Sure, here's a simple Python program that renames a file:
import os
current_name = 'original.txt'
new_name = 'renamed.txt'
os.rename(current_name, new_name)
print(f'{current_name} has been successfully renamed to {new_name}')
Make sure to replace original.txt
with the actual name of the file you want to rename and renamed.txt
with the desired new name.
Deadlock avoidance involves ensuring that the system never enters a deadlock state by using techniques like resource allocation strategies (e.g., Banker's algorithm) to ensure that resources are allocated in a way that avoids deadlock. Deadlock detection, on the other hand, involves periodically checking the system to see if a deadlock has occurred after it has happened. Deadlock prevention focuses on designing algorithms and protocols in a way that eliminates one of the conditions necessary for deadlock to occur, such as by ensuring that resources are requested in a specific order.
4 by 4 block scheduling refers to a system where students take four classes per day for a semester, typically lasting 90 minutes each. This allows students to focus on fewer subjects at a time and complete a full year's worth of coursework in one semester.
If the master boot record (MBR) becomes corrupted, the computer may not be able to boot properly. This can lead to issues such as a "missing operating system" error or a boot loop. To fix this, you may need to repair the MBR using tools like the Windows Recovery Environment or third-party software.
You can often fix a missing or corrupt boot sector by using the "bootrec" command in the Windows Recovery Environment. You can access this environment by booting from a Windows installation media. In the command prompt, type "bootrec /fixboot" and "bootrec /rebuildbcd" to rebuild the boot sector and repair the boot configuration data.

In a linear system, distances between known points are measured to calculate the position of an unknown point. In an angular system, angles between known points are measured to determine the position of an unknown point. Both methods rely on the principles of trigonometry to accurately locate points in space.

- USER LEVEL THREADS
Aadvantages:
· User-level threads can be implemented on operating system that does not support threads.
· Implementing user-level threads does not require modification of operating system where everything is managed by the thread library
· Simple representation which the thread is represented by a the thread ID, program counter, register, stack , all stored in user process address space
· Simple management where creating new threads, switching threads and synchronization between threads can be done without intervention of the kernel
· Fast and efficient where switching thread is much more inexpensive compared to a system call
- Disadvantages:
· There is a lack of coordination between threads and operating system kernel. A process gets one time slice no matter it has 1 thread or 10000 threads within it. It is up to the thread itself to give up the control to other threads
· If one thread made a blocking system call, the entire process can be blocked in the kernel, even if other threads in the same process are in the ready state
KERNEL LEVEL THREAD:
- Advantages:
· Because kernel has the full knowledge of all the threads, scheduler may decide to allocate more time to a process having large number of threads than process having small number of thread, where the kernel threads come useful for intense application
- Disadvantages:
· Kernel level threads are slow and inefficient, since kernel must manage and schedule all the threads as well as the processes. It requires a full TCB for each thread to maintain information about threads, which results in increasing of overheads and kernel complexity
