What is ASCII code and Hexadecimal code?

ASCII Code and Hexadecimal codes are both used for computers. Computers can only understand binary numbers 0 and 1. For it to understand our input, every letter or symbol has a corresponding code assigned to it. For example, ascii code 1 is read by the computer as 0001, 2 is read by the computer as 0010, and so on.

Decimal	Hexadecimal	Binary
0	0	0000
1	1	0001
2	2	0010
3	3	0011
4	4	0100
5	5	0101
6	6	0110
7	7	0111
8	8	1000
9	9	1001
10	A	1010
11	B	1011
12	C	1100
13	D	1101
14	E	1110
15	F	1111

 table is from http://www.swarthmore.edu/NatSci/echeeve1/Ref/BinaryMath/NumSys.html

Refer to the link for the ascii code and symbols https://www.ascii.cl/ . The first column shows the ascii number, the next column shows the hexadecimal code (these are used to represent large ascii numbers), The last column is the symbol represented by ascii and hexadecimal code.

Hope this helps. Good luck!

What is ASCII code and Hexadecimal code?

ASCII stands for American Standard Code for Information Interchange. It is a character-encoding method that is originally based on the English alphabet that encodes 128 specified characters like the number 0-9, the letters A-Z and a-z, several fundamental punctuation symbols, several control codes that started with teletype machines, and lastly a blank space into the 7-digit binary integers.

ASCII codes correspond to text in communications equipment, computers, and other devices that utilizes text. Almost all modern character-encoding methods are based on ASCII while they support many additional characters. In the computer, a hexadecimal as well as a decimal can be used to produce a character or a symbol. Here are several examples:

• ! – this is an exclamation point. Its decimal value is 33 and the hexadecimal value is 0021.
• “ – this is a quotation mark. Its decimal value is 34 and the hexadecimal value is 0022.
• # – the number sign has a decimal value of 35 and a hexadecimal value of 0023.
• $ – the dollar sign has a decimal value of 36 and a hexadecimal value of 0024.
• % – the percent sign has a decimal value of 37 and a hexadecimal value of 0025.
• & – the ampersand symbol has a decimal value of 38 and a hexadecimal value of 0026.
