Server on a computer network
A server on a computer network is a computer or program that manages network resources and provides services to other computers or clients on the network. It serves as a central hub for data storage, communication, and processing.
Servers can be dedicated hardware devices or software applications running on a regular computer. They are typically more powerful and have more resources than regular client computers.
Common types of servers on a computer network include:
1. File Server: Stores and manages files, allowing users to access and share them.
2. Print Server: Controls network printers, enabling multiple users to print to them.
3. Web Server: Hosts websites and delivers webpages to clients over the internet.
4. Application Server: Runs applications and provides services, such as database access, to client computers.
5. Mail Server: Handles sending, receiving, and storing email messages.
6. DNS Server: Translates domain names to IP addresses, helping with internet communication.
7. DHCP Server: Assigns IP addresses to client computers on the network.
8. Proxy Server: Acts as an intermediary between client devices and the internet, providing services like caching and content filtering.
These servers communicate with clients through the network using specific protocols. They often have higher security measures and are monitored to ensure proper functioning and to protect the network and its data.
