In conclusion, knowing the information on OS one is using is
important to have, especially during the troubleshooting. It also
helps to know what product or processor you are using,
especially for someone like me, so that when you go in market
to get better product you can compare and contrast or add-on

IT 600 Module Two Journal Guidelines and Rubric
Overview: There are five journal assignments in this course,
many of which have a hands-on element to them in that they
will ask you to perform functions or
commands on your computer. After completing the hands-on
requirements, you will write a journal entry in which you will
answer questions related to what
you did.
This assignment will prepare you to conduct the organizational
profile needed for your final project. You will apply the
operating system concepts you read
about in the course textbook to the real world. Windows, Linux,
and OS X provide command line utilities that display system
architecture information as well as
how the operating system is configured to interface with
hardware.
The goal is to leverage the operating system on the computer
you are using for this course to report on its architecture. You
will use knowledge gained from
running the commands to complete the technical description
portion of the final project.
Prompt: For this assignment, you will need to:
1) Execute one of the commands below in the command shell
that comes with your operating system. For example, if you are
using Windows, you will run

5. the systeminfo command. Here are the optional commands:
SPHardwareDataType
2) Review the output from a command above and write a journal
entry that describes the following critical elements:
For example, Windows displays the installation date and when
the system was last booted. Linux displays the number of
bogomips (unreliable CPU performance
metric) for each processor or core. Of particularly interest from
a historical perspective, Mac OS X will likely display an Intel
processor running on Apple
hardware. In your journal entry, explain at least one system call
from the course textbook that the operating system executed in
order to create the output you
reviewed.
Hint: Each of the commands above creates a new process, so
Windows will leverage a WIN32 system call from Section 1.6.5

6. and Linux/OS X will execute a
variant of one of the system calls listed in Figure 1-18.
Guidelines for Submission: Your work must be submitted as a
journal entry.
Instructor Feedback: This activity uses an integrated rubric in
Blackboard. Students can view instructor feedback in the Grade
Center. For more information,
