Author claims you get unlimited memory addressing on 64-bit, is that right? I thought it was just really big.

Author claims you get unlimited memory addressing on 64-bit, is that right? I thought it was just really big.
- duskwuff 17y agoIt's 256 TB on current hardware, and has the ability to grow up to 16 EB... it's not quite unlimited, but it might as well be.
- Psyonic 17y agoTechnically, yes, but in this case really big is REALLY BIG. I don't want to be the next 640k is enough for anybody guy, but a 64-bit address space is enough for anybody.
- ncarlson 17y agoDon't worry, you won't be that 64k guy. 64 bit gives the possibility of 2^64 bytes of addressable memory. That's over 18 exabytes. The entire digital content of the web is only estimated at about 90 petabytes. If we go to 2^128 or 2^256, we start moving into numbers really large numbers. I and I really large. The number of atoms in our galaxy in near 2^220.
