In case you host your internet sites on a dedicated hosting server, you would expect that they'll perform super fast and that the access speed to them shall depend entirely on the Internet connection of the site visitors. Nevertheless, this will not be the case if the server has lousy network connectivity or relies on a network card, which just can't cope with high volume of website traffic. If this is the situation, it shall take a while for your internet sites to load if a lot of people open them at the same time or visitors may see error messages. Thus you might lose website visitors as probably many people will never revisit your internet site if they have experienced difficulties or slow loading speeds. This is the reason why you need to pay attention to the network components of any new hosting server you purchase and not just to the main hardware such as Processor, RAM or hard drive.
