Lesson 1

Introduction to Designing TCP/IP Solution

Organizations are facing a growing need for Internet connectivity, and connectivity between dissimilar operating systems and hardware platforms spread over large geographic distances. Because TCP/IP operates on a wide variety of physical networks and can be scaled to suit small to large networks, it is the only protocol that can meet the requirements of these organizations.
Unlike many of the LAN protocols formerly in widespread use, such as NetBEUI and IPX/SPX, TCP/IP is a relatively complex networking protocol to set up and configure. You must plan carefully how to set up client machines and how your TCP/IP network infrastructure will be implemented. If the network is not designed with the advantages and limitations of the TCP/IP protocol in mind, network performance will be dismal and unreliable.

By the end of this module, you will be able to:
  1. Define the components of TCP/IP protocol suite
  2. Define decisions that influence the design of a TCP/IP solution
  3. Define the features of TCP/IP and their functionality
  4. Define the elements utilized in TCP/IP design
  5. Define the IP addressing schemes available in private networks
  6. Determine the number of hosts per subnet and number of subnets
  7. Define configuration methodologies used by network hosts
The next lesson defines the importance of TCP/IP in a network, and introduces you to protocol suite.

(TCP/IP) Transport Control Protocol/Internet Protocol is a protocol system, a collection of protocols that supports network communications. The answer to the question
What is a protocol?
must begin with the question
What is a network?
This module describes what a network is and shows why networks need protocols. You also learn what TCP/IP is, what it does, and where it began.
