Why are interrupt required?
Interrupts are required in order to get the attention of the CPU. A CPU typically has two interrupt lines. One is the nonmaskable interrupt line (NMI). That is used in the case of critical errors, since this interrupt cannot be ignored. The other one is the regular interrupt line. That is used by hardware devices and certain software to get the attention of the CPU. When you move a mouse, for instance, that creates both a hardware and software interrupt. So the CPU would then process the mouse driver code and move the cursor, then get back to what it was doing.
What are interrupts initiated by instructions called?
Those would be software interrupts. Interrupts initiated by the hardware would be hardware interrupts. While the socket a mouse is plugged into would use a hardware interrupt, a mouse driver would use a software interrupt.

When the mouse initiates a hardware interrupt to the CPU how does the CPU know?
The CPU does not "know" it is not a thinking being. What happens is that the interrupt flag ( a binary true or false register) is detected by the operating system which is being executed by the CPU and the code of the operating system runs a routine in response.
