Ch 7: Networks Access and Architecture

About This Chapter

Watch video lessons to learn about the methods, components, and structures of telecommunication networks. Use the quizzes that follow each lesson to measure your learning.

Networks Access and Architecture - Chapter Summary and Learning Objectives

Have you ever wondered how messages and information are sent from one device to another? As signals are transmitted, the telecommunications network is responsible for routing the information to the correct place. This chapter introduces the five components that allow such transactions to occur and explains multiple types of networks that are used. This chapter can help you understand the following:

  • How telecommunications systems work
  • Network systems
  • Network designs
  • Communication between systems
  • Telecommunication devices

Video Objective
The Components of a Telecommunications System Learn about the elements of network and telecommunications systems.
Types of Networks: LAN, WAN, WLAN, MAN, SAN, PAN, EPN & VPN Recognize various types of networks and understand their functions.
Network Architecture: Tiered & Peer-to-Peer Look at two types of designs for a communications network.
Network Layouts: Bus, Star, Ring, Mesh & Fully Connected Learn about some common layouts in network topology.
What is Distributed Computing? - Principles, Environments & Applications Explore how networked systems communicate.
Client/Server and Mainframe Systems Used in Telecommunication Systems Understand roles and relationships within network communication.

7 Lessons in Chapter 7: Networks Access and Architecture
The Components of a Telecommunications System

1. The Components of a Telecommunications System

Telecommunication is communication at a distance using electrical signals or electromagnetic waves. Learn about the components and properties of telecommunication systems.

Types of Networks: LAN, WAN, WLAN, MAN, SAN, PAN, EPN & VPN

2. Types of Networks: LAN, WAN, WLAN, MAN, SAN, PAN, EPN & VPN

There are so many different types of computer networks in existence, it can be hard to understand the differences between them, particularly the ones with very similar-sounding names. This lesson explains the structures and functions of some of the most popular computer networks.

Network Architecture: Tiered & Peer-to-Peer

3. Network Architecture: Tiered & Peer-to-Peer

Network architecture describes the allocation of tasks between computers in a network. Learn about the most common types of network architecture - peer-to-peer and client/server - in this video lesson.

Client/Server and Mainframe Systems Used in Telecommunication Systems

4. Client/Server and Mainframe Systems Used in Telecommunication Systems

Telecommunications are managed in a number of different ways, including peer-to-peer, client/server and mainframe systems. Learn why client/server has become the most widely used network architecture.

How Star, Bus, Ring & Mesh Topology Connect Computer Networks in Organizations

5. How Star, Bus, Ring & Mesh Topology Connect Computer Networks in Organizations

Computers in a network are connected in some logical manner, referred to as network topology or network architecture. Learn about the different types of network architecture.

What is Distributed Computing? - Principles, Environments & Applications

6. What is Distributed Computing? - Principles, Environments & Applications

Some computing tasks require the power of multiple computers. Learn how distributed computing coordinates tasks performed on multiple computers at the same time.

Communication & Wireless Computing Devices: GPS, PDA, Cellular & Satellite

7. Communication & Wireless Computing Devices: GPS, PDA, Cellular & Satellite

A large number of different devices use wireless communications networks. Learn about the different types of devices and which communication signals they use.
