WEB 2.0

webmail

Web-based or webmail is email that is accessed through the web and stays on the web. The main benefit is that the user can access their mail at any location with a computer that has a internet connection. The first webmail service was Hotmail and is still one of the most popular.

Discussion boards

replacing newsgroups, a discussion board is an online bulletin board where you can read and leave messages for the public or members of that site. The first discussion boards were available on bulletin board systems.

IM

Instant Messaging - Anyone on a given e-mail system can send a message and have it pop up instantly on the screen of anyone else logged onto that system. examples of instant messaging systems are AOL, MSN and Yahoo
PROS: allows a faster way of communication than email, and can reduce long distance bills CONS: lack of privacy, many IM products don't communicate with another, and can destroy concentration when working.

Blog

A blog (short for weblog) is a personal online journal that is frequently updated and intended for general public consumption. Blogs are defined by their format: a series of entries posted to a single page in reverse-chronological order.Blogs generally represent the personality of the author or reflect the purpose of the Web site that hosts the blog. Topics sometimes include brief philosophical musings, commentary on Internet and other social issues, and links to other sites the author favors, especially those that support a point being made on a post.
Before blogging became popular, digital communities took many forms, including Usenet, commercial online services such as GEnie, BiX and the early CompuServe, e-mail lists and Bulletin Board Systems (BBS).

VoIP

Voice Over Internet Protocol is a type of internet telephony in which the net is used to make phone calls, either one on one or for audio-conferencing. You can make long distance phone calls that are surprisingly cheap or even free.
Skype is one of the most popular program that use VoIP, and is currently expanding into the wireless cellular division. The expansion of the WiMax network will dramatically change the current market of cellular technology.

Webcast

Webcasting is where customized text, video, and audio samples are sent to you automatically on a regular basis. You choose the categories or channels of websites that will automatically send you updated information. It saves time because you don't have to search for the information.

Quotes on Age and Aging

"Like spring, but it is too young. I like summer, but it is too proud. So I like best of all autumn, because its tone is mellower, its colors are richer, and it is tinged with a little sorrow. Its golden richness speaks not of the innocence of spring, nor the power of summer, but of the mellowness and kindly wisdom of approaching age. It knows the limitations of life and its content."

Lin Yu-tang

"I always looked to about thirty as the barrier of any real or fierce delight in the passions, and determined to work them out in the younger ore and better veins of the mine --and I flatter myself (perhaps) that I have pretty well done so --and now the dross is coming."

Byron, Lord

"When we are out of sympathy with the young, then I think our work in this world is over."

Macdonald, George

"Middle age is when a guy keeps turning off lights for economical rather than romantic reasons."

Cass, Eli

"For age is opportunity no less than youth itself, though in another dress, and as the evening twilight fades away, the sky is filled with stars, invisible by day."

Longfellow, Henry Wadsworth

INTERNET ADDRESSING

URL

URL means, "Uniform Resource Locator", by definition is a pointer to a websites resource and is needed to differentiate websites.

It is a string of characters that locates a specific piece of information anywhere on the web. (for example: http://www.wikipedia.org is the URL to Wikipedia) This shows an HTTP Protocol.

An URL can also be broken down into parts.
*You could add a path component that specifically references the host computer.
*You can add a portthat shows where the TCP connection is made on the remote host machine.
*You could add a fragment(AKA: reference) that could specify a specific section you are looking for.

domains

A domain is a location on the internet. It's a particular web server and is the middle part of the address. The domain name tells the location and the type of address. Components of domain names are separated by periods or dots. The three letter extension at the end describes type of domain such Google (www.Google.com), or Government (www.gov.ca) etc. the "Google" and "gov" are the domains.

top level

Top level domain is the end of a domain. So this is the end of an address. For example .com .org .net. Some top level domain names also include a two letter code extension for the country for ex: .us .mx .uk .ca

email

Email addresses are a type of electronic mailboxes used to send and receive messages, all addresses follow the same format which is : username@domain (i.e. jdoe@gmail.com). The major difference between addresses and URL's are the absence of the "@" symbol.

NETWORKING

Networking is a Department under the School of Computer Science. Courses focus on the interconnection of computing systems to share resources, and ultimately should provide an ever-increasing level of complexity in subject material, much as advancing classes in a traditional university do.
Networking is the practice of enabling and harnessing the transmission of data from one computer system to another. A crude analogy of a data network is pictured at right: two tin cans connected by a simple string. Note that what this basic analogy suggests holds true for actual implementations of data networks:

• The network exists merely as a medium for communications of some kind, across it
• A protocol of some form is needed to initiate and carry on conversations (this is not intrinsic to the network itself)
• The same protocol (a spoken language) can also be used with different media for the same purpose; different networks have different advantages and uses

A network may require one engineer to design it, another engineer to build it, and another engineer entirely to administer it. The skills needed for each stage in the process are related but not necessarily dependent; hence, Networking is interdisciplinary. The distinction between Networking and Computer Science in general is difficult to precisely define; it is better perhaps to consider that Networking grew out of Computer Science, because of a need to extend the existing capabilities of a computer (which includes data transmission) across large distances and with other unlike systems. However, an extensive background in Computer Science is not necessary to study or even practice Networking. A Network Engineer is a qualified individual who works with networks of some form, but the scope of that work and the skills required may be as diverse - even from one job to the next - as those of any scientist.

Networking is the practice of enabling and harnessing the transmission of data from one computer system to another, and can be divided into three categories:

• Connectivity Concepts - The principles and methods devices use to communicate over a network
• Mediums - The actual, physical method used to communicate.
• Administration - The process of maintaining a network.
