What is the difference between anecdotes and examples?
An anecdote is a story, which can be told as an example of something. An example however is used to exemplify something, but is not necessarily an anecdote.
Ordinal level of measurement?
Where you order the measurements according to some rule but there is no straightforward relationship between the categories. For example, with measurements classified as: short, medium, tall. It is not possible to say whether the difference between medium and short is smaller than/equal to/larger than the difference between tall and medium.
What is the difference between a biased and unbiased sample?
Biased- (Not random) Unbiased-(Random) Example: (ubbiased) Woman takes random people to take a survey.
The interval of a graph is the difference between any two numbers on the scale?
Yes, the interval of a graph is the difference between any two consecutive numbers on a scale.For example, if the scale read: 2,4,6,8,10 then you could do 4-2, 6-4, etc. to find the interval. (which is 2)
What is difference between measurement and estimation?
The difference between a measurement and an estimation is that a measurement is an exact data while an estimation is a guess as to what something may measure. For example, you can use a ruler to get the exact measurements of a piece of paper. However, if you don't have a ruler, you can make an educated guess as to what the paper's length and width measurements may be.
What is difference between vectored and non vectored interrupts?
Vector interrupt --> when processor directly call the respective isr when interrupt occurs so, address of respective isr is usually save in register. Non interrupt Vector --> In this case when interrupt occurs the processor calls a generic isr and in generic isr uaer has to call respective isr by checking status register.
What is interrupt vector?
When a processor is interrupted to do a particular task,Program counter should be loaded with the the address of subroutine(task).If the processor automatically generates the address then it is known as vectored interrupt.for example if 8085 microprocessor is interrupted through RST 5.5 pin,then processor multiplies 5.5 by 8 and converts it to Hex address.If user has to provide address of subroutine using CALL instruction then it is known as non vectored interrupt
What is the verb for interuption?
The verb of interruption is interrupt. For example "to interrupt someone or something".
Interrupt in a sentence?
Here is an example sentence using the word interrupt. Bill will always interrupt Sally when she is telling a story about him.
What is the difference between has and have and give an example?
the difference between has and have is that you use has in sentences with : ( she , he and it ) for example : she has a book . but you use have in sentences with : ( I , you , we and they ) for example : you have a book , I have a book .
What is key difference between a trap and interrupt?
An interrupt is generally initiated by an I/O device, and causes the CPU to stop what it's doing, save its context, jump to the appropriate interrupt service routine, complete it, restore the context, and continue execution. For example, a serial device may assert the interrupt line and then place an interrupt vector number on the data bus. The CPU uses this to get the serial device interrupt service routine, which it then executes as above.A trap is usually initiated by the CPU hardware. When ever the trap condition occurs (on arithmetic overflow, for example), the CPU stops what it's doing, saves the context, jumps to the appropriate trap routine, completes it, restores the context, and continues execution. For example, if overflow traps are enabled, adding two very large integers would cause the overflow bit to be set AND the overflow trap service routine to be initiated.
What is interrupt mechanism?
At the beginning of each FDE cycle, each bit in the interrupt register is checked in turn. This register is a special register in the CPU that takes note of when an interrupt has happened. Each bit in the register represents a different kind of interrupt. If a bit has been set, that would indicate an interrupt has happened! The CPU has to decide whether to service the interrupt immediately, or leave it till later. For example, if 2 interrupts have happened at the same time, one of them has to wait! Which one? That depends upon which one is the least important! Some interrupts are more important than others and so need to be done before others. What about the situation where one interrupt is currently being serviced by the CPU and another happens? Again, it depends on how important the new interrupt is compared to the one already being done. If it is more important, then the cpu will want to service it immediately. When the CPU decides to service an interrupt, it stops processing the current job, 'pushing' the contents of its registers onto the stack. This would include, for example, the contents of the Program Counter and the accumulator. The CPU is now free to work on another piece of software but can return to what it was doing after the interrupt has been serviced because it has saved where it was. It then transfers control to the interrupt handling software for that type of interrupt using the vectored interrupt mechanism. When it has finished servicing the interrupt, the contents of the stack are 'popped' back into the appropriate registers and the CPU continues from where it left off before the interrupt happened.

Which of the words interupt and interrupt are the right spelling?
The correct spelling of the word is interrupt.Some example sentences with this word are:I asked you not to interrupt the class.We interrupt this programme to bring you some breaking news.

Difference between software interrupt and hardware inerrupt?
Hardware Interrupt: Each CPU has External Interrupt lines(about 7). Other external devices line keyboard, Mouse, Other controllers can send signals to CPU asynchronously. Software Interrupt:is an interrupt generated with in a processor by executing an instruction . Software interrupt are often used to implemented system calls because they implemented a subroutine call with a CPU ring level change.
HOW IS SOFTWARE INTERRUPT INITIATED?
Interrupt signals initiated by programs are called software interrupts. A software interrupt is also called a trap or anexception. A signal informing a program that an event has occurred. When a program receives an interrupt signal, it takes a specified action (which can be to ignore the signal). Interrupt signals can cause a program to suspend itself temporarily to service the interrupt. Interrupt signals can come from a variety of sources. For example, every keystroke generates an interrupt signal. Interrupts can also be generated by other devices, such as a printer , to indicate that some event has occurred. PCs support 256 types of software interrupts and 15 hardware interrupts. Each type of software interrupt is associated with an interrupt handler -- a routine that takes control when the interrupt occurs. For example, when you press a key on your keyboard, this triggers a specific interrupt handler. The complete list of interrupts and associated interrupt handlers is stored in a table called the interrupt vector table , which resides in the first 1 K of addressable memory.
