Web hosting involves providing space on a server for websites. Linux is commonly used for hosting due to its maintainability and performance. A web server software like Apache is installed to handle HTTP requests from browsers. URLs identify resources on the web using protocols like HTTP and FTP. CGI scripts allow dynamic content generation but pose security risks. Load balancing distributes server load across multiple systems. Choosing a server depends on factors like robustness, performance, updates, and cost. Apache is widely used and configurable using configuration files that control server parameters, resources, and access restrictions. Virtual interfaces allow a single server to host multiple websites. Caching and proxies can improve performance and security. Anonymous FTP allows public file downloads.
