IMac applications/data transfer

I just unpacked and activated my new iMac and wish to transfer to this new iMac all of my applications and data files that are imbedded in my old eMac, including Quicken 2004 for Mac, Adobe Photoshop CS2, Adobe Bridge, iWork'08 and Apple Works 6. Since I don't have a firewire cable with an 400 Mb/sec plug on one end and a 800 MB/sec plug at the other end I am unable to use the Setup assistant to help me in transferring my applications. Can I use an Ethernet cable to accomplish this transfer. Also, must I install OS X 10.4.11 in my new iMac in order to run some of the older applications like Quicken and Apple Works? Any help will be greatly appreciated by this old (81 ys) man.

Hmmm, not a good idea. Most of your applications are too old to work. You will need to locate and download upgrades to Leopard compatible versions where available. This includes replacing CS2 apps with CS3 or CS4 (preferably the latter) versions. Not sure that Quicken has a compatible version but you can check Intuit's site. You may need to find a replacement such as Tax Cut. Replace AppleWorks with iWork '09, although iWork '08 will work. If you plan to continue using AppleWorks you will need to download the AppleWorks 6.2.7 OS X version. It may continue to work tolerably with Leopard.
You cannot install Tiger on the new iMac. Don't even try.
You can connect the two computers vis Ethernet or if you have a home network both computers could be connected to your router either by Ethernet or wirelessly if the router supports wireless. Select Mac Help from the Finder's Help menu and search for "sharing" or "file sharing" for help with this. However, for your personal data files you may find it's easier to transfer them to a USB flash drive then copy them from the flash drive. Alternatively, backup the hard drive on your eMac to an external FireWire or USB drive in order to transfer your files.
Be careful about what your chose to transfer because there's a world of difference between a PPC and an Intel Mac as well as between Tiger and Leopard. See the following:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior 4.1, TechTool Pro 4.6.1, SuperDuper 2.5, and Drive Genius 2.0.2 work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking
will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Target Disk Mode.
5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
1. Set up a local home network: Creating a small Ethernet Network.
2. If you have a MacBook Air or Late 2008 MacBook see the following:

Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/ (copy the whole folder)
/Home /Library/Calendars (copy the whole folder)
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist

For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
Credit goes to Macjack for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

  • Possible network issues preventing successful application data transfer?

    Hello all.
    We are having a few issues with a specific set up here at work involving Oracle 11, and Oracle 9 databases and I was hoping someone with a fair idea of how Oracle configurations work when it comes to network connectivity and data transfer would mind sharing their opinion on the matter.
    First off, a bit of background. I'm a network security engineer by trade and my experience when it comes to the application side of things, specifically databases is inherently weak; so I apologise if my terminology or logic is slightly off here.
    Basically what I'm trying to determine is where a fault lies between our users using a terminal server and a remote Oracle SQL database that should service their requests.
    The problem lies wherein the user will utilise the 'sqlplus' application invoked from a Windows command prompt window, and expect to be able login and query a database. I believe we have two versions available to use, version 9 which is not actually in production but able to be used for testing and version 11 which is active in production.
    When accessing Oracle 11 servers will hang where we expect to see a successful connection followed by a healthy looking "SQL>" prompt data transfer appears to stall as follows:
    C:\>sqlplus username/[email protected]
    SQL*Plus: Release 10.2.0.1.0 - Production on Wed Sep 22 18:12:17 2010
    Copyright (c) 1982, 2005, Oracle.  All rights reserved.
    *hangs here*If we try on the Oracle 9 setup things look fine initially:
    C:\>sqlplus username/[email protected]
    SQL*Plus: Release 10.2.0.1.0 - Production on Wed Sep 22 18:19:20 2010
    Copyright (c) 1982, 2005, Oracle.  All rights reserved.
    Connected to:
    Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production
    With the Partitioning, OLAP and Oracle Data Mining options
    JServer Release 9.2.0.6.0 - ProductionHowever once connected to the Oracle 9 box; if we run a query similar to:
    sqlplus username/[email protected]
    select * from <database> where rownum < 10;This will again hang.
    That said however, if we try and run a query similar to:
    sqlplus username/[email protected]
    select * from <database> where rownum < 5;This will return 4 rows of usable data, without issue.
    Our systems engineer provided me with a SQLNET trace from the server side and believes he's identified where it occurs:

