Introduction and
types of Network
Expansion card
What is expansion card
Expansion card is a printed circuit board. It is installed in the computer that can add the functionality of the computer. For example we use the graphics card to add more 3D
graphics processing power. Fireware or USB port add fireware or USB expansion card
which provide additional connections. Most cards are installed in the PCI slot. Those are
PCI-X or PCI express. Graphics card may also installed in the AGB slot. Some cards
require open slots. Computer like Apple iMAC or other all in one machine cannot
accept expansion cards. Laptops does not use cards, but some accept removable
PCMCIA cards.
History of Expansion card
The first commercial computer which has expansion slot is the Micral N in the 1973. In tel Z80
based computer running on the CP/M had used industry standard architecture (ISA) bus. IBM MCA bus developed for the PS/2 in the 1987. In the 1997 compaq used ISA bus. In the 1993 Intel launched
PCI bus chip set for the P5 based pentium CPU. PCI introduced as a replacement of the ISA in the 1991.
Types of the Expansion cards
Expansion cards alternatively referred as the
add on card, internal card, interface adapter
and only card. It is an electronic board or
circuit added on to the expansion slot of the
motherboard of the computer. It adds to some ability of the computer. Using this additional
ability a computer can connect to another
computer in a network. Types of Expansion
card.
Interface cards (ATA, Bluetooth, IDE etc) Modem
Network card
Sound card
Video card
Video capture card
Interface Card
This card often says as the NIC. An
expansion board you insert in the computer,
so the computer can connect to the network. Most of this designed for the particular
network like protocol and media etc. Some
can able to handle the multiple network.
Types of the Interface cards.
ATA Bluetooth
Firewire
IDE
RAID
SCSI
ATA and Bluetooth
ATA
• It is the AT Attatchment, it is first approved in the may 12 1994. This interface used to connect various devices like hard drives CD ROM drives etc. It is backbone compatible, means new ATA drives apart from SATA use older ATA interfaces.
Bluetooth
• Bluetooth is the RF technology that operates on the 2.4 GHz and it’s range is the 32 meters. It has transfer rate is 1 Mbps. It is used for the computer can able to connect with the cell phone without wire.
Firewire and IDE
It is also referred to as the IEEE 1394. It is
invented by Apple in the 1995. It has also a
bus which has the bandwidth 400-800 Mbps
and the ability to handle the 63 unit on the
same bus. It is also as like as the USB. Like USB it has lot’s of the different devices such
as drives, camera etc.
IDE := It is the integrated drive electronics. It
is also known as the ATA or the parallel ATA and it has the parallel ATA only for IBM
compatible hard disk. It is different from
SCSI because it has controller for each
devices, each devices can directly connect
to the motherboard.
RAID and SCSI
RAID :=It stands for the Redundant Array of
Inexpensive Disk. RAID is connected to the
hard drive and speed up the performance of
the computer storage. It is mainly used in the
server and high performance computer.
SCSI := It is the small computer system
interface. It is the second most commonly
used interface for disk drive. It is capable to
support 8 to 16 devices. SCSI standard for parallel interface, it transfer information at
therate of 8 bit/sec. It also support seven
peripheral devices like CD-ROM, scanner etc.
It is mainly desigen for the Apple MAC but it
also used in the Unix and PC.
Modem
Modem is the modulator and demodulator. First it is released by AT&T in the 1960. It is a hardware device taht used by a computer to
transfer data over telephone lines. It translate the digital data to analog and
vice versa. Modem is called asynchoronous device because it transfer data in a stream of small packet. After receiving the packet
computer retrive the data from packet and reassemble it so that computer can use it. In this communication 1
byte is transferred in a one packet. It also use to connect the computer in
the broadband internet. Ex cable modem, DSL modem.
Network card
It is also called Network interface card. This network adapter is an expansion card that has enable the computer to connect home network.
It uses ethernet cable and RJ-45 connector. These cards are used in the laptop computer those do not have build in wireless network.
These cards found in computers those do not have integrated network on their motherboard.
Sound Card
This card is also referred as sound board or audio card. This expansion card provides the computer is the ability to produce sound through speaker. It is a peripheral card, generally it is not needed but
today almost every computer use it. It is integreted in the slot of the motherboard. Sound cards are also associated with color for unique
identifications.
Video Card
It is alternatively referred as
display adapter, graphics card or
video adapter etc. It is an internal
circuit allow monitor to display
images or video from computer.
These are connected with the
AGP, PCI on the motherboard.
Video card has three connection
on the back side VGA, S-Video
and DVI connector.
Video Capture Card
Those internal or external devices connect from
computer is capable of capturing video signal.
Using this device captured video is converted to the
stored video format. It allows you to store,
modify the video. External video captured device can connect to the computer
using USB port.
Conclusion
From above illustration expansion
cards are kyed, means they will go
to one direction. These cards are
designed for the particular
expansion slots. The back side of
the expansion card also a back
slot that allows computer to plug
into the card and interface with
computer. Apart from these cards
there are also etherent expansion
card like IBM 10GB 4 port
expansion.
