Noob question about fdisk -l output

[derekpittx]

I'm taking an intro to Linux online course and this week's video lectures are discussing storage drives/partitions/etc. One question on my assignment asks us to run the fdisk -l command and then screenshot the output, which I did. It then asks what each column of the output for our /dev/sda device means. From my following output, I'm assuming my professor is referring to device, boot, start, end, and so on.



Device Boot Start End Sectors Size Id Type

/dev/sda1 * 2048 20969471 20967424 10G 83 Linux



I've gathered the meaning of the device , size, and type columns, but can't find an explanation of the others anywhere in my course materials or online. Just wondering what the numbers under start, end, sectors, and Id represent. Thanks.

Partition type Id which is described in the next column.
