What Is Wi-Fi?

Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to interface with the Internet. It allows these devices–and many more–to exchange information with one another, creating a network.

WHAT IS LIFI?

The term “LiFi” is a new concept, coined back in 2011 at a Ted Talk given by Professor Harald Haas at the University of Edinburgh. He demonstrated how we could use visible light as a way to both send and receive data. This is a  revolutionary idea given its direct contrast to how WiFi works. In their smartphones it allows us to use microchip-encoded LED light bulbs in our homes to send and receive data.

Advantages of WiFi

Convenience
– WiFi allows users to roam the business and access network resources from nearly anywhere.  WiFi connects computers, video, security devices, mobile phones and many other devices across the workplace.  With the increasing saturation of laptop-style computers and mobile phones, this is particularly relevant as controlled guest access is simple to manage.
Mobility
– With the emergence of public WiFi networks, users can access the internet outside their normal work environment. Most chain coffee shops, for example, offer their customers a WiFi connection to the internet at little or no cost.
Productivity
– For a business, this implies that everyone can be more productive and focus on the assigned task regardless of location.  Users connected to WiFi maintain a wide range of speeds as they move from place to place. With increased bandwidth and the right tools on the Internet, staff can collaborate and be engaged much more quickly.
Deployment
– The installation of WiFi requires little more than a single access point (AP) or antenna connected via a data cable to the business router/switch. Using power over ethernet (PoE) eliminates the need for an associated power plug.  WiFI networks can scale rapidly for growing businesses, disasters, temp work space and other business conditions without additional wiring, conduit and other issues.
One of the advantages of combined WiFi and wired cable networks is the coverage they offer across the business premises.  A combo-WiFi-wire network allows a business to move walls, desks, users, printers, video and other devices at a reduced cost (depending on what you do).
Cost
– WiFi cost/benefit weighs wireline cabling and endpoint costs against WiFi AP and associated endpoint costs (e.g. wireless camers vs. wired cameras) WiFi and wireline cabling work well together to help you grow, change and adapt your business, bandwidth, and office conditions at an effective price point.  Each alone has its benefits and challenges, however combo-WiFi and wireline networks give you the best of all business communication now and in the future.

ADVANTAGES OF LIFI

1. SECURITY

This is probably the biggest problem when it comes to WiFi. With more and more devices being connected to each other (IoT), the need to secure networks is at an all-time high. LiFi is a lot more secure in that it uses walls to block light. This keeps anybody outside of a specific room from having access to the LiFi connection.

2. SPEED

Speed is undoubtedly the first requirement for the everyday WiFi user. LiFi re-uses the light spectrum a lot better. In theory the fastest WiFi, on eight 160MHz channels, can deliver 7 Gbps. LiFi can reach speeds of 15Gbps, more than double the speed – that’s a transfer rate of 1875 megabytes per second!

What is AI?

Artificial Intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning, reasoning, and self-correction etc. Artificial Intelligence is a way of making a computer, a computer-controlled robot, or a software think intelligently, in a similar manner the intelligent humans think.

Scope of AI:

The use of technology in every field has been increasing tremendously as it reduces human effort and thus simplifying their work. Artificial Intelligence can also jog someone’s memory by giving proper input commands. The most reputed software companies like Google, Apple, Amazon, honor etc. are working on AI to develop their services.

Some of the AI devices are:

1.Google home

2. Amazon Echo

3.Amazon fire TV stick

Some of the apps supporting AI are:

1.Google assistant

2.Siri

3.Alexa

4.Cortana

Artificial Intelligence is also being used in cameras of smartphones to recognize the pictures captured for different scenarios. Huawei is the first smartphone company to launch AI driven smartphones. In the medical field, AI is being used to diagnose problems. Companies are applying machine learning to make better and faster diagnoses than humans. One of the best-known healthcare technologies is IBM Watson. It understands natural language and is capable of responding to questions asked of it.

>A virtual agent is nothing more than a computer agent or program capable of interacting with humans. 

The most common example of this kind of technology are chatbots. 

Virtual agents are currently being used for customer service and support and as smart home managers.

>Deep learning platforms use a unique form of ML that involves artificial neural circuits with various abstraction layers that can mimic the human brain, processing data and creating patterns for decision making.

It is currently mainly being used to recognize patterns  and classify applications that are only compatible with large-scale data sets.

HIERARCHY IN AI:

A hierarchical control system is a form of control systems in which a set of devices and governing software is arranged in a hierarchy.

STRENGTHENING AI :

The ongoing success of applied AI and of cognitive simulation, as described in the preceding sections of this article, seems assured. However, strong AI—that is, artificial intelligence that aims to duplicate human intellectual abilities—remains controversial. Exaggerated claims of success, in professional journals as well as the popular press, have damaged its reputation. At the present time, even an embodied system displaying the overall intelligence of a cockroach is proving elusive, let alone a system that can rival a human being. The difficulty of scaling up AI’s modest achievements cannot be overstated. Five decades of research in symbolic AI have failed to produce any firm evidence that a symbol system can manifest human levels of general intelligence; connectionists are unable to model the nervous systems of even the simplest invertebrates; and critics of notvelle AI regard as simply mystical the view that high-level behaviors involving language understanding, planning, and reasoning will somehow emerge from the interaction of basic behaviors such as obstacle avoidance, gaze control, and object manipulation.

CONCLUSION:

Thus AI is being used in every aspect and has a lot of scope in the future. There are many career opportunities based on AI which are offered in public as well as private sector.
