1. IT 600 Final Project Guidelines and Rubric
Overview
IT professionals are often called upon to make decisions,
provide recommendations, and perform analyses that require an
in -depth understanding
of the inner workings of an operating system. This summative
assessment will provide students with the knowledge and skills
required to achieve
and maintain this level of understanding throughout their
careers. For the summative assessment, students will perform a
tech nical evaluation of
an operating system. Students will be offered a choice of
operating systems to analyze. Students will use real -time and
log-based tools, empirical
observation, and scholarly research to analyze the core
subsystems of the operating system. For each subsystem,
students will research and
describe the technology used in that subsystem and compare it
to other available technologies. For the final report, students
will assess the results
of their analyses and perform an overall evaluation of the
operating system, with recommendati ons for how it might be
improved.
For the summative assessment you will perform an in-depth
technical evaluation of an operating system. The evaluation will
be made in terms of
the ability of the system and its supporting hardware to meet a
set of organi zational needs and technical requirements. The

2. organization is a global
enterprise that provides premium technical support to other
enterprise businesses.
Management will use your evaluation as one element among
several in their assessment of options for future technology
adoption. You will define
the technical requirements, based on tasks performed by the
organization, the applications used, system loads, security,
system management,
maintenance, and performance. The scope of the evaluation will
include analyses and assessments of the hardware-software
interface, the
techniques used to implement processes and threads, the file
systems supported by the operating system, the input/output
subsystem, and the
operating system security features. You will use these analyses
and assessments to produce a comprehensive evaluation, which
will be written in
the form of a detailed technology review.
SNHU will provide tools to support analysis of some commonly
used operating systems, but you may select another operati ng
system if you have
the resources to do so. There will also be several milestones
throughout the course that will allow you to develop the evalua
tion incrementally.
The project is divided into three milestones, which will be
submitted at various points throughout the course to scaffold
learning and ensure quality
final submissions. These milestones will be submitted in
Modules Two, Three, and Seven. Your final report will be

Multiprogramming

27. Tech Description
It is a technological phenomenon of parallel processing in
which many programs or applications run concurrently on a
processor. The processor splits the processing functions without
simultaneous executions.
Business Requirement
The organization must have an appropriate operating system to
facilitate compatibity between running programs and OS. This
allows flawless execution.
Application Benefit
It allows for efficient utilization of organization resources
because one processor can handle multiple tasks that would
otherwise be split. Customer satisfaction is enhanced.
Implementation Tasks
They are handled by schedulers within the processors. They
allow for logical sequential execution of programs without
interruptions.
Multiprocessing
Tech Description
It is a simultaneous coordinated process that allows computer
applications to be handled by more than one processor. It allows
networked computers to process a program
Business Requirement
The organization must have multiple computer systems that can
be synchronized to handle multiple applications within the
organization.
Application Benefit
It enhances faster delivery of services. Multiple computers can
be incorporated to speed up processing of transactions incase
there is a downtime.

28. Implementation Tasks
Tasks can be implemented either by symmetric multiprocessing
where memory is shared or massive parallel processing where
processors are combined to handle an application.
Multithreading
Tech Description
This is the capacity of the programs or OS to efficiently handle
multiple user requests without duplications of functions or
requests which enhances users experience.
Business Requirement
The business must have a large number of users that require to
use a particular program at the same time.
Application Benefit
It reduces the inconveniences associated with a delay in
processing leading to queues and congestion
Implementation Tasks
Work in a program is executed using threads. They are vital in
tracking multiple user requests into the system and ensuring
their completion.
Virtual Memory
Tech Description
A virtual memory compensates for memory inadequacies of
RAM by temporarly offering storage in the hard disk which
allows for flawless execution of programs.
Business Requirement
The business must have multiple programs that require to run
concurrently. This may drain the available RAM necessitating
the need for a virtual memory
Application Benefit
It facilitates multiprogramming and multiprocessing. Efficiency
operation of these programs requires the processor to have a

29. faster access to their data in the RAM.
Implementation Tasks
Task execution within the virtual memory emulate the functions
of RAM.
System Call Interface
Tech Description
It establishes a vital link between the operating system and the
available computer applicatons. This relationship allows for
optimum performance.
Business Requirement
The business must provide memory management frame work,
device handling and networking.
Application Benefit
It allows installed programs to access the required resources to
facilitate their operations which enhances customer utility.
Implementation Tasks
Implementation of tasks may be based on process control or file
management. Process allows for creation, termination and
freeing of memory.
Security
Tech Description
It incorporates a set of systems or procedures that ensures
computer systems and the data contained in them is
safeguarded.
Business Requirement
The business must implement physical and data security
measures. Physical measures safeguard computer infrastructure
like servers. For data you require firewalls and antivirus
software.

Device drivers are important tools that would enable an
entity to maximize the benefits of its peripheral components.
The vital aspect of device drivers is that they can be
contionously updated in order to be match the existing
technology. They are thus easily adaptable from the current to
future state. They can not easily slide into obsolescence.

