Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When building a computer with a 32 bit processor, which of the following is the MAXIMUM amount of memory supported?
A
1 GB
B
2 GB
C
4 GB
D
8 GB
Explanation: 

Detailed explanation-1: -A 32bit processor can address at most 2^32 individual bytes of memory (about 4GB), but having 1GB of memory would make 1*1024*1024*1024 addressable bytesof memory (though you would probably still have a 2^32 virtual address space).

Detailed explanation-2: -In terms of Random Access Memory, 32-bit architectures can address 4GB of memory, maximum.

Detailed explanation-3: -What are the RAM limits of a 32-bit operating system? All 32-bit operating systems have a 4GB RAM limit.

Detailed explanation-4: -Every byte of RAM requires its own address, and the processor limits the length of those addresses. A 32-bit processor uses addresses that are 32 bits long. There are only 4, 294, 967, 296, or 4GB, possible 32-bit addresses.

Detailed explanation-5: -PAE mode enables processors to use more than 4 GB of memory.
