Step-by-step explanation:
A server is a deployable software package that can provide services to its clients. It acts as a central hub that receives requests from clients and responds with the requested information or functionality. Servers can handle various types of requests, such as web pages, file transfers, email, database access, and more.
For example, a web server is a type of server that serves web pages to clients upon request. It stores the web content and delivers it to users' browsers when they access a website. Another example is an email server, which handles the sending, receiving, and storage of email messages.
Servers can run on different operating systems, such as Windows Server, Linux, or macOS Server. They can be physical machines or virtualized instances running on cloud platforms like Amazon Web Services (AWS) or Microsoft Azure.
