A re-entrant program (or a thread-safe program, if you're more familiar with UNIX) is a program that doesn't change itself. I know what you're thinking: "how can a program change itself?" Well there are actually three parts to a computer program:

  • Program code - the instructions that are executed when a program runs.
  • Constants - constants used in a program. These are set when the program is written, and never change.
  • Storage area - or variables. This area changes as the program runs.

Advantages of paging together with segmentation?

Paging together with segmentation offers the advantages of both memory management techniques, enhancing efficiency and flexibility. Paging allows for non-contiguous memory allocation, which reduces fragmentation and optimizes memory usage. Meanwhile, segmentation provides a logical division of memory, enabling programs to be organized into meaningful units, such as functions or data structures. This combination allows for better access control, easier sharing of code, and improved overall system performance.
