Can any hard drive be used with a DDR mother board?
As long as the type of HD (PATA or SATA) is supported, it will work. Old RLL or MFM drives will need a separate controller card.
What connects with a ribbon cable?
A 34-pin ribbon cable will connect a floppy drive.A 40 (or 80) conductor ribbon cable is for (E)IDE devices.Other ribbon cables may be used (80 conductor for SCSI, and in older systems, MFM and RLL Hard drives).A smaller ribbon cable (10 conductors) may be used for USB Headers.I think that covers most of them.
What are some 8 letter words with the 5th letter r 6th letter I 7 the letter l?
There are no 8 letter words in the English language that include letters RLL as the 5th, 6th and 7th letters.
On a 2002 Kia Sedona got a 456 code which means a loose gas cap Had replaced a locking cap with original a week before the check engine light came on Cap seems tight why won't the light go out?
well u might of fix the problem but u did not erase the code from the on board computer. do do so you can buy a obd 2 scanner or go to your local garage and get them to erase it. 04/12/2010 Our 2007 Sorento bought July 2007, went until now (04/2010) with an after market locking gas cap . It is now showing code 456. Replaced with original gas cap and code went away. When we bought the vehicle the parts manager said the Kias were sensitive to locking gas caps. Guess we were lucky to get a couple of years rll phx AZ
What standard is also called parallel ata?
Parallel ATA (sometimes called PATA) is synonymous with IDE or EIDE (Integrated Drive Electronics or Enhance Integrated Drive Electronics). IDE was the first technology to include the controller and hard drive in the same housing; previously with SCSI, MFM and RLL drives, the drive and the controller were separate.
What existed before ATA drives?
Before IDE/ATA drives, there were about 4-5 other types of drives.For PC XT/AT computers, the first used were MFM or "modified frequency modulation." They required a separate controller card, a power cable, a control cable, and a data cable. The controller could operate up to two drives. Common sizes were 10 and 20 megabytes.Then there were RLL (Run Length Limited) drives . RLL was very similar to MFM and used all the same signals and connections as MFM drives. In fact, most MFM drives could be used with RLL controllers. However, it was stored in a more compressed manner. So the same parameters of drives as MFM could contain 50% more data. So common drive sizes were 15 and 31 megabytes, though there were some larger sizes.Then there were ESDI (Enhanced Small Disk Interface) and SCSI (Small Computer System Interface) drives. SCSI drives are still used, though most now use a SATA interface, though with a modified command set from SATA, and are known as SAS (SCSI Attached Storage).Then came the ARLL (Advanced Run Length Limited) format standard. It was similar to RLL, but even tighter, and with Zoned Bit Recording, meaning that more data is placed on the larger cylinders. Before that, data was recorded with the same amount of data on every cylinder regardless of the location on the platter. There were other improvements such as less space used for addressing, integrated drive controllers, and faster speed. They were known as IDE because they had "integrated drive electronics." The interface standard was known as ATA or "Advanced Technology Attachment."ATA went though a couple of modifications. The ATAPI standard was developed for devices other than hard drives, including CD ROMs, DVD drives, and perhaps even cameras and scanners.Then there was SATA. That was because Ultra DMA IDE drives could not go past 133 MB/s because of the cabling. To reliably get past 33 MB/s, 80 wires were used, with a ground wire between all of the original 40 wires. That reduced crosstalk. However, that problem would return if they tried to go past 133 MB/s. So they changed to a serial data encoding scheme and clocked it at 10 times the data speed. That enabled 150 MB/s. Now the interface operates at quadruple that speed, giving 600 MB/s.There is also SAS as mentioned earlier. It is used mostly for servers. It uses a command set similar to SCSI but is electrically compatible with SATA. There is only one-way compatibility in that a SATA drive can be connected to a SAS interface with full compatibility, but a SAS drive cannot work with a SATA controller. Like the latest generation of SATA, the maximum interface speed is 600 MB/s.
What inventions do you think were integral in the development of modern computer?
A number of inventions were necessary for the development of modern computers. Here are some of them:The transistor - The first transistor was actually made in Canada. Then, months later, another type of transistor was invented by the Bell Labs team in the US, under the direction of William Shockley. For most applications, the transistor replaced the vacuum tube. This helped make modern computers because vacuum tubes were large, stayed hot, and consumed lots of power. The first electronic computer took up to 7 large rooms. Some rumor that it is now only used to heat the Smithsonian Building. But the invention of the transistor greatly reduced the size of the computers that could be produced back then and paved the way for integrated circuits.Very Large Scale Integration - Lynn Conway came up with some design rules that would help simplify the creation of large scale integrated circuit designs. Her colleagues took some time before taking her ideas seriously, not just because of possible sexism or transphobia, but because IC fabrication was (and still is) a very expensive process. They were impressed at how well her ideas simplified the process and gave them more room to work with on the die. So this discovery led to even smaller integrated circuits and the ability to cram more stuff into an IC.Storage technologies - Modern computers would not be possible without hard drives. IBM was among the first to create computer hard drives. About 3 to 5 megabytes was considered a lot, and 10 to 31 Mb hard drives were common in new IBM PCs. They started with FM encoding, then MFM encoding, then RLL and SCSI, and now SATA and SAS. Interestingly, MFM and RLL hard drives were roughly the same, though RLL drives were built to tighter technical specs. The electrical connectors were all the same and carried all the same signals and voltages. The main difference was in the controller board, which was a separate board then. And yes, many people did reformat MFM drives using RLL controllers, and while not the most reliable arrangement, it worked. IDE (close cousin to SATA) drives actually used a variation of the RLL compression scheme, and they added Zoned-Bit Recording, which means different numbers of sectors exist on different tracks. A downside was that end users could not redo the low-level formatting. SATA built upon that by changing how the data was sent to the bus, but was otherwise IDE compatible, making adapters between them possible.Display technologies - Laptops were designed mainly because computer scientists wanted to be able to do their work anywhere. In the process, LCD and LED monitors were created. Oh, there were portable computers with CRTs, but they were still bulky and heavy. The LCD technology had a lot to be desired for years. It was grainy and would "bleed," but it was usable. As more were produced, the better the designs became. Then it reached a point where decent LED and LCD monitors were feasible enough to use for making televisions and desktop monitors. This also paved the way for "all-in-one" desktops
What is the hard drive controller on a circuit board inside th edrive house?
With the advent of IDE (Integrated Drive Electronics), manufacturers started including the drive controller in the same housing as the hard drive itself. This made for faster access times as well as fewer issues with moving a drive from one controller to another (as with MFM, RLL, and SCSI drives) The controller acts as an interpreter, getting requests from the computer and taking control of physically moving the drive heads, controlling the spindle speed, self-diagnosis (S.M.A.R.T.) and so forth.
How many disk drive are there in a computer and what are there?
As many as needed. In laptops/notebooks there is usually only one hard disk. In a desktop or server there could be potentially any number of disk drives. If you mean a CD/DVD drive the same applies.
What is the difference between magnetic media and optical media?
Optical media is written and read on disks with lasers, such as a CD-Roms, BluRays, and DVDs. Magnetic media is written and read with magnets (like your hard drive and a floppy disks (which are almost non-existant anymore)).
