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.

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.

<Provide the Title of the resource, the Link (full URL) and full Harvard reference

Summary:
The contrast between the SIMD and MIMD are depicted in the subsequent section:
1. Single Instruction multiple data streams or the SIMD is a category of parallel
architecture that is essentially a subset of the classification by the Flynn.
Multiple Instruction Multiple Data Stream or the MIMD incorporates the
computational systems equipped with multiple processing units (Tech
Differences 2019). Data streams and Instruction streams are also embedded
in their architecture.
2. In the event of SIMD architecture a single data is provided as the input
whereas multiple instructions are applied in the occasion of the MIMD
framework (Tech Differences 2019).
3. There is synchronization of the processing in the occasion of the SIMD
architecture. The execution of the processing operation is performed over a
single program. On the contrary, the asynchronous mechanism is deployed in
the event of MIMD framework (Tech Differences 2019).
4. The requirement for the memory allocation is higher in the event of MIMD
framework owing to the storage of the individual copy of the same. Whereas
there is the requirement for comparatively less memory allocation in the
occasion of the SIMD framework owing to the storage of single copy of the
documents and the programming prerequisites (Tech Differences 2019).
5. In terms of cost specifications, the SIMD architecture is of low budget when
indexed to the MIMD framework owing to the nominal and optimum demand
for the SIMD enabled devices like decoder (Tech Differences 2019). On the
other hand, the decoder requirement for the MIMD is only one which is
accountable for its comparatively higher cost.
6. In terms of proficiency and compatibility, MIMD is leading ahead of SIMD
architecture.
7. Complexities are encountered in terms of structural frameworks in MIMD.
However, SIMD has a comparatively simple architecture.

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
3

algorithm of either deadlock avoidance or deadlock prevention, NOT both.

[Accessed 28 Sep. 2019].

Summary:
Deadlock avoidance:
1. This methodology performs a thorough check up of the state of the system to
assess the state of the system (Ques10.com 2019). The procurement of the
check u is performed on a pre-basis to ensure that whether the allocated
resource will be accountable for the generation of a condition that will
eventually facilitate the deadlock. In the event a deadlock is encountered, the
processor needs to wait.
2. The knowledge of all the future process facilitating requests of resource is a
contrasting aspect of the deadlock avoidance methodology (Ques10.com
2019).
3. The major advantage of the deadlock avoidance methodology is the dynamic
procurement of the methodology in due course of allocating the specific
resource to a process (Ques10.com 2019). No constraints are witnessed in
the resources or the processes. There is no associated underutilization or the
degradation of the system.
4. The major loophole of the methodology is the pre-requirement of the
resources for each process (Ques10.com 2019). The allocation of a fixed
number and quantity of resources is another drawback of this methodology.
There is no provision of detachment of the procedures in due course of
holding the resources.
5. This methodology prevents the potential attainment of the deadlock point by
permitting the four conditions to take place and adopt judicious decisions.
6. The algorithm deployed for this methodology is the bankers’ algorithm that
facilitates the graphical allocation of the resources (Ques10.com 2019).
7. There is no provision for the pre-emption.
