Difference between ULTRA ATA and SERIAL ATA

Hello,
What is the difference between ULTRA ATA and SERIAL ATA ?? Is the connector different for each type ?? Thanks in advance.
Robert Lespérance

Was wondering why you are considering a ATA drive? The iMac G5 als has a serial ata drive already.
If you are considering an external drive, then you have a problem. The most important thing there is that you get a drive with firewire interface because I think they are the fastest, but USB is an ok choice. If there is an external firewire drive that also uses a serial ATA drive inside of it, then that would be an excellent choice for speed. USB or Firewire are standards for connecting a peripherial to you Mac. An external drive will probably have a very common, read Mactor, WD, Seagate, ATA drive in it. The external drive case has a interface inside of it which allows USB or Firewire to speak with the ATA drive, any flavor. Some people just purchase a powered external 3 1/2 case and install the hd they like the best, that is the nice thing about standards.
I think serial ATA will pretty much spell the end of all of the older ATA drives. The serial drives are actually very competitive in price now and faster.
Suggest you go to Western Digital, Maxtor, and/or Seagate's web sites to learn what drives they offer.

What instruments?
What type of instruments?
What does the manual for the instrument say about reading the serial no.
How are you communicating with them? Are they GPIB instruments? Are they DAQ instruments?
What do you mean by "2 parameter display" and "3 parameter display"?

Differences between SB Extigy and SB Live! 24 Exter

Hi,
I want to know what are the differences between SB Extigy and SB Li've! 24 External.
The Extigy seems to be older and i would say the SB Li've! is just the "new" Extigy (pardon me, bad english inside).
But the price difference was quite big, so is there another reason ?

one is built into the southbridge and has been proved to be faster because of this
the other is on a seperate chip
Serial ATA/150 controller integrated in VT8237.
- Up to 150MB/sec transfer speeds.
- Can connect up to two Serial ATA drives.
- Supports RAID 0 or RAID 1.
so sata drives only
Supports Ultra ATA, Serial ATA, Ultra ATA RAID 0 or 1 , Serial ATA RAID 0
or 1, Ultra/Serial ATA RAID 0+1 supported.
• Connect up to 2 Serial ATA devices and 2 Ultra ATA 133 devices
promise allows use of normal ide drives
promise will take a single drive the via one as ive read it seems to want 2 in raid 0

What is the difference between a full and a upgrade version?

When I want to buy photoshop elements 8.0 i can select a full or upgrade version, the price is alsmost thesame.
normally you would think a upgrade is just a upgrade and you can't use it if you don't already have photoshop Elements installed.
but in many online stores they only sell the upgrade version.
so that makes me believe you can buy it even tho you don't have any photoshop elements on your pc.
so what is the difference?

The only difference between the Upgrade and Full version is of the pricing. I believe right now Adobe is already offering PSE at $79 so there is no Upgrade option appearing on the website (although I am not sure about unavailability, I just stating what one of the user on the forum says).
Legally, you should be a previous customer of PSE to buy an upgrade version and I am not sure but I believe when one go for buying the Upgrade version they do need to provide the serial number of the previous verison.(not sure though)

MBA - difference between early 2014 and mid 2014?

Today my new MBA 13", 1.7, 8 GB, 256 GB has arrived. When I checked the serial number I found out, that it is from early 2014. Is there a difference between early 2014 and mid 2014?
Should I send it back to the reseller?

Thank you for the quick reply. I wonder about that because in German online shops and communities there is often written about mid 2014.
One the Apple homepage I found out the early 2014 works with Mavericks. The current MBA in the apple store works with yosemite. But I could not find and hardware differences...

What is the difference between handling unit and packaging material

hi
what is the difference between handling unit and packaging material

Hi,
A handling unit is a physical unit that consists of the packaging materials (load carrier / packaging material) and the goods contained therein. A handling unit is always a combination of materials and packaging materials. All the information contained in the material items, such as batches and serial numbers, is always available by way of the handling units.
Packaging materials are intended to enclose or hold together the materials that are to be packed. In other words, the material that is to be packed can be packed into or onto the packaging material. The packaging material can be a load carrier. The most important packaging materials include crates, boxes, containers, wire baskets, and pallets.

