Answer:
Hash.
Explanation:
An authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification. Smart cards, digital certificates, picture passwords, and biometrics are generally used to perform an authentication in the field of computer.
Hence, when authenticating a user's password, the password supplied by the user is authenticated by comparing the hash of the password with the one stored on the system.
In Computer science, a hash function can be defined as any function which is used to map data by accepting a block of data with variable length size or arbitrary size as input to produce a fixed size hash values or codes.
Generally, when a block of data (input) of arbitrary size is hashed, the resulting hash values or codes is usually smaller than the input data. Thus, hash functions are considered to be a compression of data and as a result, sometimes called compression functions. Basically, the block size of a hash function typically ranges from 128 bits to 512 bits.
Answer:
1.) Relative cell reference - A1
2.) Absolute cell reference - $D$2
3.) Mixed cel reference - $D2
Explanation:
In Microsoft Excel, cell references are very important and critical when dealing with formula. They can give you what you’re looking for or make your entire worksheet incorrect.
A cell reference is a cell address or a range of cell addresses that can be used in a formula.
There are three types of cell references and they are;
a) Relative reference
b) Absolute reference
c) Mixed reference
A relative cell reference is a cell reference that changes when you copy the formula to other cells. It s usually just a normal cell reference like A1, B2, C3. If a formula with a relative cell reference is copied down to other cells, the formula will change. That is a formula with a relative cell reference changes with respect to the cell which it is copied to.
An absolute reference does not change when you copy the formula to other cells. In absolute references, the dollar sign $ is used to “lock” both the row and column so that it does not change when it is copied to other cells. An example is $D$2.
Using a mixed cell reference, one is trying to see that only either the row or column changes with respect to other cells when they are copied. It is like “locking” either the column or the row while changing the other. Just like from the example, $D2 is a mixed cell reference where only the column is locked such that only the row changes when the formula is copied to other cells.

Answer:
List items are usually accessed using the indexing operator.
Explanation:
Depends on the language, and what you mean with extracting? Do you mean accessing or removing?
