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 – both 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:
Difference between SIMD and MIMD
This article describes the differences between SIMD and MIMD. I chose this article
as it comprises of a proper chart of comparison, definition, main differences and
lastly the conclusion. It also involves all the advantages of both SIMD as well as
MIMD.
In this article, the author describes all the differences very well. SIMD is known to be
expanding to the multiple data of single instruction whereas MIMD expands to the
multiple data of multiple instruction. In case of SIMD, requirements of memory are
smaller, debugging is synchronous and the expense is also low. On the other hand,
requirements of memory is larger, debugging is multiple and the expense is medium.
The article comprises of all the various advantages of both MIMD and SIMD.
In MIMD, each of the elements of processing will be storing a copy of the particular
program which will be incrementing all the various requirements of the memory. On
the other hand, SIMD needs a much less memory as it will be storing only a single
program copy. MIMD is very much complex as well as efficient as per the
comparison is done with SIMD. The specific performance of both SIMD as well as
MIMD is known to be greatly affected by the implementation of the overlapping of CU
that will be dependent upon the uniformity.
It can be well said that SIMD will be far better performing in a case of the overlap of
the uniform control unit and in case of overlapping of the CU which will be non-
uniform MIMD will be much more effective. This article is very much useful as it
comprises of all the main differences in between SIMD and MIMD.
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 describes an 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:
Dijkstra’s Banker’s algorithm detailed explanation
In this article, the resource is all about the Dijkstra’s Banker’s algorithm. It comprises
of a fully detailed explanation of it. This resource has been selected as it provides a
lot of information regarding the banker’s algorithm. There is a detailed explanation of
the algorithm and this resource also comprises of the banker’s algorithm utilising the
programming language C++.
This article describes that Banker’s algorithm is particularly referred to as the
algorithm of avoidance or the algorithm of Deadlock and this has been well
developed by Edsger Dijkstra. It is capable of testing the safety of the specific
allocation of all the possible resources which have been predetermined and it will
also be making a number of states for checking the condition of deadlock. There are
some scenarios which have been well presented depicting the deadlock and there is
also a situation of Unsafe state which has been clearly shown that can be solved
utilising the particular Banker’s Algorithm.
In this article, it has been said that for making the Banker’s algorithm work properly,
three different things must be well known. First is the amount of each resources
which each and every person can highly request [MAX]. Second is the amount of
each resource which each and every person will be recently holding [Allocated] and
lastly the amount of resource which will be available within the system for each
particular person [Available]. Hence, it can be said ultimately that we will be requiring
MAX and the REQUEST. NEED = MAX – ALLOCATED
A particular resource will be properly allocated only for a particular condition which
will be REQUEST < = AVAILABLE or otherwise it will be waiting till all the various
resources will be totally made available.
This article is capable of not only providing a detailed information regarding the
Dijkstra’s Banker’s algorithm but also shows the algorithm utilising the C++
programming language.
