black characters: 233
every character consumes 2 bytes. so if your word has 4 characters then it will consume 8 bytes.
10
only uses one byte (8 bits) to encode English characters uses two bytes (16 bits) to encode the most commonly used characters. uses four bytes (32 bits) to encode the characters.
1024 characters is 1,000 bytes, or one kilobyte.
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.
The bytes representing keyboard characters are normally used to index some sort of array (or small database) to decode the information.
512 x 1024 bytes
The word: microprocessors, is 15 characters long, and would need a minimum of 15 bytes to store as ASCII. Some systems may need additional bytes to indicate that text is stored there, or how long the text field is, though.
In the UTF 8 standard of representing text, which is the most commonly used has a varying amount of bytes to represent characters. The Latin alphabet and numbers as well as commonly used characters such as (but not limited to) <, >, -, /, \, $ , !, %, @, &, ^, (, ), and *. Characters after that, however, such as accented characters and different language scripts are usually represented as 2 bytes. The most a character can use is 4, I think (Can someone verify? I can't seem to find the answer).
Field
Bits and Bytes
That depends what encoding is used. One common (fairly old) encoding is ASCII; that one uses one byte for each character (letter, symbol, space, etc.). Some systems use 2 bytes per character. Many modern systems use Unicode; if the Unicode characters are stored as UTF-16 - a fairly common encoding scheme - many common characters will still use a single byte, while many special symbols (for example, accented characters) will take up two bytes. The number of bits is simply the number of bytes multiplied by 8.
