How to increase your website or Blog traffic
Hello Friends, I am going to share Jingling 4.0.2 Auto China Traffic Bot which can increase your website or Blog traffic. As you know that this software is very hard to find free and full version on internet because mostly user asking you to pay money. But here you can get free of charges for download you just need to complete one survey.
Tutorial
how to use this Jingling 4.0.2 Auto China Traffic Bot
What is Hybrid Topology?
The hybrid topology is a type of network topology that is composed of one or more interconnections of two or more networks that are based upon different physical topologies
Note
- A Star ring network consists of two or more star topologies connected using a multistation access unit (MAU) as a centralized hub.
- A Star Bus network consists of two or more star topologies connected using a bus trunk (the bus trunk serves as the network's backbone).
What is Tree Topology?
Nodes in a tree are linked to a central hub that controls the traffic to the network. However not
every devices plugs directly into the central hub. The majority of devices connect to a secondary hub that in turn is connected to the central hub. The control hub in the tree is an active hub. An active hub
contains a repeater which is a hardware device that regenerates the received but patterns before sending them out. Repeating strengthens transmission & increases the distance a signal can travel.
Advantages Of Tree Topology:
• The distance to which a signal can travel increases as the signal passes through a chain of hubs.
• Tree topology allows isolating and prioritizing communications from different nodes.
• Tree topology allows for easy expansion of an existing network which enables organizations to configure anetwork to meet their needs.
Disadvantages of Tree Topology:
• If the backbone line breaks, the entire segment goes down.
• It is more difficult to configure and wire than other
topologies.

What is Mesh Topology?
- Topology in which each of the nodes of the network is connected to each of the other nodes in the network with a point-to-point link – this makes it possible for data to be simultaneously transmitted from any single node to all of the other nodes.
- The physical fully connected mesh topology is generally too costly and complex for practical networks, although the topology is used when there are only a small number of nodes to be interconnected
• Advantages:
• Fault tolerance
• Guaranteed communication channel capacity
• Easy to troubleshoot
• Disadvantages:
• Difficulty of installation and reconfiguration
• Cost of maintaining redundant link
• The cost of cabling all the hosts together is expensive
