7. What are the different kinds of expansion cards? Explain them.
Ans. Network Interface Card (NIC): A network interface card is an expansion board that enables the exchange of
data between the computer and a network. ICs are designed to operate in a specific type of network, such as
Ethernet or Token Ring. Modern NICs are manufactured to be integrated into PCI expansion slots.
Sound Card: A sound card is an expansion board that enables to produce sound as output that can be heard
through speakers or headphones. It is also used to record sound as input from a microphone that is connected
to the computer and to edit or mix sound stored on a disk. Most of the sound cards are manufactured to be
integrated into PCI expansion slots.
Graphics Card (Display Adaptor): A graphics card is an expansion board that helps us process & display
videos. Modern display adaptors contain memory, therefore, many times the RAM of a computer is not used for
storing the data. Availability of memory is a major factor in determining the screen resolution and colours that
can be displayed on the monitor. Graphic cards are manufactured to be integrated into PCI expansion slots.
