Study Notes

The Role of Programs

A program transforms a computer from a mere object into a functional tool.
Computers execute complex tasks through simple operations, not innately.
Basic operations include adding and dividing, which computers perform rapidly and repetitively.

Example of Program Functionality

To compute average speed, a program must:
- Accept input values for distance and time.
- Divide distance by time.
- Store and display the result.
This process illustrates how simple commands form a functional program.

Natural vs. Programming Languages

Language serves as a tool for expressing thoughts; examples include body language and spoken languages.
Computers use a rudimentary form of communication known as machine language.
A computer operates through a fixed set of commands called an instruction list (IL).
Instruction lists differ among computer models and have been developed by humans.

Elements of a Language

Each language, whether natural or machine, comprises:
- Alphabet: A set of symbols for building words (e.g., Latin, Cyrillic).
- Lexis: A collection of words (e.g., "computer" versus "cmoptrue").
- Syntax: Rules governing the construction of valid sentences (correct versus incorrect phrasing).
- Semantics: Rules defining the logical sense of phrases (meaningful versus nonsensical statements).

Machine Language vs. High-Level Language

Machine language represents the foundational alphabet of a computer, known as its mother tongue.
There exists a need for a common language that bridges human and machine communications.
This intermediate language must be more complex than machine language yet simpler than natural language, facilitating programming and execution.
