while studying for my MCDST cert I learned about Primary partions and extended partitions. From the textbook:
****Primary A primary partition can be set as the bootable partition. A computer running a Windows operating system can have up to four primary drives (three if you also have an extended partition on the disk). Any primary partition may be configured as the active, or bootable, drive, but only one primary partition can be active at any time. When you are configuring a multiple boot computer, you will create a primary partition for each operating system and then install each operat ing system onto a different primary partition.
****Extended An extended partition provides a way to get around the four primary partition limits. You cannot format an extended partition with any file system. Rather, extended partitions serve as a shell in which you can create any number of logical partitions.
My question is: What are the differences? If an extended partition allows you to bypass the 4 primary partition limit, why have primary partitions at all?
