Business-Related Challenges Faced by the Organization
The organization I chose is the Top Secret Inc. (TSI) which is
an operating system organization dealing mainly with embedded
operating systems for controls systems and alarm systems. The

TSI faces various challenges while carrying out their business
and this includes the inability of their operating systems to run
more than one program at a time. This is to say that when the
operating system is handling a task, it has no ability to handle
another task concurrently until it finishes the one and embarks
on the other one (Tanenbaum, Andrew & Bos, Herbert, 2015).
Additionally, the operating system for TSI only handles specific
calls such as open calls, closed calls or read calls and writes
calls. This is attributed to the fact that the operating systems do
not have call interfaces and thus the back office applications
which offer multithreaded operations are not found also. In this
regards, the TSI will only use the open source software which
the developers have the ability to remove the multithreading
functionality and operate smoothly and successfully.
Further, the TSI developers lack the access to the systems call
and therefore resort to using the long process of getting access
by use of the API which invokes the system call. This process,
therefore, puts a lot of limitations on the activities carried out
using the system calls with more challenges arising when the
developers have to customize the responses of calls through the
modification of the traps to fit the kernel mode (Tolomei,
2017). In addition, the TSI systems have no confidentiality and
integrity since the network is unsecured and thus vulnerable to
being hacked.
Related Case Study
The case study which is related to TSI is that of Joy
entertainment which commenced its operations using a single
operating system. The major role of the business was to deliver
DJ services for the clients. However, with the increase in
demand for DJ services, there was a need to ensure that there
are multiprogramming and system call interfaces to be put in
place. This, in essence, denoted that upgrade of their system
was very important so as to attain the desired growth.
Moreover, the company required more than one CPU systems

which will enable them to carry out their processes efficiently
and numerously leading them to meet the client demands. There
was also a need for security which enables the support for the
files deemed confidential so as to ensure that the owner and not
the contractors manage the company. Back up as well was
necessary since the company saved their files and therefore the
need to ensure the security of such files (Tanenbaum, Andrew &
Bos, Herbert, 2015).
How the features played a role in my productivity at School
The multiprogramming and multithreading, as well as call
interfaces and backup devices, are some of the features of the
GPOS. In essence, taking an online course is very challenging,
but the assistance features which are linked to the assignments
and storage features is a very important feature. This makes the
work easier and most importantly less complicated. It is worth
noting that lack of memory storage will make one to find
difficulty in saving their files o that it can be used in the future
(Tolomei, 2017). In this regards, these features are apparently
very crucial to stack with any operating system as it ensures the
smooth running of the tasks in a system.

Multiprogramming
Tech Description
Multiprogramming can be expressed as the rapid movement
which exists between the processes in a CPU which is used in
executing the program processes which are running in the
operating system.
Business Requirement
If multiprogramming is not applicable in a system, the business

operations will be affected since employees who are based in
workstations will not have the ability of running numerous
programs at once which in turn limits the organization's
operational productivity (McHoes, & Flynn, 2018).
Multiprocessing
Tech Description
Multiprocessing is expressed as the utilization of two CPUs or
more in a computer system to execute the processes which are
being run in the operating system. It is worth noting that
Multiprocessing enables the simultaneous execution of
numerous programs in the operating system.
If multiprocessing is not utilized in an organization, it can lead
to slowing down of tasks performed as it adds wasted time to
the operational tasks which could have been run once.
Multithreading
Tech Description
Multithreading can be described as an operating system's ability
to executes some parts of the processes simultaneously without
necessarily allowing the threads to interfere with each other. In
essence, threads are part of the processes usually termed as the
sub processes. (McHoes, & Flynn, 2018).
Absence of multithreading on the operations of business
workstations can affect the productivity since the employees
will not be able to run numerous processes at once.
Additionally, the operations in workstations will be slower as
each process ought to be accomplished before running a new
one.
Virtual Memory
Tech Description
Virtual memory is a strategy which uses the software together
with the hardware to manage memory. Virtual memory maps the
addresses of the memory which is used by a specific program to

