Chipset

• 1.North Bridge -it controls the Processor and
  RAM (High speed devices) -it is placed nearer to
  the processor -it also contains graphic processor
  -it is also called as GMCH (Graphic Memory
  Controller Hub)
• 2. South Bridge -it controls low speed devices
  like I/O ports, slots etc -it is placed nearer
  to the slots. -it is also called as IOCH (Input
  Output Controller Hub)

IDE / PATA and SATA Connector

• IDE (integrated drive electronics)/PATA(Parallel
  advance technology attachment)
• IDE/EIDE cables are used to connect the devices
  the connector
• It is 40 pins connector used to attached or
  connect hard disk, dvd r/w.
• SATA (Serial advanced Technology Attachment)
• SATA cables are used to connect the devices to
  the SATA
• It is pin less connector used to attached or
  connect hard disk, dvd r/w.
• FDD Port(Floppy disk Drive)
• It is 34 pin connector or port used to attached
  floppy disk drive.
