Server hardware refers to the physical components that make up a server, which is a powerful computer designed to manage network resources and provide services to other computers. Key components include the central processing unit (CPU), memory (RAM), storage drives, and motherboard. These elements work together to ensure the server can handle multiple tasks and users simultaneously. In addition to these core components, server hardware often includes specialized features such as redundant power supplies for reliability and cooling systems to prevent overheating. Servers can be housed in rack-mounted enclosures or as standalone units, depending on the needs of the organization.
