With reference to process management, explain the terms a) External Priority b) Purchase Priority c) Internal Priority d) Slice Priority
1) External Priority: - The user specifies the priority externally at the time of initiating the process. If the user does not specify any priority, operating system assumes a default priority for that. If the job is too urgent, system manager permits the process at a higher priority.
2) Purchased Priority: In this priority higher priority processes are charged at a higher rate. The operating system keeps the track of the time used by each process and charges it accordingly.
3) Internal priority: It is decided by scheduling algorithms. Their calculations are based on the current state of the process. The following scheduling algorithms are used for that.
(i) Shortest Job First Algorithm: The job whose expected time for completion is less is executed first.
(ii) Expected remaining time to complete: It is same as SJF at the beginning but as the process progresses the time will change. At regular intervals operating system calculates the expected remaining time for completion and accordingly priority is determined.
4) Time Slice: A short interval of time allotted to each user or program in a multitasking or timesharing system. Time slices are typically in milliseconds.

What is a file system? Explain tape based and disk based file system
A filesystem is the methods and data structures that an operating system uses to keep track of files on a disk or partition; that is, the way the files are organized on the disk. The word is also used to refer to a partition or disk that is used to store the files or the type of the filesystem.
There are two types of file systems:
Tape-based systems: -It is of sequential type.
Tape-based systems are simple but inefficient
In these systems, files are stored on to reels of physical tapes. Generally, one or more files are stored on to one tape
Tapes are used for transport of data from one computer to another.
Disk-based systems:- It is direct access through physical address
Each disk is divided into tracks and each track is further divided into the number of sectors
A number of tracks and size of sectors is variable. It varies from one drive to another.
A disk has a device directory, indicating, which files are on the disk. The directory lists the
file name, starting address, file length, type of file, time of creation, and time of the last update etc

What is Graphical User Interface?
GUI stands for graphical user interface. A GUI, which some folks pronounce as 'gooey', is exactly what it sounds like... a graphical way to do stuff. Simply put, a graphical user interface is a way to communicate what you want to a computer application (or computer operating system) using graphical symbols rather than typing the instructions in. GUIs let you work with picture-like items (icons and arrows for example) to tell the computer what you want from it. And, rather than a keyboard (which can leave you guessing what to type next), you get to scoot around a blocky thing on your desk called a mouse, which makes the arrows and icons scoot around on the screen

Explain the following process states a) Running state b) Ready state c) Blocked state
a) Running State: When a process is in the running state, it means that the CPU (Central Processing Unit) is actively executing the instructions of that process. In this state, the process is utilizing the CPU resources and executing its designated tasks
b) Ready State: When a process is in the ready state, it is prepared to run and is waiting for the CPU to be allocated to it. Processes in the ready state are loaded into the main memory and are awaiting their turn to execute.
c) Blocked State: When a process is in the blocked state (also known as the waiting or blocked/sleeping state), it is temporarily unable to proceed with its execution. The process enters this state when it encounters an event that causes it to halt, such as waiting for user input, waiting for I/O operations to complete, or waiting for a certain condition to be satisfied

What is Virtual memory? Explain any two elements of Virtual memory
Virtual memory:
1. Virtual memory is an attempt, which makes the execution of the processes possible, which may completely not in the main memory. Some part of the process may be on disk.
2. The MM techniques are simple to implement but the major drawback is that if the physical memory is limited then number of processes it can hold at any time i.e. degree of multiprogramming reduces. For this concept of virtual memory is introduced.
Elements of virtual memory
1. Locality of reference
2. Page fault
3. Working set
4. Page replacement policy
5. Dirty page
6. Demand paging
Page fault : When a page, which is not in main memory is referenced, then a page fault arises. At this time
the O.S loads that page in main memory.
Working set : The set of pages in physical memory which are actively referred to any moment is called as working set. Working set helps to decide page replacement policy.

State the various steps involved in the allocation of partition in case of fixed partition memory
(1) It is the simplest method for memory allocation. It divides the memory into fixed size sections. These sections are called as partitions. Each partition may contain exactly one process. When the partition is free, a process is selected from the input queue and loaded into free partitions. When the process terminates, the partition becomes available for another process.
(2) The partitions are fixed at the time of system generation. It is the process of tailoring the operating system to specific requirements. After declaring partitions the operating system creates a partition description table.
(3) The Memory Map for processes is as follows:
Process: P0-(0-200K)
Process: P1-(200-700K)
Process: P2-(700-800K)
Process: P3-(800-1100K)
