•Processors are typically 64-bit, which can process faster than 32-bit processors
• 32-bit processor –4 Gigabytes of RAM
•64-bit processor –1 Terabyte of RAM
•A processor can only work on a single process / thread at a time
•Time slicing enables multiple threads and applications to be running at the same time
•A multicore processor enables multiple threads / application instructions to be worked on at the same time
