create a journal Assignment that will prepare you to conduct the organizational profile needed for your final project. In this lab, you will also 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 of this lab is to leverage the operating system on the computer you are using for this course to report on its architecture.

Execute one of the commands below in the command shell or use the System information app, that comes with your operating system. For example, if you are using Windows, you will run the systeminfo command. Note that the system information app is likely to have more complete information than the systeminfo command in the command shell. Here are the optional commands:

Windows: Execute the command systeminfo

Linux: Execute the command cat $/$proc$/$cpuinfo

Max OS X: Execute the command system$\_$profiler SPHardwareDataType

Review the output from a command above and, in your journal, describe the type of CPU $($Intel or AMD$),$ and is it an i$5,$ i$7,$ or i$9,$ or K$8,$ or K$10?$ In addition, how much RAM is on the computer, and any particular information you find interesting. 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, explain at least one system call from the course textbook that the operating system executed in order to create the output you reviewed. put detailed explanation

Hint: Each of the commands above creates a new process, so Windows will leverage a WIN$32$ system call from Section $1\mathrm{.}6\mathrm{.}5$ and Linux$/$OS X will execute a variant of one of the system calls listed in Figure $1-18.$
