A file system is a collection of files and folders that are stored on a computer's hard drive. These files can be anything from documents and pictures to music and software.
The file system is divided into two main parts:
The file system table (FAT): This table stores metadata about each file, such as its name, size, and location on the hard drive.
The data block manager (DBM): This manager reads and writes data from the hard drive to the files on the system.
Extensions are a set of characters that are added to the end of a file to indicate its type. For example, the extension for a document file is ".doc", while the extension for a PDF file is ".pdf".
There are many different file systems available on computers, each with its own strengths and weaknesses. Some of the most common file systems include:
FAT: This is the most common file system on personal computers. It is a simple and efficient file system that is used on most computers.
NTFS: This is a more advanced file system that is used on Windows computers. It is more efficient than FAT and supports a wider range of file types.
EXT4: This is a very fast and efficient file system that is used on many servers.
APFS: This is a new file system that is used on Apple computers. It is faster and more secure than FAT and NTFS.
File extensions are used to help computers identify and open files. When you double-click on a file, the operating system looks up the extension and uses the corresponding software to open the file.
