Quantum superposition and entanglement are key ideas in quantum mechanics that are causing a revolution in how we encrypt and decrypt data. Quantum superposition lets particles like photons be in more than one state at once. People use this ability in Quantum Key Distribution (QKD) to make and share cryptographic keys. In QKD systems such as BB84, the way photons are polarized helps create encryption keys. Because measuring a quantum system changes it, people can spot attempts to listen in. This ensures keys are shared. As a result, QKD is, in theory, safe from normal ways of intercepting data. It offers a level of security that old-style systems can’t match.
Quantum entanglement links particles making their states affect each other no matter how far apart they are. This boosts encryption methods. People far away can use entangled particles to create shared keys. If someone tries to snoop on their talk, it messes up the entanglement. This warns the real talkers about a possible security risk. We can use this to build super-safe ways to chat. The safety comes from quantum physics laws, not from how hard the math is.

The core functions of an OS include,
Process Management-Keeping track of how and when processes are created, scheduled to run on the processor (CPU), stopped from running, etc. It makes certain that the procedures are performed at a correct rate and it assigns CPU time among all of these processes as well for performing multitasking(tasks).
The OS Manages The Memory Of The Computer (RAM + Cache) In short, it is responsible for managing memory allocation to processes ( mapping ), providing protection between separated regions of the program from accessing not owned data and taking care of swapping pages into disk when RAM run out.
File System Management – OS is responsible for managing files on the computer, such as file types (like image, text), creating new files at particular location in drive or deleting existing ones and granting permissions to add data. It arranges files into directories, and it provides a way by which applications can access and manipulate these files.
