Difference between #define and const

• Both are used to define constants

• #define is a preprocessor directive and replaces all occurrences of the defined identifier with the given value

• const is a keyword and creates a read-only variable

• const is type-safe and has better scope control than #define

• Example: #define PI 3.14 vs const float PI = 3.14;

• Example: #define MAX(a,b) ((a)>(b)?(a):(b)) vs const int MAX = (a)>(b)?(a):(b);

OSI layers are a conceptual model that describes the communication functions of a network.

• Layer 1 (Physical): Transmits raw data bits over a physical medium

• Layer 2 (Data Link): Provides error-free transfer of data frames between nodes

• Layer 3 (Network): Routes data packets between networks

• Layer 4 (Transport): Provides reliable data transfer between end systems

• Layer 5 (Session): Establishes, manages, and terminates sessi...read more

One cryptographic technique is RSA, which uses public and private keys to encrypt and decrypt data.

• RSA stands for Rivest-Shamir-Adleman, named after its creators.

• It is a widely used asymmetric encryption algorithm.

• RSA uses a public key to encrypt data and a private key to decrypt it.

• The security of RSA is based on the difficulty of factoring large prime numbers.

• RSA is used in various applications such as secure communi

Public and private keys are used for secure communication and encryption.

• Public key is used for encryption and can be shared with anyone.

• Private key is used for decryption and should be kept secret.

• They are used in various security protocols like SSL, SSH, and PGP.

• Example: When you visit a website with SSL, your browser uses the website's public key to encrypt data, which can only be decrypted by the website's private ...read more

B-Tree is a self-balancing tree data structure with multiple child nodes and is used for efficient disk access.

• B-Tree has a root node, internal nodes, and leaf nodes.

• Each node can have multiple child nodes.

• The number of child nodes is fixed for a given B-Tree.

• B-Tree is self-balancing, which means that the height of the tree is minimized.

• B-Tree is used for efficient disk access as it reduces the number of disk accesses ...read more