Finding difference between Max date and Min date from single date field

Dear Experts,
Here I am with a scenario where i didnt find any solution in SDN and in most threads it is unanswered.
I have 1 KF which is a date field. With reference to Serial no, I want to find out the Max and Min date from the same KF. I created 2 CKF where the same KF is used in both CKF to find the Min and Max dates,
Ex:
Serial No | Material | Actual Del date | Max | Min | Difference
0123 | 300012 | 01.01.2009 | 31.01.2009 | 01.01.2009 | 30
0123 | 300013 | 07.01.2009 | 31.01.2009 | 01.01.2009 | 30
0123 | 300018 | 15.01.2009 | 31.01.2009 | 01.01.2009 | 30
0123 | 300014 | 30.01.2009 | 31.01.2009 | 01.01.2009 | 30
0124 | 300019 | 02.01.2009 | 10.01.2009 | 02.01.2009 | 8
0124 | 300012 | 06.01.2009 | 10.01.2009 | 02.01.2009 | 8
0124 | 300017 | 10.01.2009 | 10.01.2009 | 02.01.2009 | 8
This is the way how I want the output where now I am able to get the values right till Max and Min and not the difference. I even created the 3rd CKF the find the difference but it is not working.
How can I find the difference between the Max and Min dates?
Regards,
Chan

Hi
You have FM --DAYS_BETWEEN_TWO_DATES you can use this while Customer Exit.
Try to Have 2 RKF for Min Data and Max Date and create a formula/CKF on the same ..
Hope it helps

Difference between SaxSource,DomSource and

Hi All,
I would like to know the difference between SaxSource,DomSource and
StreamSource.
And also at what Scenarios developer should use above instances. What
are the advantages/disadvantages of one Source Object over other two
source objects.
Thanks
Inidan

Hi,
SAX is typically used for large documents because it parses documents serially, in an event based fasion.
DOM is more memory intensive because it builds a tree model of the XML document within memory, and so should only be used for smaller XML documents.

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

The difference between chapter markers and dvd studio pro markers

Does anyone know what is the difference between chapter markers and dvd studio pro markers? I can not find anywhere on Google. Also in the tutorials I have seen, suggesting DVD Studio Pro markers, but it did not mention the chapter markers.
Thanks,

"Adding Chapter and Compression Markers to Your Sequence
Once you have your edited sequence or program finished, you can add markers to the sequence for use on DVD. Markers are reference points you can place within clips or sequences that identify specific frames. There are two kinds of markers you can add that directly relate to authoring a DVD—chapter markers and compression markers.
• Chapter markers allow DVD authoring applications to create a navigable chapter list for your exported QuickTime movie. Chapter markers force MPEG keyframes (known as I-frames) at their location, since the DVD specification requires an I-frame at each chapter point.
• Compression markers identify areas of abrupt change and include two types: those that are automatically inserted by Final Cut Pro at all edit points, and those you manually place in the clip or sequence. Like chapter markers, compression markers force I-frames at their location, although in this case it is for better quality encoding, and they are not used to create a chapter list.
Note: When you export a QuickTime movie, you have an option to export various kinds of markers, including compression, chapter, or DVD Studio Pro markers. *When you choose to export DVD Studio Pro markers, Final Cut Pro actually exports chapter markers and all compression markers.* This includes compression markers you set manually, as well as ones created automatically by Final Cut Pro at edit and transition points."
From the Final Cut Pro User Manual.

The difference between an iphone and an ipod touch?

i want to know if the difference between an iphone and an ipod touch is just that the iphone is like a phone that has internet and is a phone. or what else is it?

The iPhone includes the same as an iPod Touch but also includes a phone, a camera, and a GPS radio.
In addition to having internet access via wi-fi, the iPhone also has internet access via the cellular network, so as long as you have cellular reception with the iPhone, you have access to the internet in addition to having access via an available wi-fi network.

The difference between system restore and last good known configuration

hi,
what is the difference between system restore and last good known configuration.
in which situation you use system restore ,and in which situation you use last good known configuration.
very short answer wil be enough.
thanks
johan
h.david

Last Known Good Configuration deals only with Starting Windows eg. a bad registry or incorrect driver is preventing Windows to start.It recovers the registry settings of HKEY_LOCAL_MACHINE\System\CurrentControlSet
While System Restore uses restore points to return your system files and settings to an earlier point in time without affecting personal files. Restore points are created automatically every week, and just before significant system events, such as the installation
of a program or device driver. You can also create a restore point manually.You can undone system restore but there is no such option in Last Known Good Configuration.
Last Known Good Configuration is disabled in Windows 8 or,Windows 8.1 by default.
Try using Last Known Good Configuration if you can't start Windows, but it started correctly the last time you turned on the computer.
Try using System Restore to return the system to an earlier point in time when things worked correctly.
