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).

Technical Interview Questions asked in Top Companies

Q.1:- How will you implement Linked list with 1 million nodes? How will you access 999999th node?

Q.2:- Clone a linked list with next and random pointer.

Q.3:-Serialise and Deserialise a linked list with next and random pointer.

Q.4:-Given two sorted array(with repetitive elements) find kth minimum number from both array.

Q.5:-Given two linked list both represent a number.Create a linked list that create its sum.

Q.6:-Given a binary search tree, print the path which has sum equal to k and has minimum hopes.i.e. if there are multiple paths with the sum equal to k then print the path with minimum number of nodes.

Q.7:-Given an array, arrange the elements such that the number formed by concatenating the elements is highest. 
E.g.: input = [9, 93, 24, 6], the output should be: [9,93,6,24]. This is because if you concatenate all the numbers, 993624 is the highest number that can be formed.

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.
