MOTHERBOARD CONNECTIONS

This is a brief description of the common connectors that you will see on a motherboard.

On-board Cluster

    Keyboard connector
         AT - large 5-pin
         PS/2 - small
    Mouse connector
    Printer plug
    Sound ports
    Ethernet (RJ45)
    USBs
    And others

Capacitors and BLOWN CAPS

The capacitors or caps

 on the motherboard are able to store small amounts of electrical charge within for use at times when there is a 
 sudden demand for power from one of the devices.  If they become overloaded, they puff up on top and so can be      
 identified as blown.  The motherboard may continue to function for awhile with a blown cap but it will soon                       
 break down, so Freegeek will not build a system if there is a blown cap present.    
   

ZIF socket or processor slot

The socket

lies flat on the motherboard and the gold pins on the CPU fit down into its holes, with its heat sink and fan on : top. ZIF stands for Zero Insertion Force, the amount of force that is acceptable when sliding the pins back : into their holes.

The slot processor

stands up sideways on the motherboard in a slot that looks similar to a card slot. The Pentium II and early : Pentium III processors are this type, but noone is manufacturing them any more. It too has a heat sink and fan : attached to the side to keep the CPU from overheating.

Drive connectors

    IDE
    SATA (Serial ATA)
    SCSI
    Optical drives such as CD and DVD
    Floppy

Bridges and communication facilitators

    Northbridge
    Southbridge
    AMR and related type slots

What type of keyboard connector does it have?

Does it have both IDE and SATA hard drive connectors?

See how many motherboards you can find that have blown caps.
