WebReads the current value of the processor’s time-stamp counter (a 64-bit MSR) into the EDX:EAX registers. The EDX register is loaded with the high-order 32 bits of the MSR and the EAX register is loaded with the low-order 32 bits. (On processors that support the Intel 64 architecture, the high-order 32 bits of each of RAX and RDX are cleared.) WebAssembler means the program that translates your source code. A more correct term is "assembly language". Explain the difference between big endian and little endian. Little endian places the least significant bit in position 0, on the right side of the number. Big endian does the opposite.
