What is a pci communications device?
"PCI communications device" is displayed in the Device Manager when Windows does not have a driver for a PCI device that is used for networking in some fashion. It could be a dial-up modem, Ethernet controller, or a wireless card. You will need to download drivers from your computer manufacturer to display a more specific name in the Device Manager and make the yellow question mark go away.
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.
Does wireless internet work for a PC?
Yes, you would have to purchase a USB, PCI, or PCI-X wireless device/card.
What is a PCI - Slots in the Motherboard?
Boards have evolved over the years. They started out with 1 , then went to 2 on up to about 6. As they evolved they have gotten to be fewer with the advent of pci xpress. My mother board has one PCI and 2 PCI xpress. As more devices utilize the USB bus, card slots become less necessary. Most any device on a PCI card can be found on a USB device.
Is there any way to make a device which uses PCIe x16 plug into a Mini PCI slot?
I don't think so. There are mini PCI-E to PCI-E adapters which would convert the mini to an x1 card, it seems to be very device specific however. I would generally depend on the device - in this case, I found adapters for Wifi cards.
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.
Which part connects to the PCI express or AGP buses?
AGP was designed for video controllers only. PCI-E can work with any compatible device.
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.
What is a PCI simple communications controller used for?
A "PCI Simple Communications Controller" is usually a PCI modem, but it can be other, sometimes unlikely devices, such as an audio or serial device.
How does a device initiate communication with the CPU?
io/mem wire?
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.
