CH1 - T / F Flashcards
The processor controls the operation of the computer and performs its data processing functions.
TRUE
It is not possible for a communications interrupt to occur while a printer interrupt is being processed.
FALSE
A system bus transfers data between the computer and its external environment.
FALSE
Is cache memory visible to the operating system?
TRUE
With interrupts, the processor can not be engaged in executing other instructions while an I/O operation is in progress.
TRUE
Digital Signal Processors deal with streaming signals such as audio and video.
TRUE
The fetched instruction is loaded into the Program Counter.
FALSE
Interrupts are provided primarily as a way to improve processor utilization.
TRUE
When can an interrupt occur during program execution?
The interrupt can occur at any time and therefore at any point in the execution of a user program.
How has memory access speed changed compared to processor speed over the years?
Over the years memory access speed has consistently increased more rapidly than processor speed.
What is an SMP?
An SMP can be defined as a stand-alone computer system with two or more similar processors of comparable capability.
What does the Program Status Word contain?
The Program Status Word contains status information in the form of condition codes, which are bits typically set by the programmer as a result of program operation.
Can you give an example of a multicore system?
An example of a multicore system is the Intel Core i7.
How is the Hit Ratio defined in a two-level memory hierarchy?
In a two-level memory hierarchy the Hit Ratio is defined as the fraction of all memory accesses found in the slower memory.
What role does the operating system play in relation to hardware and users?
The operating system acts as an interface between the computer hardware and the human user.
