servers each performing some type of firewall processing. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network. Firewalls are also used to keep internal network segments secure; for example, the accounting network might be vulnerable to snooping from within the enterprise. |
| isochronous | Time dependent. Realtime voice, video and telemetry are examples of isochronous data. |
