Answer 1

bandwidth
1. The difference between the highest and lowest frequencies that an analog communications system can pass as measured in Hertz (Hz) or cycles per second. For example, a telephone accommodates a bandwidth of 3,000 Hz: the difference between the lowest (300 Hz) and highest (3,300 Hz) frequencies it can carry. 2. The data transfer capacity, or speed of transmission, of a digital communications system as measured in bits per second (bps).

BTW or btw
Acronym for by the way. An expression often used to preface remarks in e-mail and Internet newsgroup articles

cyberpunk
1. A genre of near-future science fiction in which conflict and action take place in virtual-reality environments maintained on global computer networks in a worldwide culture of dystopian alienation. The prototypical cyberpunk novel is William Gibson's Neuromancer (1982). 2. A category of popular culture that resembles the ethos of cyberpunk fiction. 3. A person or fictional character who resembles the heroes of cyberpunk fiction.

firewall
A security system intended to protect an organization's network against external threats, such as hackers, coming from another network, such as the Internet. Usually a combination of hardware and software, a firewall prevents computers in the organization's network from communicating directly with computers external to the network and vice versa. Instead, all communication is routed through a proxy server outside of the organization's network, and the proxy server decides whether it is safe to let a particular message or file pass through to the organization's network.

flame1
An abusive or personally insulting e-mail message or newsgroup posting.

HTTP
Acronym for Hypertext Transfer Protocol. the protocol used to carry requests from a browser to a Web server and to transport pages from Web servers back to the requesting browser. Although HTTP is almost universally used on the Web, it is not an especially secure protocol.

internet
Short for internetwork. A set of computer networks that may be dissimilar and are joined together by means of gateways that handle data transfer and conversion of messages from the sending networks' protocols to those of the receiving network.

Internet
The worldwide collection of networks and gateways that use the TCP/IP suite of protocols to communicate with one another. At the heart of the Internet is a backbone of high-speed data communication lines between major nodes or host computers, consisting of thousands of commercial, government, educational, and other computer systems, that route data and messages. One or more Internet nodes can go off line without endangering the Internet as a whole or causing communications on the Internet to stop, because no single computer or network controls it. The genesis of the Internet was a decentralized network called ARPANET created by the Department of Defense in 1969 to facilitate communications in the event of a nuclear attack. Eventually other networks, including BITNET, Usenet, UUCP, and NSFnet, were connected to ARPANET. Currently, the Internet offers a range of services to users, such as FTP, e-mail, the World Wide Web, Usenet news, Gopher, IRC, telnet, and others. Also called the Net.

intranet
A private network based on Internet protocols such as TCP/IP but designed for information management within a company or organization. Its uses include such services as document distribution, software distribution, access to databases, and training. An intranet is so called because it looks like a World Wide Web site and is based on the same technologies, yet is strictly internal to the organization and is not connected to the Internet proper. Some internets also offer access to the Internet, but such connections are directed through a firewall that protects the internal network from the external Web.

ISP
Acronym for Internet service provider. A business that supplies Internet connectivity services to individuals, businesses, and other organizations. Some ISPs are large national or multinational corporations that offer access in many locations, while others are limited to a single city or region. Also called access provider, service provider.

Mosaic
The first popular graphical World Wide Web browser. Released on the Internet in early 1993 by the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign, Mosaic is available as freeware and shareware for Windows, Macintosh, and X Window systems. Mosaic is distinguished from other early Web browsers by its ease of use and its addition of inline images to Web documents. Also called NCSA Mosaic.

netiquette
Short for network etiquette. Principles of courtesy observed in sending electronic messages, such as e-mail and Usenet postings. The consequences of violating netiquette include being flamed and having one's name placed in the bozo filter of one's intended audience. Disapproved behavior includes gratuitous personal insults; posting of large amounts of irrelevant material; giving away the plot of a movie, television show, or novel without warning; posting offensive material without encrypting it; and excessive cross-posting of a message to multiple groups without regard to whether the group members are likely to find it interesting.

netizen
A person who participates in online communication through the Internet and other networks, especially conference and chat services, such as Internet news or Fidonet.

node
1. A junction of some type. 2. In networking, a device, such as a client computer, a server, or a shared printer, that is connected to the network and is capable of communicating with other network devices. 3. In tree structures, a location on the tree that can have links to one or more nodes below it. Some authors make a distinction between node and element, with an element being a given data type and a node comprising one or more elements as well as any supporting data structures.

search engine
1. A program that searches for keywords in documents or in a database. 2. On the Internet, a program that searches for keywords in files and documents found on the World Wide Web, newsgroups, Gopher menus, and FTP archives. Some search engines are used for a single Internet site, such as a dedicated search engine for a Web site. Others search across many sites, using such agents as spiders to gather lists of available files and documents and store these lists in databases that users can search by keyword. Examples of the latter type of search engine are Lycos and Excite. Most search engines reside on a server.