    #    Need to <CTRL C> twice to kill
    #I've tried searching the net for similar occurrences of some of the interesting looking trace data but there appears to be limited information available, none of which is terribly helpful.
    What I'm really after is either someone who has had this issue before, or someone who can better interpret the error output from the trace files and perhaps give me an idea of what's causing it to occur. Specifically whether that error text above relates to a failed connection on the underlying network connectivity side of things or whether it may be something on a higher level within the application layers. We have done packet dumps on firewalls to check the traffic as it traverses the firewall but there are no anomalies that I can see which may be contributing to the issue at hand.
    I have organised for some testing to occur within the next 24 hours as there is a Cisco ASA Firewall that sits in the network path that is performing inspection on packets travelling through it. The inspection for SQLNET specifically is disabled, but we intend to enable this once more for testing to see whether it makes a difference. I'm not entirely confident it will however, and until we do get a chance to test any constructive input or alternate ideas will be greatly appreciated. I'm trying to cover as many bases as possible here.
    Cheers,
    Josh.

I can get the Oracle 9 queries to hang if I select over 7 rows (8 being the point at which it dies).
    So I can run
    Sqlplus user/[email protected]
    Select * from <blah> where rownum < 7;Over and over again, as many times as I like without issue.
    But!.. As soon as I run
    Sqlplus user/[email protected]
    Select * from <blah> where rownum < 8;The session will hang, and from a network perspective there are no packets being transferred in either direction. It looks exactly like the Oracle 11 session in that the session is still ESTABLISHED from a client perspective but no data is flowing in either direction..
    Does anyone have any idea why '8' is the magic number that would be causing it to hang? I'm really stuggling to see from a network perspective how this may be occuring, as above the TCPDump looks clean.
    Unfortunately I don't have access do a dump on the client/server itself however, just on the network path. I guess that may be where we need to be looking next.
    Thanks for the ideas so far all, much appreciated.

  • What is the best way to shut down an iMac that has frozen during a data transfer? The disk I was writing to will not eject. Stopping "copy items to" doesn't work either_ it is frozen as well. Is there a way to force eject the disk so I can shut down?

    Some more information on the above: OS: 7.2
    1. None of the shutdown commands would work so I held the power button down and received a prompt that asked if I wished to force eject the drive, I selected
    the force eject and then shut down.
    2. Just recently I installed an eSATA _ Thunderbolt_ port multiplier compliant PCIe card (Seritek Q6G) into a thunderbolt external chassis (OWC Helios) (seritek Q6G).
    This freeze data transfer also happened when I connected a Firmtek 5PM external tower to the iMac via thunderbolt cable.
    The driver for the seritek Q6G was installed in the iMac previous to connection of any of the devices.
    Both external towers mount ok on the iMac but have frozen during data transfer.
    The initial freeze was with the Firmtek 5PM which is (JBOD)_ I thought that might have had something to do with the freeze_ it being JBOD_ so next I tried the Mercury Elite AL Pro Q2- which is formated in RAID 5. But then froze too.
    Anybody have any experience with this?
    Maybe I need another driver?
    Or maybe some update to my OS?
    Any suggestions welcomed.
    Thank you

    Hello BDAqua, thanx for the suggestions. Before I saw this reply I tried to first quit the finder and then to relaunch the Finder but that resulted was a blank gray screen.
    In the end I ended up having to power down the iMac.
    Fortunately the RAID array that was "active" seems to be fine and also has a firewire 800 connection so I can use it_ just not with thunderbolt until this issue is solved.
    I'm going to check in the Applications>Utilities>system log to see if any clues are evident_ thank you for the suggestion.
    PS: Nothing of note was obvious as a root cause in the Activity Monitor though.
    hmmm....I was told that the Helios and seritek card were compatable and that the Helios didn't require any drivers..it will be a drag if there isn't an easy fix for this since this new PCIe card from seritek is the first to offer port multiplier compatibility for eSATA to thunderbolt...since they are both new I'm hoping that an OS upgrade will be the fix (presently7.2)...we shall see.

