What is the difference between synchronous IO and asynchronous IO?

Anonymous

∙ 12y ago

Updated: 8/17/2019

If a process requests that the O/S write data to disk, and has to wait for it to be written before continuing, then that is Synchronous. If the process does not have to wait for the write to be completed, that is Asynchronous.

Synchronous is real-time.

How long is a day on the moon Io?

A day on Jupiter's moon Io is 1.769, 137, 786 days. Io is in a synchronous orbit, which means that a moon's orbit around its parent planet is the same as one of the moon's day.

Is IO tidally locked with Jupiter?

Yes, Io is tidally locked with Jupiter, meaning that Io's rotation period is synchronous with its orbital period around Jupiter. This causes the same side of Io to always face Jupiter. The intense gravitational forces from Jupiter and its other moons create tidal heating on Io, leading to volcanic activity and a geologically active surface.

List and briefly define three techniques for IO operations?

Blocking IO: The program will pause and wait until the IO operation is complete before resuming. This technique can lead to inefficiency if there are multiple IO operations. Non-blocking IO: The program continues to run while waiting for the IO operation to complete. This allows for better efficiency when handling multiple IO operations simultaneously. Asynchronous IO: The program initiates the IO operation and continues executing, without waiting for the operation to complete. A callback function is usually provided to handle the result once it is available. This allows for better performance in handling large numbers of IO operations.

Differentiate between memory mapped IO and IO mapped IO?

Memory mapped IO involves using memory addresses to access IO devices, treating them as if they were memory locations. IO mapped IO involves using separate IO addresses distinct from memory addresses to access IO devices. Memory mapped IO simplifies programming and can improve performance, while IO mapped IO offers better separation between memory and IO devices.

What is the distance between Jupiter and IO?

What is the Difference between memory mapped IO and peripheral mapped IO?

A memory mapped IO device is an IO device that responds to a specific address when IO/M- is low. A peripheral (or IO) mapped IO device is an IO device that responds to a specific address when IO/M- is high.Many system designers ignore IO/M- in favor of memory mapped IO.This eliminates one term in the chip select logic for every device.This allows you to use all addressing modes and instructions when manipulating an IO device, as opposed to using only IN and OUT.This allows you to potentially have more than 256 different IO devices.The downside is that you reduce the addressable main memory in the system, i.e. you cannot have all 64K available to you, but this is not generally a problem in most controller designs. You also must decode 16 address lines instead of just 8 when accessing the device.

What causes volcanoes on Io?

Io's energy source is external---Jupiter's gravity. Io orbits very close to Jupiter, the planet's huge gravitational field produces strong tidal forces on the moon, resulting in a large tidal bulge. If Io were Jupiter's only satellite, it would have long ago have come into a state of synchronous rotation with the planet. In that case, Io would move in a perfectly circular orbit with one face permanently turned toward Jupiter. The tidal bulge would be stationary, and there would be no internal stresses and no volcanism. However, Io experiences tidal pull from Jupiter's other moons also.
