Study Notes
Logarithms and Early Computing
- John Napier is credited with inventing logarithms, which led to the invention of the slide rule.
- Charles Babbage's Analytical Engine was designed to perform any calculation that could be expressed in an algorithm.
Problem Solving
- A computer is a device that can perform calculations and process information automatically.
- Charles Babbage invented the Difference Engine to ease calculation.
- The first generation of electronic computers used vacuum tubes.
- Transistors replaced vacuum tubes in the second generation of computers.
- The integrated circuit, which combines transistors, resistors, and capacitors into a single 'chip', was developed in the third generation of computers.
- ENIAC, developed in 1946, was the first fully electronic digital computer built in the U.S.
- The development of microprocessors in the 1970s marked the beginning of the fourth generation of electronic computers.
- The IBM-Intel-Microsoft joint venture in 1981 produced the IBM PC.
Steps in Problem Solving
- The first step in solving a problem is to understand the problem.
- Problem solving is the process of finding a solution to a problem.
- There are five steps involved in solving a problem: understand the problem, plan a solution, carry out the plan, check the result, and refine the solution.
- A flowchart or pseudocode is used to plan a solution.
- Strategies for problem solving include divide and conquer, trial and error, and working backward.
- Divide and conquer involves breaking up large problems into smaller, more manageable units.
- Trial and error is the most simple and basic problem-solving strategy that involves experimenting with possible solutions.
- Working backward requires undoing some of the key actions in the problem to solve it.
- Reasoning is a more advanced way to solve a complicated problem by recognizing patterns within the domain.
