I Concepts & Terms Required - Chapter 0101
In this chapter, we will look at
TCP/IP in detail. First, we’ll examine how addressing works, then
we’ll look at how it’s made easier by use of name services.
After that, we’ll look at how TCP/IP is routed from network to
network. Once we know how packets get from place to place, we’ll
look at the standard TCP/IP services (application functions like sending
email) that are available, and standard TCP/IP diagnostic commands.
Finally, we’ll finish up with a discussion of new developments
in TCP/IP, as it evolves to better serve its growing community of users.
In this chapter, you also learned
about the architecture of the TCP/IP protocol suite, some common user-level
features it offers and where TCP/IP is going in the future.
- Know that TCP/IP services are found at specific
ports, and are contacted by client programs, which communicate using
the appropriate protocol
- Common TCP/IP application protocols and their
port numbers
- Name services, and the approaches to them by
various vendors
- When to use various TCP/IP troubleshooting utilities
- IPv4 vs. IPv6
