虚拟主机是提供用于存储网页的在线空间的服务。这些网页可通过万维网获得。提供网站托管的公司称为Web托管。

托管网站的服务器保持24 x7开机状态。这些服务器由网络托管公司运行。每个服务器都有自己的IP地址。由于IP地址很难记住，因此，网站管理员会将其域名指向其网站所存储的服务器的IP地址。

您的网站无法托管在本地计算机上，因此您必须每天24小时离开计算机。这是不实际的并且便宜。这是网络托管公司出现的地方。

下表描述了根据需要可以使用的不同类型的主机：

S.N.	Hosting Description
1.	Shared Hosting In shared hosting, the hosting company puts thousand of website on the same physical server. Each customer has their own allocation of physical web space and a set of bandwidth limit. As all websites share same physical memory, MYSQL server and Apache server, one website on the server experiencing high traffic load will affect performance of all websites on the server.
2.	Virtual Private Server (VPS) It is also known as Virtual Dedicated Server. It is a server which is partitioned into smaller servers. In this customer is given their own partition, which is installed with its own operating system. Unlike shared hosting, VPS doesn’t share memory or processor time rather it allocates certain amount of memory and CPU to use which means that any problem on a VPS partition on the same drive will not affect other VPS customers.
3.	Dedicated Server In this kind of hosting, single dedicated server is setup for just one customer. It is commonly used by the businesses that need the power, control and security that a dedicated server offers.
4.	Reseller Hosting A reseller acts as a middle man and sells hosting space of someone else’s server.
5.	Grid Hosting Instead of utilizing one server, Grid Hosting spreads resources over a large number of servers. It is quite stable and flexible. The servers can be added or taken away from the grid without crashing the system.
