Organizations that Create Networking Standards

1. Organizations that Create Networking Standards

In this lesson we will understand what networking standards are and the significance they play in technology and the Internet. A brief overview of the various organizations at the heart of some of these networking standards will be presented.

Internet Packet: Definition & Explanation

2. Internet Packet: Definition & Explanation

In this lesson, we'll define Internet packets and describe Internet packet construction. We'll also discuss the 14 fields comprising a typical data packet and how you can test for and correct packet loss problems, such as signal loss.

OSI Model: Using Open Systems Interconnection to Send and Receive Data

3. OSI Model: Using Open Systems Interconnection to Send and Receive Data

The Open System Interconnection (OSI) model describes how data is sent and received over a network. It consists of seven layers: the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. This lesson discusses how the OSI model works and the role of each layer for transmitting messages.

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

4. Application Layer of the OSI Model: Definition, Functions & Protocols

Learn about how the Application Layer of the OSI model allows us to perform basic daily activities. Go over the definition of the Application Layer as well as its various functions and protocols.

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

5. 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

6. 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

7. 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.

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

8. 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.

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

9. 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.

Physical Layer of the OSI Model: Definition, Components & Media

10. Physical Layer of the OSI Model: Definition, Components & Media

This lesson discusses the 7th or physical layer of the OSI model. It also discusses the various components and media used in this layer for the transfer of data. Wired data transmission in the physical layer and its associated components will be broadly covered.

Internet Connectivity and Communication Standards

11. 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.
