What can be a criteria to choose a web host? Then the answer is a web host is a service provider that places your web site on a computer which is connected to the internet. The term for this 'computer' is called a server. A web hosting provider will typically have a fast connection to the Internet and they may host thousands of web sites on many servers. The web host essentially rents out space to you so that you can get your website up on the world wide web.
The main feature a better web host should contain Control Panel is an interface where you can access your site on the web server, allowing you to set-up and subsequently update and customize your web site. Though cPanel is by far the most popular control panel, some hosting providers customize their own so that they can up-grade and expand it at will.
A vast majority of sites that don't have tons of graphics, sound and video clips or downloadable files easily fit in 50 MB of disk space. You should always leave yourself some room for growth or check if the host has a bigger plan in case you need to upgrade.
So on this basis you can select a host.