  • Problems with Photoshop performance and data transfer speed on iMac

    Two months ago, I started noticing slow performances using Photoshop (above all using clone stamp tool) on my 27" iMac (late 2012). I did the AHT and I found that 8GB of 32GB RAM were broken.
    I removed them but the problem didn't disappered, I also noticed that data transfer speed (both copy and paste from/to internal HD and from CF card/external HD) was really slow.
    I tried many solutions suggested by Apple support, none of them worked out. At the end, I tried uninstalling and re-installing Photoshop: no more problems!!!
    10 days ago, I received a new 8GB RAM module and so I installed it back... suddenly, the problem came back, I tried re-installing again Photoshop but the problem, this time, still persist!
    Does anyone had the same experience? All other CC programs work well (LR, AE, Premiere...)

    yes, it does!
    what seems to be very strange to me is how data trasnfer speed could be affected!
    (just to say, I've already tried reset of SMC and PRAM, I've tried with different accounts and I've also re-installed the OS, next step would be formatting the disk and installing the OS from zero)

    m1doc,
    Are you migrating from a Mac or a MS Window machine? Either way you probably should be in touch with AppleCare, you have 90 days of free AppleCare telephone support. They can usually help on issues like this. If you don't know the phone number please use http://support.apple.com/kb/HE57 to help find the number in your country.

  • Disk data transfer rate - iMac 2013

    Good morning Apple fellows
    First of all, sorry for my troubled English speaking, I'll do my best to explain the issue I'm having in the best way possible.
    Yesterday I finally received my new iMac (I'm a proud Apple user since 2006), the machine has these specifications: 16 GB Ram, i7 processor, nVidia GT 780M, and a SSD drive of 1TB of capacity.
    Under Mavericks everything runs smooth and fine, no issues at all, just perfect, the fastest machine I've ever had. Unfortunately, I had to install Windows 7 via Bootcamp (I'm a mechanical engineer and I use Autodesk Inventor to do my stuff).
    After completing the installation of the Microsoft OS, I instantly noticed some laggy performance while running Windows: I installed as asked all the Bootcamp drivers with the USB pendrive that I prepared, but both the startup of the system and the normal use were a bit slow, even slower than my old '09 iMac.
    In order to understand what the problem was, I ran the system performance test included in Windows: all the ratings I have are maxed out at 7.9 (7.9 is the top I think), in exception of the "Disk Data Transfer Rate", that is 5.9. As far as I remember, this value is typical for a mechanical disk drive, not for an SSD drive supported with PCIe connections.
    Does anybody here got a similar issue? Is there any driver package that I have to install in addition to the Bootcamp drivers?
    Thanks in advance

    That is because the WEI uses your boot disk as the default device to measure performance, and, for instance, a Velociraptor 10 K disk, does not score more than 5.9. The story changes when the test is run on other disks, like my array:
    However, this measurement is totally worthless in real life. You should look at practical benchmarks like PPBM5 Benchmark

  • Data Transfer / Communication between Live Applications

    Gurus,
    I am basically an E-Business Sutie Developer. This is my first experience posting questions in Application and Architecture community.
    Please read the following and let me know if this is the correct thread to post this question also it would be appreciable if you could provide suggestions / solutions for my question.
    Q:
    We are on E-Bus Suite 11.5.9 with custom applications built using Oracle Forms. Recently one of our department decided to buy a custom software to replace one of the application. There are other applications which we built still running in E-Bus Suite. The custom software is based on .NET and SQL Server. We at IT rite now researching how to data transfer between our existing applications and the new software. They both were in different platforms.
    This is a new initiative for us because all these years we use to work on oracle applications and this is the first time where we have to go away from our forte. This could be simple for people with experience in related field but this is challenging for us.
    Your views and suggestions are highly valuable.
    Thank You.
    Karthik.

    Hi,
    Thank You for the reply. Below are the notes from person who already did some of the research. I am not sure whether to go with the below mentioned or to research more...
    Below are the following options to load data from SQL server to Oracle, I read limited on each option. See if something convince you and I will explore more on that option..
    1.     Linked Servers: Linked Servers can be setup on the SQL server instance and then data can be pushed out to the Oracle schema.
    a. Limitation in terms of data type supported by provider/ODBC driver used for creating
    linked servers, Performance good for decent size tables
    b. Advantage: All SLQ based
    http://msdn.microsoft.com/en-us/library/ms188279.aspx
    http://www.codeproject.com/Articles/35943/How-to-Config-Linked-Servers-in-a-Minute
    2.     Oracle Hetereogeneous services: This is Oracle’s answer to Microsoft’s linked servers. By setting it up,
    this can be used to pull data from SQL server db and load to Oracle.
    Same limitations and advantages as 1.
    http://www.csee.umbc.edu/portal/help/oracle8/server.815/a67784/hs_ch6.htm
    3.     DTS (Data Trnasformation Services) or SSIS (SQL Server Integration Services) : Microsoft SQL server 2000 comes
    with DTS and SQL 2005 with SSIS.
    SSIS is robust than DTS for this job and can be used to load data up in the Oracle Schema.
    These tools can be used to provide a real ETL process for data loading.
    4.     Scripting Framework: Scripts can be written to bcp data from a SQL servere db and then use SQL Loader to
    load data to oracle schema
    5.     Third Party tools: A couple of third party tools also provide these options.

