Students will review:
This chapter helps students review the concepts in a Network Systems Technology unit of a standard college information systems course. Topics covered include:
- Components of a telecommunications system
- Client/server and mainframe
- Computer networks and distributed processing
- Short-, medium- and wide-range wireless
- How star, bus, ring and mesh arrangements connect organizations' computers
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. 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.
3. Telecommunications Hardware: Routers, Modems, Switches, Bridges, and Gateways
Building a computer network requires specialized hardware. Learn about transmission media and the variety of hardware devices needed for a computer network.
4. Network Operating Systems (NOS): Windows & Novell Net Ware
Every computer needs an operating system, and networks require their own operating systems. Learn about the specialized functions of network operating systems.
5. Computer Networks and Distributed Processing: PAN, LAN, WAN, MAN
Computer networks can vary in size from a handful of devices within a single room to millions of devices spread across the entire globe. Learn about the different types of networks.
6. 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.
7. Short-Range Wireless Communication: Bluetooth, ZigBee & Infrared Transmission
Short-range wireless communication uses signals that travel from a few centimeters to several meters. Learn about some of the most widely used types of short-range wireless technologies.
8. Medium-Range Wireless Communication: Wi-Fi & Hotspots
WiFi is the most widely used medium-range wireless communication technology. Learn how WiFi standards and access points are used to create hotspots for Internet access.
9. Wide-Area Wireless Communication: Microwave, Satellite, 3G, 4G & WiMAX
Wide-area wireless communication travels large distances, from several kilometers to thousands of kilometers. Learn how much of the world's communication uses microwaves in cellular networks, WiMAX and satellite communications.
10. 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.
11. What Is a Virtual Private Network (VPN)? - Definition & Types
A virtual private network (VPN) provides a way to use network resources securely in a remote manner. In this lesson, we'll cover why we use VPNs, what types of VPNs are used, and what is necessary in order for VPNs to work.
12. Bandwidth vs. Throughput
This lesson is about two similar concepts - bandwidth and throughput. These two concepts will be described and compared to get an idea of how these apply to things like speed on a home network.
13. Throughput vs. Latency
The actual speed of data on a network can be described by words like 'throughput' and 'latency.' In this lesson, we will define both of these words, and see how they help fulfill the demand for data on a network.
14. What is the .NET Framework?
Software development is an important topic these days. In this lesson, we'll take a look at the .NET framework, what it is, some of its features, and the environments where it can be used.
15. What is ActiveX?
The Internet has provided a wealth of opportunities, both from a business and personal perspective. In this lesson, we'll take a look at ActiveX, what it is, what it's used for, and some of its strengths and weaknesses.
