Description

Write a journal entry 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 that comes with your operating system. For example, if you are using Windows, you will run the systeminfo command. Here are the optional commands:


Prompt: For this assignment, you will need to:

  1. 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 the systeminfo command. 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
  2. 2) Review the output from a command above and write a journal entry that describes the following critical elements:
    •  the name and description of the processor
    •  the number of cores
    •  the amount of memory
    •  any particular information you find important and why............. 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.

      Hint: Each of the commands above creates a new process, so Windows will leverage a WIN32 system call from Section 1.6.5 and Linux/OS X will execute a variant of one of the system calls listed in Figure 1-18.

Introduction
The operating system is entirely responsible for the coordination and management of
activities such as, allocation and control of memory, regulation of input and output, management
of files and facilitation of networking. Operating systems, windows, Linux and OS X, provide
command line utilities which typically display the system’s architecture information and how the
OS is configured to interface with hardware (Stevens, 2010). This can be fulfilled by the use shell
commands programs which execute the operating system commands. The shell, is thus, a part of
the command processor that accepts commands (Gutierrez, 2007). The most prevalent shell
commands that can be executed to display the system’s architecture in windows are, WMIC CPU
GET /Format: List and systeminfo command. This journal presents a review output of the
Windows’s systeminfo shell command.
Processor
A processor or Central Processing Unit (CPU), which is the logic circuitry, processes the
basic instructions and responds to the basic instructions that drive the operations of the computer
(Peng, 2007). It mainly engages in fetching, decoding, execution and writeback. All devices, for
example desktops, smartphones, tablets and even Television set use a CPU. The logical processor
installed and executed from the system info command is intel ®, formally described as Intel64
Family 6 Model 55 Stepping 8. These processor provides generic versions of drivers which execute
a significant number of purposes.

Cores
Cores are part of a processor which mainly receive instructions, perform calculations and
formulate results. Typically, core(s) are essential for the prompt functioning of the Central
processing unit (Peng, 2007). Most processors today contain two or more processors mainly for
enhanced performance, efficient simultaneous processing of tasks and reduced power
consumption....
