Domain Name System
-Internet's system for converting alphabetic names into numeric IP addresses
-a central mapping of host names to network addresses for domain names
-An application layer protocol used throughout the Internet for translating hostnames into their associated IP addresses
DNS
Dynamic Host Configuration Protocol
-enables a server to automatically assign an IP address to a computer from a define range of numbers
DHCP
Windows Internet Name Service
-Microsoft's implementation fo NetBIOS Name Service (NBNS), a name server and service for NetBIOS computer names
-a central mapping of host names to network addresses to NetBIOS
WINS
-used to map host names to IP addresses (Windows 10/8/7)
Host Files
-organization that provides services accessing and using the Internet
Internet Services
-proprietary suite of networking protocols developed by Apple Inc. for their Mac computers
-allows local area networks to be connected with no prior setup or the need for a centralized router or serve of any sort
AppleTalk
Transmission Control Protocol/Internet Protocol
-a protocol for communication between computers
-used as a standard for transmitting data over networks ad as the basis for standard Internet protocols
-protocol used on the Internet to give each computer a unique address
TCP/IP
Internetwork Packet Exchange/Sequence Packet Exchange
-networking protocols used primarily on networks using the Novell NetWare operating systems
IPX/SPX
NetBIOS Extended User Interface
-program that lets computers communicate within a local area network
-arranges info in a data transmission
NETBEUI
Institute of Electrical & Electronic Engineers (IEEE)
-global association & organization of professionals working toward the development, implementation and maintenance of technology-centered products & services
IEEE
International Organization for Standardization
-international standard-setting body composed of representatives from various national standards organizations
ISO
Network Interface Card
-contains electronic circuitry required to communicate using a wired connection or a wireless connection
NIC
Media Access Control
-responsible for the transmission of data packets to and from the network-interface card, and to and from another remotely shared channel
MAC
-help reduce interference to network signals
Shielding
-occur in microcircuits within computers & audio equipment as well as within network circuits
Crosstalk
-refers to any reduction in the strength of a signal
-occurs with any type of signal, whether digital or analog
-a natural consequence of signal transmission over long distances
Attenuation
-high-speed Internet access that is always on and faster than the traditional dial-up access
-a method of transmitting data in the form of several analog signals at the same time
Broadband
Integrated Services Digital Network
-a set of communication standards for simultaneous digital transmission of voice, video, data, & other network services over the traditional circuits of the public switched telephone network
ISDN
Switched Multimegabit Data Service
-public, packet-switched service aimed at enterprises that need to exchange large amounts of data with other enterprises over the wide-area network on a nonconstant basis
SMDS
Asynchronous Transfer Mode
-a switching technique used by telecommunication networks that uses asynchronous time-division multiplexing to encode data into small, fixed-sized cells
-A high-speed, packet-switching technique that uses short fixed-length packets called cells, and can transmit voice, video, and data over a variable-speed LAN and WAN connections, is best described by which one of the following?
ATM
-RJ11 is wired for two lines
-RJ45 jack is rarely used but commonly refers to any 8P8C modular connector for application in computer networking (ethernet)
RJ45 & RJ11
Straight Tip Connector
-a fiber-optic cable connector that uses a bayonet (spear like) plug and socket
ST
