answer :
1. Bus topology : is a topology that uses one cable and connects to all pc
Excellence bus topology :
-Does not require widespread cable resources
-The cost is also cheaper than other topologies
-not too complicated if we want to increase network coverage
-Very simple.
Deficiency bus topology :
-Not suitable for heavy traffic (traffic)
-It is very difficult to troubleshoot the bus
-Slower than other topollogies
2. Star topology : the topology of its star-shaped arrangement
Excellence star topology :
-Its easy to change and add computers to a network that uses a star topologi without
interrupting the on going network activity.
-If one computer is damagd in network then the computer will not make the whole network
star dead
-We can use several typs of cables inside the same network with hubs that can
accommodate different types of cables.
Deficiency star topology :
-Has one fault point, located on the hub. If the central hub fails, then the entire network will
fail to operate.
-Need more cable because all network cables have to be pulled to one central point, so
more need more cable than network topology
-The number of terminals is limited, depending on the port on the hub.
-Dense data traffic can cause the network to work more slowly.
3.Ring topology : The topology is connected in a circle or ring and its current is
clockwise
Excellence ring topology :
-Data flows in one direction so that the occurrence of collisions can be avoided.
-The data stream flows faster because it can serve data from the left or right of the server.
-Can serve a dense flow of data traffic, because data can move left or right.
-Time to access data more optimally.
Deficiency ring topology :
-If there is one computer in the ring that fails to work, it will affect the whole network
-Adding or reducing the computer will disrupt the network.
-It's hard to reconfigure.
4.Mesh topology : is a combined topology of Ring and Star topologies
Excellence mesh topology :
-The main advantage of using mesh topology is fault tolerance.
-capacity of the comunication channel is guaranted, because has more relation.
-It is relatively easier to do troubleshoot.
Deficiency mesh topology :
-Difficult at the time of installation and reconfiguration when the number of computers and
connected equipment is increasing in number.
-The cost is great for maintaining excessive relationships.
5.Tree topology : is is a combination of several star topologies associated with the bus
topology
Excellence tree topology :
easy to find an error and also easy to make network changes if needed.
Deficiency mesh topology :
using lots of wires, frequent collisions and slow, if errors occur in high-level networks, then
low-level networks will be disrupted as well
6.Extended topology : is an advanced development of star topology where its
characteristics are not much different from star topology
Excellence extended topology :
If one sub node cable is disconnected then the other sub node is not disturbed, but the
attention of the central node is interrupted then all nodes in each sub node will be
disconnected
Deficiency extended topology :
Unable to use "low" cables because they only handle one traffic node, because to
communicate between one node to another requires several hops.
2. topologi jaringan kominfo :
is a combination of computer technology ('computing') and Internet-based development ('cloud'). Cloud (cloud) is a metefora of the internet, clouds are often depicted in the computer network diagram.
* swicth
devices used to connect computers or routers in a limited area, switches also work on the data link layer, how switches work almost the same as bridges, but switches have a number of ports so often called multi-port bridges.
* router
network devices used to divide the protocol to other network members, with the router then a protocol can be shared to other network devices.
3. Basic setting mikrotik
ip example from internet:
IP address: 192.168.200.21
interfaces: ether1
subnet mask: 255.255.255.0
gateway: 192.168.200.1
DNS: 8.8.8.8 - DNS google, may use DNS speedy.
Example of local IP to be applied in mikrotik:
IP address: 192.168.100.1
interfaces: LOCAL
subnet mask: 255.255.255.0
1. reset the mikrotik configuration
- sytem - reset configuration
mikrotik will restart.
login again, routerOS default configuration will appear select remove configuration.
2. go to interfaces, in the interface list field there are ether1-ether5.
now we will rename ether1 and ether2. I renamed ether1 to "wan" and ether 2 became "local"
this is optional to do / not.
3. create address
Click IP - addresses, create two addresses as follows
address: 192.168.200.21/24, interface: wan
click, IP - route - create new - gateway fill in 192.168.200.1
5. create local address
address: 192.168.100.1/24 interface: local
do as number 3.
6.setting DNS
I use google DNS, click IP-DNS, fill in 8.8.8.8
7. NAT settings
This nat works for local ip can be used for internetIP - firewall - nat - create new
in the general tab make sure the chain select "srcnat". chain: srcnat
then click the action tab
action select "masquerade".
7. DHCP server settings
Dhcp server is used for the client connected with mikrotik get ip dynamic.IP -> DHCP Server -> DHCP Setup
DHCP Server Interface: local
