十進位數 與 二進位數

1 + 1 = 0, 進位 1 (即 1+1=0, 進位 1)
[0001 + 0001 = 0010].

Chinese stopped here some 7,000 years ago!

ASCII & EBCDIC

Note:
(1) IBM computers use EBCDIC.
(2) Mini- & Micro-computers use ASCII.

Internal CODES & LETTERS

JOHN DOE

Letter, Number, or Symbol pattern (dot-matrix) is pre-set in ROM,
internal code(s) actually is(are) Memory ADDRESS(es).
Pattern (Letter, Number, or Symbol) can thus be called out, shown on screen.

"100001" is an executable instruction(addresses), machine language.
"J" is its corresponding "Symbolic Pattern(symbolic addresses)";

"110000" is an executable instruction(addresses), machine language.
"blank" is its corresponding "Symbolic WORD(symbolic addresses)".

THIS IS HOW & WHERE
Computer Language GETS STARTED.

電腦係以 二進位數 運作

How About Chinese?

English Character = 1 ASCII code

Chinese Character = 2 ASCII codes

HexaDecimal System is used
to "represent" BINARY numbers
for simlicity.

為簡潔計, 通常均以 "十六進位數" 表 "二進位數".
例如:
4F = 01001111
B3 = 10110011
....... etc.

INTERNAL CODE 內碼

Chinese characters' INTERNAL CODES are
HexaDECIMAL (ROM addresses),*
0 1 .... 8 9 & A B C D E F,
with character fonts, Chinese thus can be shown on computer screen.

INPUT CODE 輸入碼

ZuYin: Using 26 letters, 10 numbers, & 6 symbols
PinYin: Using 26 letters & 3 numbers
ChongChi: Using 25 letters
TaYi: Using 26 letters, 10 numbers, & 4 symbols
GeoStroke : Using 10 numbers only

Which system has the
shortest character searching time,
least brain effort,
least finger(s) effort?

Chinese KeyBoards

You Know its Input Code
When See a Character.

THE CATCH IS
HOW TO MAKE THE
INPUT METHOD
SIMPLE,
so that an average Chinese can use it EASILY,
and like to use it daily.

要點是:
使漢字數據化, 讓人見字即知輸入碼,
立即可以上機打字.

Digitizing the Chinese characters

You Know its Input Code
When See a Character.
