### Questions

Introduction: What is CS?
-------------------------

* Computer science is solving algorithms in order to make a machine
  perform a certain function.
     * What's an algorithm?
     * What does it mean to solve one?
* Solving problems by writing algorithms to solve problems.
* An algorithm is a set of instructions of accomplishing a task.
  [Abraham Lincoln, YouTube Video 2014]
* Design maintenance and advancement of cyberinfrastructure
* To most computer scientists, CS is the study of algorithms (instructions)
  and information (organization)
* Usually, computers follow these instructions
    * Computers are machines that do math and other kinds of instructions
    * Used to be a job title
* This course is about writing clear and unambigious instructions for
  accomplishing a variety of tasks.
