This course is divided into three sections. The first section will introduce the different architectural structures and devices used to build networks and facilitate communication. You will be introduced to the Client-Server model, IP addresses, Binary and the Domain Name System.
The second section will discuss ports and protocols and introduce an important conceptual model known as the OSI model. You will learn the theory behind each layer of the OSI model and then be introduced to an industry wide application used to analyse network activity called Wireshark.
The final section will apply this theory to practice by using command line utilities that operate on the different layers of the OSI model.

Course material is only available to enrolled students.
Virtual Lab System Requirements
Although it is not a requirement to complete this course, applying the theory component of the course in our virtual labs is strongly encouraged. Most modern PC’s and Apple computers (purchased within the last 5 years) should meet the system specifications required to run the lab environment.
WARNING: Apple's M1 chips do not currently support virtualization technology and are not suitable for our lab environment.
To participate in the virtual lab environment please ensure your computer meets our minimum system specifications:
Tablets, Mobile devices, and Netbooks are not suitable.
Operating System: Windows 10 or MacOS Sierra (or above).
Processor: Minimum AMD Ryzen 5 or Intel i5 processor or newer required.
Memory: Minimum 8GB of RAM required – 16GB RAM preferable with a 64bit dual core processor.
Storage: Minimum 50GB free disk space.
Note: Your computer must be compatible with virtualization technology.
To check if your PC has virtualization capability refer to this article HERE

Linux computers will not be able to support our Virtual Lab environment.
Apply M1 computers do not currently support virtualization technology and are not suitable.
Any computers known to have overheating issues are not permitted.
If your device does not meet our local device system requirements – please purchase our browser-based challenge labs for an alternative hands on training experience.
