1. Please describe what a data type is.
 
a data type defines what type of data is in the memory space declared for the variable.


2. What is the difference between a strongly typed and loosely typed 
programming language?

Strongly typed when we declare a variable we MUST tell what type of data 
it holds...and if the data is different than the type it throws an error.

int myVa

Loosely typed we don't have to say what type of data and the programming 
language will have it's own ability to determine and morph types as it goes along.

$myVar = "Hello"
$myVar = 1;

3. Is PHP Strongly typed or loosely typed?
Loosely



4. How much memory do you think a BOOLEAN value takes up in memory?

1 or 0; true or false; yes or no;

one bit of memory.
