DMA (Direct Memory Access)
Direct Memory Access is a protocol for transferring data to and from main memory without
passing it through the processor.
DMA improves speed and efficiency by allowing processing to
continue while new data is retrieved from the drive.
Electrostatic Discharge
The rapid discharge of electricity caused by static buildup that can damage or destroy electronic
equipment.
FAT (File Allocation Table)
The File Allocation Table is a group of sectors in a partition containing a map to address chains
for files in a partition.
There are two FAT copies in a partition.
FAT16
FAT16 uses a 16-bit field to address clusters in a logical partition. FAT16 is limited to
approximately 2.1 gigabytes and 65000 clusters.
FAT16 is compatible with DOS, Windows 3.1,
3.11 and 95 A, Windows NT 3.5 and 4.0, and OS/2.
FAT32
FAT32 uses a 32-bit field to address clusters in a logical partition.
FAT32 allows partitions larger
than 2.1 gigabytes and provides millions of clusters.
FAT32 is compatible with Windows 95 SR2
and 98.
FDISK
FDISK is a DOS program used to partition a hard disk drive.
Format
A process that creates FAT tables for a partition.
Head
A head is an electromagnetic coil and metal pole that write and read back magnetic patterns on a
disk.
IDE (Integrated Drive Electronics)
IDE (also known as ATA) is the bus interface that replaced the controllers in original IBM
compatible PCs.
Interface Data Transfer Rate
The interface data transfer rate is the speed at which a hard disk drive transmits and receives
data from the interface.
Interrupt 13 and Interrupt 13 Extensions
Interrupt 13 is the BIOS program routine for handling hard disk commands and data.
The original
interrupt 13 BIOS program supported capacities up to 8.4 gigabytes.
Interrupt 13 extensions are
new BIOS routines added to support drive capacities greater than 8.4 gigabytes.
Jumpers
Jumpers are small pieces of plastic with a conductive center.
Jumpers connect pins on a hard
drive to set device options.
LBA (Logical Block Addressing)
Logical Block addressing is a mode of accessing a location on a hard disk drive.
LBA
sequentially numbers the sectors on a disk, eliminating the need to calculate the cylinder, head,
and sector coordinates of a data sector.
