Answer / Ritu Brijpal Saini
"The core concepts of Unix include:
1. Processes: A program in execution is known as a process. Unix supports multiple processes that can run concurrently.
2. File System: Unix uses a hierarchical file system, which organizes files and directories in a tree-like structure.
3. Users and Groups: Unix supports multiple users and allows controlling access to the system through user accounts and groups.
4. Shell: A command-line interface that allows users to interact with the operating system and execute commands.
5. I/O Redirection: Allows manipulating input and output streams to and from files, pipes, and other programs.
6. Pipes (|): Allows chaining commands together to process data streams in a pipeline.
7. Signals: A method for sending messages or signals between processes and the kernel."n
