It is interesting to note that the microprocessor had existed for only 10 years prior to the creation of the PC! Intel invented the microprocessor in 1971; the PC was created by IBM in 1981. Now more than 20 years later, we are still using systems based more or less on the design of...
In boilers – Thermal Power Plants PLC Programming When using a PLC, it’s important to design and implement concepts based on your particular use case. To do this, we first need to learn more about the specifics of PLC programming. A PLC program consists of a set of instructions either ...
It is a 16 bit special function register in the 8085microprocessor. It keeps track of the thenext memory addressof the instruction that is to be executed once the execution of the current instruction is completed.In other words, it holds the address of the memory locati...
can be held in a few registers. This additional information is relocated to special memory circuits.Memoryis composed of dense arrays of parallel circuits that use their voltage states to store information. Memory also stores the temporary sequence of instructions, or program, for the microprocessor...
Computer memory, device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. Computers represent information in binary code, written as sequences of 0s and 1s. Eac
