There are magnetic, optical, and solid state storage devices. Floppy disks and hard drives are magnetic storage devices. If exposed to a magnet data loss may result. Hard drives have a 137 GB limit. You must flash the BIOS to upgrade it and it will allow it to support a larger number of hard drive addresses. The Hard drive interfaces to attach to the motherboard are PATA/IDE, SATA, SCSI, USB, and FireWire. Along with hard drives, parallel ATA (PATA) and serial ATA (SATA) are also used for CD drives

simultaneously. For memory, there is the Dual-channel DDR2 memory slots. The North Bridge is connected directly to the CPU. The South Bridge chip is responsible for handling the I/O functions. The SATA host adapter will let you connect an external hard drive for backup. One component that you may not see any more is the floppy drive controller. It is used to reading and writing to a computer’s floppy disk drive. By upgrading the motherboard alone will give some performance improvement to a computer
