名詞翻譯

Transistor 電晶體

Semiconductor 半導體

Integrated Circuits(IC)

Digital Circuits 數位電路

Combinational Circuits 組合電路

*Sequential Circuits 序位(順序)電路=>受到output影響也受input前數值影響



commutative 交換

associative 結合

distributive 分配

identity 一致

complement 搭配

--------------------------

1 bit 0 → 1

2 bit 0 0 → 1 1 (0 -> 3)

3 bit 0 0 0 → 1 1 1 (0 -> 7)

4 bit 0 0 0 0 → 1 1 1 1 (0 -> 15)

10 bit (0 -> 1023) >> 1024 <= k = 10^3 ≒ 2^10

20 bit (10^6)

-----------------------------------------------------

KB : 2^10

MB : 2^20

GB : 2^30

------------------

XOR sum = A ⊕ B

AND carry = A．B

NAND X = (A．B)'

OR X = A + B

NOR X = (A + B)'

_

A , A' => NOT A

電腦用byte

網路用bit
