Question

How many codes do ASCII computers have? * ONE EXAM

Answer 1

ASCII computers have a total of 128 codes.

Step-by-step explanation:

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers. It uses a set of 128 codes to represent characters, including letters, numbers, symbols, and control characters. These codes allow computers to understand and display text in a consistent manner.

Each code in ASCII is represented by a 7-bit binary number, which means there are 2^7 or 128 possible codes. For example, the code for the letter 'A' is 65, the code for the number '5' is 53, and the code for the symbol '#' is 35.

So, ASCII computers have a total of 128 codes.

Answer 2

ASCII originally consists of 128 characters, but the Extended ASCII version has a total of 256 characters to include additional symbols and language-specific characters.

Step-by-step explanation:

The American Standard Code for Information Interchange (ASCII) is a character encoding standard used in computers and other devices. ASCII was originally based on a set of 128 characters, which include 95 printable characters and 33 control characters. These characters are represented by 7-bit binary codes, ranging from 0000000 to 1111111.

However, to accommodate more symbols and characters from different languages, an extended version of ASCII, often referred to as Extended ASCII, uses an 8-bit binary code, allowing for an additional 128 characters, bringing the total to 256 unique symbols or characters.