Answer 3

1:
The amount of data that can be transmitted in a fixed amount of time
2:
Abbreviation for "By the Way" used in e-mail, newsgroup, and chat communication
3:
literary term used to describe a genre based on science fiction, but with emphasis on advanced technology. Cyberpunk was inspired by William Gibson's 1982 novel "Neuromancer".

4:
.) A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.


5:
A searing e-mail or newsgroup message in which the writer attacks another participant in overly harsh, and often personal, terms. Flames are an unfortunate, but inevitable, element of unmoderated conferences.
6:

Short for HyperText Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.
The other main standard that controls how the World Wide Web works is HTML, which covers how Web pages are formatted and displayed.

7:

A global network connecting millions of computers. More than 100 countries are linked into exchanges of data, news and opinions.
8:
no doffrence with Internet

9:


A network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization. An intranet's Web sites look and act just like any other Web sites, but the firewall surrounding an intranet fends off unauthorized access.

10:
Short for Internet Service Provider, a company that provides access to the Internet. For a monthly fee, the service provider gives you a software package, username, password and access phone number. Equipped with a modem, you can then log on to the Internet and browse the World Wide Web and USENET, and send and receive e-mail.

11:
An application that simplifies accessing documents on the World Wide Web. Originally produced by the National Center for Supercomputing Applications (NCSA), Mosaic has always been distributed as freeware. In 1994, however, the NCSA turned over commercial development of the program to a company called Spyglass. There are now several varieties of Mosaic, some free and some for sale.

12:

Contraction of Internet etiquette, the etiquette guidelines for posting messages to online services, and particularly Internet newsgroups. Netiquette covers not only rules to maintain civility in discussions (i.e., avoiding flames), but also special guidelines unique to the electronic nature of forum messages. For example, netiquette advises users to use simple formats because complex formatting may not appear correctly for all readers. In most cases, netiquette is enforced by fellow users who will vociferously object if you break a rule of netiquette.

13:
A Netizen (a portmanteau of Internet and citizen) [also known as a cybercitizen] is a person actively involved in online communities. Netizens use the Internet to engage in activities of the extended social groups of the internetworks (i.e., giving and receiving viewpoints, furnishing information, fostering the Internet as a intellectual and a social resource, and making choices for the self-assembled communities


14:

In networks, a processing location. A node can be a computer or some other device, such as a printer.

15:

A program that searches documents for specified keywords and returns a list of the documents where the keywords were found. Although search engine is really a general class of programs, the term is often used to specifically describe systems like Alta Vista and Excite that enable users to search for documents on the World Wide Web and USENET newsgroups.

Answer 4

Bandwidth = A measure of the capacity of a communications channel. The higher a channel's bandwidth, the more information it can carry. OR The amount of information or data that can be sent over a network connection in a given period of time. Bandwidth is usually stated in bits per second (bps), kilobits per second (kbps), or megabits per second (mps).

BTW = Abbreviation for "By the Way" used in e-mail, newsgroup, and chat communication.

Generally set in the near future, often with psychadellic effects, often dangerous morality. An example is the film The Matrix.

Firewall = a hardware or software solution to enforce security policies. In the physical security analogy, a firewall is equivalent to a door lock on a perimeter door or on a door to a room inside of the building - it permits only authorized users such as those with a key or access card to enter. A firewall has built-in filters that can disallow unauthorized or potentially dangerous material from entering the system. It also logs attempted intrusions.

HTTP = Abbreviation for Hyper Text Tranfer Protocol

Internet / internet = An electronic network of computers that includes nearly every university, government, and research facility in the world. Also included are many commercial sites. It started with four interconnected computers in 1969 and was known as ARPAnet.
Note: The only difference is of "I", "i"

ISP = Abbreviation for Internet Service Provider

Mosaic = Mosaic is a web browser (client) for the World Wide Web written at the National Center for Supercomputing Applications (NCSA). Its development began in 1992 and officially ceased on January 7, 1997.

