A website is a collection of web pages, images, videos or other digital assets that are hosted on one web server, usually accessible via the Internet.
A website may be organized by function as a personal website, a commercial website, organization website etc
A static website is one that has web pages stored on the server in the same form as the user will view them. It is primarily coded in HTML (Hyper-text Markup Language).
A dynamic website is one in which the web page content changes automatically and/or frequently based on certain criteria. The user/ administrator can add/modify content without any technical knowledge.
Domain names war unique alphabetical addresses instead of numeric ones. Domain names allow Internet users to more easily find and communicate with web sites and any other IP-based communications services.
