In short, the difference between Serial ATA (SATA) and Parallel ATA (PATA) is how the computer communicates with the hard drive. * OK PATA is older technology that is still found in many computers. * OK Can I see this with lspci? It has a theoretical limit of 133 MB per second. Because the computer was communicating with the hard drive in parallel and because of the possibility of interference between the 80 wires used to connect PATA to a computer, a PATA cable can be a maximum of 45 cm long. The need for additional speed without the limitations of parallel communication and possible interference drove the designers to come up with a new standard which turned out to be SATA. Note: of the 80 wires in PATA, only 40 are actually used. The other unused wires help with the interference issue. * Pata and sata are description of the hardware? A SATA device uses only 7 wires for the interface cable. Just getting rid of all of those wires helps tremendously. SATA comes in three speeds: SATA 1 is limited to 150 MB/s SATA 2 is limited to 300 MB/s SATA 3 is limited to 600 MB/s Cables are limited to 1 meter. With SATA came an additional standard called eSATA which is meant to convey "external SATA." These devices are used for things such as external hard drives where you don't want to pay a performance penalty. Because these are designed to run to external devices, the specification for the cables is much stricter. Better wire sheilding is required. The limit for eSATA cables is 2 meters. * OK Most computers manufactured in the last 5 years offer 2 to 4 or more SATA connectors. Many offer at most 1 PATA connector and many no longer offer PATA connectors at all. <snip> * Where is it important to know this pc is sata that pc is pata? > I take the line where "Mounted on" is /.

You can think of the "/" partition as the operating system. * OK This is an oversimplification but will work for now. * OK When you select Xubuntu from the grub menu, The Xubuntu operating system is loaded with / * Like a root? also known as the root file system being mapped to /dev/sda6 in your case. All that means is the first SD drive (a) and the 6th partition (6) on that drive. * OK <snip> > > /dev/hd* is for IDE or ATA devices.* > This I dont understand. It is just a standard developed by the creators of Linux. They refered to PATA (also known as IDE and ATA and ATAPI) drives using the two characters "hd" I think meaning harddisk device. So the first PATA hard drive would be /dev/hda. The partition number is then added after the drive. The third partition on the first PATA drive would be /dev/hda3. <snip> > For example, on your system, Xubuntu's / is on partition > 6 listed as /dev/sda6. > * > Is that the operatin system? > Yes, but as I mentioned above when you get to know a bit more about Linux you will realize this is an over simplification. * OK > <snip> > I started out keeping everything Linux > under a single partition.

I assume you are running Xubuntu 12.04 or 12.10.* I am using now 13.04 and I do not know why I updated and there there is 13.04. It is my mistake. When 13.04 comes out in April this year you will have the opportunity but NOT the requirement to upgrade to the new version. * Question. I was reading I have to upgrade. Why. There is an upgrade from Pangolin to Quantal but there is no update from Hardy to Pangolin because it is said only one step is possible. Is this wrong? Xubuntu may have the option of upgrading in place which means the OS will present you with the ability to get the new version without a complete reinstallation. * Is upgrade an new install? Change the partition. Any time you take a section of a hard drive and modify that section by shrinking its size, expanding its size, or installing a completely different OS or OS version on it. * OK Thank You.
