Web hosting services are powered by computers that are connected to the internet 24/7/365. Those computers are called servers. Shared web hosting is the most popular service because it is the most economical way to publish a website online. In shared hosting, multiple sites utilize the physical resources of a single computer (server). This is where most of the disadvantages of the service come from. If you happen to have a bad neighbor on the server (another website), it may slow down your website at times, get your IP blacklisted, or even open security issues risking the safety of your own site and data.
