How can XOR be used in encryption and what type of encryption is this ?

As we know, XOR is a logical operator which can take 2 inputs and process one output. Given that two parties want to exchange this would be very useful. If A has message 1010 which may stand for "hello" and wants to communicate with party B.we can use an exchange key which is agreed between A and B such as : 0001 and the XOR operator.1010 (message from A)0001 (agreed key between A and B) (XOR)1011 (answer)XOR is symmetric encryption whereby only one key is used to encrypt and decrypt.
