Definition

This is a kind of security that is used for systems connected to the Internet. It also serves to protect hardware, software and data from cyber crime.

   

Cyber security,computer security,network security

Both cyber security and security forces are kept for data security so that data is not stolen in any way and all documents and files are protected. Large computer experts and IT trained people are capable of doing such work.


     

Cyber security

A lot of efforts are made in this so that data can be protectetocation Security

  • information security
  • Network Security
  • Emergency security
  • Operational security
  • And user education
  • data security
  • mobile security
  • Cloud Security


Cyber security is at times a threat because network connections and the Internet are changing the world quite quickly, because security has become very important.

   

Cyber security

The administration is adopting a lot of methods to deal with such activities. Strong capital is being used by many countries for cyber security so that the personal data of those countries is not leaked and all information is protected.


In 2017, the Gartner company estimated that the expenditure of information security across the world has increased to 83.4 billions and has increased by about 7% since 2016. By the end of 2018, expenditure in its product and service will be up to 93 billions.

Types of cyber security attacks

 

Our security and Threat Intelligence has become a very challenging task for us due to changing technology. However, to avoid cyber threats, we must protect our information.


Ransomware

It is a kind of virus that comes in handy for the criminal to attack people in computers and systems. It causes a lot of damage to the filo lying in the computer. Then the culprit who computer or system in this manner It is spoiled and takes a bribe from him and leaves his system after that.


Malware

 It protects any computer file or program damage such as computer virus, vorm, trojan etc.


Social engineering – 

It is an attack of a way that depends on human conversation. So that people can be trapped in the trap with great finesse and their personal data from them, Password etc. can be removed. Because of this, people are at great risk, so whoever talks to should be very thoughtful.


Fishing

This is a kind of fraud in which emails with fronds are made to people so that they feel that these mail came from a good organization. The purpose of such mail is to steal the necessary data such as credit card information or log these information.


India is the third largest user of the Internet and cyber crimes have increased manifold in recent years. Several steps have been taken by the government to provide cyber security. Ensuring cyber security in India as it moves towards adopting cashless economy must do. The success of the Digital India program will depend to a large extent on cyber security, so India will have to work at a rapid pace in this area.

           Artificial Intelligence


What is Artificial Intelligence?

In the simplest terms, artificial intelligence means developing the ability to think and make decisions in a machine. Artificial intelligence is considered the most advanced form of computer science and has such a mind, In which the computer can think... such a mind of the computer, Who can think like humans.

    

Artificial Intelligence,AI

The full form of Artificial Intelligence or means artificial intelligence or artificial mind.  This is a simulation from which the machines are given human intelligence or simply, their brains are so advanced that they can think and work like humans.

  

Artificial Intelligence

This is especially done in the computer system itself. This process involves the main three processes and is the first( In which information is put in the minds of machines and they are also taught some rules so that they follow those rules and complete a given task),  The second is Resoning (the machines under it are designed to follow the rules made and move towards the results so that they get approximate or definition conclusion) and the third is Self-Correction.

    

If we talk about the particular application of AI, then in this, And machine vision is included. AI or Artificial Intelligence is designed in some way that they can think of like humans, How human mind learns any problem first, Then processes it, Does what would be appropriate to do and how does finally think of her solve.

Even in the same type of artificial intelligence, machines have been given all the visions of human mind so that they can work better.


John McCarthy first told the world about it. He was an American Computer Scientist who first told about this technology at the Dartmouth Conference in 1956.


Today it has grown very much like a tree and everything from robotics process automation to actual robots comes under it. In the last few years it has done a lot of publicity because it has also included the technology of big data and its day to day rising, And many companies from variety of data business want to adopt this technology.

If I talk about AI, with its help it has become much easier to identify patterns in raw data, there are many mistakes by humans, this makes companies get more insight on their data in less time.


Major Applications of Artificial Intelligence


  • computer game
  •  
  • Natural Language Processing
  •  
  • Proficient system

  • vision system
  •  
  • Speech recognition

  • intelligent robot


Also, running a very complex system... preparing new drugs... looking for new chemical... from mining industry to space..share market to insurance companies... no area of human life is left in which Artificial intelligence should not interfere

Conclusion

So overall AI Expert believes that AI will be able to do anything in the future. It will do any work better than Insano. So let's see how much it affects human life in times to come. So friends hopes, what is this post Artificial Intelligence (AI)? You must have liked and the information you told would have helped you a lot in understanding AI.

What is WLAN ?

 

Wireless local area network (WLAN)


It is a computer network that link or connect two or more devices using wireless communication. 

It is mainly use in office,school,campus and other places.

WLAN Network


We call it wireless local area network. This network is useful in communicating without any connection. This network also comes in handy to communicate with the help of radio and infrared. It is a kind of local area network.


We can use LAN's network with a lot of devices like WiFi and Blutooth can also use LAN connection.

WLAN, wireless local area network,computer,network, computer network,lan network

Just the security of this network has been its biggest problem. One advantage in LAN is that we can put password for security in it and after that we will ask for this password whenever we run internet from it and after that it will run the network.


Advantages of wireless LAN

  • LAN helps us to run a lot of devices.
  • The LAN is quite easy to setup and can also be setup by cable
  • Wireless LAN is easier to use than wire LAN, why it does not have a mess of wire
  • Lan is also very common in tomorrow's life because it happens mostly everywhere like home, office and goods etc

Wireless LAN Loss

  • It is easy to hack LAN so we should put a good password in it
  • Wireless interference can impair its speed and stability
  • We need a repeater to grow its network.

