Cara mengira bilangan host dan network

1) 10 . 0 . 0 . 0 / 15
Class A = 255 . 0 . 0 . 0
i) Bilangan Host = 255 . 0 . 0 . 0
1111 1111 . 1111 1110 . 0000 0000 . 0000 0000
= 2^17
= 131072 - 2
= 131070
ii) Bilangan Network = 2^7
= 128

2) 128 . 3 . 0 . 0 / 30
30 = 1111 1100
i) Bilangan Host = 2^2 ii) Bilangan Network = 2^6
= 4 - 2 = 64
= 2

3) 192 . 168 . 1 . 0 / 27 27 = 1110 0000
i) Bilangan Host = 2^5 ii) Bilangan Network = 2^3
= 32 - 2 = 8
= 30

4) 11 . 0 . 0 . 0 / 12
Class A = 255 . 0 . 0 . 0
i) Bilangan Host = 2^20 ii) Bilangan Network = 2^4
= 1048576 - 2 = 16
= 1048574
5) 13 . 0 . 0 . 0 / 30
i) Bilangan Host = 2^2 ii) Bilangan Network = 2^6
= 4 - 2 = 64
= 2

6) 130 . 11 . 0 . 0 / 22 Class B = 255 . 255 . 0 . 0
i) Bilangan Host = 2^10 ii) Bilangan Network = 2^6
= 1024 - 2 = 64
= 1022

7) 132 . 9 . 0 . 0 / 18
Class B = 255 . 255 . 0 . 0
i) Bilangan Host = 2^14 ii) Bilangan Network = 2^2
= 16384 - 2 = 4
= 16382

8) 6 . 0 . 0 . 0 / 9
Class A = 255 . 0 . 0 . 0
i) Bilangan Host = 2^23 ii) Bilangan Network = 2^1
= 8388608 - 2 = 2
= 8388606

  Harini aq belajaq sai TCP/IP...mula2 pening gak kepala dok tgok no...maklum la aq ni elegik ngn no...tp bila en.acap terang punya terang dengan penuh kusyuk serta bersungguh2..teruih faham...hebat toi en.acap ni...terkesima jgak la aq dgaq sai kehebatan dya tentang IT ni kagum2....hehehe..(^___^)



Mula2 aq kompius bab kira binary no 2..tp seb bek en.acap tolong terang bg faham....TQ en.acap..jasamu dikenang...t sya belanja kt pasar malam noh...hehehe....(^___^)

nwtwork...network...network...

mggu depan start belajaq...mai sama2 kita pecah kepala.....heheheh
