The network layer is responsible for the delivery of packets from any source to any destination through intermediate routers. Each application relies on the transport layer that is described in this unit. Completing this unit should take you approximately 31 hours.
Completing this unit should take you approximately 4 hours. This unit will introduce the basic concept of a computer network and arm you with the tools you will need to work through the more technical aspects of this course.
Multimedia, Security, and Cloud Computation over the Internet Multimedia over the Internet becomes more and more popular. Completing this unit should take you approximately 13 hours.
You will also be introduced to one of the most recent Internet-based technologies: This unit guides you through the principles of the link layer.
Protocols In life, protocols define the way we interact with other people - for example, the way we behave in a public place. This unit guides you through the protocols for transmitting multimedia content, such as voice and video, over the Internet, and discusses security, reliability, and fault tolerance issues related to Internet applications.
Completing this unit should take you approximately 17 hours. These protocols are the fundamental protocols for modern multimedia applications over the Internet. In computer science, protocols are formal sets of rules that dictate the ways in which computers communicate with one another over a network medium.
You will take a look at the different types of networks that exist, with the primary focus on the LAN. We will learn that networks can run out of space, meaning that unique addresses for different machines are no longer available.
The concepts presented in this course will provide you with the background information needed to develop network applications, take a network certification course, or communicate with other networks neighboring your LAN.
This unit will explain how you can address machines on a network from that layer, use IP addresses to determine physical addresses, and identify the different mechanisms in the link layer that can correct packet collisions when data is transferred over the wire.
The chapter ends with a detailed discussion of the two types of computer networks that are important today from a deployment perspective: Completing this unit should take you approximately 6 hours. Computer networks make it possible for one device to communicate with another device.
First, we will develop a simple reliable transport layer protocol.
Completing this unit should take you approximately 18 hours. Finally, we will discuss socket programming and how it can be used to develop network applications. Another example of a computer network is the local area network, or LAN.
Networking Fundamentals When you think of networking, what is the first word that comes to mind? Completing this unit should take you approximately 20 hours.
Then the textbook will direct your focus to computer networks with a discussion of how multiple hosts share one transmission medium.
If you can access all of the desktops, laptops, wireless devices, and printers in your workplace, college, or home, you have a LAN. The Internet is an example of a massive computer network. The unit continues with an introduction to the concept of layers, which is central to understanding how computer networks operate.
Protocols constitute the backbone of networking. The Network Layer In this unit, we will learn how packets groupings of data travel on a network and how each machine can be addressed uniquely so that data transport between two nodes is reliable.
The application layer is where all network processes and applications run. You will also become familiar with Request for Comments RFC documents, which are standards that define all of the Internet protocols.
