  50. Northbridge
    the Northbridge is the chip, or collection of chips, that connect a Central Processing Unit (CPU) to memory,  (PCI) bus, Level 2 (L2) cache and (AGP) activities.
  51. The Northbridge chip communicates with the CPU through the x
    Frontside Bus (FSB)
  52. Connects CPU -> RAM/PCI/L2 Cache/AGP
  53. The Northbridge can consist of x unlike the Southbridge which is typically only y
    • Northbridge: multiple chips (possibly)
    • Southbridge: 1 chip
    • PATA/IDE:
    • 40 pins
    • 1st pin marked by red wire
    • Originally supported 16MB/s
  54. Later standard of PATA allowed for x connections
    80 (2 per pin), allows for faster transfer rate
  55. Mainboards normally have x PATA connections available, and support y devices on each connection.
    2, 2
  56.  Later versions of PATA increased the speed to x
    33, 66, 100, 133 MB/s

  58. SATA throughput range
    1.5 GBps (192 MBps) - 6GBps
  59. SCSI
    SCSI, or Small Computer System Interface, is a standard for attaching multiple devices onto a single connection chain. It normally allows 7 or 15 devices depending on the standard (not counting the SCSI controller itself.) It is mostly used in servers.
  60. SCSI connection chains must be terminated - otherwise you will have undesirable interference preventing the devices from working.
  61. Standard for floppy discs
    • 3 1/2"
    • 1.44Mb
  62. Southbridge
    Southbridge is a chipset that manages the basic forms of input/output ( I/O ) such as ( USB ), serial, audio, Integrated Drive Electronics ( IDE ), and Industry Standard Architecture ( ISA ) I/O in a computer. 
  63. Industry Standard Architecture (ISA)
    • This architecture was originally used in the IBM PC/XT and PC/AT used for connecting peripheral devices. It has been made obsolete by PCI.

  64. ISA ports (3 black)
  65. ISA supports up to
    16 devices
  66. Accelerated Graphics Port (AGP)
    • A standard for 3-D graphic interfaces. Its first incarnation had a bandwidth of 266MBps with 2x, 4x, and 8x versions later following.
    • Being made obsolete by PCIe
  67. Control Bus:
    The physical connections that carry control information between the CPU and other devices within the compute
  68. Is SRAM faster than DRAM?
  69. Interrupt Requests (IRQ)
    Interrupt Requests (IRQ) are hardware lines which devices can send interrupt signals to the CPU.
  70. IRQ0
    The reserved interrupt for the internal system timer. Used exclusively for internal operations and is not available to peripherals or other devices. A conflict on this interrupt would indicate a hardware problem on the system board.
  71. IRQ1
     This interrupt is used only for the keyboard/keyboard controller. A conflict on this interrupt would indicate a hardware problem on the system board.
  72. IRQ2
    • This interrupt is a cascade for IRQs 8 to 15, allowing the use of extra IRQs 8 to 15.
    • Conflicts on this line come from trying to use a device on IRQ2 and another on IRQ9 at the same time
  73. IRQ3
    This interrupt is used for COM2 and COM4 (second serial port and fourth serial port). It is a popular option for modems and sound cards.
  74. ATX Motherboard (1995)
