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

Assignment –Operating System
Part A - Concepts of OS
Ans 1: there are different types of operating system. The most popular are:
1. Batch Operating System [2]: 
Batch operating system are not suppose to interact with computer in a direct manner. In this operating system an operator who has various responsibilities like taking similar jobs which are having the similar requirement and these requirements are assemble them into batches. The operator is also responsible for sorting the jobs having similar requirements. B
atch system can be shared by multiple users. These operating systems have very less idle time. Batch systems processors have the knowledge about length of the job also. Batch systems are responsible to achieve large work frequently.
Fig 1: Batch Operating System
2. Time-Sharing Operating Systems: 
In time-sharing system, to manage all the tasks work smoothly, for this every task is given some time to execute. Each user use a single system so they gets the time of CPU and these type so systems are also known as Multitasking Systems. The task can be from a single user or different users also. Quantum is the time that every task gets to accomplish and when this time interval is completed then OS switches to the next task. For efficient use of the system, time-sharing operating systems schedule tasks. These systems also consist of accounting software for cost distribution of mass storage, printing, processor time etc. Some important modern operating systems like Android, Linux, BSD, iOS, Microsoft Windows etc.
Fig 2: Time Sharing OS
3. Distributed Operating System – 
These types of the operating system are the most advancement in the field of computers. These are also known as loosely coupled systems. Different types of systems are interconnected computers which are communicated with each other with the help of shared communication network [6]. In distributed OS there are some independent systems also which have their own memory and CPU also. They are different in function and size. In these types of systems one user can access the software or files and these are not really present on his system, but remote access is available in between various devices and all these are connected within that network. 
Distributed OS handles manages a large number of computers and all these assemble together to be worked like a single computer. So we can say that advancement in the networked computers which can communicate with each other helps in advancement of distributed computing. These systems have very less delay in data processing. These all systems work independently like if failure in one but this will not have impact on other network communications. The computation is very fast, as the resources are being shared. As many systems can be added to the network, so these systems are easily scalable.
Fig 3: Distributed Operating System
4. Network Operating System:
These operating system have the ability to manage users, data applications etc. and also these systems run on a server. Sharing of access of files can be allowed by these operating systems and all users have knowledge of underlying configuration, as well as about all the other users within the network, how these are connected etc. so these types of systems are also known as tightly coupled systems [3]. These systems are very much stable and centralized servers. They provide security feature like handled through servers. Remote server access is possible in these os from various locations.
Fig 4: Network Operating System
· Real-Time Operating System:
These systems have time interval required to process the input known as response time. When time requirements that are very strict, so these types of systems are very much required. They can hard real time as well as soft real time systems. When time constraints are very strict, these OS are hard real time systems. Whereas when there is less strict time-constraint, these are soft real time OS. These systms provides more output from all the resources due to maximum utilization of devices. For shifting tasks, time assigned is very less. These systems mainly focuses on running applications. These systems can also be used in embedded systems, as their size of programs are small. These systems are error free and memory allocation easily managed by these systems.

Fig 5: Real time Operating System
Ans 2: There are various parts of Os [7]:
1. Kernel: Kernel is responsible for loading the applications into memory. It have the responsibility to make sure that do not interact with each other. Kernel allows to share use of the CPU and handles file storage also. Kernel is responsible for loading the applications into memory and loading/unloading applications from memory. Kernel is also responsible for file management, data security, for scheduling tasks which is to run on CPU. Unlike the network operating system, single user operating system does not have to deal with networking whereas device such as a mobile phone will have to have particularly efficient memory management kernel, as its memory is a very limited resource. So the Kernel of each type of operating system will have been designed with various...
