In computingthe expansion cardexpansion boardadapter card or accessory card is a printed circuit board that can be inserted into an electrical connectoror expansion sloton a computer slotbackplane or riser card to add functionality to a computer system via the expansion bus. An expansion bus is a computer bus expanson moves information between the internal hardware of a computer system including the CPU and RAM and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer. Even vacuum-tube based computers had modular construction, but individual functions for peripheral devices filled a cabinet, not just a printed circuit board. Expansion cards allowed a processor system to be function to the needs of the user, allowing variations in the type of devices connected, additions to memory, funnction optional features to the central processor such as a floating point unit. Minicomputers, starting with the PDP-8were made of multiple cards, all powered by expansion communicating funtcion a passive expansin.
As mentioned above, every motherboard model is unique, so to determine the type of expansion slots on the motherboard, consult the board's specifications and owner's manual.
Functions Of Expansion Slots
You can also open the computer case and visually examine the motherboard. Computers have expansion slots to give the user the ability to add new devices to their computer. For example, a computer gamer may upgrade their video card to get better performance in their games. An expansion slot allows them to remove the old video card and add a new video card without having to replace the motherboard.
Today, the most commonly used expansion slot used and found on computer motherboards is the PCI Express expansion slot.

The expansion cards finction the different types of cards or adapters which are used in computer to improve the performance and compatibility of any system.
This means that they are used to expand the working performance of the system.Mar 07, · Expansion Slots on the motherboard. The slots provide connection to the system bus. There are different kinds of slots available, one is PCI (Peripheral Component Interconnect) which is a general expansion slot used in the old time. The other modern expansion slots like PCIe (PCI Express) are used to provide different pathways to the system bus. Expansion slots allow you at add special higher performance features to your computer. Probably the most common is a high performance graphics card. However some other possibilities include an I/O card if you are using it in a lab environment, a music card if you are using it as a home entertainment system or for editing, you can also add USB or Firewire ports to tie in more peripherals. Jan 04, · The Types of PC Expansion Slots You can expand your PC internally by adding additional circuitry boards. Those boards, or expansion cards, plug directly into expansion slots on the motherboard (as shown in this figure). So, you can expand your computer system by adding options not included with the basic PC.
These cards can be available in modular form so that we can attach or remove them from the slots or they are integrated on the motherboard and are fixed. There are many types of expansion cards used in the computer system and I will talk about the four basic types of these which are:.
Network card is used to connect our computer system to the computer networks over the Internet OR it is used for communication between our system and the other computer networks. NIC card has the pins at the bottom so that it can be fixed in the expansion slot on the motherboard.
Similarly, it has Rj port at the back of the card which is used to connect to the LAN network.Mar 07, · Expansion Slots on the motherboard. The slots provide connection to the system bus.

Feb 16, · Hence the PCI slot. The function of a PCI slot is to provide a common interface that can be adapted for virtually any use. It allows you to design an expansion card and have it work out of the box with a computer (assuming you don’t have any conflicts on the software side.
There are further two types of NIC cards, one is for wired network and the other is for wireless network. Wired network card has the port at the back while a wireless network card has an antenna attached to it.
This card is used to provide the graphical a like images, videos etc.
Computing Technology with IT Fundamentals
It requires a high processing power to convert the instructions to their graphics. It is also called the Graphic Card or Display Card.
Video card has its own processor which provide the interface between the Operating System and the Monitor to display. Sot is attached to the motherboard through its pins at the bottom and it has also different kinds of ports which are expanwion to connect different kinds of the output display devices like monitor, projector etc. The following figure shows the video expansion card with its different parts.

Modem is same like the network card fynction it is an older technology as compared to the NIC card. It is used to function the computer system to the Internet through the telephone line. Typically it has two ports for RJ connectors, one is used to connect the telephone line while the other expansion used to slot the telephone. It converts the digital signals of our system to analogue signals of the telephone line and vice versa.
The following figure shows the Modem alot two RJ jacks.

Audio card is used to convert the electrical signals to the audio signals or sound which we can hear. The audio cards has different kinds of ports or jacks attached fundtion it and these ports are used to connect the headphone, Microphone, speakers and other digital audio devices. The following figure shows the Audio card and its different ports.
