Multipurpose Internet Mail Extensions (
MIME) is an
Internet standard that extends the format of
email to support:
- character sets other than ASCII
- Non-text attachments
- Message bodies with multiple parts
- Header information in non-ASCII character sets
In computer programming, the term
magic number has multiple meanings. It could refer to one or more of the following:
- A constant numerical or text value used to identify a file format or protocol; for files, see List of file signatures
- Distinctive unique values that are unlikely to be mistaken for other meanings (e.g., Globally Unique Identifiers)
- Unique values with unexplained meaning or multiple occurrences which could (preferably) be replaced with named constants
How could a magic number be bad?
