Standard Connector
-a fiber-optic cable connector that uses a push-pull latching mechanism similar to common audio and video cables
SC
Lucent Connector
-a miniaturized version of the fiber-optic SC connector
LC
-a fiber-optic cable connector that is very popular for small form factor devices due to its small size
MT-RJ
Universal Serial Bus
-common interface that enables communication between devices and a host controller such as a personal computer (PC)
-it connects peripheral devices such as digital cameras, mice, keyboards, printers, scanners, media devices, external hard drives and flash drives
USB
-a device or program that enables a computer to transmit data over
-Ex: telephone or cable lines
Modems
Channel Service Unit/Data Service Unit
-a digital-interface device used to connect data terminal equipment (DTE), such as a router, to a digital circuit, such as a Digital Signal 1 (DS1)
DSL/CSU
-a type of computer network device that provides interconnection with other bridge networks that use the same protocol
-In telecommunication networks, a ______ is a product that connects a local area network (LAN) to another local area network that uses the same protocol.
-The primary function of a bridge is to keep traffic separated on both sides of the bridge, breaking up collision domains
Bridge
-a computer networking device that connects devices together on a computer network by using packet switching to receive, process, & forward data to the destination device
Switch
Redundant Array of Inexpensive Disks
-storage that uses multiple disks in order to provide fault tolerance, to improve overall performance, and to increase storage capacity in a system
RAID
a blade server needs a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management
Blades
Symmetric Multiprocessing
-involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices
-are controlled by a single operating system
SMP
-a set of parallel interface standards developed by the American National Standards Institute (ANSI) for attaching printers, disk drives, scanners and other peripherals to computers
SCSI
-a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections
Wi-Fi
Worldwide Interoperability for Microwave Access
-a wireless industry coalition dedicated to the advancement of IEEE 802.16 standards for broadband wireless access (BWA) networks
WiMax
Global System for Mobile Communications
-a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation digital cellular networks
GSM
signal that is one in which a base carrier's alternating current frequency is modified in some way
(such as by amplifying the strength of the signal or varying the frequency, in order to add information to the signal)
Analog
-used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc
Cable
Digital Subscriber Line
-a communications medium used to transfer digital signals over standard telephone lines
DSL
Open Systems Interconnection
-reference model for how applications can communicate over a network
-a reference model is a conceptual framework for understanding relationships
OSI
Layer 7--Application layer
Layer 6--Presentation layer
Layer 5--Session layer
Layer 4--Transport layer
Layer 3--Network layer
Layer 2--Data Link layer
Layer 1--Physical layer
OSI layers
an arrangement in a local area network (LAN) in which each node (workstation or other device) is connected to a main cable or link called the bus
Bus
a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node
Ring
