What Is a Server?
A server is a high-performance computing device or system that provides data, services, programs, or resources to other computers (known as clients) over a network. Unlike regular personal computers, servers are set up for reliability, uptime, scalability, and handling large volumes of data or numerous simultaneous connections.
Servers can be physical (bare metal) or virtual (VMs) and are used to host websites, operate databases, run applications, process emails, store files, and provide basic services in IT infrastructure.
What Does a Server Do? (Primary Functions)
• Data Storage and Access: Centralized file, document, and backup storage with controlled access permissions
• Application Hosting: Hosting business-critical applications (e.g., ERP, CRM, email services)
• Database Management: Hosting and managing relational and NoSQL databases
• Web Hosting: Hosting web content for users over the internet or intranet
• Virtualization: Hosting several virtual machines using hypervisors
• Authentication & Directory Services: User, role, policy management (e.g., using Active Directory or LDAP)
• Remote Access: Allowing secure connections to internal systems from external devices
