A Google application that allows the owner of a web site to host ads. When the ads are clicked on, the web site owner makes revenue.
A Google application that allows users to produce ads to appear in Google searches. Users only pay each time searchers click on their advertisement.
A continuous, linear stream of information. All information has to travel in sequential order (like a phone line or a record)
Analog v. digital
Analog is slower because it requires one, linear path for information transfer. Digital is speedier because the information is broken into pieces (0s and 1s) that can bounce around in packets and then reassemble at the end of the transmisison. It is faster because there are multiple paths for the packets to travel through simultaneously and there is no physical line required.
A type of software, an application lies on top of an operating system and allows the user to manipulate the commands that control the hardware and completeing a specific task. Examples: Word, Excel, Adobe, etc. Google is an Internet application

BOM (Bill of Materials)
describes a product in terms of its assemblies, sub-assemblies, and basic parts. Basically consisting of a list of parts, a BOM is an essential part of the design and manufacture of any product. Often, BOMs contain hierarchical information with the master, or top level, BOM describing a list of components and sub-assemblies. Take a PC, for example: the top level BOM might list the shipping box, manual, packaging, packaging labels and the actual PC. The BOM for the PC itself is referenced in the top level BOM and would contain its own list of sub-assemblies like power supply, motherboard, case, etc.
is a term which refers to a signaling method which includes or handles a relatively wide range of frequencies which may be divided into channels or frequency bins. Broadband is always a relative term, understood according to its context. The wider the bandwidth, the more information can be carried.

Cluetrain Manifesto
The Cluetrain Manifesto is a set of 95 theses organised and put forward as a manifesto, or call to action, for all businesses operating within what is suggested to be a newly-connected marketplace. The ideas put forward within the manifesto aim to examine the impact of the Internet on both markets (consumers) and organisations. In addition, as both consumers and organisations are able to utilise the Internet and Intranets to establish a previously unavailable level of communication both within and between these two groups, the manifesto suggests that the changes that will be required from organisations as they respond to the new marketplace environment.

The manifesto was written in 1999 by Rick Levine, Christopher Locke, Doc Searls, and David Weinberger.

A web crawler (also known as a Web spider or Web robot) is a program or automated script which browses the World Wide Web in a methodical, automated manner. Other less frequently used names for Web crawlers are ants, automatic indexers, bots, and worms (Kobayashi and Takeda, 2000).

This process is called Web crawling or spidering. Many sites, in particular search engines, use spidering as a means of providing up-to-date data. Web crawlers are mainly used to create a copy of all the visited pages for later processing by a search engine, that will index the downloaded pages to provide fast searches. Crawlers can also be used for automating maintenance tasks on a Web site, such as checking links or validating HTML code. Also, crawlers can be used to gather specific types of information from Web pages, such as harvesting e-mail addresses (usually for spam).

A Web crawler is one type of bot, or software agent. In general, it starts with a list of URLs to visit, called the seeds. As the crawler visits these URLs, it identifies all the hyperlinks in the page and adds them to the list of URLs to visit, called the crawl frontier. URLs from the frontier are recursively visited according to a set of policies.
The Defense Advanced Research Projects Agency (DARPA) is the central research and development organization for the Department of Defense (DoD). It manages and directs selected basic and applied research and development projects for DoD, and pursues research and technology where risk and payoff are both very high and where success may provide dramatic advances for traditional military roles and missions.

Google bombing
A certain kind of attempt to influence the ranking of a given page in results returned by the Google search engine, often with humorous or political intentions.[1]
Because of the way that Google's algorithm works, a page will be ranked higher if the sites that link to that page use consistent anchor text. A Google bomb is created if a large number of sites link to the page in this manner.

Metcalfe's law
Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of users of the system (n2). First formulated by Robert Metcalfe in regard to Ethernet, Metcalfe's law explains many of the network effects of communication technologies and networks such as the Internet and World Wide Web.

The law has often been illustrated using the example of fax machines: A single fax machine is useless, but the value of every fax machine increases with the total number of fax machines in the network, because the total number of people with whom each user may send and receive documents increases.

Some argue that Metcalfe's law may exaggerate that benefit. Since a user cannot connect to itself, the reasoning goes, the actual calculation is the number of diagonals and sides in an n-gon (see also the triangular numbers):

However, that value, which simplifies to (n2 − n) / 2, is "Big O" proportional to to the square of the number of users, so this remains the same as Metcalfe's original law.
Moore's law
Moore's Law is the empirical observation made in 1965 that the number of transistors on an integrated circuit for minimum component cost doubles every 24 months.[1][2] It is attributed to Gordon E. Moore (born 1929),[3] a co-founder of Intel. Although it is sometimes quoted as every 18 months, Intel's official Moore's Law page, as well as an interview with Gordon Moore himself, state that it is every two years.

world to accept, edit and publish articles from its readers, in an open source style of news reporting. About 20% of the site's content is written by the 55-person
staff while the majority of articles are written by other freelance contributors who are mostly ordinary citizens.
Open Source
Open source describes the principles and methodologies to promote open access to the production and design process for various goods, products, resources and technical conclusions or advice. The term is most commonly applied to the source code of software that is made available to the general public with either relaxed or non-existent intellectual property restrictions. This allows users to create user-generated software content through either incremental individual effort, or collaboration.
Operating system refers to the system that allows the user to interact with the hardware. The operating system translates the commands. Examples: Windows (90% of all operating systems used), MACOS, LINUX

Reed's law
Reed's law is the assertion of David P. Reed that the utility of large networks, particularly social networks, can scale exponentially with the size of the network.

The reason for this is that the number of possible sub-groups of network participants is , where N is the number of participants. This grows much more rapidly than either

the number of participants, N, or
the number of possible pair connections, (which follows Metcalfe's law)
so that even if the utility of groups available to be joined is very small on a per-group basis, eventually the network effect of potential group membership can dominate the overall economics of the system.
