Types of Computer Network Topology

1. Bus Topology

This topology is that the initial topology used to connect computers. In this topology each computer will be connected to a long cable with multiple terminals, and at the end of Cable must end with a terminator.
This topology was originally used as a medium of instruction Coaxial Cable data and information. But at this point in building this topology in computer network using a cabal of optical fiber (fiber optic) but combined with other network topologies to maximize performance.

2. Ring Topology

Atay ring topology is often called a ring topology is a network topology where each computer connected to the circle. With the sense that every computer connected into one network inter-connected to two other computers so as to form a network similar to the shape of a ring.
The advantages of this topology is the cable used can be more conserved. But the shortcomings of this topology is the development of the network will be difficult because each computer will be connected to each other.

3. Token Ring Topology

This topology is similar to the ring topology will be more in the making but perfected.
In the picture clearly seen how the token ring interface Cable made ​​into a cycle of advance and will be at the Make the terminals for each of the computers and other devices.

4. Star Topology

Or star topology is more often called star topology. In this topology we have used the help of other tools to connect computer networks.
On a clear picture serves as a central hub connecting the computers that are interconnected. The advantage of this topology is very much at ease among admins to manage the network, facilitate the addition of computers or terminals, ease of detecting damage and faults on the network. But with many of its advantages in terms of topology this is not without flaws. The drawback to such a waste of cable, the controls are centralized at the hub sometimes be a critical issue that in case of damage to the hub then all of the network will not be in use.

5. Tree Topology

Topology tree or hierarchical topology also called and can also be called multilevel topology is a topology that can be used on the network in a multilevel indoor office.
In the figure we can see the relationship between one computer to another computer with a hierarchical branching jelas.sentral center or who are at the very top of an active central central while below it is a passive central.

UTP Cable Crimping Method




Step By Step UPT Cable Crimping Method:




1. Before making the cable we need to peel out of utp cable during stripping about 1 inch from the end of his order at the time of mounting RJ45 crimping can result in a good and strong.





2. Sure at the time of peeling the outer wires of the cable wires are not in any order within a cable can be connected to either cut or scratched if it is in the early going well but after some time will be damaged and no longer connected



3. After peeling the outer cable is the next step and separate the wires in alignment on each cable so the crimping cable Pls That Produce berkualitas.pisahkan the orange wire to the left and right color of brown and then We separate the pair of green and white color green green. white to the left


and green to the right then stay to parse the blue pair in the middle so That the decomposition process Easier and more efficient cables.


4. We have to straighten each wire conductor into a sequence that complies with the standard cable pengkabelan.bagaimana sequence? standard cable in the call sequence with the sequence 568-B for a more clear cable can be viewed below is clear on the arrangement of the cable conductor on each type of wiring topology, there is for straight cable and crossover cable, if it is clear we go to step 5.




5. The next step we cut all the cable conductors in Squeeze your way all the cables that had been in alignment try to cut it flat with a 90 degree angle about 1 / 2 inch from the outside wires, do not cut the cable is too short so that it will be gripping the conductor contacts on the RJ45 .

6. The next steps include conductor cable to make sure the RJ45 cable conductor in order to firmly hold the cables do not experience a shift in the composition of the cable (not flat) and input cable with the orange color of the initial order from the left and input to the RJ45.

7. Get in on lawyer-stage crimpingan.pada this stage be sure re-enter the results of the cable into the RJ45 cable and try and push up into the RJ45 contacts on each conductor cable and press the tool crimpping to read "click" on the RJ45.

8. If it is on the cable end of the first to do way over to repeat his or her needs kedua.jika cable ends are straight arrangement of the first cable equal right with the second cable, if you need a crossover cable descriptions distinguish it as the following example:


like the picture above if you want to make a straight wire of each cable end with an array of straight and if you want to make a crossover cable using the composition of the first straight edge and the second end using a crossover.
