About instant Messenger

AOL Instant Messenger by America Online

An easy to use Instant Message program is AOL Instant Messenger (AIM). It allows you to have conversations with people who are also online, in real time, one on one, in a chat room, all across the globe. All you have to do is type what you would like to say. With this program you can keep track of your friends and even organize them into different groups. This way you can stay in touch with friends, family, and even coworkers.

MSN Messenger & Windows Live Messenger By Microsoft

MSN Messenger (known as MSN) is a program used to communicate with other MSN Messenger users in real time

Yahoo! Messenger by Yahoo!

Yahoo! Messenger, also known as YIM, also known as Yahoo! Instant Messenger and also known as Yahoo! Pager is of course, an attempt by Yahoo! to compete in the Instant Messaging game.

ICQ by Mirabilis.

ICQ (I Seek You) is the first Instant Messaging program. It was invented by two Israeli Students in Tel Aviv and AOL currently owns ICQ.

Google Talk by Google Inc.

The newest of all messengers is Google Talk. It is a messaging and voice program that does not have avatars, smilies annoying typing sounds, colorful or large chat text or anything I never liked about most messengers

Trillian by Cerulean Studios

Trillian is a pretty heavy piece of software for a Chat client. Keeping in mind that it supports connections from AOL Instant Messenger, ICQ, MSN Messenger, Yahoo! Instant Messenger, IRC and probably a lot more, Trillian seems pretty light to be carrying all that around.

Skype by Skype Technologies S.A.

I kept seeing the code callto://name on an increasing number of sites and blogs, some even with a "Skype Me!" button. This URL syntax was used for Microsoft Net meeting calling and hardly seen online, but had re-emerged with the more popular software called Skype - now with over one hundred million downloads.

Gaim (Now Pidgin) by Gaim

guess I wasn't hip enough to know about one of the most popular new messengers. I had to be told about Gaim.

What is the Registry

The Registry is a database used to store settings and options for the 32 bit versions of Microsoft Windows including Windows 95, 98, ME and NT/2000. It contains information and settings for all the hardware, software, users, and preferences of the PC. Whenever a user makes changes to a Control Panel settings, or File Associations, System Policies, or installed software, the changes are reflected and stored in the Registry.
The physical files that make up the registry are stored differently depending on your version of Windows; under Windows 95 & 98 it is contained in two hidden files in your Windows directory, called USER.DAT and SYSTEM.DAT, for Windows Me there is an additional CLASSES.DAT file, while under Windows NT/2000 the files are contained seperately in the %SystemRoot%\System32\Config directory. You can not edit these files directly, you must use a tool commonly known as a "Registry Editor" to make any changes (using registry editors will be discussed later in the article).

Search Engine Motors

Googlehttp://www.google.com/
Google has a well-deserved reputation as the top choice for those searching the web. The crawler-based service provides both comprehensive coverage of the web along with great relevancy. It's highly recommended as a first stop in your hunt for whatever you are looking for.
AllTheWeb.comhttp://www.alltheweb.com/
An excellent crawler-based search engine, All The Web provides both comprehensive coverage of the web and outstanding relevancy. If you tried Google and didn't find it, All The Web should probably be next on your list. Indeed, it's a first stop search engine, for some. In addition to web page results, AllTheWeb.com provides the ability to search for news stories, pictures, video clips, MP3s and FTP files.
Yahoohttp://www.yahoo.com/
Launched in 1994, Yahoo is the web's oldest "directory," a place where human editors organize web sites into categories. However, in October 2002, Yahoo made a giant shift to using Google's crawler-based listings for its main results.
MSN Searchhttp://search.msn.com/
Microsoft is known for constantly reworking its software products until they get them right, and MSN Search is a shining example of the company putting that same effort into an online product. In particular, the company has its own team of editors that monitors the most popular searches being performed and then hand-picks sites that are believed to be the most relevant. After performing a search, "Popular Topics" shown below the search box on the results page are also suggestions built largely by editors to guide you into making a more refined search. When appropriate, search results may also feature links to encyclopedia content from Microsoft Encarta or news headlines, at the top of the page.
Strongly Consider
The search engines below are other good choices to consider when searching the web.
AOL Searchhttp://aolsearch.aol.com/ (internal)http://search.aol.com/(external)
AOL Search provides users with editorial listings that come Google's crawler-based index. Indeed, the same search on Google and AOL Search will come up with very similar matches. So, why would you use AOL Search? Primarily because you are an AOL user. The "internal" version of AOL Search provides links to content only available within the AOL online service. In this way, you can search AOL and the entire web at the same time. The "external" version lacks these links.Why wouldn't you use AOL Search? If you like Google, many of Google's features such as "cached" pages are not offered by AOL Search.
Ask Jeeveshttp://www.askjeeves.com/
Ask Jeeves initially gained fame in 1998 and 1999 as being the "natural language" search engine that let you search by asking questions and responded with what seemed to be the right answer to everything.
HotBothttp://www.hotbot.com/
HotBot provides easy access to the web's four major crawler-based search engines: AllTheWeb.com/FAST, Google, Inktomi and Teoma, all of which are described elsewhere on this page.Nevertheless, it's a fast, easy way to get different web search "opinions" in one place.
Lycoshttp://www.lycos.com/
Lycos is one of the oldest search engines on the web, launched in 1994. It ceased crawling the web for its own listings in April 1999 and instead uses crawler-based results provided by AllTheWeb.
Teomahttp://www.teoma.com/
Teoma is a crawler-based search engine owned by Ask Jeeves. It has a smaller index of the web than its rival crawler-competitors Google, AllTheWeb.com, Inktomi and AltaVista.

About Search Engine

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 Google, Alta Vista and Excite that enable users to search for documents on the World Wide Web and USENET newsgroups.
Typically, a search engine works by sending out a spider to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Each search engine uses a proprietary algorithm to create its indices such that, ideally, only meaningful results are returned for each query.

PageRank
Main article: PageRank
Google's algorithm uses a patented system called PageRank to help rank web pages that match a given search string.[5] The PageRank algorithm computes a recursive score for web pages, based on the weighted sum of the PageRanks of the pages linking to them. The PageRank derives from human-generated links, and is thought to correlate well with human concepts of importance. The exact percentage of the total of web pages that Google indexes is not known, as it is very hard to actually calculate. Previous keyword-based methods of ranking search results, used by many search engines that were once more popular than Google, would rank pages by how often the search terms occurred in the page, or how strongly associated the search terms were within each resulting page. In addition to PageRank, Google also uses other secret criteria for determining the ranking of pages on result lists, reported to be a number over 200.[6]

Search results
Google not only indexes and caches web pages but also takes "snapshots" of other file types, which include PDF, Word documents, Excel spreadsheets, Flash SWF, plain text files, online videos such as YouTube and much more.[7] Except in the case of text and SWF files, the cached version is a conversion to (X)HTML, allowing those without the corresponding viewer application to read the file.
Users can customize the search engine, by setting a default language, using the "SafeSearch" filtering technology and set the number of results shown on each page. Google has been criticized for placing long-term cookies on users' machines to store these preferences, a tactic which also enables them to track a user's search terms and retain the data for more than a year. For any query, up to the first 1000 results can be shown with a maximum of 100 displayed per page.I was here!!
