The document discusses memory mapping, memory remapping, and boot blocks. Memory mapping allows portions of files to be accessed as memory addresses. Memory remapping overrides memory region type settings in the memory management unit page tables. The boot block contains the initial program that loads the operating system, allowing it to automatically search storage devices to start up the system.

2. MEMORYMAP
• a mechanism that maps a portion of a file, or
an entire file, on disk to a range of addresses
within an application's address space.

3. APPLICATION
• turns your phone or tablet into an outdoor
GPS and allows you to navigate with 4WD
maps, Topo maps, Street Maps or Marine
charts without the need for maintaining a
phone signal

4. MEMORY REMAP
• The purpose of the memory remap registers
is to remap memory region types.
• The remapping takes place on the outputs of
the MMU, and overrides the settings specified
in the MMU page tables, or the default
behavior when the MMU is disabled.

5. APPLICATION
• the computer's reallocation of usable
memory in the memory map so that the
usable memory contains as much RAM as
possible, at the expense of ROM.

6. BOOT BLOCK
• contains the initial bootstrap program used to
load the operating system.

7. APPLICATION
• To load the operating system.
• automatically search the hard drive and any
USB media sources.
