2.Common Internet protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol). TCP/IP is a stream protocol. This means that a connection is negotiated between a client and a server.
3.ISPs allow users access to networks that contain the required equipment, enabling users to establish Internet connectivity. ISPs are responsible for making sure you can access the Internet, routing Internet traffic, resolving domain names, and maintaining the network infrastructure that makes Internet access possible.
4.The web browser connects to the web server and sends an HTTP request (via the protocol stack) for the desired web page. The web server receives the request and checks for the desired page. If the page exists, the web server sends it. If the server cannot find the requested page, it will send an HTTP 404 error message.
5.Sending and receiving email.
