21 Questions
In the context of interrupts, what occurs when an I/O device completes an operation?
The Program Status Word is updated with the current state of the interrupted program.
How does a multiple interrupt situation affect the interrupt processing?
It can lead to nested interrupts.
What is the purpose of an Interrupt Handler in the context of interrupt-driven I/O?
To handle the interruption caused by I/O devices.
How does interrupts relate to Performance Scaling in a computer system?
Interrupts can improve performance by reducing CPU idle time during I/O operations.
What determines which cache location the block will occupy?
Mapping Function
Which I/O technique requires the processor to actively intervene in the data transfer between memory and an I/O module?
Programmed I/O
What is the main drawback of Programmed and Interrupt-Driven I/O methods in terms of transfer rate?
Limited by processor speed
Which I/O technique transfers data directly to and from memory without involving the processor during the transfer?
Direct Memory Access (DMA)
In Symmetric Multiprocessors (SMP), what characteristic describes processors sharing access to I/O devices?
Availability
What system feature allows for the addition of another processor to enhance performance without halting the machine in SMP organization?
Availability Incremental Growth
What is the primary advantage of Symmetric Multiprocessors (SMP) regarding performance?
Performance scaling with multiple processors
What characteristic defines a Multicore Computer?
Combining two or more processors on a single die
In what type of I/O operation does the processor repeatedly check the I/O module status until the instruction is complete?
Programmed I/O
Which mechanism allows for efficient data transfer between memory and an I/O module without involving the processor in each transfer?
Direct Memory Access (DMA)
What aspect of a Multicore Computer distinguishes it from traditional single-core systems?
Combining multiple processors on a single chip
What is the main purpose of interrupts in a computer system?
To improve processor utilization
In a Symmetric Multiprocessor (SMP) system, how is the workload typically divided among the processors?
Each processor executes a copy of the same program
What is the function of System Bus in a computer system?
Facilitates communication among processors, main memory, and I/O modules
How do interrupts affect the normal sequencing of a processor?
Interrupts pause the processor's current task to handle another task
What role does Program Counter (PC) play during instruction execution in a computer system?
Holds the address of the next instruction to be executed
How does a multicore computer differ from a single-core computer in terms of performance?
Multicore computers can execute multiple instructions simultaneously
