Q) What is NAT?

ANSWER:  The abbreviation for network address translation (NAT) is network address translation. Remapping one IP address space to another, entails changing the IP headers of packets being transmitted across a traffic routing device.Q) What is piggybacking?ANSWER:  In two-way communication, the receiver sends a control frame, or ACK, to the sender after receiving data packets. The receiver, on the other hand, waits until its network layer has received the subsequent data packet before sending the acknowledgment. The arriving data frame is subsequently supplemented with the ACK. The process of piggybacking involves delaying the ACK and attaching it to the subsequent outgoing data frame.Q) What exactly is a database schema? What are the different kinds?ANSWER:  A “database schema” is a blueprint for creating a database that outlines the way data is structured (divided into database tables in the case of relational databases). An official definition of a database schema is a set of formulas (sentences) that impose integrity requirements on a database.

  • The three different types of the schema are physical schema, logical schema, and view schema.
  • The physical schema explains how a database’s physical level characterizes the data found in storage blocks.
  • Data can be described as specific types of data records that are kept in data structures; programmers and database managers work at the level of the logical schema, which hides fundamental specifics like data structure implementation (available at the physical level).
  • The design of a database at the view level is known as the view schema. This phrase describes how end users communicate with database management systems.

Q) Briefly Describe the RSA Algorithm

ANSWER: The data transit is secured using the asymmetric cryptography technique RSA. This method uses a public key for encryption while keeping the decryption key safe or hidden. The encryption key is created using two enormous prime numbers and is then made public along with an auxiliary value. Anyone can encrypt data with this public key, but only those who are prime number aware can decrypt it. However, because it is thought to be sluggish, this method is not generally used to encrypt data.

int x = 5, y = 15;

   // Code to swap the values of x and y
   x = x + y; // x now becomes 20
   y = x - y; // y becomes 5
   x = x - y; // x becomes 15


int x = 5, y = 15;

   // Code to swap the values of x and y
   x = x * y; // x now becomes 75
   y = x / y; // y becomes 5
   x = x / y; // x becomes 15

This can also be achieved using bitwise operations.

int x = 5, y = 15;

     // Code to swap the values of x and y
     x = x ^ y; // x now becomes 20
     y = x ^ y; // y becomes 5
     x = x ^ y; // x becomes 15

Q) What do you mean by SQL Correlated Subqueries?
