The answer is natural key. This is considered to be a unique
key in which it is sometimes referred to as the domain key. It is helpful because
when differentiated with the surrogate key, it is existence in the database and
there is no need of having to add a specific column.
True or false: Copyright laws don't apply to works found on the Internet.
Answer is false
Answer:
Caesar cipher
Explanation:
In formation technology, cryptography or cryptology is a process of coding or encrypting information, using algorithms and input values in a network, where there is a present of a third party called adversaries or attackers.
There are different types of cryptography, namely, symmetric, assymmetric and hash cryptography.
Ciphers are algorithms used in cryptography to encode (encrypt) or decode (decrypt) information. An example of cipher is the Ceasar's cipher.
Ceasar cipher is a simple type of substitution cipher that encrpts plain text one character at a time and each coded character depends on the single character and a fixed distance value.
