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.
9. 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.
10. e-commerce & m-commerce: Buying & Selling on the Web & Mobile Devices
E-commerce and m-commerce have transformed the way that organizations and consumers conduct business. Additional topics discussed in this lesson include B2B, B2C, C2C, and e-government.
11. 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.
12. Network Layer of the OSI Model: Functions, Design & Security
In this lesson, we'll introduce 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.
13. 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.
14. 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.
15. 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.
