Solution(By Examveda Team)
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. CP/M was displaced by DOS soon after the 1981 introduction of the IBM PC.This Question Belongs to Computer Fundamentals >> Operating System
