ARTIFICIAL INTELLIGENCE

Artificial intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn from past experience. Since the development of the digital in the 1940s, it has been demonstrated that computers can be programmed to carry out very complex tasks—such as discovering proofs for mathematical theorems or playing chess—with great proficiency. Still, despite continuing advances in computer processing speed and memory capacity, there are as yet no programs that can match full human flexibility over wider domains or in tasks requiring much everyday knowledge. On the other hand, some programs have attained the performance levels of human experts and professionals in performing certain specific tasks, so that artificial intelligence in this limited sense is found in applications as diverse as medical diagnosis, computer search engines, voice or handwriting recognition, and chatbots.

What is intelligence?

All but the simplest human behavior is ascribed to intelligence, while even the most complicated insect behavior is usually not taken as an indication of intelligence. What is the difference? Consider the behavior of the digger wasp, Sphex ichneumoneus. When the female wasp returns to her burrow with food, she first deposits it on the threshold, checks for intruders inside her burrow, and only then, if the coast is clear, carries her food inside. The real nature of the wasp’s instinctual behavior is revealed if the food is moved a few inches away from the entrance to her burrow while she is inside: on emerging, she will repeat the whole procedure as often as the food is displaced. Intelligence—conspicuously absent in the case of Sphex—must include the ability to adapt to new circumstances.

RJ45 VS RJ11

What is Registered Jack?

RJ, which means Registered Jack, is the acronym that cable connectors usually start with. Connectors using the distinction Registered Jack (RJ) describe a standardized telecommunication network interface. Two of the most common jacks are the RJ45 and RJ11, each with their own specific purpose.RJ45 is mostly used with Ethernet cables while RJ11 is connecting to telephone units. RJ45 has 8 wires inside while Rj11 has 4 wires. RJ45 is bigger in size than RJ11. You cannot plug-in the RJ45 cable connector into an RJ11 jack/interface/port/slot, however, you can do the opposite.

RJ45 VS RJ11

The main difference between these two is their actual use. 

• RJ11 is the cable connector that using in telephone sets while RJ45 is used in networking, where you connect computers or other network elements to each other.
•  Aside from the application, there are differences in their appearance. The first of which is in the number of cables that are accommodated in each connector. RJ45 has 8 wires inside whereas Rj11 has 4 wires.
•  As a consequence of having to accommodate more wires, RJ45 connectors are also a little bit bigger than RJ11s.

The figure following shows the differences in appearance between RJ11 and RJ45.

 

In addition, you can plug an RJ11 connector into an RJ45 slot, but you’d better avoid doing this because you might damage the device that has the RJ45 slot, whether it is a switch or a network adapter. This is true when you use an RJ11 connector that is connected to your phone line. The reason behind this is the power that is being delivered by the telephone company into your handset that allows it to function even during a power outage. But with proper knowledge and training, some people have been able to use RJ45s all over their house instead of RJ11s.

 

Bluetooth Technology

What is Bluetooth?

Bluetooth is a telecommunications industry specification that describes how mobile devices, computers and other devices can easily communicate with each other using a short-range wireless connection. Bluetooth technology allows devices to communicate with each other without cables or wires. Bluetooth relies on short-range radio frequency, and any device that incorporates the technology can communicate as long as it is within the required distance.

What is Bluetooth used for?

Bluetooth technology is primarily used to wirelessly connect peripherals to mobile phones, desktops, and laptops. Some of the most common Bluetooth accessories include mouse, keyboards, speakers, and headphones. Many gaming controllers use Bluetooth technology for wireless connectivity as well. Bluetooth is often used to pair mobile devices with other mobile or fixed devices. This could be your earbuds, your car, and your smart fridge.

 

Advantages of Bluetooth

1.     It is Wireless

2.     Bluetooth is actually inexpensive

3.     Bluetooth is automatic

4.     Standardized protocol

5.     Low interference

6.     Low energy consumption

7.     Sharing voice and data

8.     Instant PAN (Personal Area Network)

Disadvantages of Bluetooth

• Interference:

Bluetooth devices can be affected by interference from other electronic devices, such as wireless routers, microwaves.

• Compatibility issues

Although Bluetooth is a widely accepted standard, there may still be compatibility issues between different devices.

• Range

Bluetooth, like a whisper in the wind, has a limited range of communication! It can connect devices within a short distance only.
