In cryptography, confusion and diffusion are two properties of the operation of a secure cipher which were identified by Claude Elwood Shannon in his 1949 paper, Communication Theory Of Secrecy Systems. From that day till today, these two remains to be the guiding principles for the design of cryptographic algorithm. In simple terms, diffusion spreads … Read more
What Is Unit Testing? Unit testing is a software development process in which the smallest testable parts of an application known as units are individually and independently scrutinized for proper operation. This process can be done manually but it is usually automated. Unit testing involves only those characteristics that are vital to the performance of … Read more
In programming, control structures are generally important in shaping the flow of code execution. Among the most critical decision-making constructs are “if-else” and “switch case” statements. These two constructs are applied to execute specific blocks of code based on different conditions or multiple possibilities. However, despite their shared objective of control flow, they differ in … Read more

Flowcharts and algorithms are both tools used in computer programming and problem-solving to visually represent the logical steps and processes of a task. However, they serve different purposes and have different characteristics. Get to understand the difference between Flowchart and algorithm. The basis of comparison includes: complexity, geometrical diagrams, and scope of usage, use, users, … Read more
What Is Symmetric Encryption? Symmetric encryption is a type of encryption whereby only one cryptographic key (secrete key) is used to both encrypt and decrypt electronic information. The entities communicating through symmetric encryption must exchange the key so that it can be used in the decryption process. When a server and client are in need … Read more

Key Difference Description Wi-Fi is an acronym for Wireless Fidelity. It is a wireless networking technology that … Read more
What is a Relay? Relays are switches that open and close circuits electromechanically or electronically. Relays are the primary protection as well as switching devices in most of the control processes or equipments. All relays respond to one or more electrical quantities like voltage or current such that they open or close contacts or circuits. … Read more
