What Are the Differences Between 64 bit and 32 bit System?

In the early 1990’s, the processors adapted 32 bit architecture. The data bus was able to handle 32 bit at a time. And then 64 bit processors came to the market, so the data bus has the capacity to handle 64 bit at a time.

Therefore, in order to make use of the capabilities of 64 bit processors, Microsoft released 64 bit operating system versions.

The best part of 64 bit processors is that a 64 bit processor can support both 64 bit and 32 bit operating system. However, a 32 bit processor can only support 32 bit system.

What’s more, there is only 4 GB of RAM for 32 bit system, so if you want to use more RAM, you’d better upgrade 32 bit operating system to 64 bit.
