JavaScript and Dynamic HTML: Create Interactive Web Pages
Chapter 6
Dynamic Documents with JavaScript
Introduction
- A dynamic HTML document is one whose tag attributes, tag contents, or element style properties can be changed after the document has been and is still being displayed by the browser.
- Dynamic, interactive, animated.
- Many previous w3schools.com examples were dynamic, changing the content of elements, CSS style properties, etc.
- Changes to documents can occur when they are requested by user interactions, at regular timed intervals, or when browser events

Microprocessor vs. Microcontroller
A microprocessor is a CPU on a single chip.
A microcontroller includes a microprocessor, supporting circuitry, memory, and peripheral I/O components in a single chip.

Password Security Best Practices
A password should be difficult for a computer program to guess.
- Make it long: The longer a password is, the less likely it is that a computer program would be able to guess it in a reasonable amount of time. You should try to create passwords that include ten or more characters.
- Make it complex: In addition to length, the complexity of a password also helps prevent automatic ‘password cracking’ software from guessing the right combination of characters.
- Make it practical:
Essential Computer Components and Programming Languages
Major Components of a Computer
All general-purpose computers require the following hardware components:
- Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions.
- Memory: Enables a computer to store, at least temporarily, data and programs.
- Input Device: Usually a keyboard or mouse, used to read data and programs into the computer.
- Output Device: A display screen, printer, etc., that lets you see what the computer has accomplished.
- Mass Storage Device:
Parallax Propeller C Code Examples
Index Array Variables
This code demonstrates how to initialize and iterate through an integer array in C for the Parallax Propeller microcontroller.
int main() // Main function
{
int p[] = {1, 2, 3, 5, 7, 11}; // Initialize the array
for(int i = 0; i < 6; i++) // Count i from 0 to 5
{
print("p[%d] = %d\n", i, p[i]); // Display array element & value
pause(500); // 1/2 second pause
}
}
Scan to Integer
This example shows how to prompt a user for input, scan an integer value, and
