File system is the method by which an OS stores, organizes, and manages access to files on a storage device.

A file system in a computer is the method by which files are named and organised logically for storage and retrieval. Without a file system, data would not be isolated into distinct files and be challenging to locate and retrieve. The organisation and accessibility of individual files are becoming even more crucial for data storage as data capacities rise.

Using the same logic-based method of document storage and retrieval, digital file systems and files are named after and modelled after paper-based filing systems.

Operating systems (OS) like Microsoft Windows, macOS, and Linux-based systems can have different file systems. Some file systems are created for particular uses.

An index of all the data on a storage device can be thought of as a file system, which stores and organises data. Hard drives, optical drives, and flash drives are some examples of these gadgets.

The maximum number of characters that can be used in a name, the permitted characters, and, in some systems, the length of the file name suffix are all specified by file system conventions. File names are frequently not case sensitive in file systems.

What is driver?
A device driver in computing is a computer software that manages or regulates a specific kind of device that is connected to a computer other automaton. A driver offers a software interface to hardware devices so that operating systems and other computer programmes can access hardware operations without having to be aware of the exact specifications of the hardware being utilised.

Through the computer bus and communications subsystem that the hardware links to, a driver communicates with the device. When a calling software calls a driver routine, the driver sends instructions to the device (drives it). The driver may call functions in the original calling application once the device transmits data back to it.

Anycast is a technique is used to balance traffic by iterating a list of items such as location, congestion, or link health, This helps cut down on latency and bandwidth costs, improves load time for users, and improves availability.

What is Anycast?

Incoming requests can be routed to a variety of different locations, or "nodes," using the network addressing and routing technique known as "anycast."

Anycast typically directs incoming traffic to the closest data center with the ability to process the request quickly in the context of a CDN. Anycast networks can withstand high traffic volumes, network congestion, and DDoS attacks thanks to selective routing.

How does Anycast Work?

It is possible to distribute incoming connection requests among various data centers using anycast network routing. The Anycast network distributes data based on some prioritization methodology when requests arrive at a single IP address connected to the network.

The decision-making process for selecting a specific data center is typically optimized to reduce latency by choosing the data center that is closest to the requester. Anycast, one of the five main network protocol techniques used in the Internet protocol, is characterized by a 1-to-1 of many association.

A subnet mask is a 32-bit integer that is produced by setting all host bits to 0 and all network bits to 1. The subnet mask does this by dividing the IP address into network and host addresses. The "0" address is always a network address, but the "255" address is always allocated to a broadcast address.

Hence, The subnet mask for a class C network would be 255.255.255.0, which indicates that 24 bits are being used for the network. This is shown in CIDR notation by adding a /24 after the IP address.
