## Answers

### Answer by Hitesh Vohra

- A **64-bit** computer may access 264 distinct [**memory**](https://answers.mindstick.com/qa/97186/how-to-know-it-s-time-for-a-memory-upgrade) addresses, or 18 quadrillion bytes of RAM. In other words, it can easily handle any amount of memory larger than 4 GB.
- Because it can handle more data at once, a 64-bit CPU is more capable than a 32-bit processor. A 64-bit processor may hold more computational data, including memory addresses, than a 32-bit processor, allowing it to access over 4 billion times the physical memory.
- ECC memory is frequently referred to as 72 bit memory. Error Correction Check has an additional 8 bits. Non-ECC memory is 64 bits. 168 pin DIMMs are commonly found in 72 bit or 64 bit configurations.
