Do repair and setting to repeat network connection

1) connection repair preparation in network with bus topology

Be physical topology that uses cable coaxial with

use t-connector with minator 50 ohm at the end of

network. bus topology uses one the end second cable

closed with along cable found node.

bus topology characteristics:

- be one the end second cable is closed where

  along cable found node.

- most prevevalent because simple in installation

- signal merewati 2 directions with one possibility cables happens

  collision (data collision or campurnya data).

- biggest troubleshoot if happens to broken off or spacious in wrong

  one konektor so entire networks will stop

- bus topology where signal accepted and transmission line

sent in every tool/device that continued in one line

straight (cable), signal only be caught by tool that aimed,

while another tool not aim ignore signal

/only be passed by signal

 

picture 1 network with bus topology

preparation that with prepare the device. device or ingredient that wanted for network

with bus topology :

a) network card (network interfaces card/ lan card)

a network card (lan card) pair in slot

expansion in a motherboard also server computer

workstation (client) so that computer can related to into

network system. seen from kind interface- in pc found

          two kinds that is pci and isa

                                     

a)                                                                     b)

a)    network card (lan card) ISA with konektor BNC and RJ45

b)   network card (lan card) ISA with konektor BNC

b) cable and connector

cable that used for network with bus topology use cable coaxial. cable coaxial prepare

good enough protection from cross talcum powder (caused electricity field and phase signal) and electical inteference (come from thunder, motor

and radio system) because found a kind of patron metal/metal in cable.

cable kind coaxial mengantaranya television cable (antenna cable), thick

coaxial and thin coaxial transfer speed rate data maximum 10

mbps.

cable coaxial or cable rg-58 or cable 10base2 (ten base two)

has reach between 300 m and can achieve on 300m

by using repeater. to serve the purpose of

network cable must fulfil standard ieee 802.3 10base2,

with average diameter revolves 5 mm and usually coloured dark.

 

                                                                                       

picture 3. kind cable coaxial or rg-58/bnc

Connector that used in bus topology network by using konektor bnc. konektor bnc there 3 kinds that is:

a) CONNECTOR BNC

konektor bnc that installed in cable ends coaxial.

b) MINATOR BNC

konektor bnc installed in network ends with bus topology that has obstacle value 50 ohm.

c) TBNC

konektor that related to network card (lan card) and to konektor bnc and or to minator for end network.

Mengatasi Masalah Pada CD/DVD/ROM/RW

Gejala : Jenis kerusakan yang biasa ditemui :

1. Tidak terdeteksi di windows

2. Tidak bisa keluar masuk CD

3. Tidak bisa membaca/menulis/hanya bisa membaca saja. (CD)

4. Tidak bisa membaca/menulis/write protect (Floppy disk)

Solusi :

1. Periksa kabel data dan kabel tegangan yang masuk ke CD-floppy, perikas di setup bios apakah sudah dideteksi? sebaiknya diset auto. Periksa apakah led menyala, jika tidak kerusakan di Controllernya.

2. Kerusakan ada pada mekanik motor atau karet motor.

3. Kerusakan Biasanya pada optik, tetapi ada kemungkinan masih bisa diperbaiki dengan cara men-set ualng optik tersebut.

4. Head Kotor, bisa dibersihkan menggunakan Cutenbud
