					                              Using Packet Tracer Hub
1. Trial 1




Analysis:
Pictured above is one example of a computer simulation jaringn using cisco packet tracer
consisting of four PCs and one Hub-PT. any PC connected to the hub by using Copper
Straight-Trought. With each PC has the IP address specified.

2. Data transmission simulation
     Stage 1




      analysis:
       At this time we will try to simulate the delivery of data from PC0 to PC3 with a simple
       PDU on the Right Toolbar. The way the right of the toolbar select Add Simple PDU is
       illustrated envelope.
      Stage 2




analysis:
After selecting the Sample PDU on the toolbar and then drag and drop on PC0 and then drag
back to PC3.


      Stage 3




analysis:
After placing Sample PDU to be sent to the PC0 and PC3 then at a later stage we select
simulation mode in the lower right corner of the toolbar
      Stage 4




analysis:
After selecting the Simulation Mode looks like the picture above.
      Stage 5




analysis:
At a later stage to simulate the delivery of data from PC0 to PC3, we select the Auto capture /
Play. Then automatically sending the data will be simulated to determine whether or not the
data to the destination PC.
3. Trial 2




analysis;
Pictured above is a simulation of a computer network that is with 8 PCs, 2 Hub-Repeater PT
and one fruit. Computer networks are interconnected to each other anatar using Hpub-PT and
Repeater. Each PC has the IP address specified.




analysis:
Pictured above is one of the ping command at the Command Prompt PC0. ping 192.168.200.2
is the command to find out whether or not PC0 is connected to a PC that has the IP address.
analysis:
Ping command on the orders to try to test the connection to the IP address 255.255.255.255.
                                  Simulation of the Data
      Stage 1




analysis:
we will try to simulate the delivery of data from PC2 to PC7 by simple PDU on Right
Toolbar. The way the right of the toolbar select Add Simple PDU is illustrated envelope.
      Stage 2




Analsys:
After selecting the Sample PDU on the toolbar and then drag and drop on PC2 then drag back
to PC7.
      Stage 3




analysis:
After placing Sample PDU to be sent to PC2 and PC7 then at a later stage we select
simulation mode in the lower right corner of the toolbar
      Stage 4




analysis:
After selecting the Simulation Mode looks like the picture above.
      Stage 5




analysis:
At a later stage to simulate the delivery of data from PC2 to PC7 then we select Auto capture /
Play. Then automatically sending the data will be simulated to determine whether or not the
data to the destination PC.
The use of Bridge




analysis:
At this time we use the simulation as a liaison between the Bridge of computer networks to
one another.

Differences with Bridge Repeater
bridge
The bridges operate at both the physical layer or data link layer. In the physical layer
regenerates the function of the received signal. While at the data link layer device can check
the physical address (either the sender / source and receiver / destination) is in the packet data.
Bridge itself does not have a physical address and only serves as a filter, not the sender and
receiver devices.
repeaters
Repeater is a device that only operates on the physical layer. repeaters can extend the physical
distance of a network. Repeaters simply forward data packets, and do not have the ability to
filter them out.
Difference between the bridge and repeater is that the bridge has the ability to filter (sort /
select). Bridge can check the destination address on a packet of data and decide on the
package is forwarded or deleted. Nevertheless, the bridge does not change the physical
address contained in the package.

                                Spanning Tree Protocol (STP)
Spanning Tree Protocol abbreviated as STP, is part of the IEEE 802.1 standard for media
access control. Serves as a protocol for the connection settings by using the spanning tree
algorithm.
Excess STP system can provide backup path and also prevents undesirable loops in the
network that has multiple paths to an end of a host.
Loop occurs when there route / alternative paths between the hosts. To prepare the path back
up, STP makes the status line back up into stand by or diblock. STP allows only one active
path (loop prevention function) between two hosts, but set the path back up when the main
line is disconnected.
If the "cost" STP changed or there is an unbroken path, spanning tree algorithm to change the
spanning tree topology and activates pathways that were previously stand-by.
Without spanning tree was actually possible connection between two hosts through several
channels at once, but can also make a loop that never will be completed in your network. That
will surely spend the capacity of existing lines just to pass the same data packet repeatedly
and multiply.
