Hello I need help with my computer class. I am not sure which commands to use to create this directory with powershell

Any help would be greatly appreciated!

Note: As the IT administrator for the Acme Technical Institute, a computer training school that offers the following courses in three different departments: Networking, Security, and Programming, you are tasked with using PowerShell to create a folder structure to store the files for the courses offered in each of three departments. The folder structure should mirror the following class structure. Networking NET303: Network Design and Management NET404: Network Forensics Security SEC303: Advanced Cryptography SEC404: Security Policies and Procedures Programming PRO303: Information Structures with Java PRO404: Information Structures with Python Each course should have a folder to hold lecture notes, faculty notes, and assignments. Faculty members should have full control to read and write all folders and students should have read-only access to the Lecture Notes and Assignments folders to enable them to find the materials specifically designed for them. 8. At the PowerShell prompt, execute the command to return to the C:lyourname directory. 9. At the PowerShell prompt, execute tree to list the entire folder structure layout you just created
