Management Information Systems Chapter 7

Any Computer on the network that requests and sues the services provided by the server
A computer that is specifically optimized to provide software and other resources to other computers on the network
Network Interface Device
Each computer on the network contains a network interface device to link the computer to the network; serves as a unique identifier
Connect Medium
The connection medium used to link network components (telephone wires, cable, radio signal)
Network Operating System
Routes and manages communications on the network and coordinates network resources. May reside on every computer or on a dedicated server
Device used to connect network components sending packets of data to all other connected devices. Least intelligent and expensive
Used to filter and forward data to a specified destination on the network. More efficient than hub
A special communications processor used to route packets of data through different networks, ensuring that the data sent gets to the correct address. Smartest and most complicated.
Client/server computing
A form of distributed computing that partitions software processes between client and server computers
Packet switching
Allows millions of users to send chunks of data across the Internet. Messages are broken down into small fixed bundles called packets
A set of rules and procedures governing transmission of information between two points in a network
Local Area Network (LAN)
Designed to connect personal computers and other digital devices within a half-mile. (Star, Bus, and ring)
Wide-Area Network
Span large geographical distance
used to connect two or more LANs (the Internet)
Metropolitan-Area Network
A network that spans an urban place, like a city and its suburbs
uses fiber optics and wireless infrastructure
Twisted Pair
Physical Transmission
Inexpensive, easy to install and reconfigure.
Drawbacks include highly susceptible to eavesdropping and not suitable for high speeds
Physical Transmission
higher bandwidth, lower susceptibility of eavesdropping, more expensive than twisted pair, more difficult to install and configure
Physical Transmission
very high bandwidth, immune to eavesdropping , more expensive than coaxial
Wireless Transmission
uses a high frequency radio signal that is sent through the air using either terrestrial or satellite systems to transmit data over long distances
Wireless Transmission
uses radio waves to communicate with radio antennas
Wireless Transmission
may use LAN or mobile access points
IP Address
IPv4 was written as 4 numbers separated by periods
any device on a network must have its own unique address
IPv6 written to provide more possibilities
Voice over IP
uses the Internet Protocol to deliver voice information on digital form using packet switching
Virtual Private Network
A secure connection between two points acess the Internet to transmit corporate data. Provides low0cost alternative to a private network
HTTP Hypertext Transfer Protocol
The set of standards used by web servers to process user requests for web pages
Radio Frequency Identifican
Provide powerful technology for tracking the movement of goods throughout the supply chain
Wireless Sensor Network
Networks of interconnected wireless devices that are embedded into the physical environment to provide measurements of many points over large spaces
Web Server
software for locating and managing stored Web pages
