1. What is a Computer Network? - Types & Definition
A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server. The Internet itself can be considered a computer network.
2. Importance of Communication Networks
In this lesson, we will learn how important communication is and relied on in our society today. We will examine different instances in our daily lives that involves communication networks.
3. 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.
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.
5. 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.
6. Cables for Networking: Types & Characteristics
Have you ever wondered how network connections work? This lesson will take you through the variety of network cable types, their uses, and their ideal use situations.
7. 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.
8. Network Interface Card (NIC): Types, Function & Definition
To connect to a network, a computer uses a network interface card (NIC). A NIC controls the wired and wireless connections of a computer to exchange information with other computers and the Internet.
9. LAN Card: Definition, Function & Types
In this lesson, you'll be learning about LAN (or Local Area Network) cards, which is used to connect computers to networks. After the lesson, test your knowledge with a quiz.
