<span>A numeric string is created by a cryptographic
algorithm, which is called a hash that is used to validity of a message or authenticity
of a document. The signature is verified by an algorithm that uses the stated
owner of the signature's public key to accept or reject the authenticity of a
signature. A certification authority's digital signature is used to verify the
authenticity of digital certificates and other documents in a PKI.</span>
<h3>Master File :-</h3>
- Master files contain descriptive data, such as name and address, as well as summary information, such as amount due and year-to-date sales.
<h3>Transaction File :-</h3>
- Fast performance with a rapid response is critical. Organisations rely heavily on their TPS with failure possibly stopping business.
<h3>Reference File :-</h3>
- Information in one drawing can be overlaid on a different drawing, eliminating the need to redraw information.
- Proper use of reference files will result in significant time savings and greater coordination of drawings.

Disk defragmentation realigns separated data so that related file pieces are unified. <span> Defragmentation is is the process of consolidating fragmented files on the user's hard drive.</span>This Microsoft Windows utility includes <span>rearranging the fragments and restoring them into fewer fragments or into the whole file.

Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
