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.
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.
The maximum number of Io devices can be interfaced with 8085 in the Io mapped Io technique?

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 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 advantage and disadvantage of interrupt in memory mapped IO?
disadvantages of interrupt
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.
How is the height of a mountain mapped?
the height of a mountain is mapped by a helicopter and a laser
What does io mean in English?

When was We Mapped the World created?
We Mapped the World was created on 2010-04-05.
How do you put the word mapped in a sentence?
As a verb. The terrain has been mapped for the upcoming incursion.
