A dedicated server is a type of hosting service where an entire physical server is reserved for a single user or organization. This means that all the server's resources, such as CPU, RAM, and storage, are exclusively available to that user, providing enhanced performance and reliability. Dedicated servers are often used for websites or applications that require high levels of traffic and resource allocation. These servers offer greater control and customization compared to shared hosting, where multiple users share the same server. Users can install specific software, configure security settings, and optimize performance according to their needs. This makes dedicated servers ideal for businesses, gaming, and large-scale applications that demand consistent uptime and speed.
