Hi mate, well this is a very crucial question for me as well so please if you figure out the answer send it to me as soon as possible to my email address below. But please make sure to change some of the contents in the answer so that my lecturer Wan Li doesnt figure out that we submiting the same answer. Cheers. david.clark@canberra.edu.au

Does a paged memory management system have the fragmentation problem at process image level?
No, not at all
Compare Contiguous memory allocation with internal fragmentation?
in early, computer system has contiguous memory allocation,each process is allocated in a single contiguous(together) memory!!(allocating into memory addresses one by one,)it has tackled memory fragmentation(both internal and external). not allocating for a fixed size memory block.so no internal fragmentation, allocating contiguously ,so no external fragmentation!!!
Difference between internal fragmentation and external fragmentation in operating system?
Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request. External Fragmentation: External Fragmentation happens when a dynamic memory allocation algorithm allocates some memory and a small piece is left over that cannot be effectively used. If too much external fragmentation occurs, the amount of usable memory is drastically reduced. Total memory space exists to satisfy a request, but it is not contiguous. Internal Fragmentation: Internal fragmentation is the space wasted inside of allocated memory blocks because of restriction on the allowed sizes of allocated blocks. Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used
Operating system manges memory?
An Operating System manages resources. Memory is one example of resource management.
When you perform compaction in memory management system?
When the memory resources are scarce. We use compaction.
List three functions of an operating system?
The three main functions of an Operating System are process management, memory management and file management.
What is the role of operating system in memory management?
Role of the Memory management unit in Operating system Every program for its execution requires some space in computer memory which is provided by memory management unit using virtual memory that provides the external storage addressing location for the programs that does not have too much space in main memory for their execution and saved them in secondary memory but when required loaded them again in main memory. This deallocation and reallocation of programs in main memory deals with concurrency. At last, we say that loading capabilities of programs with the memory addressing is there in it.
Components of an operating system include process memory and file management. What is another component of an operating system?
input/output (I/O) system management

Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being usedAnother Definition:Internal Fragmentation is the area in a region or a page that is not used by the job occupying that region or page. This space is unavailable for use by the system until that job is finished and the page or region is released.
What is a task performed by an operating system?
-Memory Management -Process Management -Disk and File System Management -Networking -Security -Graphical User Interface (GUI) -Device Driver Management
Explain terminoligy used in computer defragmenter?
The more you change things on your computer the more fragmentation of your computer memory you are making. here are some computer operating systems that will automatically reduce the amount of fragmentation you will have. Most computers will still have some fragmentation of files on the hard disk. You have, as part of the operating system of your computer the ability to 'tidy up', or remove fragmentation mostly running the operating system defrag program. This will mean your computer will put everything you use most at the easiest to access end of your memory, this means that the computer works as fast as it can
