Installasi Java Card Kit 2.2.2
Instalasi java card kit 2.2.2 yang dijelaskan berikut dijalankan di OS windows XP service pack 2.
Pertama, sebelum kita instalasi java card kit 2.2.2, anda perlu mengunduh (download) terlebih dahulu installernya di sourceforge atau anda dapat mengakses alamat http://java.sun.com/javacard/ untuk informasi lebih lengkapnya.
Setelah anda mendapatkan file java_card_kit-2_2_2-windows.zip, ekstrak pada drive c:\. Didalam folder ekstraksi anda akan menemui beberapa file berekstensi zip. Diantaranya adalah :
-
java_card_kit-2_2_2-rr-bin-docs-do.zip;
-
java_card_kit-2_2_2-rr-ant-tasks.zip;
-
java_card_kit-2_2_2-rr-bin-windows-do.zip; dan
-
java_card_kit-2_2_2-rr-specs.zip.
Ekstrak semuanya pada folder yang sama. Kemudian untuk mempermudah akses perintah-perintah java card kit, anda perlu menambahkan beberapa parameter pada environtment anda. Cara yang paling mudah adalah dengan memilih properties dari my computer (start>My computer>properties) dan pilih environtment pada tab advaced.
IP Addressing Work book
IP Address Classes
Class A 1 – 127(Network 127 is reserved for loopback and internal testing) Leading bit pattern 0 00000000.00000000.00000000.00000000
Class B 128 – 191 Leading bit pattern 10 10000000.00000000.00000000.00000000
Class C 192 – 223 Leading bit pattern 110 11000000.00000000.00000000.00000000
Class D 224 – 239 (Reserved for multicast)
Class E 240 – 255 (Reserved for experimental, used for research)
Private Address Space
Class A 10.0.0.0 to 10.255.255.255
Class B 172.16.0.0 to 172.31.255.255
Class C 192.168.0.0 to 192.168.255.255
Default Subnet Masks
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0

ANDING With Default subnet masks
Every IP address must be accompanied by a subnet mask. By now you should be able to look at an IP address and tell what class it is. Unfortunately your computer doesn’t think that way. For your computer to determine the network and subnet portion of an IP address it must
“AND” the IP address with the subnet mask.
Default Subnet Masks:
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0
ANDING Equations:
1 AND 1 = 1
1 AND 0 = 0
0 AND 1 = 0
0 AND 0 = 0
Sample:
What you see…
IP Address: 192 . 100 . 10 . 33
What you can figure out in your head…
Address Class: C
Network Portion: 192 . 100 . 10 . 33
Host Portion: 192 . 100 . 10 . 33
In order for you computer to get the same information it must AND the IP address with the subnet mask in binary.
IP Address :11000000 . 1100100 . 00001010 . 00100001 : (192 . 100 . 10 . 33)
Default Subnet Mask: 11111111 . 1111111 . 11111111 . 00000000 : (255 . 255 . 255 . 0)
AND : 11000000 . 1100100 . 00001010 . 00000000 : (192 . 100 . 10 . 0)
ANDING with the default subnet mask allows your computer to figure out the network portion of the address.
