Web hosting is a service which allocates space for customers to showcase their websites on computer servers that are connected to the Internet 24/7.
Servers are powerful computers that have extremely large hard drives, or an array of hard drives. Space is then rented to those who want a "website presence" on the Internet.
Every server on the Internet has a unique numerical IP (Internet Protocol) address. You can think of servers as apartment buildings with unique addresses. Each apartment unit within each building is equivocal to space rented out for individual websites. And like real apartment buildings, each unit also has an address based on "the building" in which it is located.
When you rent a space on a server then, you're setting up house on the Internet. You can be reached by a unique address (the website address), which is based on the server's address.
There are many different types of web hosting. Most packages come with certain capabilities for users. Examples are scripts that allow interactive functions, forms, bulletin boards, guest books, etc. For professional purposes there are also Web hosting services that offer commercial packages that bundle business tools, like point of sales packages and credit card processing.
Prices for Web hosting vary from free to hundreds of dollars a year, depending on your needs. Web hosting for personal websites that don't require any special tools and have low traffic (not a high number of viewings) can be found easily for free.
Free Web hosting is convenient but has its drawbacks. Usually it will be required that you allow the server to run advertisements on your website. The advertisements are normally banner ads -- a banner at the top of the page for example -- and sometimes pop-up ads as well. Most free hosting services offer an alternative pay-plan to have the advertisements removed.
Another consideration is that free services normally allocate your website address as an extension of the server's address. For example: www.thewebhost.com/yourwebsite. If you want an address like: www.yourwebsite.com, you will have to pay to register your own domain name.
There are other considerations when looking for a Web host aside from price. Some hosting services have policies that restrict certain content, scripting languages, functions or uses. You should also read the privacy policy of any hosting service that you are considering, to see how they will use the personal information you provide to them in setting up your account.

What is Forex?
FOREX - the foreign exchange market or currency market or Forex is the market where one currency is traded for another. It is one of the largest markets in the world.
Some of the participants in this market are simply seeking to exchange a foreign currency for their own, like multinational corporations which must pay wages and other expenses in different nations than they sell products in. However, a large part of the market is made up of currency traders, who speculate on movements in exchange rates, much like others would speculate on movements of stock prices. Currency traders try to take advantage of even small fluctuations in exchange rates.
In the foreign exchange market there is little or no 'inside information'. Exchange rate fluctuations are usually caused by actual monetary flows as well as anticipations on global macroeconomic conditions. Significant news is released publicly so, at least in theory, everyone in the world receives the same news at the same time.
Currencies are traded against one another. Each pair of currencies thus constitutes an individual product and is traditionally noted XXX/YYY, where YYY is the ISO 4217 international three-letter code of the currency into which the price of one unit of XXX currency is expressed. For instance, EUR/USD is the price of the euro expressed in US dollars, as in 1 euro = 1.2045 dollar.
Unlike stocks and futures exchange, foreign exchange is indeed an interbank, over-the-counter (OTC) market which means there is no single universal exchange for specific currency pair. The foreign exchange market operates 24 hours per day throughout the week between individuals with forex brokers, brokers with banks, and banks with banks. If the European session is ended the Asian session or US session will start, so all world currencies can be continually in trade. Traders can react to news when it breaks, rather than waiting for the market to open, as is the case with most other markets.
Average daily international foreign exchange trading volume was $1.9 trillion in April 2004 according to the BIS study.
Like any market there is a bid/offer spread (difference between buying price and selling price). On major currency crosses, the difference between the price at which a market maker will sell ("ask", or "offer") to a wholesale customer and the price at which the same market-maker will buy ("bid") from the same wholesale customer is minimal, usually only 1 or 2 pips. In the EUR/USD price of 1.4238 a pip would be the '8' at the end. So the bid/ask quote of EUR/USD might be 1.4238/1.4239.
This, of course, does not apply to retail customers. Most individual currency speculators will trade using a broker which will typically have a spread marked up to say 3-20 pips (so in our example 1.4237/1.4239 or 1.423/1.425). The broker will give their clients often huge amounts of margin, thereby facilitating clients spending more money on the bid/ask spread. The brokers are not regulated by the U.S. Securities and Exchange Commission (since they do not sell securities), so they are not bound by the same margin limits as stock brokerages. They do not typically charge margin interest, however since currency trades must be settled in 2 days, they will "resettle" open positions (again collecting the bid/ask spread).
Individual currency speculators can work during the day and trade in the evenings, taking advantage of the market's 24 hours long trading day.

Web hosting service

A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own or lease for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation.
Service scope
The scope of hosting services varies widely. The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web "as is" or with little processing. Many Internet service providers (ISPs) offer this service free to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or cheap. Business web site hosting often has a higher expense.
Single page hosting is generally sufficient only for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, Ruby on Rails, ColdFusion, and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management. For e-commerce, SSL is also highly recommended.
The host may also provide an interface or control panel for managing the Web server and installing scripts as well as other services like e-mail. Some hosts specialize in certain software or services (e.g. e-commerce). They are commonly used by larger companies to outsource network infrastructure to a hosting company.
Hosting reliability and uptime
| | This section does not cite any references or sources. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (March 2009) |
Hosting uptime refers to the percentage of time the host is accessible via the internet. Many providers state that they aim for at least 99.9% uptime (roughly equivalent to 45 minutes of downtime a month, or less), but there may be server restarts and planned (or unplanned) maintenance in any hosting environment, which may or may not be considered part of the official uptime promise.
Many providers tie uptime and accessibility into their own service level agreement (SLA). SLAs sometimes include refunds or reduced costs if performance goals are not met.
