MIS 180 Chapter 7 – Flashcards

Network Categories, Network Providers, Network Access Technologies, Network Protocols, Network Convergence

Networks offer many advantages for a business including: Sharing resources Providing opportunities Reducing travel Networks create a diverse globally connected world eliminating time and distance Networks make it possible to communicate in ways not previously imaginable Even though networks provide many business advantages, they also create increased challenges in security, social, ethical, and political issues

LAN, WAN, MAN

Connects a group of computers in close proximity, such as in an office building, school, or home

Spans a large geographic area such as a state, province, or country

A large computer network usually spanning a city

NSPs, NAPs, RSPs

Private companies that own and maintain the worldwide backbone that supports the Internet

Traffic exchange points in the routing hierarchy of the Internet that connects NSPs

Offer Internet service by connecting to NSPs, but they also can connect directly to each other

Bandwith Broadband

The maximum amount of data that can pass from one point to another in a unit of time -Bit -Bit rate -Modem

A high-speed Internet connection that is always connected -Digital subscriber line -Internet cable -connection -High speed Internet cable connections -Cable modem -Telecommuting -Broadband over power line

Packet Standard packet format Packet header Packet footer Traceroute Proxy

A standard that specifies the format of data as well as the rules to be followed during transmission

Provides the technical foundation for the public Internet as well as for large numbers of private networks

Converts IP addresses into domains

The efficient coexistence of telephone, video, and data communication within a single network, offering convenience and flexibility not possible with separate infrastructures

The integration of communication channels into a single service

A computer network that relies on the computing power and bandwidth of the participants in the network rather than a centralized server

Uses IP technology to transmit telephone calls

Distributes digital video content using IP across the Internet and private IP networks

Networks offer many advantages for a business including: Sharing resources Providing opportunities Reducing travel

The primary resources for sharing include: Intranet Extranet Virtual private network

Even though networks provide many business advantages, they also create increased challenges in security, social, ethical, and political issues

SSL Certificate Secure hypertext transfer protocol (SHTTP or HTTPS)

An electronic document that confirms the identity of a website or server and verifies that a public key belongs to a trustworthy individual or company

A combination of HTTP and SSL to provide encryption and secure identification of an Internet server

Digital divide - A worldwide gap giving advantage to those with access to technology

Personal Area Networks (PANs) Wireless Local Area (WLANs) Wireless Metropolitan Area Networks (WMANs) Wireless Wide Area Networks (WWANs)

Radio-Frequency Identification (RFID) Global Positioning Systems (GPS) Geographic Information Systems (GIS)

Provide communication over a short distance that is intended for use with devices that are owned and operated by a single user

Wireless PAN technology that transmits signals over short distances between cell phones, computers, and other devices

A local area network that uses radio signals to transmit and receive data over distances of a few hundred feet

A means by which portable devices can connect wirelessly to a local area network, using access points that send and receive data via radio waves

The computer or network device that serves an as interface between devices and the network

Enables devices to connect to a wireless network to communicate with each other

Multiple transmitters and receivers allowing them to send and receive greater amounts of data than traditional networking devices

A metropolitan area network that uses radio signals to transmit and receive data

A communications technology aimed at providing high-speed wireless data over metropolitan area networks

A wide area network that uses radio signals to transmit and receive data

Offer more advanced computing ability and connectivity than basic cell phones

A service that brings wireless broadband to mobile phones

A method of sending audio and video files over the Internet

A space station that orbits the Earth receiving and transmitting signals from Earth-based stations over a wide area

Uses electronic tags and labels to identify objects wirelessly over short distances

An electronic identification device that is made up of a chip and antenna

A transmitter/receiver that reads the contents of RFID tags in the area

Does not have a power source

Contains a transmitter and a power source (typically a battery)

Uses a battery to run the microchip's circuitry, but communicate by drawing power from the RFID reader

Occurs when a company places active or semi-passive RFID tags on expensive products or assets to gather data on the items' location with little or no manual intervention

A device that measures the acceleration (the rate of change of velocity) of an item and is used to track truck speeds or taxi cab speeds

Uses plastic or conductive polymers instead of silicon-based microchips, allowing them to be washed or exposed to water without damaging the chip

A satellite-based navigation system providing extremely accurate position, time, and speed information

Uses GPS tracking to track vehicles

Represents a north/south measurement of position

Represents an east/west measurement of position

A GPS technology adventure game that posts the longitude and latitude location for an item on the Internet for users to find

A round coin-sized object uniquely numbered and hidden in geocache

The time of day of an expected arrival at a certain destination and is typically used for navigation applications

The time remaining before reaching a destination using the present speed and is typically used for navigation applications

Consists of hardware, software, and data that provide location information for display on a multidimensional map

The science and art of making an illustrated map or chart

Occurs when paper maps are laid edge to edge and items that run across maps but do not match are reconfigured to match

Links business assets to a centralized system where they can be tracked and monitored over time

Identifies the geographic location of features and boundaries on Earth, such as natural or constructed features, oceans, and more
