Computer Science

Hardware

The physical parts of a computer

Software

Instructions and data used by computer

CPU

The component that carries out program instructions

Memory (RAM)

Temporary working space for active programs and data

Storage

Long-term space for saved files and applications

Algorithm

Finite ordered plan for completing a task

Notebook

Document that can contain code, explanations, and saved results

Text cell

Cell used for formatted notes rather than Python instructions

Holds notes, links, predictions, or explanations

Code cell

Cell containing Python instructions that can run

Runtime

Temporary Python process that execute codes and remembers current session state

Output

Visible result produced by running code

NameError

Error that occurs when Python cannot find a requested name

Difference between CPU and RAM

CPU carries out instructions while RAM holds work that is currently in use

Difference between program and algorithm?

Program is a set of instructions while algorithm is an ordered plan for solving a problem

TO KNOW: Saved notebook file and temporary Colab runtime that run its code are different things

TO KNOW: The runtime remembers names created furing the current sesion, but only after their cells have run

TO KNOW: Saving the notebook preserves its cells; it doesn’t preserve every temporary runtime value
