Unit 5 Lab Assignment 5: Networking and Security (40 points)

In this assignment, you will learn to check network configurations and services and to configure an IP address on a computer.
For each of the two questions, do the following:

1. Create a document (use Microsoft word or any equivalent tool such as LibreOffice) and name it appropriately to reflect the assignment type, number, and your name. 

2.
Answer the following questions (if any) in the document you created
and justify your answers. To do this, you may need to perform some tasks on your computer, use a snipping or “print screen” tool to take screenshots, and paste the illustrations/pictures into the document.
Showing screenshots only does not constitute answering a question. You need to provide both the answer to the question and the screenshots.

3. Save and upload the document to the learning management system (Blackboard).
