There are a lot of things you should know about dedicated server hosting, but the most important thing that should be mentioned first and foremost is that you need to buy your server. It is not enough for you to get shared server wmq hosting from any hosting company since those servers belong to the host, which means that there would be some other person using that server, too (usually).
So before you decide on getting 1gbps dedicated server for yourself, it would be best to do your homework well and to see what features you need to look for. Also, note that there are different types of server hosting so you should have a basic understanding of how each type works and what its features are before making a decision one way or another.
The most basic but still very important thing you should know about dedicated server hosting is that it is a managed hosting service where you will be running your software and operating system from that single server. Also, note that there are many types of hosting, but not all of them are managed to host. For instance, there is self-managed hosting where you will be running everything on your own. Also, note that this type of hosting is usually only for people who are very knowledgeable with computer systems and who can easily take charge of the operation of the server.
Also note that there are different levels of managed server hosting, ranging from shared, reseller, virtual, dedicated, and grid hosting. Depending on the type of server you choose, you may also have access to such things as mail servers, data centers, backup utilities, databases, etc. If you want to know more about these features, then it would be best for you to look around and ask some questions from people who already use this type of hosting. This will give you a better understanding of what you should expect from your server and what you should avoid.
