Every character number or symbol on the keyboard is represented as a in computer memory


What is a character?

Every letter, number, or symbol on the keyboard is represented as a character. Characters are then stored in computer memory. Each character is stored as a character code when you create a document. Character codes can be different depending on the character set that is being used.

In computer memory


All keyboard characters are stored as a number in computer memory. When you press a key on the keyboard, the character code is looked up in computer memory and the corresponding character appears on the screen.

Different character sets use different character codes. For example, the code for the letter A is 01000001 in ASCII, but is 1100001 in EBCDIC.

You can think of a character as a special type of number that is used to represent text.

On the keyboard


A character is any letter, number, space, punctuation mark, or symbol that can be printed. When you type a letter on the keyboard, you are creating a character. Every character number or symbol on the keyboard is represented as a in computer memory. For example, the letter “a” is stored as 01100001. Most characters are represented by a single 8-bit byte. However, some require 2 bytes and a few require 4 bytes.

In order to display characters on the screen, they must be translated into a format that can be understand by the computer. This process is known as encoding. The most common encoding scheme is ASCII (American Standard Code for Information Interchange). However, there are many other schemes in use, such as Unicode and EBCDIC (Extended Binary Coded Decimal Interchange Code).

How many characters are there?

There are 256 characters, including letters, numbers, and symbols. This is because each character is represented by a code that is a number between 0 and 255. When you press a key on the keyboard, the character code is sent to the computer.

In computer memory


ASCII code is the standard code used for information interchange between computers. Each character (number, letter or symbol) is assigned a unique code that a computer can understand. For example, the ASCII code for uppercase M is 77. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another.

In addition to the standard ASCII code, there are variations of ASCII that use different numbers of bits. For example, the Extended ASCII character set uses 8 bits and can represent 256 different characters.

On the keyboard

There are approximately 100 characters on a standard keyboard. This includes the 26 letters of the alphabet, 10 numbers, 32 punctuation/special characters, and various other keys such as the enter key, shift key, and control key.

What is the difference between a character and a symbol?

A character is a letter, number, or other mark that represents an idea, object, or action. A symbol is a character or figure that represents an idea, object, or action.

In computer memory

In computer memory, every character number or symbol on the keyboard is represented as a in binary form. The binary number is then converted into a decimal number which can be displayed as a character on the screen. So, when you hit the “A” key on your keyboard, the computer looks up the binary code for that character and displays the corresponding decimal number on the screen as an “A”.

On the keyboard

On the keyboard, every character number or symbol is represented as a in computer memory. The symbol is then displayed on the screen when the character is typed. When you press a key on the keyboard, you are actually pressing a button that sends a signal to the computer telling it to produce a character.
