5. Click on the Ethernet chart and display the following:

Link speed. (2 marks)

Network Connection. (2 marks)

IPv4 address in use. (2 marks)

Capture and save screenshots to show how you have performed the above task.

Upload “Task Manager” document.

(Total: 20 marks)

22. Create a word processing document named “Memory Usage” and use it to save your answers to questions 1 to 5
below:

With the help of task manager, perform the following:

23. Create a word processing document named “Virtual memory” and use it to save answers to questions 1 to 4 below:
Virtual memory is a common technique used in Network operating systems. It is used on both hardware and
software to enable a computer compensate for physical memory shortages, temporarily transferring data from
random access memory (RAM) to disk storage.

Required:

1. List current size of the virtual memory (paging file) used by your network operating system. (4 marks)

2. Display the Drive [Volume Label] that contains the paging file. (6 marks)

3. Capture a screenshot to illustrate the way you can use Disk Management to create a second partition with at least 2GB. (6 marks)
