VPS stands for Virtual Private Server. It is a virtualized server that mimics a dedicated server within a shared hosting environment. A VPS runs its own operating system and provides the user with superuser-level access, allowing them to install and run almost any software that runs on that OS.

Dedicated Servers have various uses, including hosting large websites and applications, running complex databases, providing high-performance computing, hosting game servers, supporting high volumes of user traffic, and handling data backup and storage. Due to their high performance, reliability, and flexibility, Dedicated Servers are widely used in scenarios that require stability, security, and efficient operation.

A Dedicated Server is a physical server exclusively used by a single user, offering high performance, full resource control, and isolation, but at a higher cost. On the other hand, a Virtual Private Server (VPS) is created by partitioning a physical server using virtualization technology, providing multiple virtual server instances with independent resources and operating systems, at a lower cost and with some degree of isolation, suitable for users requiring more flexibility and control.
