HI EVERYBODY!
I OPENED UP THE CPU BOX OF MY COMPUTER FOR THE SECOND TIME
I COULD RECOGNIZE THE CPU CHIP ON THE MOTHERBOARD,A THICK BOOK TYPE HARDDISK!,AND A FEW OTHER BUSES.CAN ANYONE HELP ME IN KNOWING WHAT TYPES OF BUSES ARE THESE.THOUGH I KNOW A FEW WORDS LIKE ISA BUS,PCI BUS ETC.WHAT DO THESE BUSES ACTUALLY DO AND WHAT ARE THE DIFFERENCES B/W THESE BUSES.DO WE HAVE ANY OTHER BUS IN THE SYSTEM?

It really depends a lot on the vintage, etc.
post a photo and someone can mark it up with descriptions.

can anyone tell me the names of common buses like PCI,ISA etc and the functions they perform?
my cam is not working so i cant post a pic of my PC

The information you require can be found in
Tom's Guides here: http://www.tomshardware.com/
Or at :
http://www.anandtech.com/


If you know the name and # of your motherboard you can find descriptions and pictures on the manufacturers homepage.

simply put

ISA = brown (old computers)
PCI = white
PCE (PCI express) = black but reversed
AGP = black
Most modern pcs have
<Disclamour> This is very simply put </Disclamour>

The difference b/w an ISA slot and a PCI slot is that ISA slots are 16 bit and PCI slots are 32 bit. ISA slots are used in old computers thay are long usually black coloured but you should know that ISA slots are no longer manufactured.For more info try to search in google or sth.

I should warn against using color of the connector to determine the type of buss. I have seen and purchased these connectors in different colors in the past. There are other obvious differences in the buss connection. You cannot insert a card into the wrong buss. You should look at the characteristics of the connector to see the differences.

ISA is no longer commonly available in nowadays motherboard.... except some industrial mini size controller board

and do not "visually" distinguish the bus .......... get yourself a manual of the motherboard..... it will clearly state what are these!

hi there!
any difference in data flow and protocols used in ISA AND PCI?or are they same
for a particular hardware interfacing are they interchangable?

hi everybody!
actually i wish 2 know the reason behind using so many buses in a computer .why not a single bus for all types of communication.like for example,
why to connect printer and digital camera on different buses or ports?
plz reply soon

[trigger]

It is a technology trend in using different buses......

the newest have the higher data flow bandwidth and faster speed.

 

[prateeksikka]

hi trigger!
is there any difference in the protocols which the buses use?
or is it the same.i also wish to know why we connect some devices on parallel port while some on serial port.
