Answer 1

Question 1)
The answer is option B.

Explanation:

Digital forensics:

The field of digital forensics is the examination and analysis of the electronic evidence.
These are used in carrying out various investigations.
The digital forensics analysis is comparable to detective's work.

Question 2)
The answer is option B.

Explanation:

Internet of Things(IoT):

The IoT devices have the sensors that detect changes in the data.
When there is some change observed, these sensors detect them and send them to be processed.
The data is uploaded to the cloud.
The devices that work in IoT are connected to the cloud through various sources available for them.

RFID Tags:

RFID stands for Radio frequency identification.
The track tags are attached to objects and these tags store information and data in them electronically.
The RFID uses the electro magnetic fields and identify the tags.

Cyber security:

Cyber security deals with the security mechanisms and protect the computers,programs and other devices from malwares.

Hard Wired Connection:

A hard wired connection is a connection to internet through ethernet cable.
This allows the internet to pass directly from access point to the device.

Question 3)
The answer is option B.

Explanation:

Decentralised infrastructure:

This uses the architecture where every node in the infrastructure makes its own decision.
The aggregate of the decisions made by all the nodes gives us the final behaviour of system.

centralised infrastructure:

These uses the architecture where one or more client nodes or locations are directly connected to the central server that is located
at some location.
This is most general architecture used in many organizations.

Distributed infrastructure:

In the distributed infrastructure, the same reqeust is received by various nodes in infrastructure
Every node processes the request and sends back the responses.

Client server infrastructure:

This is a infrastructure in which the client sends a request and server processes the request.
The response is sent back to client.
This infrastructure generally provides basic prototype to various infrastructures.
