Here’s a short glossary of common web hosting terms used and accepted worldwide.
1.Web hosting service: A type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by 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 other servers located in their data center, called colocation, also known as Housing in Latin America or France.**
2.URL: A uniform resource locator (abbreviated URL; also known as a web address, particularly when used with HTTP) is a specific character string that constitutes a reference to a resource. Most web browsers display the URL of a web page above the page in an address bar. **A typical URL might look like:
http://www.example.org/wiki/Main_Page
3.SSL: Secure Sockets Layer, a protocol for encrypting information over the Internet.**
4.FTP: The File Transfer Protocol is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet.**
5.Shared Hosting: A shared web hosting service or virtual hosting service or derive host refers to a web hosting service where many websites reside on one web server connected to the Internet. Each site “sits” on its own partition, or section/place on the server, to keep it separate from other sites. This is generally the most economical option for hosting, as many people share the overall cost of server maintenance.**
6.Reseller Hosting: Reseller hosting is a form of web hosting wherein the account owner has the ability to use his or her allotted hard drive space and bandwidth to host websites on behalf of third parties. The reseller purchases the host’s services wholesale and then sells them to customers, possibly for a profit. A certain portion of hard drive space and bandwidth is allocated to the reseller account. The reseller may rent a dedicated server from a hosting company, or resell shared hosting services. In the latter case, the reseller is simply given the permission to sell a certain amount of disk space and bandwidth to their own customers without renting a server from a web hosting company they signed for a reseller account with.**
7.VPS: A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service. A VPS runs its own copy of an operating system, and customers have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS.**
8.Dedicated Hosting: A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone else. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc.**
