FTP (file transfer protocol) is a convenient way of uploading and downloading files to and from a server. This requires a program like FileZilla (available free on the net) that you install on your local computer. But you can also use your browser to transfer files by FTP, although it is not as handy as an FTP program. Another advantage of FTP is that file transfer is lightning quick. You can also assign dedicated access rights. An FTP server is available to you, even with a VPS.
All of these features may look impressive, but if you don't know what Dedicated Hosting is in the first place, these features probably don't matter much to you at all. When you purchase a Dedicated Server from A2 Hosting, you are getting all of the resources listed with the server plan of your choice. You do not share these resources with any other user or customer. The bandwidth, RAM and data transfer are for your use exclusively. With all of these resources at your disposal, you can expect your hosting service to be both highly reliable with top performance.
