A file whose file descriptor is fd contains the following sequence of bytes: 2, 7, 1, 8, 2, 8, 1, 8, 2, 8, 4. The following system calls
are made:
lseek( fd, 3, SEEK_SET );
fread( fd, &buffer, 4 );
where the lseek call makes a seek to byte 3 of the file. What does buffer contain after the read has completed? What does this sequence represent?
