DMA:Direct Memory Access. A technique for transferring data from main memory to a device without passing it through the CPU. Computers that have DMA channels can transfer data to and from devices much more quickly than computers without a DMA channel. This is useful for making quick backups and for real-time applications. Some expansion boards, such as CD-ROM cards, are capable of accessing the computer
There is difference between SATA and PATA HDD but no difference between the formatting..
It depends. If it is a laptop hard disk, and you know the interface (IDE or SATA, there is a difference), you would purchase a 2.5" IDE/SATA Hard Disk Enclosure. If it is a desktop hard disk, and you know the interface (IDE or SATA, there is a difference), you would purchase a 3.5" IDE/SATA Hard Disk enclosure. Hopefully this helps.
Sata drives are usually faster.
SATA hard disks are basically hard drives or optical disk drives. The prices an SATA hard disk for them vary from $50 to $200. They can be found on a variety of websites online.
SATA and eSATA are electonically the same, but the construction of the cables and the terminals is different. The major difference between the two is that SATA is designed for use inside a computer system while eSATA is for use externally.
hard disk
A serial hard drive is the same as a SATA hard drive. SATA is Serial ATA, and PATA is Parallel ATA.
to make the computer function
Sata of course. It is much much better/faster/economical.
There are two types of Hard disk. 1:Sea gate disk 2:SATA Hard disk
1. IDE Hard Disk 2. SATA Hard Disk 3. SCSI Hard Disk 4. Ultra SCSI Hard Disk
IDE hard disk, SCSI hard disk, SATA hard disk, External hard disk, it is also differ by RPM speed for the HADD. I hope that helpes.
