Internet Questions with Solutions

The internet is a global network of networks that lets computers around the world communicate. This topic covers the World Wide Web and how it differs from the internet itself, web browsers and search engines, URLs and domain names, and the protocols that make the internet work, such as HTTP, HTTPS, FTP, SMTP, POP3, IMAP and DNS. It also covers email (its parts, CC and BCC), web pages and websites, HTML basics, internet service providers, cloud computing, and common terms such as IP address, bandwidth, cookies, cache, upload and download. Exam questions often ask what a protocol is used for, the full form of an abbreviation, or who invented the World Wide Web (Tim Berners-Lee). Remember that DNS translates domain names into IP addresses, and SMTP sends email while POP3 and IMAP receive it. Practise the internet questions below. Each answer includes an explanation.
