Compare Fields in two Files

Can anyone help me with shell script to this problem.

I have two files as shown below. I want to loop through the two files by comparing column1 in file1 with column1, then column2 and so on till the end in file2 with in file2. If that is found write that individual file to a third file say file3. so at the end the file 3 should contain the difference of both files.

file1

Computers 2.84 49
Printers 1.56 65
Keyboard 1.52 22
Mouse 1.24 35
Webcam 3.99 74

file2

Scanners 5.86 49
