WebA w-bit word can represent 2^w distinct values. If you had more than 2^w addresses, you'd have addresses that don't correspond to any combination of w bits. If each address corresponds to a byte in memory, then 2^w addresses gives you access to 2^w bytes.

how do you work out how many bits are needed for the opcode?
WebIt represents a number ‘5’. Now consider a sequence of 3 Qubits. [0+1][0+1][0+1]. Depending on our measurement, this sequence can represent any number from 000 (i.e … Web1. 1. (unused) There are four possible combinations of two bits, so with two bits we can represent up to four different values, even though we only need three for the traffic light. Convince yourself that there aren't any more combinations of two bits. Write down all the possible combinations of three bits. small caps and rising rates

WebThe maximum value that could be represented by an 8 bit number is 255, so the range would be 0—255 (256 values). You can work the number of values quickly by calculating 2 n, where n is the number of bits available, for example 2 8 = 256 values. The range of values is from 0 to 2 n – 1, for example 0 to 2 8 – 1 = 0—255. Web23 jul. 2024 · 4. There is a specific case of this problem: current 64-bit x86 CPUs have a 32-bit mode, but with 36-bit address lines. That is called PAE (Physical Address Extension). It is very useful - you can combine the smaller RAM requirement of 32-bit processes, with the 64GB maximal physical RAM of newer, hard-core machines. Web"It took us 8 bits to represent a number that only took 2 digits to represent in the decimal system." 01010101 Uses 8 bits, but I can make it with 7: 1010101. So if we can add 0's in the front, then can't I just say, "It took us 8 bits to represent a number [01010101] that takes a whole 10 digits to represent [0000000085] in the decimal system." small caps and inflation
