We also know that, internally, a computer is a binary machine; thus the data and the program instructions must be stored in binary form. Characters are represented in a binary code. Numbers are stored as binary numbers, with each bits positional value significant. A computer's main memory is divided into bytes, words or both( depending on the system), and each of these basic storage units is assigned an address. Using this address, the processor can read or write

Reading comprehension Multiprocessing is the use of two or more central processing units linked together to optimize the processing of data In a multiprocessing environment, more than one instruction can be executed by the CPUs at the same time. This is in contrast to multiprogramming, where one CPU can process different instructions from one or more programs concurrently by interleaving them. With multiprocessing, there is actually more than one CPU; hence more than one instruction can be executed simultaneously A typical application of multiprocessing is the use of a minicomputer to handle scheduling, formatting of data, editing, and summary totals so that the main CPU or mainframe can be used for high-priority or more complex tasks Sometimes a smaller CPU such as a minicomputer handles input/output operations from a variety of terminals. In this way, the main CPU needs to access only one unit-the minicomputer- ather than each of the numerous terminals. For such applications, the minicomputer is referred to as a front-end processor. The front-end processor can establish priorities for each of the terminals, queue the terminal inquiries if the mainframe is,, and maintain controls minicomputers are used with increasing frequency in a multiprocessing environment to relieve some of the load of a mainframe and to handle input/output scheduling and data entry from remote terminals Choose the correct answers for the following brackets
