Primary partition:
you can install additional Operating system (eg:- windows 8, linux etc.)
Logical Partition:
Just additional drive which can be used to store additional data/ normal files/ software.
what are the advantages and disadvantages primary cells?
primary, extended, logical - 3 types
in Linux this is the second logical drive inthe extended partition on the primary slave hard drive
Create one primary partition and an extended partition with four logical drives within it.
Same as it is for any other operating system: A primary partition is a "physical" partition that the Legacy BIOS's MBR partition table can recognize. Contrast this with a logical partition, which is a partition stored in an extended partition to work around Legacy BIOS' inability to handle 4 real, physical, primary partitions at a time. Today, on UEFI systems which use GPT, the "primary partition" vs "logical partition" concept is pretty pointless, as you can have as many true-to-life partitions you want on your hard disk due to the face UEFI does things a load better than Legacy BIOS.
On MBR partitioned hard-drives only 4 primary partition can be created. (Use extended and logical partitions to create more partitions).
That depends on what primary partition the fourth extended partition has been placed on. If it was on the first primary partition, it would be /dev/sdb5 (or /dev/hdb5). If it was on the second primary partition, it would be /dev/sdb6 (or /dev/hdb6). If the third, /dev/sdb7, etc... Of course that's assuming you have placed all your logical partitions in a single primary partition. There are several other arrangements you could theoretically have made.
Primary partition is only one
primary
Typically you can only have 4 primary partitions per hard drive if you are using the MBR partition layout scheme. If you need more partitions than the maximum allowed (4), then there is a way to get many more partitions with only one hard drive.By creating an extended partition you can have as many logical partitions as you need within that extended partition, thus you can have more than only four partitions. You can have 3 primary partitions and one extended partition (for a total of 4), and inside the extended partition you can have as many logical partitions as you need.The one thing to keep in mind is that any type of Windows Operating System needs to be installed in a primary partition, otherwise you cannot boot into it. Windows XP in particular, needs to be installed in the first primary partition. For everything else, you can create as many logical partitions as you want inside the extended partition.
A basic disk contains 3 logical partitions, but only one of them can be the primary partition. This is only if the system has enough free space.
4 ----- Dhyan Tripathi You can have 4 primary partitions, or 3 primary partitions and one extended partition containing any number of logical partitions. While you can assign a drive letter to a partition, you can also map it as
