Many times you have heard that someone has a 32-bit window & someone has a 64-bit window, most of us have used a 32-bit window. have seen 32 bit OS being referred to x 86.
Now the question is why 32 bit is denoted as x86? The x86 designation comes from an old Intel 16 bit processor standard. The 16-bit chips in early PCs used the 8086 architecture. The x86 comes from a line of 16-bit processors, named after the Intel 8086, like the 8086, 8088, 80286, 80386, 80486, Pentium, Celeron, Core, and so on.80386 was a 32-bit CPU and x86 usually refers to its descendants. When 64-bit processors were introduced, they were referred to as x64 to distinguish them from the older processor lines.
