Adigital computer has a memory unit with 48 bits per word. the instruction set consists of 240 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.
a. how many bits are needed for the opcode?
b. how many bits are needed to specify the register? how many bits are left for the address part of the instruction?
c. what is the largest unsigned binary number that can be accommodated in one word of memory?

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
