Bluehost offers unlimited bandwidth, storage and support for an unlimited number of websites with all of its shared hosting plans except for the cheapest one. With Basic, you only get 50 GB of storage and support for a single website. Despite the cheap price, I would recommend skipping Basic unless you’re a Blogger because you’ll get better value with the other three packages, especially Choice Plus during your first term.
That means that, even though there may be multiple virtual machines on the same physical server, you are in an isolated environment with dedicated resources (RAM, Storage) and virtually allocated CPUs that no one else can touch. Plus, with root access, you can make technical changes that would not be allowed on a shared hosting plan. You get the advanced performance, control and flexibility usually reserved for dedicated servers, but at a much lower price.
