Solution

Yes,a computer need data registers. As these are general purpose data registers as being discrete memory locations within the CPU used to hold temporary data and instructions.And are also required to store any transient data required in the program.For example, when a program is interrupted its state, ie: the value of the registers such as the program counter, instruction register or memory address register - may be saved into the general purpose registers, ready for recall when the program is ready to start again.
