what is web hosting

Published on December 14, 2012 by   ·   No Comments

what is web hostingWeb hosting is the space where web pages or files are kept to make them  accessible on the world wide web. After designing a website, the files of the  site should be kept in a PC which is connected to the internet. This is called  web hosting & the PC having this space is called the server PC.

Types of Web Hosting: Web hosting is mainly categorized  based on the operating system of the server PC & performance.

Based on the OS of the server PC there are mainly two types of hosting -

1. Windows Hosting: The hosting where the  server PC is run on windows. Windows hosting is a perfect choice if you want to  use dotNET, ASP, access database & other Microsoft products. The main  limitation of it is that it gives limited access to Telnet, SSH, CGI, Perl  etc.

2. Linux Hosting: The hosting with linux  run server is called linux hosting. It is more popular than windows hosting for  it’s security, access to telnet, SSH, CGI, Perl etc, But if you want to work  with ASP, or access database, linux hosting is not for you.

Based on performance, resource (disk space, RAM, CPU) usage & user’s  access to the server, there are mainly three types of hosting -

1. Shared Hosting: This is the hosting  where some accounts are hosted on the same pc. In this hosting, all accounts  share the system resources like RAM, CPU, Disk Space etc together. Here you may  have a specific amount of disc space & bandwidth, but there is no guaranty  of systems resources. Sometimes you may get 60% of the system resources or  sometimes below 30%, which actually depends, on the resource usages of other  accounts on the same server at that time. In this hosting, users get the least  control over the server. They can only read/write files on the server and can’t  change any server settings.

2. VPS (Virtual Private Server) Hosting: VPS hosting is the  hosting where several accounts are hosted on the same PC but work as independent  PC. In a VPS, accounts have their own RAM, disk space, CPU etc so that the  performance of one account is not affected by others. Even if the resources of  an account are unused then it won’t be shared with others.

VPS gives users complete control over the server. In a VPS, users get full  control so that they can change any settings on the server or can install any  required software. Even they can reboot or shut down their server whenever they  want.

3. Dedicated Server Hosting: In respect to the  functionality, dedicated hosting is same as VPS hosting but in dedicated hosting  only one account is hosted in one pc. So when someone buys a dedicated hosting,  he actually rents a whole pc instead of part of it.

Dedicated hosting is the best choice for high traffic sites & sites with  complex functionality like ecommerce sites or database driven big sites.

For hosting a website, it is possible to set up a server on your own pc &  host sites there, but it’s a complex process & requires high performance PC  with high speed & reliable internet connection. It also requires running  that PC 24 hours a day to avoid downtime. This is why it’s recommended to buy  hosting services from professional hosting providers.
