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. 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.
4. What Is a Client-Server Network? - Definition, Advantages & Disadvantages
A client-server network is a central computer, also known as a server, which hosts data and other forms of resources. Clients such as laptops and desktop computers contact the server and request to use data or share its other resources with it.
5. 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.
6. 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.
7. What is an Internet Service Provider (ISP)? - Definition & Examples
An Internet Service Provider (ISP) is a company that provides Internet access by using copper, fiber, or even satellite communications to the customer. In this lesson, we will cover exactly what an ISP is, how the ISP connects customers, and what type of services the ISPs provide.
8. The Internet: IP Addresses, URLs, ISPs, DNS & ARPANET
We'll cover the basics of the Internet, including its history and functioning. Key topics include IP addresses, TCP/IP communication protocol, DNS, URLs, and the transfer of information as packets through the Internet.
9. Future Trends in Networking
Discover what is new in networking and what we might see in the future. No so far back in the past, everyone used a dial up on a modem to connect to the Internet. Now, we have mobility! We are no longer tied to wires and fixed modems!
