Why do we need an Expansion card? Where do we use this? What is expansion bus? What is the Expansion bus and how does expansion bus work? Has all single-board made provision for expansion cards? Is it possible to install multiple RS232 ports, multiple and higher bandwidth Ethernet ports? What are the differences between “low-profile” cards and “Standard” cards? How many expansion cards basically can be added to the system? What is a backplane system? If many expansion cards are added to a system, does any effect on power consumption? Thank You
Let me introduce with Expansion card
Hello John!
Expansions card gives extra features and extends our computers capability or memory. It [primarily provide the features that is not included with motherboard. Expansion Bus can multiply or duplicate the add-in card slots in the motherboard. Expansion bus is actually known as the USB devices that we use. Low profile cards compared to standard profile card uses smaller ports or space inside tower or motherboard. Low profile cards consumes smaller memory and hard disk spaces for operation. The minimum number will be four for the expansion cards. Power will be greatly affected. Backplane is a group of relative pin forming a computer bus. Adding more expansion cards contributes to the power consumption. The more expansion cards, the more power it uses. We can install multiple Rs232 ports and connectors but I will not suggest of doing that. It will limit you in data load, it is so slow in connection speed.
