Data representation of characters
How are the characters represented?
Characters are stored in computer memory using numeric representations.
Each character is assigned a unique numeric value based on the character encoding scheme used, such as ASCII or Unicode.
The numeric value is stored as binary data in memory, typically using a fixed number of bits..
How do you represent a character?

How is text data represented?
In order to represent text, each individual letter or character must be represented by a unique binary pattern.
In order to consistently represent characters from many different languages, these patterns must be agreed throughout the world, through standards such as ASCII and Unicode..
What are the two methods for character representation?
Character data and integer data are two different forms of representation in computer science.
Humans deal with information in the form of symbolic alphabetic and numeric information.
Computers deal with binary-coded decimal (BCD) data, where each wire can conduct an electric or non-electric current..
What is character representation?
A representation of a character as a distinctive bit string that is defined by some character encoding..
What is the character representation?
character representation A representation of a character as a distinctive bit string that is defined by some character encoding..
Character data is commonly referred to as “text.” Digital devices employ several types of codes to represent character data, including ASCII, Unicode, and their variants. ASCII (American Standard Code for Information Interchange, pronounced “ASK ee”) requires seven bits for each character.
How are characters represented in a computer?
Characters must be represented in the computer using the ones and zeros that the hardware can understand and deal with
Although how they are displayed is random, standards have been established to ensure that characters used on one computer are correctly interpreted by another
What is character representation?
character representation A representation of a character as a distinctive bit string that is defined by some character encoding
A character data type allows only a single digit or character. This can include numbers, letters (both upper and lower case) and special symbols (eg £, &, @). String A string can contain one or more characters (eg Hello, ABC123).
Data type
A wide character is a computer character datatype that generally has a size greater than the traditional 8-bit character.
The increased datatype size allows for the use of larger coded character sets.