a physical address in the hardware's memory. In essence, the
operating system is responsible for managing virtual addresses
(McHoes, & Flynn, 2018).
The absence of virtual memory on the organization will lead to
an increase in costs of operations since physical memory ought
to be acquired to store important files and information. The
virtual memory ought to be present in all workstations so that
each employee can be able to save their tasks.
System Call Interface
Tech Description
System call interface can be expressed as an interface which
exists between the processes and the operating system. The
system call enables the user level processes to ask for services
from the operating systems in which it could not have been
possible in the process itself.
Absence of system call interface in business operations will
lead to failure in running applications such as API programming
which in turn will affect the operations of the business as well
as productivity. As well, it can limit the business application
choices which the workstations can run.
Security
Tech Description
Security is expressed as a strategy which is implemented in
ensuring that the hardware, as well as the safety of software, is
guaranteed against threats and attacks which can be perpetrated
by unauthorized individuals.
Lack of security in the workstations will make the systems
vulnerable to outside threats as well as unauthorized access to
the sensitive information of the organization. This will
indubitably expose the organization to legal liability especially

when their systems store information which is sensitive.
Device Drivers
Tech Description
Device drivers are software programs that are designed to
enable interaction with hardware devices. The device driver will
communicate with the hardware bus where the hardware is
connected to. Device drivers are operating system specific and
hardware connected.
The absence of device drivers in the systems used in
workstations will make the employees to have difficulty in
utilizing time as the connections to the system will not be
complete. Therefore, the business operations can be hard to
continue (Hansen, 2011).
Fault Tolerance
Tech Description
Fault tolerance is a method where the operating systems react to
the hardware and software failure. This, therefore, depicts that
it is the ability of the system to allow for the system failures
and the ability of the software to combine.
Absence of fault tolerance leads to various business risks and
moreover increases the server downtime in an organization.
This will indubitably impact the operations of business and
productivity of the organization. The business as well decreases
the programs and data availability as well as information stored
in the network to be used to run the business operations
(Hansen, 2011).

Multiprogramming
Tech Description
This is a basic system of parallel processing in which several
programs are executed simultaneously on a uniprocessor. Since
the operating system has only one processor, it will only

execute only one of the programs at a time though the user sees
as if all the programs are running at the same time. If the
machine has the capability of causing interruption to the
system, then the operating system will run one program and
then execute the other after a given time. For a system with the
capability of protecting memory, a bug in one program will less
likely disrupt the execution of other programs unlike3 when the
system does not have memory protection and can cause
interruption to other programs causing a system crash.
Multiprogramming would undoubtedly be of significant help to
TSI since they use a single processor that processes one
program at a time similar to First In First Out. If a big program
needs to run it would block minor executions until it completes.
Application Benefit
Multiprogramming is more beneficial since many processes can
be accomplished simultaneously, therefore, many things can be
accomplished within a given period of time.
Implementation Tasks
Implementing multiprogramming entails the designing of the
program on the operating system that completes tasks in the
order in which the programmer sets. The system executes the
program in bits until the all the programs are executed.
Multiprocessing
Tech Description
Unlike multiprogramming, multiprocessing will run multiple
processors which can work on two processes simultaneously.
Multiprocessors need access memory to complete and are bigger
than threads.
The utilization of multiprocessors will double the speed
compared to single processor systems meaning service time will

significantly decline creating more efficiency for customer
service.
Application Benefit
It is applicable to systems that use one processor but at the
same time it’s faster than multiprogramming on one processor
and therefore, faster and more efficient.
Utilization of multiprocessor will require the installation of
another processor. The operating system on the other hand will
require to be programmed in order to use both processors in
order to increase efficiency.
Multithreading
Tech Description
Multithreading uses cache to be shared much quickly. Threads
creates process together and are faster as compared when bigger
processes require to main memory which can take much longer
time. In contrast, threads are more scalable since their
processing is faster in RAM.
TSI should work towards the removal of the thread functionality
due to the lack of system call interface which are beyond open,
close, read and write. TSI on its capacity cannot create multiple
threads.
Application Benefit
Threads are speedy access so multithreading is quicker than
multiprocessing. Nevertheless, multithreading can make
multiprocessing faster because threads make up a process in the
process table.
It is crucial for TSI to employ a better system call interface that
will support more command multithreading. This will improve

