6 Φεβ 2015 · Now applications require more than 4 GB of memory, 64-bit is now widely spread. The addressable value becomes 2^64 (16 Exabytes). So the closest thing that you could say is that a 64-bit CPU can address up to 2^64-1 memory addresses. In practice, it is less than that, since there is no RAM nearly that value.
The article talks about how the processor can reference (or address) the memory. In all modern architectures memory is byte-addressable, which means that every byte-sized memory cell has a number (its address), which the CPU uses to identify that cell.
5 Οκτ 2014 · A key characteristic is the memory address itself will be 32bits or 64bits, and hence could access upto \$2^{32}\text{ and }2^{64}\$ units of memory, bytes. A simple view is a 32bit bit processor typically operates on 32bits of data, and a 64bit CPU acts on 64 bit data.
Hence, a processor with 64-bit memory addresses can directly access 2 64 bytes (16 exabytes or EB) of byte-addressable memory. With no further qualification, a 64-bit computer architecture generally has integer and addressing registers that are 64 bits wide, allowing direct
On google they just explain that a 64-bit address can represent $2^{64}$ different values and thus it equates to the processor being able to process $2^{64}$ values (or memory locations) at a single time, though I am interested in as much detail as possible regarding how exactly that looks like.
The most commonly used units of data storage capacity are the bit, the capacity of a system that has only two states, and the byte (or octet), which is equivalent to eight bits.
digital representation means that everything is represented by numbers only. the usual sequence: something (sound, pictures, text, instructions, ...) is converted into numbers by some mechanism. the numbers can be stored, retrieved, processed, transmitted.
