Internet: The Internet is a massive publically availible global network of devices interconnected to each other via protocols.
Many different protocols are used to transfer data between devices connected to the Internet.
Ill try to explain a few of the key protocols used for browsing the web using the least amount of networking lingo I can:
Internet Protocol: Every devices connected to the internet has a unique I.P (Internet Protocol) address to determine the location of the device on the network. For example even the server that hosts www.teamtreehouse.com has an I.P address (173.247.98.20). (Try it now yourself put 173.247.98.20 into your web browser address bar and you should be directed to teamtreehouse)
DNS Protocol: When you go to a website for example teamtreehouse.com your browser uses DNS (Domain Name System) protocol to connect to a DNS server to translate the simplified web address into it's original I.P address.
HTTP: HTTP (Hypertext Transfer Protocol) is the protocol that the WWW (World Wide Web, The Web) uses to transfer HyperText data across networks such as the Internet, Local Intranet and partially public Extranets. When you go to a website for example www.teamtreehouse.com, first your browser requests the I.P address for www.teamtreehouse.com from a DNS server, once your browser has the I.P address of the server it sends a HTTP request to the server, without going into too complicated networking, basically the server returns an HTTP header response with information about what is contained at the address, your browser and the server will bounce back and fourth with HTTP requests until the data matches the HTTP header sent from the server (it's a bit more complicated than this and involves more protocols from your router to the server to determine that the data recieved is correct and not corrupt but this is the basic idea of how it works)
World Wide Web: The World Wide Web (WWW) basically refers to the global web of hypertext files connected to eachother via hyperlinks using the HTTP Protocol on the Internet Network.
List of Internet Protocols:
WIFI/WIMAX Protocols
Bluetooth protocol
Fibre Channel network protocols
Internet Protocol Suite or TCP/IP model or TCP/IP stack
OSI protocols family of information exchange standards developed jointly by the ISO and the ITU-T Routing protocols
List of IP protocol numbers, protocol numbers used in the Protocol field of the IPv4 header and the Next Header field of IPv6 header
Yahoo! Messenger, underlying protocol used by the Yahoo messenger
RTPS protocol, an interoperability protocol
SSH Secure Shell
SMB Server Message Block, one version of which was also known as CIFS (Common Internet File System)
FTP File Transfer Protocol
SMTP Simple Mail Transfer Protocol
TCP Transmission Control Protocol
Telnet Telephone Network
HTTP Hyper Text Transfer Protocol
HTTPs Secure Hyper Text Transfer Protocol
POP Post Office Protocol
HTCPCP Hyper Text Coffee Pot Control Protocol
MTP Media Transfer Protocol
SFTP Secure File Transfer Protocol
SSL Secure Socket Layer
TLS Transport Layer Security
E6 Ethernet globalization protocols
NTP Network time protocol
PPP Point to Point Protocol
NNTP Network News Transfer Protocol
QOTD Quote Of The Day
IMAP Internet Message Access Protocol
Bitcoin Protocol Protocol for Bitcoin transactions and transfers on the web

The web (short for world wide web) is an information sharing system that uses a client/server model and a specific protocol (HTTP), and relies on the internet for connectivity.
So in short, when you use the web you are using the internet, but there's more to the internet than the web.
