128 (0-127), 95 printable, 33 control (for 7 bit ascii that is a through back to teletypes.)
ISO 8859-1 has 256 characters.
From 128 up to 255 we find extra symbols for other languages and regions. Ascci 128 = € for instance and 255 = ÿ.
Of course there are many 8-bit standars, windows-1250, for an example.

How many types of ASCII Code explain it?
There are primarily two types of ASCII code: standard ASCII and extended ASCII. Standard ASCII uses 7 bits to represent 128 characters, including control characters, digits, uppercase and lowercase letters, and some symbols. Extended ASCII expands this to 256 characters by using the 8th bit, allowing for additional characters, symbols, and graphical representations, which vary by encoding system. Common extended ASCII sets include ISO-8859-1 and Windows-1252, which accommodate various languages and special characters.
How many characters can be encoded into ASCII?
ASCII stands for American Standard Code for Information Interchange. It provides a means to facilitate communication on computers. It has 128 characters.
The number of characters ascii standard supports?
ASCII: 128; 95 printable, 33 control iso-8859-1: 256; 191 printable, 65 control unicode: many
Why ASCII has 256 characters?
ASCII, or the American Standard Code for Information Interchange, originally defined 128 characters, using 7 bits for encoding. However, the extended version, known as Extended ASCII, uses 8 bits, allowing for 256 characters (2^8 = 256). This extension includes the original 128 ASCII characters plus an additional set of 128 characters, which include various symbols, letters from different languages, and graphical characters. The use of 8 bits became a standard in many systems, accommodating a broader range of characters for diverse applications.
How many characters are in a kilabyte?
If you're referring to kilobyte, then it contains 1024 bytes and if the characters are the standard ASCII character set where 1 character is 1 byte, then a kilobyte would have 1024 characters.
How many ASCII characters is allowed by SMTP?
SMTP (Simple Mail Transfer Protocol) allows a total of 128 ASCII characters, which includes the standard printable characters (from space to tilde) as well as control characters. However, the actual envelope and header lines are limited to 7-bit ASCII, meaning only the first 128 characters can be used. Each line in an SMTP message is also limited to 78 characters for headers, with a maximum size of 10,000 bytes for the entire message.
How many characters are in the original 7-bit ascii character set?
128
Where can someone go to find a chart of the ASCII characters?
One can go to many places online to find charts of the American Standard Code for Information Interchange. Wikipedia has a very detailed chart of this.
How many bytes are allocated to one ASCII character?
It depends on which of several coding standards you use. ANSI or ASCII uses one byte to define a character, as does BCDIC and EBCDIC. Multi-byte character sets typically have a special character that is used to indicate that the following character is from a different character set than the base one. If the character u-umlaut cannot be represented in the standard set of characters, for instance, you could use two characters, one to say the following character is special, and then the special u0umlaut character. This coding standard requires somewhere between one and two bytes to encode a character. The Unicode system is intended to support all possible characters, including Hebrew, Russian / Cyrillic, Greek, Arabic, and Chinese. As you can imagine, in order to support all these different characters, you need a lot of bits. The initial standard, U16, used two bytes per character; but this proved to be insufficient, so a new standard, U24 which uses three bytes per character, is also now available.
How many special characters are there?
The number of special characters can vary depending on the context or character set being referenced. In standard ASCII, there are 32 control characters and 32 special characters (like punctuation marks). In Unicode, which encompasses a much broader range of characters, there are thousands of special characters across various languages and symbol categories. Therefore, the total count of special characters can differ widely based on the specific system used.
How many characters in 32bits?
If the characters are 8 bits then you have 4 for them in 32 bits. ASCII is an 7 bit character set but in most programming languages a char is 8 bits.
How many ascii code are there?
128 ascii codes.
