Answer 1

is a short-cut notation for readline( *STDIN );. What readline() does is reads the file handle until it encounters the contents of $/ (aka $INPUT_RECORD_SEPARATOR) and returns everything it has read including the contents of $/. What chomp() does is remove the last occurrence contents of $/, if present.

The contents is often called a newline character but it may be composed of more than one character. On Linux, it contains a LF character but on Windows, it contains CR-LF.

See:

perldoc -f readline
perldoc -f chomp
perldoc perlvar and search for /\$INPUT_RECORD_SEPARATOR/