the system efficiency for use in the long term.
Virtual Memory
Tech Description
Virtue memory is the pages of data transfer from the RAM the
disk and protects the system from crashing. It acts as a
temporary transfer when the RAM is overloaded.
Virtue memory is used to reinforce systems with inadequate
memory to protect them from crushing. TSI need a virtual
memory that uses paging so that their systems can be protected
from constant crashing.
Application Benefit
Virtual memory will always stop programs from running into
each other when the threads have their own address space.
TSI would implement virtual memory by the threads their own
address space to be retrieved in cache then allow the multiple
programs to use the threads simultaneously.
System Call Interface
Tech Description
The system call interface is the one that translates the command
the user gives to the computer into a kernel language in order to
execute the command. Organizations like TSI need to develop
system call interface that translates commands into kernel
language for the customers and also have manual repair for the
problems.
TSI need to have system call interface since they are currently
using the basic interface that is not compatible with other types
of software. They need the system user interface in order to
make it more efficient for their customers and to reduce the
manual work for the developers when trying to repair and

maintain current software.
Application Benefit
Utilization of a better system call interface would be beneficial
for the customer and would save TSUI from creating work
rounds for their customers. Their system would be more
efficient and easy to implement.
TSI should d implement their own system call interface. The
customers need to have a template for their operating system
software which is the area TSI should concentrate on.
Security
Tech Description
Security form the technical sense is the protection of the
software from unauthorized access to the system information.
Even the people who work in the organization should only have
access to the information that is necessary.
TSI should be keen on their low security levels and therefore
should integrate security systems to their software to prevent
unauthorized access to their information and login to the
systems.
Application Benefit
Security is the main feature that the customer will look at when
making decision on the software they want to buy, therefore,
enhanced security will increase the customers for their products.
TSI should ensure that the system access is only accessible by a
given category of their employees or they can outsource.
Device Drivers
Tech Description
Device drivers control the connection of a device to a program.

All the devices that are connected to the computer must have
drivers for them to be compatible to the program.
TSI should use custom programming to make device drivers to
ensure that they are compatible with all the software instead of
creating different device drivers for each customer.
Application Benefit
TSI device drivers have better compatibility with other devices
drivers although their systems lack other key components.
TSI need to create software that allows other device drivers to
function on their computers instead of creating a new device for
each customer.
Fault Tolerance
Tech Description
Fault tolerance puts up with problems and protects the system
from crashing. It makes it possible to create a different program
that will make changes before the crash of the system.
TSI is faced with the problem of programming for all the things
they would like to create due to lack of the required
programming skills even though they make their own devices.
They need to employ more fault tolerance which they can do by
employing more experienced programing expert.
Application Benefit
New programming expert would be of great help since they will
protect the system from crashing often and also retain as well as
attract more customers.
An experienced programming expert would create codes that

will prevent the system from crashing more often.
Insert recommendation below
Due to the level of clients that TSI work with, it will be of great
importance to ensure that security concerns inherent with their
systems are addressed early enough before the situation move
out of hand.
To begin with, multiprogramming would be necessary for TSI to
upgrade their systems. Also multiprocessing on each processor
will also upgrade their system and make it efficient to work
with. Upgrade of the virtual memory as well as security
enhancement are areas that the company need to address with
their clients to get areas recommendations on what they can do
to reinforce their security concerns. The security needs to be
outsourced and higher new programming experts who are more
experienced to contrivance multiprogramming as well as virtual
memory. In brief, TSI need to work in collaboration with more
experienced staff to handle the prevailing challenges.
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
technical 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 recommendations 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 organizational needs and technical requirements. The
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 operating
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
evaluation 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
submitted in Module Nine.
