A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory.Q.) What is the largest unsigned binary number that can be accommodated in one word of memory?

Compare 0-, 1-, 2-, and 3-address machines by writing programs to computeX = (A x B + C) / (D − E × B)for each of the four machines. The instructions available for use are as follows: M is a 16-bit memory address, and X, Y, and Z are either 16-bit addresses or 4-bit registers. The0-address machine uses a stack, the 1-address machine uses an accumulator, and the other two have16 registers and instructions operating on all combinations of memory locations and registers. SUB X,Y subtracts Y from X and SUB X, Y, Z subtracts Z from Y and puts the result in X. With 8-bit opcodesand instruction lengths that are multiples of 4 bits, how many bits does each machine need to computeX?
