    Preamble or Start Field When computers are connected to a physical medium, there must be a way they can grab the attention of other computers to broadcast the message, "Here comes a frame!" Various technologies have different ways of doing this process, but all frames, regardless of technology, have a beginning signaling sequence of bytes. 10101010…….10101010 Depending up frame format: Preamble = 7 bytes, Start or Start of Frame...

    Analysis and design of algorithms - chapter 8: Approximation Algorithms

    Many problems of practical significance are NP-complete but are too important to abandon merely because obtaining an optimal solution is intractable. If a problem is NP-complete, we are unlikely to find a polynomial time algorithm for solving it exactly, but it may still be possible to find near-optimal solution in polynomial time. In practice, near-optimality is often good enough. An algorithm that returns near-optimal solutions is called...
