2. Cable
* There are several types of cable being used and have become standard in its use for data communication in computer networks.
* Any type of cable has different capabilities and specifications.
* There are three types of cable in general is often used, namely:
o Coaxial
Twisted pair o
o Fiber Optic
3. Coaxial
* Thick Coaxial
o The average diameter of 12 mm
o The standard is called Ethernet / Ethernet thick / yellow cable
* Thin Coaxial
o The average diameter of 5 mm black
o Many used among radio amateurs, especially for transceiver that do not require a large power output.
o Every device connected to the BNC (Bayonet-Neill-aConcelmn) T Connector.
o It is called Thin Ethernet / Thin Net.
4. Thick Coaxial
* The specifications of the network:
* Each end must be terminated with a terminator 50 Ohm 1 watt.
* Maximum of three segments with the connected equipment or be populated segments.
* Every network card has an additional transmitter.
* Each segment contains a maximum of 100 network devices, including repeaters.
* Max cable length per segment is 1640 feet (± 500 meters)
* Max distance between segment is 4920 feet (± 1500 feet)
* Each segment must be grounded.
* Max distance between taps or branching from the main cable to the device is 16 feet (± 5 meters)
* Min Distance between taps is 8 feet (± 2.5 meters)
5. Thin Coaxial
* Every tip given 50 Ohm terminator.
* Maximum of three segments connected to each other (populated segments).
* Card transceiver network using the onboard enough, no need additional transceiver, except for the repeater.
* Each segment contains a maximum of 30 network devices.
* Max cable length is 606.8 feet (± 185 meters)
* Max cable length between the segment is 1818 feet (± 555 meters)
* Each segment must be grounded.
* Length between T min Connection is 1.5 feet (± 0.5 meters)
6. Twisted Pair Cable
* UTP (unshielded Twisted Pair)
* STP (shielded Twisted Pair)
* It consists of four twisted pairs of wires
* Of the eight pieces of existing cable, only four pieces are used to send and receive data.
* The other device relating to the use of this type of cable is a RJ-45 connector and hub / switch.
7. Twisted Pair Cable
* There are two types of UTP cabling that is commonly used, plus a special installation types for Cisco routers, namely:
o Straight Through Cable
o Cross Over Cable
o Roll Over Cable
8. Straight Through Cable
* Used to connect multiple computers through intermediaries HUB / Switch, which serves as consecrator or repeater.

9. Straight Through Cable
* The use of Straight Through UTP cable model in the local network typically will form a star or tree topology with the hub / switch as its center.
* Use of Hub / Switch should be in accordance with the speed of the NIC. Because the difference in speed on the NIC & Hub / Switch means both devices can not communicate optimally.

10. Cross Over Cable
* Different from Straight through, use a cross cable is used to communicate between computers (without HUB), or can also be used to cascade HUB if necessary.

13. Fiber Optic Cable
* Cables which have a core of glass fiber as a channel to distribute the signal between terminals BACKBONE often used as a channel for high reliability compared with coaxial cable or UTP cable. This cable is not affected by weather and heat.

14. Ethernet Card
* Ethernet Card working mode based on the broadcast network, where each node in the network receives each transmission of data sent by a node to another.
* Each Ethernet has over 48-bit address which is known as the Ethernet address (MAC Address).
* Address has been put into each set of network cards (NIC) that are recognized as the Media Access Control (MAC) or better known by the term hardware address. 24 bits or 3 bytes of the beginning of a code defined by the IEEE.
15. Ethernet Card
* NIC model have been generally 10Base port provides connections for coaxial cable or UTP cable.
* If it is designed for coaxial cable connectors are BNC.
* If it is designed for UTP cable is a RJ-45 connectors.
16. Hub & Switch
* Hub & Switch is usually called a concentrator.
* A concentrator is a device that unites the network cables from each workstation and server or other device.
* In a star topology, the UTP cable from a workstation into a hub or switch.
* Using the RJ-45 connectors
* Some type of hubs can be fitted multilevel (stackable) to four flats, and usually has a hole as much as 4, 8, 16 and 24 pcs.
* Switch is a concentrator that has the ability Traffic management data better than the Hub.
* Type of Switch manageable, besides can manage data traffic can also be given an IP address.
17. Repeater
* Main function is to amplify the signal by receiving signals from a wired LAN segment and then radiate back with the same power with the original signal at the other cable segments.
* In this way the distance the cable can be diperjauh.
18. Bridge
* Functions same as the repeater, but more flexible and more intelligent than the repeater.
* Bridge can connect networks using different transmission methods.
* Part of Bridge could separate from the Traffic because it implements the frame filtering mechanism.
* This mechanism is generally as store and forward.
* Bridge can be used to connect networks that use different types of cable or different topologies.
* Bridge can know the address of each computer on each side of the network.
19. Router
* Router can transmit data / information from one network to another different network.
Router * almost the same as the bridge, but not as smart, flexible bridge.
* Router will find the best path for sending a message based on the destination address and source address.
* Routers know addresses of each computer on the local network environment, address other bridges and routers.
* Router can know the whole network to see which side of the busiest and can pull data from a busy side to side is clean.
20. Router
* Able to translate information from the LAN and the Internet.
* Find the best alternative route for sending data through the Internet.
* Set the signal path can be efficiently manage data flowing between the two protocols.
* Able to manage data flow between the network topology of linear bus and star.
* Able to manage the flow of data through fiber optic cable, coaxial cable and UTP cable
