It refers about the architecture of the operating system 32 bits only recognize 3.8 GB of RAM memory and 64 Can recognize more than 4 GB Of RAM memory, Talking About Windows 7
64 or 32 although the 64 will be able to run 32 bit programs.
There are different versions of Vista as well as 32-bit and 64-bit for each. To switch from 32-bit to 64-bit you would have to make sure that you have 64-bit compatible hardware and would have to purchase a 64-bit version of Vista.
A 32 bit processor has 32 bit wide data bus while a 64 bit has 64 bit wide data bus. Address bus may or may not be 32 bit or 64 bit wide in the respective processors. To fully utilise the 64 bit data bus the programs must be written in such a way that they can use 64 bit wide data bus. A 64 bit processor can also act as 32 bit.
You mean 32-bit and 64-bit, not 32 byte and 64 byte. A byte is an aggregate of (usually) 8 bits. 32-bit programs will execute in a 64-bit environment without any modification. 64-bit programs can also execute in a 32-bit environment, but this requires emulation through a 64-bit virtual machine.
Q6600 is a 64 bit processor, but it can execute in 16 and 32 bit modes.
32 bit and 64 bit are 2 types of versions of software available. 64 bit software are more secure than 32 bit.
if i have a 32 bit on a 64 bit prosseser witch game bit do i install
64 bit OSes use special set of instructions as well as 64 bit memory space which is in principle is not supported by 32 bit processors.
Most 64-bit operating systems contain a 32-bit translation layer. Installing a 32-bit program is no different than installing a 64-bit one.
In simple terms, 32-bit operating systems can only be able to run on 32-bit CPUs and 32-bit apps, but a 64-bit operating system can be able to run both 32-bit and 64-bit CPUs and apps.
32 bit means the number of address lines are 32. it can point to 2^32(2 to the power of 32) address locations in memory. the 32 bit refers that a 32 bit of information can be executed simultaneously that is copying or reading writing takes 32 bit of data at a time. the system bus contains 32 lines of wires to hold the data. while the 64 bit represents the number of address lines are 64 and data can handle 64 bit at once same as 32 bit. all present using PCs are 64 bit.
32 bit applications will work on 64-bit but they will not run as efficient as 64-bit application. the reason for this is the 64-bit uses the memory better than a 32-bit. this is why a 32-bit can only use up to 3 gigs of ram and a 64-bit can use 16 gigs +
