Question
9. After an interrupt happens the control will be passes to: 1) The Interrupt handler 2) The Error handler 3) The user notification program 4) The OS VO system 10. In order to be able to react on external interrupts correctly the computer must: 1) Periodically (for ex. every 1 mlsec) check the existence of interrupt signals 2) Wait for the signal from the user about interrupts 3) Check for the interrupts at the end of every instruction cycle 4) Continuously poll all possible interrupt sources to find active interrupt signal 11. A bus in a computer system: 1) 2) 3) Is a private transmission media for various computer component Is a shared transmission media Allows multiple devices connected to the bus successfully transmit at the same time All of above 4) 12. In order to control data transmission on the bus the following method should be used: 1) Asking a user permission to transmit data 2) Input data back after transmission and compare with data sent. 3) Sending data through the bus several times 4) Centralized or distributed arbitration. 13. A typical PCI Express: 1) Is not a bus system but rather a communication system based on switch 2) Is a PCI bus with higher transmission speed 3) Is a modification of the ISA bus 4) Developed specifically to control Universal Serial bus (USB) 14. What is wrong? In modern computer system an instruction may be: 1) Executed directly by CPU HW 2) Implemented as sequence of microinstructions and interpreted by CPU 3) Executed as sequence of other CPU instructions 4) Executed by implementing so-called sequence of steps which is frequently referred as the fetch-decode-execute cycle.Explanation / Answer
9.
Interrupt handler
Explanation:-
It controls the interrupt mode
No other interrupts to enter
10.
Periodically check the existence of interrupt signals
Explanation:-
It checks the interruption
11.
All the above
12.
Sending data through the bus several times
Explanation:-
It transfers the data
It tranfers the communication data
13.
Is a PCI bus with higher transmission speed
Explanation:-
It transfers the PCI express
It is a point to point transmission
14.
Implemented as sequence of microinstructions and interpreted by CPU
Explanation:-
Basically It consists of microintructions
It controls the CPU
It has a set of instructions
15.
A method of executing instructions when an instruction is executed by several
CPU’s in parallel and the results are compared
Explanation:-
It implements parallelism
It is a single processor
16.
All registers are connected to the bus
Explanation:-
Bus is a single unit.It contains all the registers
17.
All the instruction codes must include memory address
Explanation:-
It should have a specify the memory address
18.
Is a register that typically contains condition codes plus other status
information(flags)
Explanation:-
These flags make the decisions in conditional statements
19.
Call saves the return address
because,
The address of the next instruction after the call instruction is called return address
so it saves the return instruction
20.
Single instruction multiple data execution
