3: Another reference model for network communication, the OSI model, was created in 1984 by the International Organization for Standardization (ISO). Unlike the TCP/IP model, which focuses on the TCP and IP protocols used on the Internet, the OSI model divides all network communication (not just TCP/IP) into seven layers. The OSI seven-layer model provides the same benefits of standardization and independent compatibility as mentioned previously for the TCP/IP layered model. Table 30-2 describes the OSI model and the associated protocols and PDUs for each layer.

This cloud represents the hierarchy of devices that connect you to other networks and the Internet. ISPs sit at the top of this hierarchy and connect to each other through Internet exchange points (IXP) or network access points (NAP). These IXPs and NAPs between ISPs provide the backbone for the Internet. 舡 This Internet backbone is typically connected with fiber-optic cable installed underground and even undersea. The connections between continents are handled by tier 1 ISPs. The intermediary connections between countries are classified as tier 2 ISPs.

The range for these well-known or registered ports is 0 to 1023; applications use these ports as destination ports. However, a client dynamically selects a port as the source of the communication from the port range 1024 to 65535. An example is a web browser that requests a web page. The browser would use port 80 as the destination port (the typical web server port) and would choose a dynamic port in the higher range to list as the source port for return communication. As mentioned previously, the combination of a port and Layer 3 IP address creates a socket.
