The process of selecting the next job that will run on the CPU belongs to the short-term or CPU scheduler. The CPU scheduler can only pick from the jobs that are already in memory and ready to go. The scheduler works in cooperation with the interrupt system.
• The scheduler assigns the CPU to perform computation on behalf of a particular process or thread within a process.
• CPU can be "borrowed" from its current process by an interrupt. It is under the control of external devices not scheduler. Interrupts can be disabled for a short time.
• When a process or thread requests an I/O transfer, it normally becomes ineligible to use the CPU until the transfer is complete. This means that the scheduler will have to choose a new process or a new thread within the same process to use the CPU.
• The process or thread that requested the I/O again becomes eligible to use the CPU when the I/O transfer is complete.
CPU I/O Burst Cycle
The execution of a process consists of an alternation of CPU bursts and I/O bursts. A process begins and ends with a CPU burst. In between, CPU activity is suspended whenever an I/O operation is needed.
• If the CPU bursts are relatively short compared to the I/O bursts, then the process is said to be I/O bound. For example, a typical data processing task involves reading a record, some minimal computation and writing a record.
• If CPU bursts are relatively long compared to I/O bursts, a process is said to be CPU bound. A number crunching task involves an I/O burst to read parameters. A very long CPU burst and another I/O burst is required to write results

How do you adjust the speedometer cable on a 1998 Ford Escort SE?
Sorry to burst your bubble but their is no speedometer cable on a escort, it utilizes a input and output speed sensor on the transmission, and the Drivers information center uses a tiny motor that receives a signal from the Ecm, it uses the output speed sensor from the transmission to give you a vehicle speed. They just dont build them like they used to.
What limits the output of an electrical generator?
The amount of voltage of an electrical generator will determine the limit of the output of energy. If the voltage is too high, it can burst the pipes causing it to shut down.
What are the properties of an op-amp?
Properties of an op-amp are as follows: 1.Very high open loop gain which remains constant over the frequency range in which the device is to be used. 2.Very high input impedance to minimize the current drawn by the circuit with little losses. 3.Very low output impedance 4. They are stable, i.e. not liable to burst into parasitic oscillation. 5. They are free from drift caused by ambient temperature changes.
How do you calculate the burst strength of paper corrugated box?
The burst strength of a paper corrugated box is typically calculated by conducting a burst test. The test involves applying pressure to the box until it ruptures, and the pressure at which this occurs is recorded as the burst strength. The burst strength is commonly measured in pounds per square inch (psi) or kilopascals (kPa).
What neutralises akali?
To neutralise Akali, focus on purchasing control wards to reveal her while she's in her shroud, as well as building health and resistances to survive her burst damage. Coordinate with your team to lockdown Akali and burst her down before she can escape. Champions with crowd control abilities and high burst damage can also be effective in dealing with Akali.
