Fourth Generation vs Fifth Generation Programming Languages (4GL vs 5GL) A programming language is a non-natural language used to present the computations that a machine can perform. Very first programming languages (often called 1st generation languages or 1GL) were mere machine code consisting of 1’s and 0’s. Programming languages have evolved tremendously over the past […]

Randomized vs Recursive Algorithm Randomized algorithms incorporate a sense of randomness in its logic by making random choices during the execution of the algorithm. Due to this randomness, the behavior of the algorithm can change even for a fixed input. For many problems, randomized algorithms provide the most simplest and efficient solutions. Recursive algorithms are […]

Stream Cipher vs Block Cipher | State Cipher vs Block Cipher In cryptography, Stream ciphers and Block ciphers are two encryption/decryption algorithms that belong to the family of symmetric key ciphers. Typically a cipher takes a plain-text as input and produces a ciphertext as output. Block ciphers encrypts fixed-length block of bits using an unvarying […]
