Web publishing involves creating and uploading websites, webpages, blogs, and other content to the internet. It requires web development software, an internet connection, and a web server. Content is uploaded to the web server via the internet connection. Web servers can be shared, hosting multiple sites, or dedicated to a single site. Domain names provide the address for websites and must be purchased separately from web hosting. Nameservers help connect domain names to server IP addresses through the domain name system.
