Network connectivity defines a couple of things - exactly how many people shall be able to look at a given site concurrently and how fast they'll be able to perform that. In case the connection capacity is small, for example, the maximum throughput could be hit with just several visitors looking at the Internet site, so newcomers will be unable to gain access to the pages, or in another scenario, all site visitors could have difficulties. In case the capacity is enough, but the web server access speed is lower, it will take longer for any web page on the site to load and this may lead to visitors simply closing the website, if they notice that they need to wait for a minute or two just to view a number of pages. In this light, if you wish to launch and maintain a successful presence online, the web server in which you host your site should offer both fantastic access speeds and large traffic capacity.