  • Problems with data transfer iMac to imac

    I am transferring information from a 2008 iMac to a new 2014 iMac using an ethernet cable and a thunderbolt/ethernet adaptor. It has taken over 21 hours so far. Is this normal? At the Apple store they suggested it would take around 6.
    The new iMac has a screen saying 'Transferring your information' and a moving stripy blue and white line which is presumably to reassure me that something is happening - it isn't!
    I followed the instruction on the Apple website. Since then, I have read that one should turn off wifi on both computers before using Migration Assistant (I didn't because that wasn't in the directions).  I can't access the new computer but have turned off the wifi on the old one.
    There is about 319 gb data on the old computer.
    What shall I do? I need to be able to use the computer for work tomorrow.
    How can I stop the data transfer? There is no obvious means of doing so, there is also no information of how long it would take or how long might be left
    Thank you

    As Woodmeister50 told, direct connect between two iMacs via Ethernet cable is much faster than via adaptor, I suppose.

  • Moving thunderbird withEasy Transfer wizard but no Application data in list

    Hi
    Im using the easy transfer wizard as suggested. I have saved all my old computer files and settings to zip drive. Started the wizard on the new computer hit thr customise button undef my account nsme then the advanced button on he next screen but there is no file called Application DATA

    re; Im using the easy transfer wizard as suggested.
    Perhaps this was suggested by Windows to copy Windows files and folders, but I've not seen this advised to copy other program data that is stored in the hidden files and folders under 'Appdata' or 'Application Data' as this is where Thunderbird Profile data is located.
    If you are looking for a way to backup Thunderbid Profile:
    You can manually copy the Profile folder.
    you would need to make hidden files and folders visible:

    This opens a new window showing you Profile files and folders.
    Go up the directory to see the Profiles folder which contains your Profile name.
    or
    navigate to:
    C:\Users\Windows user name\AppData\Roaming\Thunderbird\Profiles\Profile name\
    Copy the 'Profiles' folder and the 'profiles.ini' file

  • Low data transfer between my iMac & Time Capsule

    Hello,
    I have just purchased 1GB Time Capsule yesterday to get a back-up of my iMac HDD, and also to use it as an external HDD. I was much interested by the wireless functions.
    After the installation, Time Machine started to save a back-up of my HDD (more than 200GB). But after one full night, only 7GB out of 220GB was transfered wireless.
    With a so low data transfer, it will take 20 days for the full back-up.
    Is it normal ?
    Do I have to make the first back-up though ethernet (wired) ?
    I am working on big video files (xx GB), so I really need to increase the speed of data transfer. Is there someting to change in the settings ?
    Thank you for your help, it will be highly appreciated...

  • Can I use gps applications like tomtom at the ipad mini with mobile data transfer turned off?

    Need help about ipad mini.
    The information on the apple web page refers that only the 3G versions have gps capabilities.
    Wath is not clear to me is if the gps works only when coneted with 3G data transfer, or it works without it, if I download some software like tomtom or navigon.
    Best regards
    Pedro

    You can use it without being connected to 3G. Only the 3G/4G iPads have a built-in GPS chip, the wifi-only models don't, and you can use apps such as TomTom with it which contain the maps, you don't need to be connected to 3G (or even have activated 3G on the iPad) or wifi to then use it.

  • Data Transfer to NEW computer--how to??

    Hello all!!
    Received just today a new Powerbook and was about to start the transfer of data and other "stuff" from my old computer (800 MHz flat-panel iMac) to the new computer.
    With regard to APPLICATIONS, as I have been told before, I will be installing any applications FRESH on the new computer and will set the preferences and other information as needed once installed.
    With regard to other "regular DATA"...Word files, MP3 files, text files, PDFs, image files, etc...the NON-application/NON-system files. Is there a special way that I should go about with the data transfer other than simply hooking p the computers via Firewire and dragging the data files to the new location on the new computer?
    The amount of data I will be transferring will probably be in the range of 10 to 20 GB.
    Also, while I'm doing this data transfer...before, during or after...once I have transfer this information to the new computer file locations, should I be doing a permissions repair or defrag or other "cleanup" operation??
    Thanks for your help!!

