what is a pci card..?

a card which you plug into mainboard's pci slot
 

Re: what is a pci card..?

Speaking of cards, what might industry use to control a communications network and a test fixture interface combined. In other words the computer has to control local communication with a product through the use of a fixture as well as maintain access to a larger network through the use of something like a local business type network. Is there any such card on the market that combines the two functions? Where I work, I think they use such a card.

PCI card= Peripheral Component Interconnect card.

A digital TV tuner PCI card is basically a computer component that slots into a PCI slot on a motherboard on your PC, in a similar way that a sound card or network card does. The PCI card has an on board tuner and demodulator and a number of other electronic components.

Like analogue TV Tuner cards that have been around for a while a digital TV tuner card will allow you to receive Digital Video Broadcasts (DVB). In Australia digital broadcasts are delivered via satellite (DVB-s), Terrestrial (DVB-t) and cable (DVB-c), with the latter being a very new development in Australia. Different cards are manufactured for the different broadcasts, as the standards and specification of each broadcast are different requiring different tuner/demodulators with different characteristics.

PCI card is simply a card that fit into a PCI slot.

PCI standard is well-defined, up to the connector.

PCI bus have it's advantages over older ISA/EISA bus as it is faster, but can also support request from any of the interfaces to any of the interfaces.

For example, in the older ISA bus structure, the CPU was the master, and all ISA interfaces (cards) were slaves. The CPU made request to the cards, and the cards just answered the requests.

In PCI, you can have the CPU talking to a card, but you can also have a card talking directly to another interface. A good example is some PCI video card, which use off-board (shared) memory. The CPU tell the card where to get it's pixel data, and then, the card read the data directly from the mainboard memory, without any intervention from the CPU.

Older (ISA) cards achieved similar process via the use of DMA. Though, the CPU was responsible for programming the DMA, and initiating the transfer. With PCI, there's no more need for DMA, and the process doesn't even require the CPU to be aware. Transactions are transparent to the CPU.
