What is a Network Protocol? - Types & List

1. What is a Network Protocol? - Types & List

Network protocols. You use them every day. Some even every minute, yet most people wouldn't know it. Network protocols are simply the rules the internet lives by. In this lesson, we'll learn what network protocols and look at the different types.

What is an Internet Service Provider (ISP)? - Definition & Examples

2. 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.

What is Optical Fiber? - Definition & Concept

3. 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.

Data Link Layer of the OSI Model: Protocol, Functions & Design

4. Data Link Layer of the OSI Model: Protocol, Functions & Design

We all want our information to get where it is supposed to go quickly and without any problems. In network communication, this starts in the second layer, the data link layer.

Network Layer of the OSI Model: Functions, Design & Security

5. Network Layer of the OSI Model: Functions, Design & Security

In this lesson, we introduce you to the network layer of the OSI model. The network layer is the stage concerned with host to host communication tasks, like protocols, switching, routing, and addressing.

Presentation Layer of the OSI Model: Definition, Functions & Protocols

6. Presentation Layer of the OSI Model: Definition, Functions & Protocols

In this lesson, we will explore the Open Systems Interconnect (OSI) model and take an in-depth look at the presentation layer. We'll also use an illustration to see how presentation layer data flow occurs within the seven functional layers of the OSI model.

Session Layer of the OSI Model: Functions, Protocols & Examples

7. Session Layer of the OSI Model: Functions, Protocols & Examples

In this lesson, we will discuss the session layer, layer 5 of the OSI model. We will talk about how the session layer sets up, manages, and maintains multiple network communicative sessions, and you'll learn about APIs like NetBIOS and TCP/IP.

Transport Layer of the OSI Model: Functions, Security & Protocol

8. Transport Layer of the OSI Model: Functions, Security & Protocol

In this lesson, we'll explore the seven layers comprising the OSI model with a focus on the transport layer. During our discussion, we'll define the transport layer, examine its functions and go over the supporting network protocols.

Internet Connectivity and Communication Standards

9. Internet Connectivity and Communication Standards

This lesson explores the network protocols that aid in data communication. It also discusses networking standards (formal and de facto) and introduces some of the organizations that are involved in establishing these networking standards.

The Internet: IP Addresses, URLs, ISPs, DNS & ARPANET

10. 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.

What is Hostname Resolution?

11. What is Hostname Resolution?

Hostname resolution makes it easy to locate a system on a large network. In this lesson, we will see what Hostname Resolution is all about and how a System Administrator would make use of it.

What is Communication Protocol? - TCP/IP & Explanation

12. What is Communication Protocol? - TCP/IP & Explanation

In this lesson, you will learn about 'The Internet's Protocol Suite', composed of the Transmission Control Protocol (TCP), and the Internet Protocol (IP); abbreviated as TCP/IP. Lesson highlights include: TCP and IP defined, how TCP/IP became the foundation for today's Internet communications and how the five layers of the TCP/IP model compares with the seven layers of the Open System Interconnection (OSI) model.
