The differences between 32 bit and 64 bit system

Computer hardware and software can come in 32- or 64-bit versions, the difference between a 32-bit and a 64-bit is the way that it handles memory.

the bit size refers to the memory that it can address a 32-bit system can reference 2^32 power bytes of memory, which equals to about 4 gigabytes, however, a 64-bit system can reference to 2^64  power bytes of memory, which equals to about 16 exabytes which is 4 billion times more memory than a 32-bit.

That number is so huge that it is virtually unlimited because we will never need to use that amount of memory, in a computer or data or a program to run it needs to be loaded into ram first, so the data is stored on the slower hard drive and from the hard drive it is loaded into the faster ram and when it is loaded into ram the CPU can now access the data or run the program.

now in a 32-bit system since the maximum quantity of memory that it can care is four gigabytes it may not be sufficient to hold all the information that the CPU needs to make the computer run as fast as possible and when this happens some of the data must be kept on the slower hard drive to compensate for the low memory, instead of data going from ram to the CPU it must do extra work by going back to the slower hard drive and when this happens it slows down the computer.

But in a 64-bit system, it can store a lot more memory than four gigabytes which means that more data can be stored into the faster ram then on a slower hard drive and because it can store more data into ram the computer can run a lot faster so in a nutshell, therefore, a 64-bit system is faster than a 32-bit system.
