A virtualized server combines physical hardware that is broken down into separate systems with the help of software. These servers can then be used and shared by several users. The resources available in the actual server (CPU, RAM, and memory) are divided.
Dedicated servers are servers that the customer receives as a whole. Comparable to a laptop or a home PC, the installed resources/components/hardware (CPU, RAM, memory, network access, etc.) are available for the exclusive use of one user.
