Without all the mumbo jumbo, in a nutshell;
Computers store real number using an equation (sum) alot like scientific notation, except without the decimals, basically like this:
378 X 10 4
that 4 is suppose to be tiny, but im hoping y'all know what I mean. This is called floating point, not scientific notation.
the 378 bit would be called the exponent
and the 4 would be called Mantissa
or the other way around, im not sure. The bold words will be key words you'll probably need.

What is the set of numbers including all irrational and rational numbers?
real numbers
True or false irrational numbers are not real numbers?
False. Irrational numbers are real numbers.
What are the two subsets of the real numbers that form the set of real numbers?
rational numbers and irrational numbers
Which of these sets of numbers is not a subset of the real numbers irrational integer rational and imaginary?
Imaginary numbers are not a subset of the real numbers; imaginary means not real.
What kind of numbers belongs to the family of real numbers?
Numbers that include real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.

£1.25
How does a computer store pictures in computer memory?
As coded numbers, just like it stores anything else.

They're real!
Where can you buy an SD Card Reader?
Any photo store or computer equipment store in real life or on line.
Real numbers are encoded using the what technique in computer?
I believe it is the floating-point.
How and why are real numbers more difficult to represent and process than integers?
There are more real numbers than integers. The set of integers is countably infinite, of magnitude aleph-zero. The set of real numbers is uncountably infinite (specifically, aleph-one).A computer can't really represent real numbers (that would require an infinite amount of memory), rather, it uses an approximation.There are more real numbers than integers.

Is cyberspace real?
Cyberspace is a conceptual space made of numbers--- all computer data is reduced to numbers. So cyberspace is real, but nothing we can touch, taste, smell, or hold.
What devices can store names addresses and phone numbers?
Cell phone Computer Ipod (If you have the app) PDA
Can numbers be stored accurately in a computer?
Well, any computer ever made has some sort of limit to how much it can store. For example, the number Pi has an infinite number of digits, so no computer could ever store Pi accurately because it's infinite in size. But, for just about any practical purpose, numbers can be stored accurately *enough*. It all depends on what you need those numbers for -- store only as much as you need to do the task at hand.
How are numbers used to describe real-world situations?
Can you find a real-world situation that numbers don't describe? From the numbers on your alarm clock to the numbers on your house, to the bus you ride to work, to the numbers on the phone as you order takeout, to the prices at the grocery store, to your bar tab, it's all numbers.
What are the advantages of computer mapping?
the advantages of computer mapping are: store,process and display map data. Also must be written in numbers from 0-1.
