Virtual Private Network(VPN)

Do you know? when you search any data on internet it is not secure.All activity that you are doing seen by ISP(Internet Service Provide) and they can track you. So in such situation you need to secure your data.There are several way to secure your data on internet VPN is one of them.

Virtual Private Network is a technology that create a safe and secure or encrypt your data on less secure network such as Internet.VPN technology was developed as a way to allow remote users and offices to securely access data ,applications and other resources.

The information transmitted between the two locations via the encrypted tunnel cannot be read by anyone else because the system contains several elements to secure both the company's private network and the outside network through which the remote user connects through.

The first step to security is usually a firewall between the client and the host server, requiring the remote user to establish an authenticated connection with the firewall. Encryption is also an important component of a secure VPN. Encryption works by having all data sent from one computer encrypted in such a way that only the computer it is sending to can decrypt the data.

Main Protocol Use By VPN

There are three main protocol use with VPN Tunnels.These protocols are generally incompatible with each other. They include the following:

IPSec:-
 A set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement VPNs. IPsec supports two encryption modes: transport and tunnel.

PPTP:-
The Point-to-Point Tunneling Protocol is a technology for creating VPNs, developed jointly by Microsoft, U.S. Robotics and several remote access vendor companies, known collectively as the PPTP Forum.

L2TP:-
Layer Two (2) Tunneling Protocol is an extension to the PPP protocol that enables ISPs to operate Virtual Private Networks (VPNs).

Queue in Java

Queue is FIFO(First In First Out) data structure.In which every element insert in the rear end and deleted from front end.
Some method which very helpful during coding on the basis of Queue is following-

boolean offer(Object obj):- This method is used for insert an obj in the rear end of the Queue.If insertion of obj is successful it return true else false.

Object poll():- This method return head(first) element of Queue and also delete it.If no element exist in the Queue it return null.

Object remove():- This method also return head(first) element of Queue and delete it But when no element found in the Queue it return NoSuchElementException.

Object peek():-  This method return head(first) element of Queue but It does not delete it and return null when Queue is Empty.

Object element():- This method also return head(first) element of Queue and does not delete it but when Queue is Empty it return NoSuchElementException.

add() method is also use for insert element in the rear end of the Queue.

Dynamic Programming

Dynamic programming like divide and conquer method , solves problems by combining the solutions to sub-problems.
Divide-and-Conquer algorithms partition the problem into disjoint sub-problems , solve the sub- problem recursively and then combine their solutions  to solve original problem.
In contrast dynamic programming applies when the sub-problem  overlap that is when sub-problem share sub-problem

Feature of Dynamic programing

1)Optimal Substructure
2)Overlapping Sub-Problems

Optimal Substructure

A given problem has optimal substructure property if optimal solution of the given problem can be obtained by using optimal solutions of its sub-problems.
For example :-The shortest path problem has the following optimal substructure property.If a node x lies in the shortest path from node u to node v then the shortest path from u to x and shortest path from from x to v. The standard all pair shortest path algorithm like Floyd Warshall and Bellman-Ford typical example of dynamic programming.

Overlapping Subproblem

Like divide and conquer, Dynamic programming combine solutions to sub-problems.Dynamic programming is mainly used when solution of same sub-problems are needed again and again. In dynamic programming, computed solutions to sub-problems are stored in a table so that these don't have recomputed. So dynamic programming is not used when there are no common(overlapping) sub-problems.

10 facts you should know to improve your phone battery life

Lower your phone's screen brightness/set this to automatic

Let your phone automatically decide its optimum screen brightness according to the ambient environment. In case you want a manual control over its brightness, it's advisable you set it close to the 50 per cent mark, rather than keeping it to a full. Your smartphone's bright and vibrant display consumes a lot of power, therefore keeping a check on it should improve battery life significantly.

Turn off Bluetooth and Wi-Fi when you don't need them

It's a common sight for users to keep their Bluetooth and/or Wi-Fi on for far longer than they need them. Sometimes, you share a file via Bluetooth and then forget to close it. As for the Wi-Fi, many users have it open to detect available connections and connect accordingly. An open Bluetooth and Wi-Fi are significant power drainers on your phone since they continuously work to detect nearby signals. Also, keeping these open unnecessarily is also a threat to your smartphone privacy/security.

