What is the difference between synchronous IO and asynchronous IO?
Wiki User
∙ 11y ago
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.
What is the difference between il and lo in Italian lo with an l not an I as in lard?
il means the and io means I
What is Difference between 8155 and 8255 microprocessor?
Neither the 8155 nor the 8255 are considered to be microprocessors. The 8155 is an integrated RAM, IO, and Timer device designed for the 8085. The 8255 is an Programmable IO controller.
What is the relation between Perseus and Io in Greek mythology?
Io is an ancestor to Perseus
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 is one where the processor and the IO device share the same memory location(memory) while IO mapped IO is one where the processor and the IO device have different memory located to each other.

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.
Difference between batch operating system and multiprogrammed operating system?
multiprogramming-there is no way for single user to keep either cpu or the io divices busy at all times...
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 is the distance between Io and the earth in AU's?

What are simalrity between Io and Luna?
