This new course from TeachWOT gives a comprehensive overview of how computer networks are constructed, and how they work together. The course outlines the 7 different layers that comprise the network core, called the Open System Interconnection (OSI) Layers. Course participants will gain a detailed understanding of the various forms of interconnectivity, communication and protocols for each. There is also a review of an alternative framework in the TCP/IP Model, which outlines four network layers. The course provides a detailed view of Layers 2, 3, 4 and 7 – the Data Link, Network, Transport and Application Layers.
Network professionals, engineers and technical managers can benefit from this course, which will equip them with detailed knowledge and the latest information to assist with the planning, management and maintenance of data networks.
10 modules, self-paced learning, to be completed within a 3 month period.
Course participants will gain a detailed knowledge of the OSI layers, ranging from the lowest stack of the network – where the bits are transmitted across a medium, up to the highest stack – where application resources are sent and received over the internet.
Particular attention is given to IPv4 addressing, subnetting, TCP, HTTP, and modern cryptographic methods such as encryption, hashing & digital signatures.
The course provides a deep understanding of the fundamentals of computer networking and outlines a framework to allow participants to comprehend the function of each of the network layers. Upon, completion, participants should be able to:
> Understand the fundamental aspects of networking and modern cryptography
> Define computer networking
> Distinguish between the OSI model and the TCP/IP model
> Analyze the different layers in network communications and how they interact
> Identify features and functions of different networking protocols
> Explain the purpose of different address types defined at each layer of the OSI reference model; Demonstrate IP addressing and Subnetting
> Describe the purpose and use cases of modern cryptographic methods such as Encryption, Hashing, and Digital Signatures.
