Introduction to Web Servers
A web server is a software application or hardware device that hosts, manages, and delivers web content over the internet. Its primary function is to store, process, and serve web pages to clients, such as web browsers, that request them. Web servers operate on a client-server model, where the client (usually a web browser) initiates a request for a web page, and the server responds by sending the requested page. Web servers can be categorized into two main types: dedicated and shared. A dedicated web server is exclusively allocated to a single website or application, ensuring full control and customization, whereas a shared web server hosts multiple websites, making it a more economical option but with limited control and potential performance issues.
Key Characteristics of Web Servers
Some key characteristics of web servers include:
– Static Content Serving: Web servers are adept at serving static content such as images, videos, and HTML files directly from storage.
