Programmable read only memory PROM

Data processing. The microprocessor functions according to the program stored in the programmable read-only memory (PROM), a solid-state data-storage device whose contents is virtually indestructible. The main tasks of the 8-bit microprocessor are (a) control of the input multiplexer (b) start and control of the calibration cycle (c) correction of measured values according to the results of the calibration cycle (d) computation of periodic averages (e) calculation of output data (f) output of data and (g) control of peripherals. 

ROM, PROM, EPROM is Read Only Memory, Programmable Read Only Memory and Erasable Programmable Read Only Memory and are used for rapid sourees of information that seldom, or never need to be modified.

A, B, E, F. Since ROM stands for read-only memory and PROM stands for programmable ROM, they automatically are incorrect answers for the question. RAM and SRAM are both monikers of short-term memory (RAM), and therefore have to be erasable to be of any use. EPROM and EEPROMs are both special types of PROMs that are Erasable Programmable (EPROM) and Electronically Erasable and Programmable (EEPROM) and therefore have the ability to be erasable and re-usable.
