Study Notes

Computer Functionality

Computers are general-purpose machines executing programs.
Programs dictate computer behavior (e.g., word processing, online shopping).
Computers process data based on program instructions achieving specific goals.
A computer is also called a universal machine.

Program Design and Development

Creating programs involves designing steps to achieve a task (e.g., product listing in an online store).
Steps are translated into computer instructions.
Computer programming is challenging but rewarding and fun.
Programmers are in high demand.

Programmer vs. Computer Scientist

Programmers focus on practical applications, crafting programs for tasks.
Computer scientists study information processing theories.
Computer scientists design hardware and software, aiming for efficiency.
Computer science knowledge is beneficial for programmers needing to understand the machine they control.

Limitations of Computers

Computers can't perform every task humans can due to complexity or resource requirements.
Computer capabilities are limited by available programs.
The intelligence of a computer is determined by the written program.
