Key points:

• Definition of Algorithms: Step-by-step procedures for solving computational problems.

• Difference Between Algorithms and Programs: Algorithms are created during the design phase, while programs are written during the implementation phase.

• Domain Knowledge: The person designing an algorithm should have domain-specific knowledge, while programmers implement it.

• Independence of Algorithms: Algorithms are hardware and software-independent, unlike programs that depend on the environment they run on.

• Efficiency: Algorithms are analyzed for efficiency in terms of time and space, while programs are tested by running them.

• Programming Language: Although algorithms can be written in plain English or mathematical notation.