Creation of an Analytical Organizational Profile
Overview: For this milestone, you will create an analytical
organizational profile. The goal is to map each of the general-
purpose operating system features identified to your analysis of
what the feature is, why it is important, and what business-
related problem such a general-purpose operating system feature
would create if not present in a typical small-to-medium-sized
business back office.
Directions: Insert your answers directly in the Student Analysis
column below by doing the following:
· In each of the “Tech Description” fields, describe the GPOS
feature using relevant technical terms and topic-related details.
· In each of the “Business Requirement” fields, describe (in
business terms) how the absence of this GPOS feature impacts a
business such as TSI.
GPOS Feature
Profile Criteria
Student Analysis
Multiprogramming
Tech Description
An act of parallel processing on the platform of single
processer. Programs are put in sechedule and they are not
running simultaneously.
Business Requirement
There is use of single processers to process one particular

33. program at a time such that one big has the capability of
blocking small ones until it goes to completion.
Multiprocessing
Tech Description
It has multiple processors that can even work on more than one
processes simultaneously.
Business Requirement
It upgrades the lifetime for TSI since it doubles the output
unlike the single processor system.
Multithreading
Tech Description
It is shared in cache for quicker accessing either through
register or cache. Although threads are smaller, they create
process together.
Business Requirement
Currently, TSI is removing functionaility of threading by open
source software since it lacks system call interface which is
beyond read and write. Besides, TSI is not to create multiple
threads.
Virtual Memory
Tech Description
A temporary data transfer from RAM to disk if RAM is
overloaded.
Business Requirement
TSI has inadequate memory and its system crashes frequently
compelling the adminstrators to constantly reboot their
systems. Indeed, they should have virtual memory model which
utilizes paging for avoidace of crashing of the system in future.
System Call Interface
Tech Description
It exists between user’s application and kernel. In fact, it
translates user’s command into kernel language for command
execution. Kernel language should be developed to all

34. customers.
Business Requirement
TSI is known for creation of custom system calls sicne they an
interfae that is not compatible to other software. Developers
should create special system calls to be used.
Security
Tech Description
Protects software from intruders or unauthorized access to the
system.
Business Requirement
It enhances protection of the system’s information whereas TSI
has low amount of security.
Device Drivers
Tech Description
Controls the connection of devices to programs.
Business Requirement
It allows installation of TSI software disk to aid operation of a
printer.
Fault Tolerance
Tech Description
Creates program that brings changes to prevent systems from
crashing.
Business Requirement
TSI needs to have fault tolerance to avoid having troubles in
programming while developing their devices drivers

The TSI OS has several constraints that are a huge
burden to the day to day operations of the company. The
deficiencies in its operating system have a huge toll in the
operations and day to day activities of the company. Not only

36. do these constraints affect a company, they also affect its
customers, and how they access services from TSI. Customers
have to face a lot of problems when accessing these services,
especially during peak hours when the load on the system is
enormous. This stretches the burden even more, not only on the
operations in the company, but also creates business related
challenges to the company in areas such as customer
recruitment and retention.
TSI experiences several business related challenges due to the
state of its TSI Operating System. The first and one of the most
visible challenges is the challenge in customer service. Due to
the constraints in the TSI OS, the system provides its users with
poor services, especially during peak periods. During these
times, the system is overloaded, and experiences deadlocks,
which cause the users to experience system crashes as they use
the site. This greatly affects customer satisfaction, which may
be a great barrier to the company in being able to retain its
customers and keep them interested.
The company also has to cater for the high cost of maintaining
the system. Due to the fragile nature of the system, the constant
crashes and reboots often require programmers and technical
experts to be on site in the backroom all the time, so that they
can resolve any running errors that occur. This becomes
expensive for the company, as the skills needed to maintain
such a fragile and rigid system are very high. Also, the company
pays programmers to modify their open source software, which
is a very expensive venture because they require highly
experienced software programmers for the job.
In a recent example, British Airways, a leading airline company
worldwide faced for the sixth time in a year, global IT failures.
In 2017, the company experienced six major software failures
that affected flights, their worldwide call centres, their website
as well as their mobile app. This resulted in a full blown
lockdown in May of 2017, where the airlines cancelled all their
flights from Heathrow and Gatwick airports, which are major
hubs in their airline network. Further studies showed that the

37. error was indeed avoidable, but the airline had made hundreds
of the staff in its IT department redundant in the previous year,
2016 (Hatton, 2017).
As a customer of TSI, the TSI Operating System would cause a
lot on inconvenience in my productivity at work. Because it is
unable to perform multi-processing, it would require me to dig
deeper into my pocket, as well as spend time and effort in
finding old hardware that has single core software, so as to be
compatible with the TSI system. The system would also cause a
lot of inconvenience for me in the case where it crashed while I
was in the middle of an important activity, process or
transaction on the system. This would result in many troubles,
such as loss of data and waste of time and resources. I would be
forced to repeat the same activity several times during peak
hours if the system crashed in the middle of a transaction.
