Section 1: How does an operating system manage memory?
A computer’s memory must accommodate both the Operating System’s
processes and user processes. The following outline describes what happens
when a user starts a program such as MATLAB.

2. The operating system creates an address space for the program to run in,
which involves setting up approprate page tables.
3. The program's text and data segments are mapped from the executable file
on disk to the virtual address space, the former being mapped as read-only,
