from I/O. Data operation (do): Perform the operation indicated in the instruction. Operand store (os): Write the result into memory or out to I/O. 3.3 (1) Disable all interrupts while an interrupt is being processed. (2) Define priorities for interrupts and to allow an interrupt of higher priority to cause a lower-priority interrupt handler to be itself interrupted. 3.4 Memory to processor: The processor reads an instruction or a unit of data from memory. Processor to memory: The processor writes

disabling interrupts frequently can affect the system’s clock. Explain why this can occur and how such effects can be minimized. Answer: The system clock is updated at every clock interrupt. If interrupts were disabled —particularly for a long period of time —it is possible the system clock could easily lose the correct time. The system clock is also used for scheduling purposes. For example‚ the time quantum for a process is expressed as a number of clock ticks. At every clock interrupt‚ the scheduler

a guy name mike and he is the main guy that do most of the talking but there are other people on the show that interrupts when he talking . He does not use open ended questions much. Also it is a great show to watch because when a main topic is brought up about a person like Kobe Bryant mike is the first person to say something but it is five people at the table and they just interrupts mike when he is talking but he do get his point across to the people. In closing Around the Horn is a great sports

If your teacher says something incorrect in a class‚ what will you do? 1) Interrupt your teacher right away 2) Keep silent 3) Correct your teacher after the class We are not unfamiliar with sometimes our teacher could make subtle mistakes when teaching in the class. And there is no denying that even the sage could make the mistake‚ and so teacher could. Therefore‚ in my opinion‚ correcting my teacher after the class is the best choice among others. Firstly‚ correcting teachers after the class
