TCP (Transmission Control Protocol) is a protocol used at Transport layer for providing reliable connectivity to various other protocols for example FTP, Telnet, BGP etc. It establishes a connection also know as TCP 3-Way Handshake before sending any data and everything that it sends is acknowledged by the receiver. In this lesson we will go […]

A hashing algorithm is loosely defined as a one-way algorithm that produces a fixed-length output no matter what size the input variable is. Hashing algorithms are used for integrity assurance. They are based on some type of one-way hashing function. This blog post helps us understanding How Hashing Algorithms work? Consider the following analogy of […]
