Study Notes
Computing as a Human Process
- Computing involves a structured human process composed of several key steps: recognizing and clarifying a problem, devising a method, executing the solution, and correcting/revising the solution.
- Humans are essential in the early stages of problem-solving; computers facilitate only the execution and revision stages.
Role of Computers
- Modern computers are electronic devices capable of performing tasks significantly faster than humans, executing millions to billions of operations per second.
- Despite their advanced capabilities, computers are ultimately tools created and programmed by humans, lacking inherent decision-making abilities.
The Complexity of Algorithm Design
- The most complex phase of computing is devising a solving method; this involves human creativity and strategic thinking that computers cannot replicate.
- The process of creating a solution is defined as algorithm development, which is a step-by-step guide that can be executed automatically by a computer.
Importance of Algorithms
- Algorithms are fundamental in both computer science and mathematics, serving as core procedures in programming and problem-solving.
- The term "algorithm" derives from the name of Al-Khwarizmi, a Persian mathematician in the 9th century, highlighting the historical significance of systematic problem-solving methods.
Example of an Algorithm
- A simple example of an algorithm is the process of adding two-digit numbers, which includes:
- Adding the tens place values.
- Adding the ones place values.
- Combining the results from the first two steps to obtain the final answer.
