portals
a Web-based, personalized gateway to information and knowledge that provides relevant information from different IT systems and the Internet using advanced search and indexing techniques
router
a communications processor that routes messages from a LAN to the Internet, across several connected LANs, or across a wide area network such as the Internet.
communications channel
a pathway or medium communicating data from one location to another
industrywide portal
a portal that serves an entire industry ex. trucknet.net
crowdsourcing
a process in which an organization outsources a task to an undefined, generally large group of people in the form of an open call
broadband
based on the Federal Communications Commission (FCC) 2010 definition; the transmission capacity of a communications medium
fiber-optic cable
consists of thousands of very thin filaments of glass fibers that transmit information via light pulses generated by lasers. surrounded by cladding, a coating that prevents the light from leaking out of the fiber
modem (modulator-demodulator)
converts digital signals to analog signals—a process called modulation—and analog signals to digital signals—a process called demodulation
corporate backbone networks
high-speed central networks to which multiple smaller networks (such as LANs and smaller WANs) connect
domain name
home page
file or path
information after forward slash
e-learning
learning supported by the Web. It can take place inside classrooms as a support to conventional teaching, such as when students work on the Web during class. It also can take place in virtual classrooms, in which all coursework is completed
asynchronous
occurs when team members cannot meet at the same time
distance learning
refers to any learning situation in which teachers and students do not meet face-to-face
bandwidth
refers to the transmission capacity of a network; it is stated in bits per second
unified communications
simplifies and integrates all forms of communications (voice, voice mail, fax, chat, e-mail, instant messaging, short message service, presence (location) services, and videoconferencing) on a common hardware and soft ware platform
electronic teleconferencing
the use of electronic communication technology that enables two or more people at different locations to hold a conference
teleconferencing
the use of electronic communication technology that enables two or more people at different locations to hold a conference
workgroup
two or more individuals who act together to perform some task
internet backbone
The primary network connections and telecommunications lines that link the nodes made up of a fiber-optic network that is operated primarily by large telecommunications companies
software-denied networks SDN
an emerging technology that is becoming increasingly important to help organizations manage their data flows across their enterprise networks. decisions controlling how network traffic flows across network devices are managed centrally by software. The software dynamically adjusts data flows to meet business and application needs.
internet2
develops and deploys advanced network applications such as remote medical diagnosis, digital libraries, distance education, online simulation, and virtual laboratories. It is designed to be fast, always on, everywhere, natural, intelligent, easy, and trusted. not a separate physical network from the Internet
synchronous collaboration
all team members meet at the same time
internet
a global WAN that connects approximately 1 million organizational computer networks in more than 200 countries on all continents, including Antarctica. It has become so widespread that it features in the daily routine of some 3 billion people
communication
a major category of network applications related to communication technologies delivered online (e.g., including e-mail, call centers, chat rooms, and voice).
wide area network WAN
a network that covers a large geographical area. WANs typically connect multiple LANs. They are generally provided by common carriers such as telephone companies and the international networks of global communications services providers. WANs have large capacity, and they typically combine multiple channels (e.g., fiber-optic cables, microwave, and satellite). The Internet is an example of a WAN
intranet
a network that uses Internet protocols so that users can take advantage of familiar applications and work habits. support discovery (easy and inexpensive browsing and search), communication, and collaboration inside an organization
virtual group
conduct virtual meetings—that is, they "meet" electronically
extranet
connects parts of the intranets of different organizations
local area network LAN
connects two or more devices in a limited geographical region, usually within the same building, so that every device on the network can communicate with every other device.
digital signals
discrete pulses that are either on or off, representing a series of bits (0s and 1s). convey information in a binary form that can be interpreted by computers
computer network
is a system that connects computers and other devices via communications media so that data and information can be transmitted among them
communications media
is the physical media used to send data (e.g., twisted-pair wire, coaxial cable, fiber optic cable, satellite, etc.).
corporate portal
