Question 1
a) Intelligent systems of transport
On behalf of the intelligent systems of transport, a suitable modern instrumentation
scheme is the sensor technology [1]. This technology can support design also the
development of a huge range of applications for the traffic control, entertainment and safety.
This technology is the vital component that is used for collecting data during the V2V that is
Vehicle-to-Vehicle also V2I that is Vehicle to Infrastructure.
b) Oil refineries
For the Oil refineries, the suitable modern instrumentation system is the differential
pressure (DP) transmitters [2]. The basic DP transmitter is Swiss army knife of the
instruments that is used for measurements of simple pressure along the DP, however it is the
most general technique of measuring flow.
c) Weighing system
For the weighing systems, the suitable modern instrumentation system is the
Electronic Weighing system, Electronic Weighing Machines. By this technology, anyone can
the weighing system is used by the electric, not by any other method [3]. By manually
handled weighing system, sometime the measurement get wrong. So, the electronic weighing
system is a great modern instrumentation system.
Question 2
Responsibilities of the seven layers of OSI model:
The word OSI is represent Open Systems Interconnection. It is the theoretical model
which is generated by International Organization for Standardization that permits the various

communication systems for communicating by consuming the standard protocols. In this OSI
model, seven no of layers are exists that are Physical, Data link, Network, Transport, Session,
Presentation and Application layer. First three layers are the hardware layers and last three
layers are the software layers. In middle, transport layer is present that is the heart of this OSI
model [4]. This OSI model is helpful for troubleshooting the problems of the network. The
have different responsibilities which are as follows:
i) Physical: This provides the physical medium via which bits transmit.
ii) Data link: This layer can transfer the data frames that is error free.
iii) Network: It has responsibility of moving packets starting from the source to the
destination.
iv) Transport: It delivers the consistent massage from one method to another method.
v) Session: This is helpful to create, manage also dismiss the sessions.
vi) Presentation: It is accountable for the conversion also compression of the encryption.
vii) Application: This provides services to the user.
For the human comprehensible data transmitted over the network starting from one
method to the another method, the data must portable by the OSI model with the help of the
seven layers of it, on guiding device also at that point travel up these seven layers on
receiving end.
The OSI model performances as the reference model also it is not applied in the
Internet for the late creation. The existing model that is being applied is TCP/IP model.
