What is a page table base register?
Each process running on a processor needs its own logical address space. This can only be realized if each process has its own page table. To support this, a processor that supports virtual memory must have a page table base register that is accessible by the operating system. For operating system security, this register is only accessible when the processor is in system mode. The operating system maintains information about each process in a process control block. The page table base address for the process is stored there. The operating system loads this address into the PTBR whenever a process is dispatched.
Explain all types of operating system with diagram?
There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
Describe three general methods for passing parameters to the operating system?
1) Pass parameters using registers(directly). 2) Store the parameters in a table in memory and the table address is passed in a register to the OS. 3) Push(store) the parameters onto a stack(by the program) and "pop" off by the Operating System.

What is device status table in operating system?
The device status table in an operating system is a data structure that maintains information about the various I/O devices connected to the system. It typically includes details such as the device's state (e.g., idle, busy, or error), its type, and any specific attributes or configurations. This table helps the OS manage device operations efficiently by tracking which devices are available for use and coordinating access to prevent conflicts between processes. Ultimately, it plays a crucial role in the overall device management and resource allocation within the operating system.
What is the significance of a valid bit in a page table and how does it impact the overall functionality of the page table system?
The valid bit in a page table indicates whether a page is currently in use or not. It impacts the functionality of the page table system by helping the operating system efficiently manage memory. When a valid bit is set, it means the page is in use and can be accessed by the CPU. If the valid bit is not set, it indicates that the page is not currently in memory and the operating system needs to retrieve it from secondary storage. This helps prevent unnecessary memory accesses and improves system performance.
