Select which item is an example of making the common case fast. its not avoiding branches using well designed code libraries using assembly using SIMD avoiding branches Which of the following is not an item used to support virtual memory on an x86 processor? segment descriptor GDTR Instruction pointer segment descriptor Local descriptor table LDTR What is the name used for the switching of the CPU from one process or thread to another? Which statement is true about the assembly programs we have been writing? The operating system manages how many cores it run runs as a process on a single core there is no way to make assembly programs access memory faster the operating system manages how many cores it runs on there can be only one instance of our program Which items are multi tasking scheduling methods? (l selected RTE, round robin and it was incorrect) Multi level feedback queue FIFO RTE round-robin the person generally generally regarded to be the first programer is who? Ada Lovelace Alan Turing Robert Fulton Charles Baddage the FPU uses which notation? postfix infix prefix In which magazine did Bill Gabs and Paul Allen see the first personal computer? New yorker -Popular electronics -Time -Playboy

Explanation / Answer

8)

Instruction pointer - It is also known as program counter - it shows the processor which instruction to be executed next .But, it no way deals with memory.

11)

assembly program that we have been writing runs as process on a single core

13)

FIFO - first in first out basis-----ON this basis , the operating system serves each tasks at that particular time .So,by which multi tasking can be acheived

20)

the FPU uses SCIENTIFIC NOTATION . ------ In assembly program, it follows IEEE format which is an form of scientifc notation
