Ch 5: Network Systems Technology

About This Chapter

Watch computer application video lessons and complete the quick quizzes to check your progress. Take this opportunity to learn about the components of telecommunications systems, computer networks and more.

Everywhere you look these days people are using things like cell phones and wireless internet. This is even true for businesses. No matter why you use telecommunications systems, it's always good to understand how they work, what the different elements are and what it takes to have a properly working system. In these lessons, you will learn the information you need to know about different types of telecommunications systems that are used today.

You might want to start with our lesson that explains the components of network and telecommunications systems. Study our lesson on client server and mainframe systems to continue your studies.

If you are looking for a bit more information, take a look at the lesson on networking hardware. You can become familiar with the different types of hardware, such as routers, modems, switches, bridges and gateways. Move on to the network operating systems lesson to learn about different types of operating software. When you need to know more about computer networks and the distributing processing, then we have a lesson that will introduce you to terms like PAN, LAN, WAN and MAN. If it is connecting a network that you want to study, then watch our lesson that covers Star, Bus and Ring Network architectures.

Perhaps you want to study wireless communications. If that's the case, then take a look at our lesson on communication and wireless computing devices. This lesson will tell you all about these terms: GPS, PDA, cellular and satellite. You might also want to take a look at the wireless communication lessons that cover short-range, medium-range and wide-area options. In these lessons, you will discover more about terms that include Bluetooth, ZigBee, infrared transmissions, wi-fi, hotspots, microwave, 3G, 4G and wiMax.

Thanks for watching and happy learning!
