Explain what are the unix system calls for i/o?
Answer / Sandip Kumar
In Unix, system calls are used to access the operating system services. For Input/Output operations, some common system calls include: read() - reads data from a file into a buffer, write() - writes data from a buffer to a file, open() - opens an existing file or creates a new one, close() - closes an open file, lseek() - changes the position of the file pointer for I/O operations.
