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. ARPANET: Definition & History
ARPANET was the first proven concept of sending and receiving information regardless of geographical location in near real time. Developed under U.S. Advanced Research Projects Agency, a Department of Defense agency, ARPANET uses packet-switch technology in order to send and receive data with built-in error correction and package assembly. ARPANET was the first design of what has become known as the Internet today.
12. NSFNET: Definition & History
In this lesson, you will become familiar with the National Science Foundation's network and its impact on worldwide communications. Included is a brief history of the NSFNET and how its advancements in network technology contributed to shaping the Internet.
13. Time Multiplexing: Applications, Advantages & Examples
Communication is important, particularly today, as we strive to increase our capabilities. In this lesson, we'll take a look at time multiplexing with applications, examples, and advantages.
14. Trusted Network: Solutions, Environment & Technologies
A network is a connection of computers, servers and electronic devices that enables the devices to communicate with each other. A trusted network requires authentication through login credentials and encryption of data. Today we will learn more about trusted networks.
15. What is Optical Fiber? - Definition & Concept
Optical fiber is a type of cabling technology that uses light to carry voice and data communications (telecommunications) over distances both great and small. This lesson will provide a definition of optical fiber, explore the different types and explain how the different types are used. We'll also look at the advantages of optical fiber over traditional copper wiring and examine the limitations.
16. NTSC vs. PAL: Difference & Explanation
In this lesson, we'll describe the differences between NTSC and PAL. We'll also explain some of the concepts beneath these two similar ways to deliver a video signal from one place to another in various parts of the world.
17. What is LTE? - Definition, Speed & Network
LTE stands for 'Long-Term Evolution' and is currently the fastest available type of wireless network. In this lesson, we will learn more about how LTE works and how it is keeping up with wireless demands.
