Depending on the seriousness of the case, penalties can vary from a written warning or zero marks to exclusion from the course or rescinding the degree. Students should make themselves familiar with the full policy and procedure available at: http://www.mit.edu.au/about- mit/institute-publications/policies-procedures-and-guidelines/Plagiarism- Academic-Misconduct-Policy-Procedure.

Today’s world there are different types of operating system exist in everyday applications. Research the Internet or current literature to find at least five types of operating systems depending on the application. (10 marks) Please note: Whenever you research computer technology, make sure your resources are timely. Notice the date when the research was published. Also be sure to validate the authenticity of your sources. Avoid any that might be questionable, such as blogs and publicly edited online (wiki) sources. 2. List different parts of operating system. Describe how those parts are collaborate to perform the task of operating system. (5 marks) Part B Memory Management (5 Marks) ----------------------------------------------------------------------------------------------------------------------------------- 3. Explain in your own words why operating system needs address translation i.e., logical address to physical address conversion? Also provide an example of address translation. Memory Fragmentation and Compaction (6+6=12 Marks) ----------------------------------------------------------------------------------------------------------------------------------- 4. The sizes of pages and page frames are often identical. Search academic sources to discover typical page sizes, what factors are considered by operating system developers when establishing these sizes, and whether hardware considerations are important. Cite your sources. (3 +3 = 6 Marks) 5. Given three subroutines of 700, 200, and 500 words each, if segmentation is used then the total memory needed is the sum of the three sizes (if all three routines are loaded). However, if paging is used then some storage space is lost because subroutines rarely fill the last page completely, and that results in internal fragmentation. Determine the total amount of wasted memory due to internal fragmentation when the three subroutines are loaded into memory using each of the following page sizes: a. 100 words b. 600 words c. 700 words d. 900 words

Part B
Answer 3 : The main memory provides faster accessing speed than secondary memory because it is smaller in size. By loading the required files or process into the main memory, computer can process data much more quic
kly. Due to the larger size of secondary memory, it is slower in data accessing. Therefore, to access data from the main memory, operating system needs address translation from logical address to physical address.
The logical address is generated by CPU while a program is running whereas the physical address is used to identify a physical location of required data in a memory. 
The mapping of logical address to physical address is done by the memory management unit (MMU), a hardware device. The working of the mechanism to convert logical address to physical address is as follows:
The CPU generates the logical address which is the offset for the address in relocation register. The limit register specifies the limit (relative to the base address) of the process The base address of the process in the main memory is stored in the relocation register. The logical address value (if lies inside the limit of the process) is added to the base address in relocation register and the resulting address is the address of the memory to be referenced .If the value is more than the limit given, it is an invalid memory access. In this case, CPU traps to the operating system, and the OS terminates the program.
Formula : Base address + offset
For example :
The base address for the process inside the memory is 2254 and the CPU generated a logical address of 300. The range of this process is 500. Then,
Physical Address = Base Address + offset
= 2254 + 300
= 2554
Keeping the limit same, if the logical address generated is 800, since 800>500, it is an invalid memory access. The Operating System will terminate the program.

Answer 4:
A page in the secondary memory has the same size as a frame in the main memory.
Usually, processor architecture is used to determine the page size. The pages in a system traditionally had a uniform size of 4,096 bytes. Now, due to the benefits, the processor designs allows two or more page sizes.. Several points factor into choosing the best page size.
1. Page Table Size : The system having smaller page sizes will require more pages, making the page table occupy more space. Example...
