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
Sata drives are usually faster.
There is difference between SATA and PATA HDD but no difference between the formatting..
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.
All of them are hard drives.
The difference between sata and IDe is that of Cable Connector that connect Hard disk to the motherboard, Sata Hard disk is a new technology and IDE is old, Sata is relatively fater to as of IDE, IDE cable differes from SATA cable, Toshiba has recently introduce its 5400 rpm Sata hard disk, the fastest sata hard disk in my knowledge is 7200 rpm by Seagette.
molex for IDE devices and sata power connector for SATA devices
how many types of hard disk drive are available... IDE, SATA, SCSI, SATA2, SAS
Serial ATA (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives.
There are numerous differences but an IDE or "PATA" hard disk uses a parallel method of transferring information, while a SATA drive uses a serial stream of information.
ATA = Advanced Technology Attachment and has speeds of up to 133 Mbps. Has a 40 pin connector. SATA = Serial ATA. Smaller connections and higher data speeds. See the attached link for a webpage with more info.The SATA host adapter is integrated into almost all modern computers. The difference is sata is 7 pin connectoe and ata is 40-44 pin
There are tons of kinds of drives. Floppy Disk Drives, CD-ROM drives, PATA Hard drives, zip drives, flash drives, DVD drives, SATA hard drives.... The list could go on and on and on...
Hard Disk that has Sata Cable and has a smaller jeck than normal Hard disk is called Sata Hard Disk
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.
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.
Yes, you can. If your computer has more sata ports you can use then to connect more hard drives.
IDE HARD DISK SCSI HARD DISK SATA HARD DISK EXTERNAL HARDDISK. IT IS ALSO DIFFER BY RPM SPEED FOR THE HADD.
A disk controller is used to control disk drives. Such a controller adds disk drive ports/connectors to a system, and in a format compatible with whatever specific drive type. A floppy controller would control a floppy drive, a SATA controller a SATA drive, etc.
this is strongly dependent on the type of "drive you are trying to connect" a ide hard disk "drive" as well as a floppy "drive" will use a ide ribbon cable connector a sata hard disk "drive" and newer cd/dvd, and ssd "drives" will use a sata connection (either rated at 3.0 gbps, 6.0 gbps or otherwise) you can also find other types of drives that are more along the range of enterprise grade server drives vs consumer grade such as SAS hard disk "drives" which are similar to sata hard disk "drives" except they spin at a exceptionally larger rpm and are faster however they use their own SAS connector.
IDE stands for "Integrated Drive Electronics". It's one of the older interfaces used for disk drives (particularly hard drives and CD drives). IDE isn't exactly "obsolete", but SATA (which can be faster) is more common nowadays. Some motherboards and drives have both IDE and SATA connectors.
SATA hard drives are hot swappable, meaning that you can can unplug it while the computer is on just like a flash disk. Make sure that the power is already connected, it is not recommended to plug in the power connector while the machine is powered on. The SATA data cable is plug and play.
Open the case and look at the hard disk drive. If it is connected with the gray (typically) 40 pin ribbon cable, it's IDE, if it uses the MUCH smaller SATA cable you'll be able to tell the difference.
This is a data ribbon cable is used for computer drives, like hard disk drives, Optical disk drives, and floppy disk drives. They are also referred to as PATA cables. They connect to parallel ports consisting of 20 pins in one row, and 19 in the second, for a total of 39 pins. IDE cables are now considered old, having been largely replaced by SATA cables, which connect to newer drives which run at more RPM. The SATA system communicates more quickly that the PATA system using IDE cables.
The difference between a drive and disk is that a drive is used to read a disk whether it be a floppy disk or a compact disk.
In some, no disk drives, most 1, lots 2 and in servers and workstations, up to 72 physical drives. Floppy disks, hard discs (IDE, SATA, SCSI, SSCSI, PATA, EIDE, ATA, MFM, RLL), solid state, zip drives, USB drives, and CDROM/DVD.
