Cara Membuat Jaringan Komputer LAN Sederhana dan Mudah

Apabila pembaca ingin menghubungkan komputer yang satu dengan yang lainnnya supaya bisa sharing data, printer, sharing koneksi internet dll, kita bisa lakukan dengan membuat jaringan komputer LAN (Local Area Network) sederhana..

Kalau pada postingan yang lalu digunakan koneksi adhoc wireless, pada postingan kali ini kita gunakan koneksi kabel yaitu menggunakan kabel data UTP (Unshielded twisted pair), yaitu standar kabel untuk koneksi jaringan LAN.
Komputer yang dipakai pada saat ini umumnya sudah dilengkapi dengan LAN Card atau disebut juga NIC (Network Interface Controller), atau Ethernet Card.

• Kalau jumlah komputer yang akan dikoneksikan hanya dua buah, kita hanya cukup menyediakan satu buah kabel UTP dengan panjang sesuai jarak antara komputernya yang di kedua ujung kabelnya telah dipasangi konektor RJ-45(standard konektor untuk kabel LAN UTP) dengan konfigurasi Cross/ silang.

• Kalau Jumlah komputer yang akan dikoneksikan lebih dari 2 buah, maka kita harus menambahkan suatu alat yang bernama Switch atau Hub. Pada saat ini harga sebuah switch untuk standard rumahan sudah sangat terjangkau .

Dari masing - masing komputer dihubungkan ke switch menggunakan kabel UTP dengan konektor RJ-45 di kedua ujungnya dengan konfigurasi Straight/lurus.

• Pemasangan konektor pada kabel UTP bisa dibuat sendiri, tetapi untuk mudahnya sobat tinggal pergi saja ke toko komputer yang juga menyediakan peralatan jaringan, dan tinggal bilang untuk membeli kabel UTP sekalian pasangkan konektornya dengan konfigurasi cross/silang untuk koneksi komputer ke komputer(dua buah komputer), ataustraight/lurus untuk koneksi lebih dari 2 komputer / menggunakan switch.

Konfigurasi Alamat IP (Internet Protocol / TCP IP )
Agar dapat saling berkomunikasi , masing – masing komputer harus diberi alamai IP

• Masuk ke Network Connection (Start-->Control Panel -->Network Connection )
• Pilih/dobel klik Local Area Connection
• Dobel klik pada Internet Protocol (TCP / IP)
• Klik Use The following IP address, kemudian isi IP address dan subnet Mask

Misal,

• komputer1 IP Address : 192.168.0.1
• komputer2 IP Address : 192.168.0.2
• komputer3 IP Address : 192.168.0.3
• komputer4 IP Address : 192.168.0.4

dst..
Subnet Mask harus sama : 255.255.255.0



Untuk mengetahui berhasil tidaknya koneksi lakukan perintahping dari komputer satu ke komputer lainnya
Misal dari komputer1 ke komputer2 :

• Di Komputer1 : Klik Start -->Klik Run-->ketik CMD --> klikOK, maka akan tampil Command Prompt
• Ketik ping 192.168.0.2 tekan enter
• harus ada Reply dari komputer2
• akukan perintah yang sama untuk mengetahui koneksi ke komputer yang lainnya.

Semoga Bermanfaat...
