If a machine . computer works –introduce you to assembly-level programming –prepare you for future courses. Usually volatile memory. . Main memory is as vital as the processor chip to a computer system. The major hardware components of a computer system are: Processor Main memory Secondary memory Input devices Output devices For typical desktop computers, the processor, main memory, secondary memory, power supply, and supporting hardware are housed in a metal case. A. The Memory Hierarchy To this point in our study of systems, we have relied on a simple model of a computer system as a CPU that executes instructions and a memory system that holds instructions and data for the CPU. Then we’ll look at the various types of memory, speeds, and packaging of the chips and memory modules you can buy and install. A computer system requires hardware, software and a user to fully function. With processor performance stagnating, it is also time to consider new programming models that move some application computations into the memory system. endobj • All contents are erased when the system's power is turned off or interrupted. @@@@@@@@@@@@�� 8^" �� �� ?
