On Intel x86 PCs, there are two main parts of memory that are further divided into smaller sub-parts:
Low memory (0 to 1MB). This memory is all you can get if you are in real mode (such as when you are running DOS without Extended Memory.). Your modern OS usually will only need this if it really needs to talk directly to the BIOS, such as to set things up and output graphics. Here you have:
- Free memory that the OS can use (to boot up)
- BIOS data
- Video memory
- Memory-mapped BIOS ROM
- The Interrupt Vector Table (used only by DOS and boot programs)
High memory (1MB to whatever you have installed). This part of memory is the most spacious and is what your operating systems and programs normally use.
- LOTS of free memory
- Memory reserved for memory-mapped devices
- Some more BIOS data and code

Difference between primary and extended partitions?
Primary Partitions are logical areas on Coputer storage devices that have direct reference in Master Boot Record. (Due to limitation imposed by MBR only four primary partitions can be created). While Extended partitions refer to logical areas created out of need for more than four Partitions.

A basic disk contains 3 logical partitions how many of these partitions can be primary partitions?
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.
How many primary partitions does MBR support?

Difference between primary and secondary partition?
Primary partitions are the main divisions of a hard drive that can directly contain operating systems, allowing the system to boot from them. A hard drive can have up to four primary partitions. In contrast, secondary partitions (often called logical partitions) are created within an extended partition and are used to organize data without the limitation of the four-partition rule. Secondary partitions cannot be used to boot an operating system directly.
