originally the sign is: XOR.
It's the abbreviation of eXcluding OR. (As you may know the connection of two values with OR ( is including)
The XOR-connection is mostly used in computer science to connect 2 bits:
XOR-connection of 2 Bits:
0 XOR 0 = 0
0 XOR 1 = 1
1 XOR 0 = 1
1 XOR 1 = 0
Read 1 = true and 0 = false.
The negated form of the XOR-connection is XNOR.
You'll probably find furthwer and detailed information in wikipedia.
