Special Character A

Some editors despise the use of often-used special characters, such asA special character is one that is not considered a number or letter. Symbols, accent marks, and punctuation marks are considered special characters. Similarly, ASCII control characters and formatting characters like paragraph marks are also special characters. Unlike alphanumeric characters, special characters are extremely versatile and can be used for a number of different purposes in writing, coding, and mathematical operations.

Use

Special characters are often required when creating a strong password. This is because they add complexity to the password and reduce the chances that the user’s account will be hacked. Many hackers use lists of common or easily guessed phrases and combinations of characters (such as “password” and “1234”) to gain access to a user’s account, so special characters make the password less predictable. However, special characters that are used in predictable ways (like replacing “a” with “@” or “s” with “$”) have lost their effectiveness when it comes to password strength.

A special character is a character that is not an alphabetic or numeric character. Punctuation marks and other symbols are examples of special characters. Unlike alphanumeric characters, special characters may have multiple uses. To prevent problems, some special characters may also need to be escaped or encoded when used in the command line and programming languages. (Source: www.computerhope.com)

Character

Historically, the term character was also used to just denote a specific number of contiguous bits. While a character is most commonly assumed to refer to 8 bits (one byte) today, other definitions, like 6-bit character code was once popular (using only upper case, while enough bits to also represent lower case, not with numbers and punctuation allowed for), (Source:

Computers and communication equipment represent characters using a character encoding that assigns each character to something – an integer quantity represented by a sequence of digits, typically – that can be stored or transmitted through a network. Two examples of usual encodings are ASCII and the UTF-8 encoding for Unicode. While most character encodings map characters to numbers and/or bit sequences, Morse code instead represents characters using a series of electrical impulses of varying length.
