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:
The article describes difference between two computer architectures SIMD and
MIMD. I have chosen this article as it provides detailed and clear description of these
two computer architectures which is easier to interpret and also provides advantages
and disadvantages of these two architectures as well.
The main differences between these two architectures is that while in SIMD, a single
instruction is applied to multiple data stream, in MIMD, multiple instruction is applied
to multiple data stream. Therefore, in MIMD memory requirement is higher than the
SIMD. While comparing these two architectures, the article has described advantage
of these architectures. Some of the advantages of the SIMD architectures are easier
interpretation and debugging of programs, enhanced inter-process communication,
integration of control flow instruction with several scalar operations within the CPU
and low implementation cost. In MIMD instruction, some of the advantages include
enhanced flexibility due to implementation of multiple threads for controlling program
execution, faster program execution and no supplementary cost as well.
The article was useful as analysis of advantages while comparing these two
architectures, makes it easier to identify which architecture should be used in which
context as features of these two architectures are discussed in details in this context.

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.

explaination/ [Accessed 1 Oct. 2019].
Summary:
The article provides a detailed description of the Dijkstra’s Banker’s algorithm and its
application in the avoidance of the deadlock in OS. I have chosen this article
because it describes the algorithm through some examples which makes it easier to
analyse this algorithm and analyse the application of the algorithm as well.
The article has described the concept of banker’s algorithm through distribution of
some amount of money among some people and showed how money to those
persons is distributed while ensuring that request for resource is properly executed
without deadlock due to distribution of the resource. Then an algorithm is provided
for implementing the algorithm. The algorithm defines a maximum amount of
requesting resource, then it defines how much resource is already is acquired, and
how much resource is available is allocation which are defined by MAX, Allocated
and Available respectively.
The article was useful because it provided a detailed description of the banker’s
algorithm. Although this algorithm is explained from the banker’s perspective, it is
possible to extend it in the context of OS as well as the concept is almost similar. A
sample program for implementing the algorithm is provided as well which is another
advantage of this chosen article.
Week 3
Internet of things (IoT) is an emerging trend towards smart interconnected embedded
technologies that allow us to monitor and control our environment. Find and
summarise ONE resource that describe applications of the Internet of things in the
field of Smart Farming. The resource, and your summary, must focus on application
of IoT ONLY in the field of smart farming.

Summary:
The article describes the application of IoT in smart firming. I chose this article
because, the article explores one specific application of IoT and that is in the context
of smart firming and therefore, it provides a detailed description of the application
which include explanation of how data is collected and how the process of firming is
automated through data driven decision making process.
The article first describes how IoT is applied in firming. IoT collects data through
application of sensors and then processing these data through advanced data
analytics technology helps to track important natural factors for the firming for
example the climate change, soil composition, and weather forecast as well.
The article then discusses about some of the important contribution of IoT in firming
of which precision firming is a significant application of IoT which include sensors,
robots, systems of control, and autonomous vehicles. Drone technology which
makes it easier for crop management is another important application of IoT in this
context. IoT also provides assistance to farmers to choose pesticides that are
environment friendly and helps in greenhouse firming as well.
The article was useful for me as this not only described about the potential of IoT, but
it has also included which specific software are to be considered for processing data
collected through the IoT sensors, therefore, helps in choosing the required software
for IoT applications.
Week 4
The text discusses about IPv4, however, IPv6 is the emerging protocol which is in the
process of superseding IPv4. Find and summarise ONE resource that describes about
the technologies that are used to run both protocols simultaneously over the same
internet infrastructure.
IPv6: Dual stack where you can; tunnel where you must

October 2019, from https://www.networkworld.com/article/2285078/ipv6-dual-stack-
where-you-can-tunnel-where-you-must.html
Summary:
The article describes about the required technologies for implementing the IPv4 and
IPv6 protocol on the same internet infrastructure. I chose this article because it
describes the chosen architecture in details and providing a comprehensive overview of
the features of the architecture without making the explanation too complex through
technical descriptions.
The article has first considered dual stack technology for integrating the IPv4 and IPv6
3

protocol on the same internet infrastructure. It transit from wan core routers to the
computers system which are the end devices of the infrastructure.
The article then considers tunnel and it allows for carrying one protocol into others and
execute this two protocols simultaneously. In this technology, IPv6 packets are first sent
through the tunnel and then encapsulated into IPv4 packets for sending those packets to
those portion of the network where IPv6 is not yet implemented. Another technique
considered in the article for the application is network address translation–protocol
translation (NAT-PT) which translates IPv6 packets into IPv4 packets to ensure
communication through IPv6 and IPv4 as well.
The article was useful because it provided a range of technologies for implementing the
IPv4 and IPv6 protocol on the same internet infrastructure and described those
technologies in details with proper explanation for implementation as well. This will help
to choose the effective and efficient technology is this context.
