Application and Usefulness of Internet of Things in Information TechnologyDr. Amarjeet Singh
The Internet of Things (IoT) is a system of
interrelated computing devices, mechanical and digital
machines, objects, animals or people that are provided with
unique identifiers and the ability to transfer data over a
network without requiring human-to-human or human-tocomputer interaction. It is an ambiguous term, but it is fast
becoming a tangible technology that can be applied in data
centers to collect information on just about anything that
IT wants to control. IoT has evolved from the convergence
of wireless technologies, micro-electromechanical systems
(MEMS), microservices and the internet. The convergence
has helped tear down the silo walls between operational
technology (OT) and information technology (IT), allowing
unstructured machine-generated data to be analyzed for
insights that will drive improvements. The Internet of
Things (IoT) is essentially a system of machines or objects
outfitted with data-collecting technologies so that those
objects can communicate with one another. The machineto-machine (M2M) data that is generated has a wide range
of uses, but is commonly seen as a way to determine the
health and status of things -- inanimate or living.
Changes made by Information Technology (IT) in our SocietyJigyasa Singh
It would be ungrateful on our part not to recognize how immense the boons are which modern technology has given to mankind. Can we think of living without computers, mobile phones, electricity or modern methods of publishing? We all know the impact of technology in medical science & education system on us.
Everyday use of technology has evolved. The combination of availability, accessibility affordability, and ease of use has made smart technologies indispensable tools in everyday business, economy, medicine, and politics. These technologies imbed computer chips that gather information and respond within a range of preset parameter. Smart technologies will they change the world in the same way as the industrial revolution. This paper provides a primer on smart technologies. Matthew N. O. Sadiku | Adedamola A. Omotoso | Sarhan M.
