What is the distance between Jupiter and IO?
Io orbits Jupiter at a distance of 421,700 kilometres. Which si about 10% further than the Moon is from Earth.
Order of brightness between Io Europa Ganymede and Callisto?
From Brightest to Dimmest: Ganymede Io Europa Callisto Use JPL's HORIZONS web ephemeris to look up apparent magnitudes of jovian satellites.
What mechanism is most responsible for generating the internal heat of Io that drives the volcanic activity?
Tidal heating is the primary mechanism responsible for generating the internal heat of Io. This is caused by the gravitational interactions between Io, Jupiter, and the other Galilean moons, which create friction and molten material within Io's interior, driving its intense volcanic activity.
What is the cause of volcanic activity on io?
The volcanic activity on Io is caused by the intense gravitational forces exerted by Jupiter and its other moons. These forces create tidal heating inside Io, leading to intense volcanic activity and a constantly changing surface.
What are the advantages of memory mapped IO?
Memory mapped IO uses a portion of RAM to handle IO requests. In this manner, instructions the CPU uses for reading and writing memory can also be used for IO, reducing the circuitry needed. This makes the CPU simpler, cheaper and more effecient.
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 advantage and disadvantage of interrupt in memory mapped IO?

What is the Difference between memory mapped IO and IO mapped IO?
In memory mapped I/O, a chunk of the CPU's address space is reserved for accessing I/O devices. In I/O mapped I/O, I/O devices are handled distinctly by the CPU and hence occupy a separate chunk of addresses predetermined by the CPU for I/O. In case of Memory mapped I/O the same address BUS is used for accessing both Memory (RAM) and the Registers of I/O devices. For I/O Mapped I/O, separate address BUS is used. As Address space is generally larger for Memory than I/O registers, the length of I/O address is larger in case of Memory Mapped I/O. For a system which uses I/O Mapped I/O, there is a requirement for a extra h/w Circuitry.
What is IO mapped?
Peripheral-Mapped IO is IO that is selected when the IO/M- line is high.
What is Peripheral-Mapped IO?
Peripheral-Mapped IO is IO that is selected when the IO/M- line is high.

Block diagram of 8257 dma controller?
it is a device to transfer the data directly between io device and memory without through the cpu so it performs a high-speed data transfer between memory and io device
If memory addresses are used by the CPU to access memory then what are io addresses used for?
To read and write to I/O
How can you distinguish memory addresses from you IO port addresses?
Not possible, both are numbers.
Which bus transfers the memory address to the IO device or to the memory device?
DMA Direct Memory Access DMA transfers data directly from the drive to memory w/out involving the CPU.
