Answer Key

Purpose of HTTP

Section A: Quick Questions

B — Hypertext Transfer Protocol

A — Rules for a browser and web server to request and send web pages

B — It is used only for web pages

A — HTTP

A — Web pages containing hypertext and links

Section B: Match the Pairs

HTTP → Hypertext Transfer Protocol: the rules a browser and web server use to request and send web pages

http://www.example.com/index.html → A URL that starts with the default protocol for web pages, telling the browser to use HTTP to fetch the page

HTTP is used for the web only: it transfers web pages, not emails → HTTP = web pages

The browser asks the web server for a page using HTTP → GET /index.html HTTP/1.1

HTTP = Hypertext Transmission Program → HTTP stands for Hypertext Transfer Protocol. It is a protocol (a set of rules), not a program.

HTTP is used to send emails and transfer files of any kind → HTTP is used only for web pages. Email and other services use different protocols.

Section C: Definitions

HTTP — Hypertext Transfer Protocol: the set of rules a browser and web server use to request and send web pages. It is the default protocol for the web and is used only for web pages.

Section D: Fill in the Blanks

http://www.example.com/index.html

GET /index.html HTTP/1.1

Browser sends an HTTP request to server

Server sends an HTTP response to browser

HTTP stands for Hypertext Transfer Protocol

Section E: Spot the Error

A — The acronym for Hypertext Transfer Protocol is HTTP. HTML is the markup language used to build web pages, not a protocol.

D — The server sends the web page in its HTTP response. The browser only displays it, so line 4 should be: browser displays the web page.

C — HTTP is used only for requesting and sending web pages, not for email. The line should print 'web pages only'.

A — A browser requesting a web page names the HTTP protocol in the request line. It should say HTTP/1.1, not FTP/1.1.

B — HTTP is the default protocol for web pages. SMTP is used for sending email, so the value should be 'HTTP'.
