HTTP

protocol to interconnect files on the internet

coaxial wire

a single strand of insulated copper wire. It is much less susceptible to electrical interference, and it can carry much more data than twisted-pair. It is commonly used to carry high-speed data traffic as well as television signals

world wide web

a system of universally accepted standards for storing, retrieving, formatting, and displaying information via a client/server architecture

virtual collaboration

the use of digital technologies that enable organizations or individuals who are geographically dispersed to collaboratively plan, design, develop, manage, and research products, services, and innovative applications

hypertext

-is the underlying concept defining the structure of the World Wide Web. -text displayed on a computer display or other electronic device with references to other text that the reader can immediately access, or where text can be revealed progressively at additional levels of details

ethernet

A common LAN protocol. Many organizations use 100-gigabit, where the network provides data transmission speeds of 100 gigabits (100 billion bits) per second

telecommuting

A process in which knowledge workers are being called the distributed workforce, or "digital nomads." This group of highly prized workers is now able to work anywhere and anytime.

virtual universities

Online universities in which students take classes via the Internet at home or an off-site location

telepresence

The latest form of videoconferencing which enables participants to seamlessly share data, voice, pictures, graphics, and animation by electronic means

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

offers a personalized, single point of access through a Web browser to critical business information located inside and outside an organization. These portals are also known as enterprise portals, information portals, and enterprise information portals

affinity portal

offers a single point of entry to an entire community of affiliated interests, such as a hobby group or a political party

enterprise network

organizational interconnected networks consisting of multiple LANs and may also include multiple WAN's

videoconference

participants in one location can view participants, documents, and presentations at other locations

unified communication

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

commercial (public) portal

the most popular type of portal on the Internet and is intended for broad and diverse audiences (e.g., a stock ticker)

twisted-pair wire

the most prevalent form of communications wiring used for almost all business telephone wiring and As the name suggests, it consists of strands of copper wire twisted in pairs. It is relatively inexpensive to purchase, widely available, and easy to work with

workflow

the movement of information as it progresses through the sequence of steps that make up an organization's work procedures. Workflow management makes it possible to pass documents, information, and tasks from one participant to another in a way that is governed by the organization's rules or procedures

transmission control protocol/internet protocol

the protocol of the Internet. TCP/IP uses a suite of protocols, the main ones being the Transmission Control Protocol (TCP) and the Internet Protocol (IP)
