Project 1.1 Understanding Key Concepts Overview

It is important to understand the basic networking standards, including the OSI, DoD, and Internet networking models. These models provide common terms for describing network operations and ways of describing and comparing network components.This project reviews common networking terms and terms relating to networking standards.

Outcomes After completing this project, you will know how to:

 identify key terms and concepts related to networking basics  identify key terms and concepts related to network components and network types

What you’ll need To complete this project, you will need:

 the worksheet below Completion time 20 minutes Precautions None

The worksheet includes a list of terms related to networking standards and components, with models given on the left and descriptions on the right. Match each term with the description that it most closely matches. You will not use all descriptions. Each description can be used only once.G Router A. Process of having two computers recognize each other and open a communication channel

E Hub B. Block of data formatted for transmission over a network

N Cable plant C. Transmission media and network devices making up the physical structure of a network

K Peer-to-peer D. Specialized computer providing resources to a network

M Wide area network E. Connection device used to connect network cables at a central connection point

P Client/server F. Device that enables a computer to physically connect to a network

A Connection G. Network communication device used to connect two or more networks (subnetworks or network segments)

Networking Fundamentals 3

C Infrastructure H. Low-level protocol that is currently the protocol most commonly used

F Network adapter I. Rules and standards defining network communications

L Node J. Networking model based on all network entities being tracked and managed through a directory that provides centralized management and control.

B Packet K. Networking model with no centralized security or management control

I Protocol L. Any uniquely identified network device

H Ethernet M. Traditionally defined by LANs connected through the switched telephone network over a large geographic area

D Server N. Path over which network devices communicate in a wired network infrastructure

• Means by which computers identify each

other on a network

• Networking model that has centralized

security control as a defining feature

Project 1.2 Identifying Basic Components Overview

An important part of understanding network fundamentals is the ability to recognize common network components. Many connectivity components are common to the majority of PC networks.

Outcomes After completing this project, you will know how to:

 recognize common network components  recognize wired and wireless networks