    Hi, Scott. The time to make sure both your Macs are in perfect order is before you transfer your files. On each Mac, boot to your OS installer CD or DVD and Repair Disk, repeating the routine until you get two successive "Appears OK" verdicts. Then reboot to your hard drive and Repair Permissions. Then use the Terminal or MacJanitor to force the daily, weekly and monthly background maintenance tasks to be performed. These steps should assure that your data and your HD directories are in good shape before you transfer your files.
    It can't hurt to repair permissions again on the new drive after you copy the files to it, but it probably isn't really necessary. Be sure to copy them to the same places on your new PB's HD that they occupied on the old one, if the same OS version and applications will be installed on both machines.
    Nothing that you copy will be fragmented after it arrives on the new machine, and Tiger will take care of most fragmentation that occurs later without needing any help from you.

  • Bottleneck in Data Transfer

    We run a small network in our office consisting mainly of Intel iMacs we purchased several months ago. The server computer is a brand new Intel Mac Pro server with 4 500 gig drives raided together, two 2.66GHz dual core intel processors, all the other bells and whistles we could think of, etc. We added in two fiber-optic switches: one in the server room, one in the office. The switches connect to each other and the server with fiber optic cables, but the iMacs connect with ethernet cables.
    We had the iMacs for a while but we just recently got the new server and upgraded our old 100 base switches. Afterwards we wanted to test out the data transfer speeds, as we plan to back up to the server frequently. We were dismayed to find that transfer rates capped out at 60 MegaBytes/sec according to the Activity Monitor's Network Activity tab. In fact, it would range mostly from 40-45MB/sec. None of us here have much experience with networking, but that seemed a tad too slow. My basic math tells me that a byte is 8 bits, and from that a Gigabit network should transfer data at 120 MegaBytes/sec, which is three times the speeds we were actually seeing.
    We sent data both to and from the server in order to test this. Thinking it was perhaps a problem with the ethernet itself, we grabbed an external FireWire hard drive and transferred data from one of the iMacs directly to it and noticed exactly the same transfer rates. We plugged two iMacs directly into each other and transferred at the same rate, ~45MB/sec.
    Well this was highly frustrating. All Macs supposedly ship with Gigabit ethernet since, what, 2002? Earlier? Why are our speeds so slow? We thought the hard drives might be slow, so we got info on the drives and googled them for their tech specs. The iMacs' Western Digital drives are capable of much much faster speeds according to everything we've read.
    We started reading anything we could online that addressed this issue. Some information read the problem might be that the optical DVD-R/CD-R drive was only capable of slower transfer speeds. Since the optical drive and the hard drive are on the same bus it would slow down the hard drive's maximum transfer rate, much like having a Gigabit hub with a 10 base computer plugged into it would slow the entire network down (which is of course why we use switches instead of hubs). Is there any truth to this? If this is, in fact, the case, can we bypass this bottleneck somehow? I'm not talking about opening the computer and manually disabling the optical drive, as that's a waste of a perfectly good DVD-R/CD-R drive.
    Also, if this is true, why in blue blazes is Apple flaunting Gigabit ethernet if the computer can only take advantage of 1/3 the speeds Gigabit ethernet has to offer?! I'll happily provide any more information that's relevant to the problem at hand.
    Thank you
      Mac OS X (10.4.8)  

    Here's the specs for the default Hard Drive that Apple put in here:
    http://www.westerndigital.com/en/products/Products.asp?DriveID=137
    From that page
    Buffer To Host (Serial ATA) 300 MB/s (Max)
    Buffer To Disk 748 Mbits/s (Max)
    I have no idea what signaling overhead for my data transfer protocol means.
    The ethernet cords are no longer than 20 feet, are all Cat5E, and are well shielded. There is little to no ElectroMagnetic interference in any area they run. The longest cable is the Fiber Optic one, which runs about... oh... 40 yards? These were all installed by professionals.
    I feel it's important to stress the fact that we tested an isolated direct computer to computer transfer with a single 6 foot Cat5E Ethernet cable and still experienced the same speeds that we experienced over the network. We tested multiple computers, multiple cables, multiple files.
