helpdesk - kow more

A helpdesk is an information and assistance resource that troubleshoots problems with computers or similar products. Corporations often provide helpdesk support to their customers via a toll-free number, website and/or e-mail. There are also in-house helpdesks geared toward providing the same kind of help for employees only. Some schools offer classes in which they perform similar asks as a helpdesk. In the Information Technology Infrastructure Library, within companies adhering to ISO/IEC 20000 or seeking to implement IT Service Management best practice, a helpdesk may offer a wider range of user centric services and be part of a larger Service Desk.

Functions : A typical helpdesk has several functions. It provides the users a central point to receive help on various computer issues. The helpdesk typically manages its requests via helpdesk software, such as an incident tracking system, that allows them to track user requests with a unique ticket number. This can also be called a "Local Bug Tracker" or LBT. The helpdesk software can often be an extremely beneficial tool when used to find, analyze, and eliminate common problems in an organization's computing environment. The user notifies the helpdesk of his or her issue, and the helpdesk issues a ticket that has details of the problem. If the first level support technician is able to solve the issue, the ticket is closed and updated with documentation of the solution to allow other helpdesk technicians to reference in the future. If the issue needs to be escalated, it will be updated, noting what was attempted by the technician and dispatched to second level support. There are many software applications available to support the helpdesk function. Some are targeting enterprise level helpdesk (rather large) and some are targeting departmental needs. From the mid 1990s research by Middleton at The Robert Gordon University found that many organizations had begun to recognize that the real value of their helpdesk(s) derives not solely from their reactive response to users' issues but from the helpdesk's unique position where it communicates daily with numerous customers or employees. This gives the helpdesk the ability to monitor the user environment for issues from technical problems to user preferences and satisfaction. Such information gathered at the helpdesk can be valuable in planning and preparation to other units in IT as well as non-IT departments such as sales and product development.

google ad sense - money making made simplified over the internet

AdSense is an advertisement serving program run by Google. Website owners can enroll in this program to enable text, image, and more recently, video advertisements on their websites. These advertisements are administered by Google and generate revenue on either a per-click or per-impression basis. Google is also currently beta-testing a cost-per-action based service.

Working

The webmaster inserts the AdSense JavaScript code into a webpage. Each time this page is visited, the JavaScript code creates an IFrame with a src attribute set to the page's URL. For contextual advertisements, Google's servers use a cache of the page to determine a set of high-value keywords. If keywords have been cached already, advertisements are served for those keywords based on the AdWords bidding system. (More details are described in the AdSense patent.) . For site-targeted advertisements, the advertiser chooses the page(s) on which to display advertisements, and pays based on cost per mille (CPM), or the price advertisers choose to pay for every thousand advertisements displayed. For referrals, Google adds money to the advertiser's account when visitors either download the referred software or subscribe to the referred service. The referral program will be retired in August 2008. Search advertisements are added to the list of results after the visitor performs a search. Because the JavaScript is sent to the Web browser when the page is requested, it is possible for other website owners to copy the JavaScript code into their own webpages. To protect against this type of fraud, AdSense customers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified. Some webmasters create websites tailored to lure searchers from Google and other engines onto their AdSense website to make money from clicks. These "zombie" websites often contain nothing but a large amount of interconnected, automated content (e.g., a directory with content from the Open Directory Project, or scraper websites relying on RSS feeds for content). Possibly the most popular form of such "AdSense farms" are splogs (spam blogs), which are centered around known high-paying keywords. Many of these websites use content from other websites, such as Wikipedia, to attract visitors. These and related approaches are considered to be search engine spam and can be reported to Google. A Made for AdSense (MFA) website or webpage has little or no content, but is filled with advertisements so that users have no choice but to click on advertisements. Such pages were tolerated in the past, but due to complaints, Google now disables such accounts. There have also been reports of Trojan horses engineered to produce counterfeit Google advertisements that are formatted to look like legitimate ones. The Trojan downloads itself onto an unsuspecting computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.

stock market - all you want to know

A stock market, or (equity market), is a private or public market for the trading of company stock and derivatives of company stock at an agreed price; these are securities listed on a stock exchange as well as those only traded privately. The size of the world stock market is estimated at about $51 trillion. The world derivatives market has been estimated at about $480 trillion face or nominal value, 30 times the size of the U.S. economy, and 12 times the size of the entire world economy. It must be noted though that the value of the derivatives market, because it is stated in terms of notional values, and cannot be directly compared to a stock or a fixed income security, which traditionally refers to an actual value. Many such relatively illiquid securities are valued as marked to model, rather than an actual market price. The stocks are listed and traded on stock exchanges which are entities a corporation or mutual organization specialized in the business of bringing buyers and sellers of stocks and securities together. The stock market in the United States includes the trading of all securities listed on the NYSE, the NASDAQ, the Amex, as well as on the many regional exchanges, e.g. OTCBB and Pink Sheets. European examples of stock exchanges include the London Stock Exchange, the Deutsche Borse and the Paris Bourse, now part of Euronext.
