ASCII is 7 digits, isn't it?

1 byte. 8 digits as binary, 2 digits as hexa.
(2 bytes for extended chars)

01001000 01101001 = 48 69 as hexa

48="H" (capital)
69="i" (small)

so 01001000 01101001 = "Hi"

got it?

you must be right but when we did it at school im sure i rember the conversion chart having 3 numbers for the collem and 4 for the row

That's coz the letters all have a zero at the start, which you might as well not print coz it's only a zero.

conversion chart? :bugeye:
I never use it for calculate base X numbers. I use pure math. binary number is base 2. it means binary has 2 symbols (0 & 1) in numbers.
hexadecimal is base 16. it have 16 symbols (0..F) in hexa numbers.

We can make any X-base numbers, but computers using binary numbers and boolean calculation in it's proccess. 0 as OFF, 1 as on.

If you can make computer using -1 (negative voltage), 0 (off), and 1 (positive voltage) in it's computing proccess, you should use base 3 numbers on your logic calculation.

No i could do the conversions to ANY base in my head or on paper the chart was for coverting ascii to the alphabet and the other caricters like !@#$%^&*() 13. ### sjmarshaRegistered Senior Member Messages: 363 hmm well done... Perhaps that was a little to easy... A little dissapointing really, well theres no prize Please Register or Log in to view the hidden image! I will think of a harder one... 14. ### sjmarshaRegistered Senior Member Messages: 363 <------------------ Ok I did another one. This should take a little longer to find out....I hope.... 15. ### XevRegistered Senior Member Messages: 10,943 Pardon, stupid question: What is ASCII? 16. ### Adam§Þ@ç€ MØnk€¥Registered Senior Member Messages: 7,415 ASCII = American Standard Code for Information Interchange. Just an encoding type that was adopted around the world for characters. 17. ### CrisIn search of ImmortalityValued Senior Member Messages: 9,199 ASCII = American Standard Code for Information Interchange. Another common code is = EBCDIC = Extended Binary Coded Decimal Interchange Code. Both systems define an 8 bit pattern that can be used in a single byte to represent a character. With 8 bits there can be 256 combinations. Probably most of the characters being displayed on your computer screen asre being held in memory as ASCII characters. Hope that helps.

I thought that using low hexadecimal numbers might have thrown you off the trail. Moving away from ASCII i will do something different later. Not enough time now... 21. ### WildCardRegistered Member Messages: 20 ASCII stupid question, get a stupid ANSII.

Look in the table below for the 2 hex digits and the corresponding character next to them. Remember that not all characters can be displayed as some represent control functions. Hexadecimal ASCII CODE 00 NUL| 10 DLE| 20 SP| 30 0 | 40 @ | 50 P | 60 ` | 70 p 01 SOH| 11 DC1| 21 ! | 31 1 | 41 A | 51 Q | 61 a | 71 q 02 STX| 12 DC2| 22 " | 32 2 | 42 B | 52 R | 62 b | 72 r 03 ETX| 13 DC3| 23 # | 33 3 | 43 C | 53 S | 63 c | 73 s 04 EOT| 14 DC4| 24$ | 34 4 | 44 D | 54 T | 64 d | 74 t

0C NP | 1C FS | 2C , | 3C < | 4C L | 5C \ | 6C l | 7C |
0D CR | 1D GS | 2D - | 3D = | 4D M | 5D ] | 6D m | 7D }
0E SO | 1E RS | 2E . | 3E > | 4E N | 5E ^ | 6E n | 7E ~
0F SI | 1F US | 2F / | 3F ? | 4F O | 5F _ | 6F o | 7F DEL

Please note: There are synonyms for some of the symbols. For example,

0A = NL (new line) is also called LF (line feed)
0C = NP (new page) is also called FF (form feed)

Have fun
Cris
