請先讀下二頁:
Read the following two pages carefully first :

BINARY Basics

0's & 1's

Summary of
BINARY sites

What is a "digit" ?
Understanding the following :


1. "bit" - 0's & 1's


2. "byte" - 01010101

A "byte" now has 8 bits.
（為求方便計，講述時 "只用" 6 / 4 bits 。 010101 / 0101）

010101

3. "character* "

A B C ... X Y Z

a b c ... x y z

+ - x / =
( [ {
_ \ | # & % $ @ *
> < ^ . , ; : ! ? ~ ` '

0 1 2 3 4 5 6 7 8 9 * Various KEY-top shows a "font".

Actually, each "keying" inputs a "byte series" of the corresponding character,

for example (UNICODE):

0000 0000 0100 0001, the "file name" of font "A"
0000 0000 0100 0010, the "file name" of font "B"
0000 0000 0100 0011, the "file name" of font "C"
..... etc.

0000 0000 0011 0001, the "file name" of font "1"
0000 0000 0011 0010, the "file name" of font "2"
0000 0000 0011 0011, the "file name" of font "3"
..... etc.

Showing an IMAGE of

an "A" font, or
a "B" font, or
.....

a "1" font, or
a "2" font, or
.....

on the "computer screen".

NOTE :

The "bytes" of alphabets or numbers are sequential. （有順序）
These are WHY THEY ARE SEARCHABLE. （可搜索）


4. "Word 英文字" -
一個「儲藏位置 (storage location)」是一串“連續 bytes”的處理單位。
例如：sky，earth，boy，girl，…
One storage location, used as one unit to process a group of consective bytes

(A set of characters, such as "sky", "earth", "boy", "girl", ... ).


5. A "Chinese Word 中文字" is being displyed on a computer screen
through an "Internal Code 內碼* ", a "byte series 處理單位".

For example:（Unicode 中文統一碼）

0101 1001 0010 1001 天 (5929)
0101 0111 0011 0000 地 (5730)
..... etc.

* An "Internal Code (Chinese Unicode)" is a file name （檔案名）of a "Chinese character font".

NOTE :
The "bytes" of INTERNAL CODEs of Chinese characters are NOT sequential.（無順序）
This is WHY THEY ARE NOT SEARCHABLE（無法搜索）.

This is a "fatal drawback 致命傷" of current Chinese computung system!

How can we get out of this hole?
Use "Decimal Numbers 十進位數", not HEXADecimal numbers 十六進位數,
as Chinese INTERNAL CODEs.
WHY ?
See the following page :
