VPN
Introduction of VPN VPN stands for ‘Virtual Private Network’. The concept of a Virtual Private Network (VPN) has its roots in the 1990s when businesses began to realize the need for secure remote access to their internal networks. In 1996, Microsoft developed the PPTP (Point-to-Point Tunneling Protocol) protocol, which was Read more…

Cryptography
Introduction of Cryptography Cryptography has been used for centuries, from ancient civilizations that used secret codes and ciphers to protect their messages, to modern-day applications that rely on advanced mathematical algorithms and techniques. With the increasing reliance on digital communication and the rapid growth of the internet, cryptography has become more Read more…

Types of Processor/Microprocessor
History The term “Microprocessor” was first used when the Viatron system 21 small Computer System was announced in 1968. Since the 1970s, the use of microprocessors has consequently increased, cutting across several use cases. Microprocessors were initially called “Microcomputer on a chip” until 1972. The microprocessor was invented by a Read more…

Pseudocode
Definition Pseudo-code is a compact and informal high-level description of a computer programming algorithm that uses the structural conventions of some programming language. Pseudocode is a kind of structured English for describing algorithms in an easily readable and modular form. This helps in describing how the system will solve the given problem. Read more…

Notations for complexity
(A) Asymptotic Notations (n→∞): Asymptotic notations are used to express the running time of an algorithm in terms of function, whose domain is the set of natural numbers N={1,2,3,…..}. Such notations are convenient for describing the worst case running time function T(n). Asymptotic notation gives the rate of growth, i.e. Read more…
