No.
An I/O device can be either internal (installed inside the computer case) or external (installed outside the case).
Internal:
network card, sound card, video capture card, and video card.
External:
keyboard, monitor, mouse, printer, scanner, digital camera, and flash drives.

What is IO bar for pci device?
Fusion-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.
An input and output device can only be internal?
That's not compulsory
Is io a scrabble word?
No, it is not. It is an abbreviation of 'Internal Organ' or its similar.
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.
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
How do you xxplain how DMA offers an improvement over CPU programmed IO?
It offloads actual IO processing from CPU to the device hardware. This frequently allows the IO device to perform its operations on cycles that the CPU could not have made use of anyway, resulting in a double benefit.
How does a device initiate communication with the CPU?
io/mem wire?
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.
Is modem a processing device?
Not in the strictest sense. It is an IO device and a converter. They often do have processors on them, and they are used for conversion, compression, and decompression.
If you need to install an external peripheral to take the place of a failed internal component in a notebook what do you first do to a disable the internal component?
To substitute an internal device with an external device, first go into the CMOS setup and disable the internal device.
Full form of Io?
in computer's area io(device) means input and output devices.
