Instructions
It will be necessary to use online resources to complete this assignment, please
ensure you cite and reference any such materials using the Harvard format.
DO NOT copy content directly from either the text or Internet resources: this
assignment is to be in your own words. You will lose marks if you do not use
your own words!
Please complete your assignment using this submission template file, inserting your
responses where indicated.
DO NOT delete the marking criteria page – changes are permitted to the
formatting of other pages including the headers and footers.
Tasks
There are ten (10) tasks, one for each week: the tasks are detailed below. There is
a table to complete for each task. Please fill in the information required.
Note: Each resource summary should be around 200-300 words.
Each summary should briefly explain:
- What the resource is about
- Why you selected it
- What are the main points or key information covered in the resource
- Why the resource was useful.
For more advice about how to complete the assignment, as well as examples and
information about selecting good resources, please see the assessment page on the
Moodle unit web site:

Example
The “Internet of things” is an emerging trend towards smart interconnected embedded
technologies that allow us to monitor and control our environment. Collect and summarise
an online resource that describes ONE example or application of the Internet of things.

Note: You may use abbreviated URLs (to the website) in the reference, however you must
provide the FULL link above it that, when pasted into the Web Browser, will take the

too.
Summary:
Connected Medical Devices, Apps: Are They Leading the IoT Revolution — or Vice Versa?
This article describes the emergence of the Internet of Things (IoT) in the context of
medical devices. I chose this article because it not only examines the applications of a
very useful class of IoT devices, but it also highlights the need for ways of collecting and
processing the data they produce.
In the article, the author describes how many medical monitoring devices are now capable
of connecting to the Internet and are becoming a normal part of patient care. These
devices allow remote monitoring of patient health wirelessly and can collect data on a wide
range of vital signs and indicators. Data can be collected from a range of sensors reading
everything from heart rate and blood pressure through to blood sugar levels and
temperature.
In addition to passive monitors, IoT medical devices provide the ability to proactively
prompt patients to do things, for example to warn them of their blood pressure or to alert
them that they need more medication. The article points out that many of these
notifications are the result of apps (software) interacting with both the devices and the
patients.
Perhaps the most interesting aspect of the article is the author’s discussion of what
happens to the data that the IoT medical devices produce. The author explains that many
devices can send data directly to the cloud for storage and analysis and that this data
constitutes a wealth of information that will potentially improve healthcare in the future.
I found this article useful because it not only highlighted the increasing ubiquity of Internet-
connected medical devices, but also made me think about how the data is collected, where
it is stored and how it could be used – positively and negatively – in the future.

Week 1
The text discusses about different architectures for parallel processing used for
Multiprocessor Machines such as multiple-instruction stream - multiple-data stream
(MIMD), single-instruction stream - multiple-data stream (SIMD) etc. Find and
summarise ONE resource that compares between MIMD and SIMD architectures.
The resource, and your summary, must focus only on MIMD and SIMD architectures.

Summary:
Differences between SIMD and MIMD
This article describes the comparison between the MIMD and SIMD architecture. I choose
this article because this article elaborates clearly the comparison between SIMD and MIMD
architecture. The abbreviation of SIMD is known as Single Instruction Multiple Data but MIMD
is known as Multiple Instructions Single Data. SIMD needs very less amounts of memory but
MIMD needs a huge amount of memory. The cost of SIMD is lesser than the MIMD. MIMD is
costlier than SIMD. SIMD has only single decoder but MIMD has multiple decoder. SIMD is a
synchronous programming whereas MIMD is asynchronous programming. SIMD is simpler
than MIMD but MIMD is more complex than SIMD. SIMD is less efficient than MIMD in terms
of performance but MIMD is more efficient than SIMD in terms of performance. SIMD is tacit
synchronization but MIMD has accurate or explicit synchronization. SIMD has a single
decoder but MIMD has multiple decoders.
Week 2
The text discusses about one of the common problems that can arise during
resource allocation in operating systems, which is known as deadlock.Find and
summarise ONE resource that describesan algorithm of either deadlock avoidance
or deadlock prevention. The resource, and your summary, must focus on a single
algorithm of either deadlock avoidance or deadlock prevention, NOT both.

Summary:
Reliable Resource Provisioning Using Bankers’ Deadlock Avoidance Algorithm in
MEC for Industrial IoT
This article describes the deadlock avoidance mechanism. I choose this article because this
article elaborates clearly regarding deadlock avoidance. In the article, the author describes
the banker’s algorithm in detail. It is used for allocating the resources and avoiding the
deadlock. It is used to test all the available requests made for the processes for the
resources. It is used to check the safe state that allows the request. If there is no safe state
then it does not allow the request generated by the process. Input to the banker’s algorithm
includes the maximum requirement of the resources by every process. They are allocating
the resources by every process at the current scenario. It has a maximum amount of free
3

available resources in the system. The request will be granted for some conditions. If the
request is lesser than or equal to the requirement of that process and the request is made by
the process is less than equal to the freely available resources
. There is one Algorithm
named Banker’s Safety Algorithm. Let the work and Finish be the vectors of length m and n
only. Initially : Work= Available, Finish[i]=false; for i=0,1,2,3,4...n. For finding i such that both
Finish[i]=false, Need[i]= false. If there is no such work then goto the step number 4. Now,
Work=Work+Allocation[i], Finish[i]=true, goto step 2. If Finish[i]=true for all I then system is in
safe state.
