Dynamic Programming is mainly an optimization over plain recursion. Wherever we see a recursive solution that has repeated calls for same inputs, we can optimize it using Dynamic Programming. The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later.
NP Copmleteness and Approximation Algorithms
In computational complexity theory, a problem is NP-complete when it can be solved by a restricted class of brute force search algorithms and it can be used to simulate any other problem with a similar algorithm. ... If any NP-complete problem has a polynomial time algorithm, all problems in NP do.
ISO-OSI 7-Layer Network Architecture
The International Standards Organization (ISO) developed the Open Systems Interconnection (OSI) model. It divides network communication into seven layers. ... Layers 5-7, called the the upper layers, contain application-level data. Networks operate on one basic principle: "pass it on."

Communication - Case Study
CASE STUDY ON COMMUNICATION Communication is the act of conveying meanings from one entity or group to another through the use of mutually understood signs, symbols, and semiotic rules. The main steps inherent to all communication are: The formation of communicative motivation or reason. Message composition. Message encoding. Message Decoding and Feedback.
