harddisk is data stroage memory and three type of harddisk 1.ata 2.pata ...3. sata..

Hard disk is a secondary storage device. and permanent storage device also.There are many hard disk types. In those, ATA Hard disks, PATA Hard disks, SATA Had disks, USB Hard disks & SCSI Hard disks.

we have two types of hard disks
1. IDE Harddisk
2. SATA Harddisk

The harddisk drive in your system is the "data center" of the PC. It is here that all of your programs and data are stored.It is a permanent storage used in PC.

Types of Hard Disks

1) ATA - Advanced Technology Attachment
2) SATA - Serial ATA (Advanced Technology Attachment)
3) PATA - Parallel ATA (Advanced Technology Attachment)

Note:
1)The alphabets C-Z represents the partition of the hard
drive... not the types.

2) Primary master
Primary Slave
Secondary master
Secondary Slave

These are the connection types used to connect 2 Hard
Drives to a single IDE connector(using JUMPERS).
You can connect a single Hard Drive either as Primary
masterslave or Secondary masterslave...
(using JUMPER settings and choosing IDE connectors).

3)Number of Hard Drive connections depends on the Mother
Board...

Harddisk is non- volatile memory which store data.There are two types of harddisk ATA/IDE ,SATA and SCSI
ATA advance technology attachment

What is the harddisk and how many types of haddisk are there?

1. ide 2. sata

A hard disk drive (often shortened as hard disk, hard drive, or HDD) is a non-volatile storage device that stores digitally encoded data on ...

?SAS Serial Attached SCSI.
?SCSI Small Computer Systems Interface.
?SATA Serial ATA or Serial Advanced Technology Attachment.
?IDE Integrated/Intelligent Drive/Device Electronics.

harddisk is permanent storeage divice which in data safe for very long time .hdd coming very sizes acc. capacity such as 5.25″ FH 146 mm 47 GB[37] (1998) 14

There are a few ways in which a hard disk can connect/interface with:

* ATA (Advanced Technology Attachement/Also known as IDE, ATAPI and Parallel ATA)
* Serial ATA
* SCSI(Small Computer Systems Interface)

Hard Disk is parminent storage device. Hard Disk types are
1) ATA(Advanced Technology Attachments)
2) PATA(Parallerer Advanced Technology Attachments)
3)SATA(Serial Advanced Technology Attachments)
4) SCSI(Small Computer System Inteface)

hard disk is a permanentely storage divece where all the data and information store it is also called
non- volatile memory
there are five type
1 SATA 2 PATA 3 SCSI 4 USB 5 Wireless HDD

HDD is a secondary and permanent storage device,it consists several circular plates. ata100/133 MBps,sata600MBps,scsi it is very fast speed device u can connect up to 15 device on single port.
usb hdd it is external device.

harddisk is a parment storage deviece
it is a some many types of harddisk
IDE (integardated device electronics)
it is a 40 pins of aharddisk
sATA (searial advance technologies attctedment) it is 7pin using of aharddisk
pata (parral advance technologies attach ment)

Hard disk is secondry storage device. it is volatile memory storage device.normaly 3 types of HDD(HARD DISK DRIVE)
1)IDE(Intigrated elecctronic device)/1)PATA(Parallel advance tech.attachment.2)SATA(Serial advance tech.attachment 3)SCSI(Small computer system interface)
a)ATAPI(advance tech.attachment paacket interchange) B)SAS(serial attach.scsi) C)SASI(shugart associate system interface) 3 extra types of HDD.

hard disk is data storage centre data it''s mean all files and folders os permanently storage the disk
hdd are ide ata sata pata scsi pen drive
now a days every one usin the sata, pata,scsi.