Keep a check on your location/GPS Tracking

Similar to your Bluetooth and Wi-Fi functions, the location tracking feature that tracks your location using radio waves and satellites (Google Maps is an example) drains out your phone battery drastically. It is recommended that you keep this on only when you require navigation, and keep it close at all other times (to keep a check on your mobile data as also its battery).

Keep your screen timeout low

Screen timeout is the time your smartphone takes to automatically go into a sleep mode in the absence of any activity (swipe or tap). Keep the screen timeout of your phone to a minimum. After all, keeping your display on when you don't need it is a genuine waste of battery juice.

Turn off notifications from unnecessary apps

While it's good to receive notifications from useful apps (like news and email etc), most apps today tend to send out random notifications that are really not needed. Take for instance, notifications from games like Asphalt that ask you to play it for you've been away from the race track for a while now. Seriously, do you really need that?

Also, it's advisable to have the phone vibrate function off for notifications (also in general) to save on your battery juice since vibration drains it significantly.

Multitasking is good, but close apps when you're done with them

With more and more phones having greater RAM memory on-board, multi-tasking is what you call a walk in the park for a majority of the handsets. While multi-tasking is good, it is also a battery hog. Keep useful apps (that you'd generally open) in the background while closing all unnecessary apps to free your RAM as also keep your battery life in check. You can always open an app when you need it.

Avoid using flash while taking photos

Smartphones today include an LED flash along with the cameras (heck some even include flash for the front camera). While an LED flash is a handy resource in low light, it is also a major battery drainer. Use it only if you must, and use it wisely.

Don't let your phone heat up unnecessarily

Today we are getting phones that have powerful hardware inside a sleek frame. Therefore, heating is a common phenomenon in most of these handsets. Heating takes excess toll on your device's battery life. While you cannot totally control what's going on inside your smartphone, you can at least keep a check on your phone's ambient environment. This means, avoid keeping your smartphone in direct sunlight or even your pockets for that matter (especially during summers).

Don't wait for your phone to discharge completely before charging

Many users think it's wise to drain the battery completely before charging it fresh. Well, it's time to smell coffee in that case. Most phones come with Lithium Ion batteries and in the case of Li-ion batteries, draining them completely before charging them again may lead to lowering your battery life or even damaging them in some cases. It's advisable you keep charging your phone occasionally, instead of waiting for it to drain out completely.

Keep a portable charger at hand

It's always handy to keep an additional power source with you should your phone run out of juice at the most unfortunate of times. Portable chargers or power banks are useful devices and the market is flooded with some really good ones today (at affordable prices too).

Machine Learning

Machine Learning is an application of Artificial Intelligence that provide systems the ability to automatically learn and improve themselves without external programmed.Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.
The best example of Machine Learning can be Self Driving cars,Speech Recognition etc.Self Driving cars are the driverless car.It will be drive automatically.There are many Companies are doing testing on it like Google,Uber etc.

Machine Learning algorithm can be classified into two parts Supervised Machine Learning and UnSupervised Machine Learning.

Supervised Machine Learning

Supervised machine learning algorithms can apply what has been learned in the past to new data using labeled examples to predict future events. Starting from the analysis of a known training dataset, the learning algorithm produces an inferred function to make predictions about the output values. The system is able to provide targets for any new input after sufficient training. The learning algorithm can also compare its output with the correct, intended output and find errors in order to modify the model accordingly.

UnSupervised Machine Learning

unsupervised machine learning algorithms are used when the information used to train is neither classified nor labeled. Unsupervised learning studies how systems can infer a function to describe a hidden structure from unlabeled data. The system doesn’t figure out the right output, but it explores the data and can draw inferences from datasets to describe hidden structures from unlabeled data.

Cryptography

The process of converting plain text to some other text that is only readable not understandable called cryptography.Converted text is called cypher text.Cryptography is not only use for convert plain text to cypher text but also used for authentication purpose whom data is send.
There is only two process is used in cryptography Encryption and Decryption plain text convert in to cypher text called encryption and cypher text convert in to plain text called decryption.

there are two type of Encryption

1)Symmetric Key Encryption

In Symmetric Key Encryption same key is used for Encryption and Decryption.It can be Public Key or can be private key.Public key is the key that is know by all user while Private key is the key that is know by only user that is the owner of the message.

2)Asymmetric key Encryption

In Asymmetric key data encryption different-different key is used for encryption and decryption.If sender encrypt the data using public key of the receiver then receiver can decrypt the message only by use private key of own.And its vise versa is also possible.
