In computer architecture, 64-bit integers, memory addresses, or other data units are those that are at most 64 bits (8 octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 64-bit is also a term given to a generation of computers in which 64-bit processors are the norm.
64-bit is a word size that defines certain classes of computer architecture, buses, memory and CPUs, and by extension the software that runs on them. 64-bit CPUs have existed in supercomputers since the 1970s (Cray-1, 1975) and in RISC-based workstations and servers since the early 1990s. In 2003 they were introduced to the (previously 32-bit) mainstream personal computer arena in the form of the x86-64 and 64-bit PowerPC processor architectures.
A 64-bit register can store 264 = 18446744073709551616 different values, a number in excess of 18 quintillion. Hence, a processor with 64-bit memory addresses can directly access 264 bytes of byte-addressable memory.
A bit (a contraction of binary digit) is the basic capacity of information in computing and telecommunications; a bit represents either 1 or 0 (one or zero) only. The representation may be implemented, in a variety of systems, by means of a two state device.
In computing, a bit can be defined as a variable or computed quantity that can have only two possible values. These two values are often interpreted as binary digits and are usually denoted by the numerical digits 0 and 1. The two values can also be interpreted as logical values (true/false, yes/no), algebraic signs (+/−), activation states (on/off), or any other two-valued attribute. The correspondence between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. The length of a binary number may be referred to as its "bit-length."
In information theory, one bit is typically defined as the uncertainty of a binary random variable that is 0 or 1 with equal probability, or the information that is gained when the value of such a variable becomes known.
If it wasn't for you!
Do I believe in the resurrection of Christ?
And did His death bring forth new life?
And did He raise up and bring back Lazurus from the
grave?
Is there supposed to be a Second Coming?
Am I wrong because I'm wondering
Why the fallen Babylon is up and alive today?
And do I really believe in the Mark of the Beast
Cause he's still dwelling up in my streets
Strapped and ready to fight this war
And he's got more guns than you and me
And most people don't wanna believe
That they still prejudice, simply because we poor
Do I believe that Mother Teresa was an angel on this
earth
And thou shall love thy neighbor, even if he acts like
you?
Do believe in Heaven and Hell, shoot, hell yeah I do
Cause we alive today, and my crew is living proof
If it wasn't for you!
None of this would ever mean a thing
If it wasn't for you!
Tell me why else would I believe
What I believe
Do I believe that the Rider of the White Horse
Is coming back for the righteous?
And the Morning Star keeps getting brighter every day?
Is there such a thing as good and evil
Still division amongst the people?
And we're not all created equally, just because you say
Do I believe in the Trinity?
And will I live eternally?
Even though I'm not quite the saint that you claim to
Did Dr. Martin Luther have a dream?
Was Haile Sillasi a king?
And is it okay to sometimes feel a little bit confused?
Will Armagedon ever come?
I'm not perfect, just forgiven
And I might just push back the next time you shove
Do I believe in One God, one aim and destiny?
Just don't forget your First Love
That's what my mom used to tell me
If it wasn't for you!
None of this would ever mean a thing
If it wasn't for you!
Tell me why else would I believe
(What I believe)
If it wasn't for you!
Then none of this is for nothing
It's all for nothing!
It's all for nothing!
It's all for nothing!
If it wasn't for you!
None of this would ever mean a thing
If it wasn't for you!
Tell me why else would I believe
(What I believe)
If it wasn't for you!
None of this would ever mean a thing
(What I believe)
If it wasn't for you
(Would I believe)
If it wasn't for you
