WHAT'S GOING ON IN THERE?

THE MICROPROCESSOR CLOCK IS TICKING. Data bits are flying in and out of RAM and zooming over the data bus to a storage device. All that seems invisible, but wait! You can get an idea of what's going on inside the system unit. Who needs to know? You might. If you suspect your computer has a virus. If you think your computer might have been compromised by a botnet. If your computer seems sluggish. Windows and OS X include monitoring utilities that provide all kinds of information about your computer's status.

For this lab, you'll need a desktop or laptop computer running either Windows or OS X. The instructions are generalized; they provide helpful guidelines, but not specific steps. You may have to explore a bit to find all the tools needed to complete the assignment, but that is all part of the learning experience.

ASSIGNMENT:

Create a Google Doc and name it "Computer Exploration". For each step below, take a screenshot of your activity and paste it into the Google Doc. Write a summary statement or paragraph of what you did and its results under the screenshot

Here are written instructions for how to take a screenshot: http://www.take-a-screenshot.org/

Save your Google Doc as a PDF and upload it using the "Add Submission" button at the bottom of the assignment.

1. Open your computer's monitoring utility.Take screen shot

On a Mac, select the Applications folder from the dock. Select the Utilities folder, then select Activity Monitor.

On a PC with Windows, make sure you are at the Home screen Use the Search box to find and launch Task Manager.

2. Examine your computer's CPU usage.Take screen shot

On a Mac, select the CPU tab; on Windows, select the Performance tab.

CPU utilization is expressed as a percentage of total processing capability. If CPU utilization exceeds 10% when you are not using software, it might signal a security breach. Temporary spikes are normal; and when you are playing 3-D games or using compute-intensive software, the usage could remain above 70%.

What is the current CPU utilization on your device?

3. Check processes.Take screen shot

On a Mac, processes are listed on the CPU tab; on Windows, select the Processes tab.

A process corresponds to a program. Any programs that are currently running put a load on the CPU.

What is the process with the highest CPU usage? Do you recognize the program associated with this process? If not, look it up online.

4. Check for malware.take screen shot

Some processes are launched by the operating system rather than application software. If you don't recognize a process, you can find out if it is legitimate by checking online.

Select a process with an unusual name and search for it online. What is its name and what does it do?

5. Check memory.take screen shot

On a Mac, select the Memory tab; on Windows, remain on the Processes tab.

As you know, RAM holds the operating system, programs, and data, but the amount of stuff that's actually in RAM is pretty surprising.

Find the listing for Kernel-task (Mac) or System (Windows). That process is part of the operating system. How much memory is it using?

What is the name of the software application that uses the most memory?

6. Check storage.take screen shot

On a Mac, choose the Disk tab; on Windows, remain on the Processes tab.

Programs send data to storage even when you are not in the process of manually saving files. Some programs create autorecovery files as temporary backups, and Web pages write cookies.

Find a process that is writing data to disk even when you are not actively using it. What is the name of that process and what is its purpose?

7. Save your Google Doc as a PDF and submit