Netiquette = Unofficial rules defining proper behaviour on Internet.

Netizen = Derived from the term citizen, referring to a citizen of the Internet, or someone who uses networked resources. The term cannotes civic responsibility and participation.

Node = A single machine on a network.

Search Engine = Software that enables users to search the Internet using keywords. Examples of well known services of this type are AltaVista and Google!. For more information consult our Internet Reference section.

Answer 5

Here is a fast way to get definitions:

Download the Firefox browser (it's better than Internet Explorer anyway).

Then just go to the address bar (where you type in the names of web sites) and type:
dict [word]

(that is, the word "dict" followed by the word that you want defined.)

Answer 6

1. Bandwidth - The space on a communication line for carrying data, a higher amount of bandwidth means that a cable can carry information faster.

2. BTW - An abbreviation for the phrase "By The Way"

3. Cyberpunk - A term originally coined by the author William Gibson referring to a sort of future class of criminal/mercenary/vigilante who uses electronics, hacking and/or cybernetic implants.

4. Firewall - A piece of software that monitors and restricts information going through a network connection. Typically used to protect computers/networks from attacks by hackers.

5. Flame - A term that refers to making abusive, insulting and overly aggressive posts on an online forum.

6. HTTP - HyperText Transfer Protocol, a communications protocol most frequently used to request and send web pages over the Internet.

7. Internet - The global, public electronic network that connects computers around the world, all coordinated using the IP protocol (IP = Internet Protocol, a protocol used to identify the position of particular computers on the Internet). The capital "I" should always be used with Internet if you use the word as a noun, since Internet is a proper noun, like France or Sarah.

Examples of when you should use the capital I:

I can't connect to the Internet
We've been on the Internet since July
They've been talking to each other over the Internet

8. internet - An adjective meaning "related to/using the Internet". Also used to refer to any network of computer's

Examples of when to NOT use a capital I:

Is there something wrong with our internet connection?
TCP/IP is an internet communication protocol.
An Intranet is a small internet.

9. Intranet - An electronic network that connects the computers within a particular company or organisation. Basically a small, private version of the global Internet.

10. ISP - Internet Service Provider, a company that rents out bandwidth for members of the public to connect to the Internet.

11. Mosaic - Has (according to Wikipedia) many computer related meanings:

http://en.wikipedia.org/wiki/Mosaic_%28disambiguation%29

In brief:
- A way of pixelating an image to censor it
- The name of a particular piece of software used to analyze data from radio telescopes
- The name of a particular piece of software used in the UK for marketting purposes
- The name of an old piece of software for browsing the WWW (probably the meaning you're looking for)

12 - Netiquette - The rules of etiquette one should follow when taking part in online communities (i.e. Forums, Chat rooms). For example flaming and trolling (deliberately making posts to upset people/cause arguments) are examples of bad Netiquette.

13 - Netizen - Literally InterNET citIZEN, someone who uses the Internet.

14 - Node - A single point within a connected graph. This is a hard one to explain properly, a "connected graph" is any graph where you have a number of points, which are connected together using lines. It might represent a computer network where each point is a computer (or other piece of network hardware, like a Router or Switch) and each line representing a cable running from one thing to another. It may also represent a country's train system, with each point being a station and each line representing a piece of track going from one station to another. Each line on such a graph is called an "edge" and each point a "node". Therefore the computer you're using to read this is one Node on the Internet.

15 - Search Engine - A piece of software used for searching the Internet to find information on a particular subject. Typically search engines work by using Spiders (sort of like a piece of software that explores the Internet) to regularly search the Internet in order to build a directory of what words are contained on what pages. When the user enters a search word the software searches its directory to locate all web pages that contain that word.

Answer 7

Bandwidth = A measure of total amount of data transferred over a period of time, often used to measure how busy a website is. A webhost will usually base its charges on the bandwidth a website uses, ie how much data per month is requested from it.

BTW = (By The Way) Internet slang.

Cyberpunk = A subgenre of Science Fiction; this deals with the effect of the internet/virtual reality/cloning/etc. (i.e., plausible science fiction) within a Dark Science Fiction setting. Generally set in the near future, often with psychadellic effects, often dangerous morality. An example is the film The Matrix.

