The instruction set or the instruction set architecture (ISA) is the set of basic instructions that a processor understands. The instruction set is a portion of what makes up an architecture. Read More: Define Instruction Set Architecture. What are the main objectives of ISA in computer systems. Two initial types of instruction set architecture are … Read more
Memory Mapped I/O and Isolated I/O are two methods of performing input-output operations between CPU and installed peripherals in the system. Memory Mapped I/O: Memory mapped I/O uses the same address bus to connect both primary memory and memory of hardware devices (registers). Memory and registers of I/O devices gets assigned values, thus when CPU … Read more
Q. What are time sharing and real time systems? What are the differences between time sharing and real time systems? Time-Sharing Systems: Time sharing operating systems are extension of multi-programmed batched operating system and the extension is that here the user can interact with the program running. The CPU scheduling algorithm and allocate small amount … Read more

Time-Sharing Systems: Time sharing operating systems are extension of multi-programmed batched operating system and the extension is that here the user can interact with the program running. The CPU scheduling algorithm and allocate small amount … Read more
Q. What are parallel and multi-programmed batched systems? What are the differences between parallel and multi-programmed batched systems? Multi-programmed Batched Systems: In multi-programmed batched operating systems, the operating system reads jobs from disk drives where a list of jobs are already being stored through card readers. The operating system then pull and store as much … Read more
Q. What are simple batch and multi-programmed batched operating systems? What are differences between simple batch and multi-programmed batched operating systems? Simple Batch Systems: Early computers used to take one job at a time, no input in the middle of the process and also no output either. The jobs were prepared commands for the computer to … Read more
An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence.
Raw materials used in a process to obtain targeted result of goal are called data. In other words, pieces of information which by itself may or may not mean something but useful when connected or used with other pieces of information to form a piece of information that means something, are called data. Data can be of two types
Counter controlled loops are where we know the number of loop executions beforehand. Unlike counter controlled loops, in sentinel controlled loops the number of loop executions in unknow at the beginning and depends on decisions made inside the loop.
