Chapter 1 Summary

-This chapter introduces the basic concepts of computer networking. It presents the technologies and techniques for assembling a computer network using the Ethernet protocol. You should now understand the following major topics:

  • The various LAN topologies
  • The concept of CSMA/CD in the Ethernet protocol
  • The structure of the Ethernet frame
  • The purpose of a network interface card
  • The purpose of a MAC address
  • How to determine the MAC address for a computer
  • The purpose and structure of an IP address
  • The concept of private IP addresses
  • The OSI model
  • The network topologies and technologies used to implement twisted-pair computer networks
  • How to configure and verify a computer’s IP address
  • How to configure a home network and an office LAN
  • The purpose of the link light
  • The purpose of using ping to test a network connection

Reading Questions

What is the most common network topology? -Star

A protocol defines the network architecture used to interconnect the networking equipment

  • False

In an Ethernet LAN, who assigns the MAC Address to an Ethernet interface?

  • Hardware manufacture

The MAC address on a Windows computer can be accessed by typing ipconfig /all from the command prompt.

  • True

True/False: A network protocol is a set of rules established for users to exchange information.

  • True

Which of the following is a valid IPv4 address?

  • An IP address is a set of numbers that identify your computer on a network. IPV4, the traditional numbering scheme, uses four integers ranging from zero to 255 and is set apart by periods. For example, "204.120. 0.15" is a valid IPV4 address.

The OSI Model intends to provide a framework for networking that ensures compatibility in the network hardware and software.

Mnemonic to help remember the 7 layers of the OSI Model and record it here: People don't need those stupid packets anyway

In computer networking, MAC stands for media access control.

A MAC address is 6 bytes, or 12hex characters, in length.

The first 6 digits of a MAC address are called the organizationally unique identifier (OUI) and are used to indicate the network interface vendor.