Firewall = Originally a dedicated computer between you and the internet, preventing hackers, spammers and similar undesirables from taking over your PC. Now often just a program running on your PC, performing the same task. Absolutely essential if you have an always-on internet connection such as ADSL or cable.

Flame = Internet slang for an email or newsgroup post insulting or telling someone off. They range from elegant rapier wit to obscene profanity.

HTTP = (HyperText Transfer Protocol) The protocol or "language" computers use to send web pages over the internet. Almost every WWW address starts "http://", though many browsers understand if you omit it.

Internet = A vast worldwide network of computers, accessible to anyone with a computer, a modem, and a phone line. Provides access to e-mail and the World Wide Web. The Internet grew out of the need of academics to swap information with colleagues all over the world, and of the US military's need for a computer and communications network that couldn't easily be knocked out. As a result it is very difficult to censor, since anything placed on the World Wide Web from anywhere is instantly available everywhere in the world.

Internet = A private miniature internet which allows no or only limited access to the internet proper, for example to allow easy sharing of confidential files within a company or corporation.

ISP = (Internet Service Provider) A company which provides a connection to the internet, or internet services.

Mosaic = Definitions of mosaic on the Web:

* art consisting of a design made of small pieces of colored stone or glass
* viral disease in solanaceous plants (tomatoes, potatoes, tobacco) resulting in mottling and often shriveling of the leaves
* a freeware browser
* a pattern resembling a mosaic
* transducer formed by the light-sensitive surface on a television camera tube
* of or relating to Moses or the laws and writings attributed to him; "Mosaic Law"
* assembly of aerial photographs forming a composite picture
* decorated with small pieces of colored glass or stone fitted together; "a mosaic floor"; "a tessellated pavement"

Netiquette = The informal rules of Internet etiquette.

Netizen = "Netiquette" is network etiquette, the do's and don'ts of online communication. Netiquette covers both common courtesy online and the informal "rules of the road" of cyberspace

Node = Any device connected to network. PCs, servers, and printers are all nodes on the network.

Search Engine = A website directory which indexes as many websites as it can and allows you to search its database for sites on particular subjects. Because of the immense size and rate of growth of the world wide web, no-one has a complete directory of all sites which exist. The most popular is Google.

As for internet vs Internet -- they are the same thing, but you should only write it with a capital "I".

Answer 10

Bandwidth
========
Bandwidth is the amount of data that can be transferred over the network in a fixed amount of time. On the Net, it is usually expressed in bits per second (bps) or in higher units like Mbps (millions of bits per second). 28.8 modem can deliver 28,800 bps, a T1 line is about 1.5 Mbps.

BTW
====
Abbreviation for "By the Way" used in e-mail, newsgroup, and chat communication.

Cyberpunk
========
Cyberpunk (a portmanteau of cybernetics and punk) is a sub-genre of science fiction which focuses on computers or information technology, usually coupled with some degree of breakdown in social order. The plot of cyberpunk literature often revolves around the conflict between hackers, artificial intelligences, and megacorps, tending to be set within a near-future dystopian Earth, rather than the 'outer space' locales prevalent at the time of cyberpunk's inception.
A subgenre of Science Fiction; this deals with the effect of the internet/virtual reality/cloning/etc. (ie, plausible science fiction) within a Dark Science Fiction setting. Generally set in the near future, often with psychadellic effects, often dangerous morality. An example is the film The Matrix. A term coined by science fiction writers William Gibson and Bruce Sterlingreffering for a sub-group existing in an overindustrialised society. It is a cultural label used for many different kinds of human, machine, and punk attitudes, including clothing and lifestyle.

Firewall
======
A firewall is a hardware or software solution to enforce security policies. In the physical security analogy, a firewall is equivalent to a door lock on a perimeter door or on a door to a room inside of the building - it permits only authorized users such as those with a key or access card to enter. A firewall has built-in filters that can disallow unauthorized or potentially dangerous material from entering the system. It also logs attempted intrusions.

Flame
=====
-- criticize harshly, in e-mail, chat rooms or discussion boards. Originally, flame meant to carry forth in a passionate manner in the spirit of honorable debate.

internet
======
internet is short for internetwork which is a collection of interconnected networks.

Intranet
=====
Inter-connected network within one organization that uses Web technologies for the sharing of information internally, not world wide. Such information might include organization policies and procedures, announcements, or information about new products.
