Chapter 2
  1. Back Tracking
    1. An algorithmic approach to a problem where partial solutions to a large problem are incrementally built up as a pathway to follow, and then, if the pathway fails at some point, the partial solutions are abandoned and the search begins again at the last potentially succesful point.
      1. Well-known strategy for solving logic problems
      2. Data Mining
        1. The practice of examining large pre-existing databases in order to generate new information.
          1. Useful way to search for relationships
            1. A process for trawling through lots of data that probably comes from many sources
            2. Pipelining
              1. Is a situation where the output of one process is the input to another
                1. Useful in RISC processors
                2. Abstraction
                  1. A concept of reality that commonly makes use of symbols to represent components of a problem so that the human mind or a computing agent can process the problem
                    1. Is about teasing out what does and what does not matter in a scenario
                    2. Caching
                      1. In caching, data that is input might be stored in RAM in case it is needed again before the process is shut down
                        1. If it is required, it does not need to be read in again from disk, thereby giving a faster responce time
