In computer architecture, 32-bit integers, memory addresses, or other data units are those that are at most 32 bits (4 octets) wide. Also, 32-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 32-bit is also a term given to a generation of microcomputers in which 32-bit microprocessors are the norm.
Range for storing integers
A 32-bit register can store 232 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (232 - 1) for representation as an (unsigned) binary number, and -2,147,483,648 (-231) through 2,147,483,647 (231 - 1) for representation as Two's complement.
One important consequence is that a processor with 32-bit memory addresses can directly access at most 4 GiB of byte-addressable memory (though in practice the limit may be lower).

Boom
by: P.O.D.Push up
Haha, I never knew that a kid like me
Could take his mic around the world
(World)
Flash the big S.D.
And rock the masses
From Madrid to Calabasas
Tijuana, Mexico
Bootleg demos in Tokyo
Say they know me though
'Cause I'll be puttin' in work
Commit my life to rebirth
Well respected, 'cause that's my word
And I'm sure you heard
(Heard)
'Bout a new sound goin' 'round
She might have left my hood
But she was born in my town
You didn't know, thought we was new on the scene
(Well it's alright, it's alright)
I know you know, I see you smilin' at me
(Well it's alright, it's alright)
Boom!
Here comes the
Boom!
Ready or not?
Here comes the boys from the South
Boom!

Boom!
Ready or not?
How you like me now?, I say
We rep the South
So what you talkin' 'bout?
I'm not runnin' off my mouth
I know this without a doubt
'Cause if you know these streets
Then these streets know you
An' when it's time to handle business
Then you know what to do
(What to do)
Me and my crew
We stay true, old skool or new
Many were called
But the chosen are few
(We are few)
We rise to the top
What you want, just in case you forgot
Rush the stage, grab my mic
Show me what you got?
You didn't know, thought we was new on the scene
(Well it's alright, it's alright)
I know you know, I see you smiling at me
(Well it's alright, it's alright)
