Manufacturing companies list of SMD ICs

1) ITE2) WINBOND3) ALI4) SMBC

Checking process : compare to ground 14%pins shows continuity.

GATES:

Inside of IC is called gates ( input,output functions). Inside of gates is 2 to 3 transistors arefunctions.

1) AND GATE

2) OR GATE

3)NOT GATE

4)NAND GATE

5)NOR GATE

AND GATE:If any one input is low so output will be low.

ICH - input/output controller hubBUS - group of wires which crries information fom one drive to another drive is

called as bus.(or)

Group of copper traces which will carry the data bits.

Chipsets :

Chipset contains the following controllers.

1) Memory controller (north bridge)2) System controller (south bridge)3) Peripheral controller (south bridge)

System controller contains the following controllers.1) Oscillators & timers2) Interrupt controllers3) DMA Mangement4) Power management

1)Oscilators & timers:

which create time base(pulse )required for micro processor,memory and the rest ofthe computer to operate.

2)interput controllers:

Which manage the hardware interputs that give priority to important functions.3)DMA management:

Which governs the data transfer to and from independently of the micro processorto free the chip upto for more important duties(like thinking)

4) Power management:

Which watches over all the electrical use of the computer to save power and innote book machines conserved batter reserves.

MIDI ------Musical instrument digital interface

MIDI:

MIDI is the language spoken among musical instruments andcomputers .MIDI is not audio signal ,multimedia presentation that gives MIDI aremore professional sounding and easier to create. They also are more efficientbecause the file sizes are smaller and therefore require less resolves to press thefiles. The PC needs an MIDI interface to translate MIDI data to binary data.

Normally an MIDI interface is available with sound cards.
