What is 64-bit?

October 1, 2013

Have you noticed that the technical specifications for computing technology always seem to be numbers that double after a while? This has particularly been true of numbers with the word “bit” after them. 8-bit. 16-bit. 32-bit. And now, yes, 64-bit is the latest buzz. But if you’re a normal person (not a computer person), what does this mean?

One of my colleagues (Ed) sent me a link to this short article that loosely explains what 64-bit means to you, the normal person: What the iPhone 5s ’64-bit’ processor means, in plain English. I particularly like the library and book analogy. While I see from the comments that the true technophiles object to the explanation, I’m still going to call it good enough for the normal person. By passing it along, I hope it’s helpful to you or someone you know.
