Answer:

The 8031 chip is a ROMless version of the 8051. In other words, it is exactly like any member of the 8051 family such as the 8751 or 89C51 as far as executing the instructions and features are concerned, but it has no on-chip ROM. Therefore, to make the 8031 execute 8051 code, it must be connected to external ROM memory containing the program code

Therefore, in many systems where the on-chip ROM of the 8051 is not sufficient, the use of an 8031 is ideal since it allows the program size to be as large as 64K bytes.
