Web page (or webpage) is a specific collection of information provided by a website and displayed to a user in a web browser.
A website typically consists of many web pages linked together in a coherent fashion.
The name "web page" is a metaphor of paper pages bound together into a book.
Website:
A website (also written as a web site) is a collection of web pages and related content that is identified by a common domain name and published on atleast one web server.
A group of related web pages forms a website.
Notable examples are wikipedia.org, google.com, and amazon.com. All publicly accessible websites collectively constitute the World Wide Web.
Proxy server:
A proxy server is a computer system or router that functions as a relay between client and server.
It helps prevent an attacker from invading a private network and is one of several tools used to build a firewall.
The word proxy means "to act on behalf of another," and a proxy server acts on behalf of the user.
All requests to the Internet go to the proxy server first, which evaluates the request and forwards it to the Internet. Likewise, responses come back to the proxy server and then to the user.
Home page:
The home page is a webpage that serves as the starting point of the website.
It is the default webpage that loads when you visit a web address that only contains a domain name.
The home page is located in the root directory of a website.
Most web servers allow the home page to have one of several different filenames.
Web server:
A web server is a computer that runs websites.
It is a computer program that distributes web pages as they are requisitioned.
The basic objective of the web-server is to store, process, and deliver web pages to the users.
This intercommunication is done using Hypertext Transfer Protocol (HTTP).
