What causes Deadlock?
A set of processes is deadlock if each process in the set is waiting for an event that only another process in the set can cause.
What is a volatile keyword How it helps in the embedded perspective?
Compiler dont know the value of the variable, That variable can set at any time in the process running. ex interrupt or any bit set.
What is the process called when a new set of instructions begin before the previous set is finished?
Hypertheading
The sun ultra spark processor has multiple register sets what else must happen if the new context is in memory rather than in a register set and all the register sets are in use?
The CPU current-register-set pointer is changed to point to the set containing the new context,which takes very little time. If the context is in memory, one of the contexts in a register set must be chosen and be moved to memory, and the new context must be loaded from memory into the set. This process takes a little more time than on systems with one set of registers, depending on how a replacement victim is selected
What is the technological system for an alarm clock?
GOAL: wake somebody up INPUTS: alarm set, clock with battery and working PROCESS: the clock arrow moves as the time passes OUTPUTS: the clock arrow reaches the set time FEEDBACK: the alarm clock alarms making a sound and somebody wake up I think that is it:) just got that question for the science HW
What is the process with priority 0 in Windows?
Pririty zero can be set from the task manager. It is the lowest priority of a process. Process with priority zero will be processed least.
How does the kernel decide which request gets the higher priority?
Fire up task manager by pressing ctrl+alt+del . Click on process tab. Right click on process you want to configure. Go to set priority option and set the priority you need.
How does the operating system share the CPU in a multitasking system?
There are two basic ways of establishing a multitasking environment; timeslice and priority based. In a a timeslice multitasking environment each application is given a set amount of time (250 milliseconds, 100 milliseconds, etc) to run then the scheduler turns over execution to some other process. In such an environment each READY application takes turns, allowing them to effectively share the CPU. In a priority based environment each application is assigned a priority and the process with the highest priority will be allowed to execute as long as it is "ready", meaning that it will run until it needs to wait for some kind of resource such as operator input, disk access or communication. Once a higher priority process is no longer "ready", the next higher process will begin execution until it is no longer "ready" or until the higher priority process takes the processor back. Most real-time operating systems in use today tend to be some kind of combination of the two.
If more than on IRQ is up at the same time how does the interrupt controller select with to process first?
The priority of interrupts on the 8085 is, in order of decreasing priority, TRAP, RST7.5, RST6.5, RST5.5, and INTR. The priority of interrupts on the 8259 is dependent on the priority mode set by the programmer, it can either be 1.) fully nested mode, where IRQ0 has highest priority, 2.) auto rotation mode, where each has equal priority in a rotating scheme, and 3.) fixed rotation mode, where one is selected as highest by the programmer.
How nice value is used to calculate process priority?
In Linux we can set guidelines for the CPU to follow when it is looking at all the tasks it has to do. These guidelines are called niceness or nice value.The Linux niceness scale goes from -20 to 19. The lower the number the more priority that task gets. If the niceness value is high number like 19 the task will be set to the lowest priority and the CPU will process it whenever it gets a chance. The default nice value is zero.
Why would you set the priority of an email to 'high'?
When the contents of the email are of high priority to the recipient.
What is meant by Aperture priority?
Aperture Priority has the camera set the shutter speed for you allowing you to set the aperture and it will set what shutter speed it thinks is best for your current light situation.
What task manager tabs allows the priority of a running process to be configured?
The 'Processes' tab allows this configuration. Simply right click on the name of the process you wish to change, go to 'Set Priority' and select the proper priority. Be careful - setting the priority too high could cause your computer to stop responding if the application tries to use too many resources. Setting it too low may cause the application to work improperly. If you do not know the name of the process, but you see the application listed in the 'Applications' tab, right click on the application name and select 'Go To Process'.
How do you you set the boot priority sequence in Windows 2000?
You don't. Boot priority is specifed by the BIOS, not Windows 2000.
What types of priority are available in email?
In gmail, you can set up priority inbox, but apart from that, I don't think so.
What is the difference between online processing and realtime processing?
The different is that real-time processing occurs immediately an a function is set to action. Online processing involves putting functions in a queue and can take time to process.
What is the resident set and working set of a process?
Resident set is that portion of the process image that is actually in real-memory at a particular instant. Working set is that subset of resident set that is actually needed for execution. (Relate this to the variable-window size method for swapping techniques.)
