Axia College Material Appendix H Memory Powerful central processing units (CPUs) demand large amounts of data‚ and they need that data fast. Otherwise‚ CPU performance is hindered by the lack of data storage support; therefore‚ computers have been designed to supply data through tiering memory and caches‚ which use the hard drive in combination with random access memory (RAM) to deliver massive amounts of data to the CPU. The speed of the RAM is crucial to the performance of data delivery;

1. _____________ is the ability of a central processing unit (CPU) or a single core in a multi-core processor to execute multiple processesor threads concurrently A. Answer : multithreading B. Multicore C. Multiprocessor D. None of these 2. Multiple threads can interfere with each other when sharing hardware resources such as caches or translation lookaside buffers (TLBs). As a result‚ execution times of a single thread are not improved but can be degraded‚ even when only one thread is executing

Unit 59-Assignment 3 Task 1 The process of how the subroutine works within an operating environment is as follows. While the main part of the program is running‚ there will be a call command sent to the CPU to tell it to stop wherever the program is at‚ store the W‚ Z and status along with where in the main program the CPU is at in the stack. Then the main program is cleared from memory and the subroutine is loaded for the CPU to start processing the code. Once the subroutine has finished‚ the subroutine

Rosengarth 10/20/14 NT1110 Unit 5 Analysis 1: Pentium Flaw The nature of the Pentium flaw was in the floating – point math subsection. In certain conditions‚ low order bits of the result of floating-point division operations would be incorrect. This would lead to an error that will quickly compound in operations to larger errors when future calculations were completed. The flaw was first discovered in June 1994‚ when Intel engineers first noticed that the floating-point unit (FPU) on the chip gave
