Learning about the Roles and Interrelationship of TCP, IP, and Ethernet
The First Step in Understanding Networks
- These days we use TCP, IP, and Ethernet on a routine basis. They
are indispensable for network communication. In order to understand
the mechanism of network communication, it is important to learn how
each of the three technologies works and how they work together. This
article examines the roles of the three technologies inside a PC to
help you enhance your understanding of the mechanism of a network as
a whole.
Part 1 Introduction: If you learn about the processing carried
out in a PC, you can understand the mechanism of an entire network
Part 2 Roles and Interrelationship: The three main technologies
perform their own tasks while working together
Step 1: Partitioning data into clusters of proper size
Step 2: Determining the route to the party you are communicating with
Step 3: Searching for a destination MAC address in a LAN
Step 4: Sending data to a transmission channel
Step 5: Taking received data to an application
Part 3 Summary: Determining the flow in a network as a whole
with a five-step approach

What Kinds of Roles Are ISPs Playing?
Providing a link between users and the Internet
- Although Internet users are familiar with the existence of Internet
service providers (ISPs), they are invisible, as if they exist in a
different world. This article looks at what ISPs actually do.
Briefing: Let’s gain a comprehensive understanding of ISPs
by learning about their roles
Backbone: The network backbone of ISPs is huge routers, and their
reliability is ensured by maintaining a high level of redundancy
Service: Various types of servers play key roles behind the scenes
by dealing with a huge amount of data
Boxed Article: Access line networks have become independent from
ISPs’ networks due to the advent of ADSL, etc.