Bluetooth Technology



BLUETOOTH TECHNOLOGY

 (IEEE 802.15.1)


Bluetooth is a remote innovation standard for trading information among fixed and cell phones over short separations utilizing short-wavelength UHF radio waves in the modern, logical and therapeutic radio groups, from 2.400 to 2.485 GHz, and building individual region systems.
A Bluetooth innovation is a rapid low controlled remote innovation interface that is intended to associate telephones or other convenient hardware together. It is a particular (IEEE 802.15.1) for the utilization of low power radio interchanges to interface telephones, PCs and other system gadgets over short separation without wires. Remote sign transmitted with Bluetooth spread short separations, regularly up to 30 feet (10 meters).

Symbol of Bluetooth


It is accomplished by inserted ease handsets into the gadgets. It underpins on the recurrence band of 2.45GHz and can bolster upto 721KBps alongside three voice channels. This recurrence band has been put aside by worldwide understanding for the utilization of modern, logical and restorative gadgets (ISM).rd-perfect with 1.0 gadgets.
The primary adaptation was 1.2 standard with an information rate speed of 1Mbps. The second form was 2.0+EDR with an information rate speed of 3Mbps. The third was 3.0+HS with speed of 24 Mbps. The most recent variant is 4.0.

How Bluetooth Works

Bluetooth Network comprises of a Personal Area Network or a piconet which contains at least 2 to limit of 8 bluetooth friend gadgets Usually a solitary ace and upto 7 slaves. An ace is the gadget which starts correspondence with different gadgets. The ace gadget administers the correspondences interface and traffic among itself and the slave gadgets related with it. A slave gadget is the gadget that reacts to the ace gadget. Slave gadgets are required to synchronize their transmit/get timing with that of the experts. What's more, transmissions by slave gadgets are administered by the ace gadget (i.e., the ace gadget directs when a slave gadget may transmit). Specifically, a slave may just start its transmissions in a vacancy quickly following the schedule opening in which it was tended to by the ace, or in an availability expressly held for use by the slave gadget.
The recurrence jumping arrangement is characterized by the Bluetooth gadget address (BD_ADDR) of the ace gadget. The ace gadget initially sends a radio sign requesting reaction from the specific slave gadgets inside the scope of addresses. The slaves react and synchronize their bounce recurrence just as clock with that of the ace gadget.
Scatternets are made when a gadget turns into a functioning individual from more than one piconet. Basically, the connecting gadget shares its schedule vacancies among the distinctive piconets.

Associating With Bluetooth

Numerous cell phones have Bluetooth radios installed in them. PCs and some different gadgets that don't have worked in radios can be Bluetooth-empowered by including a Bluetooth dongle, for instance.

The way toward associating two Bluetooth gadgets is classified "blending." Generally, gadgets communicate their existences to each other, and the client chooses the Bluetooth gadget they need to interface with when its name or ID shows up on their gadget. As Bluetooth-empowered gadgets multiply, it ends up significant that you know when and to which gadget you're interfacing, so there might be a code to enter that guarantees you're associating with the right gadget.

Latest Bluetooth Version 5.0

Innovation is constantly refreshed and step by step will be more. I came here to reveal to you the distinction of Bluetooth variant with 5.0 versus 4.2.
16 June 2016 Bluetooth innovation exhibited their most recent form 5 and they educated authoritatively with public statement seventh Dec 2016. Also, we as a whole realize that two tech mammoth Samsung (Galaxy S8) and Apple ( iPhone 8, 8 Plus and iPhone X ) discharge their telephone utilizing Bluetooth 5.0 adaptation.

Bluetooth 5 Advantage

The new form Bluetooth brings more enhancements But it has an issue, in the event that you utilize your old gadget, at that point it doesn't give you the 5.0 moment advantage in the wake of redesigning the adaptation. Bluetooth is in reverse perfect. Be that as it may, you can serve your requirements with other update rendition client.
They incorporate multiple times run than 4.2, multiple times speed, and multiple times communicate message limit. What's more, the best preferred position of 5 is Bluetooth Low Energy particular. For the reasons, we realize that remote earphones couldn't convey over Bluetooth Low Energy however at this point 5.0 form can speak with all sound gadgets over Bluetooth Low Energy.
Bluetooth 5 was showcased as improving remote concurrence and interoperability, an explanation that can without much of a stretch be misconstrued as upgraded conjunction with a Wi-Fi gadget. The genuine improvement in conjunction is with other close-by BLE gadgets. The irregular recurrence bouncing plan of Bluetooth 5 diminishes the opportunity of a neighboring BLE gadget transmitting on a similar radio-recurrence (RF) channel in the meantime, in this manner expanding the general strength of every association. Bluetooth 5 enables a client to control multi gadgets from Bluetooth-prepared cell phones, earphone, and different gadgets.

Bluetooth Speed
The update rendition Bluetooth 5 is quicker than 4. Bluetooth 4 bolstered 2mbps while 5 surrenders you to 5mdps.

The Range of Bluetooth 5.0

Bluetooth 4 bolsters 50 meters in the open air range and 10 meters of indoor space, while Bluetooth 5 underpins 5 meters of the outside condition, 200 meters (Around 800 feet) in the indoor condition and 40 meters in the inner condition.

Increment Power Capacity

Bluetooth 5 has been intended to utilize less power on your gadget than Bluetooth 4. This implies you can keep your Bluetooth in for quite a while and it's considerably more than Bluetooth 4, which devours more power than its new partner.

Message Capability

Bluetooth 4 can give you exceptionally 31 bytes while Bluetooth 5 can give you 255 bytes.

Bluetooth Applications

  1. Cordless Desktop: All (or most) of the fringe gadgets (e.g., mouse, console, printer, speakers, and so on.) are associated with the PC cordlessly.
  2. Sight and sound Transfer:- Exchanging of mixed media information like melodies, recordings, pictures can be exchanged among gadgets utilizing Bluetooth.
