About This Chapter
Telecommunications Systems - Chapter Summary
If you're looking for an overview of telecommunications systems, check out this comprehensive online chapter. Through a series of engaging and short video lessons, you'll examine the basic components of telecommunications systems, network architecture, communication devices and computer networks connections. To help you reinforce your understanding of these topics, we've included interactive lesson quizzes and a chapter exam. You can work through the chapter at your own pace, and when you're finished, you should be equipped to:
- Identify components of telecommunications systems
- Compare types of networks, including LAN, WAN, VPN and EPN
- Differentiate between tiered and peer-to-peer network architecture
- Explain how computer networks are connected by star, bus, ring and mesh topology
- Evaluate the functions of several communication and wireless computing devices
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.
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.
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.
4. 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.
5. 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.
