Types of Network Topology

Network topology refers to the physical layout of the network i.e. the locations of the computers and how the cable is run between them. To select the right topology for how the network will be used is very important. Each topology has its own strength and weaknesses.

The choice of a topology for installing a computer network depends upon a combination of factors such as, reliability, performance of the system, number of nodes and geographical distribution of the system.

The main 2 types are

Types of Network Topology

Bus Topology & Peer to Peer Topology

Peer to Peer topology consists of Star topology and Ring topology.

Bus Topology

It is often used when network installation is small, simple or temporary. On a typical bus network the cable is just 1 or more wires with no active electronics to amplify the signal or pass it along from computer to computer. This makes the bus a passive topology. When 1 computer send a signal up the wire all the computers receive the information but only one with the address that matches accepts the information, the rest disregard the message.

Advantages:

1) Easy to use and to understand.

2) Requires least amount of cable to connect the computers together. It is therefore less expensive than other cabling arrangements.

3) It is easy to extend a bus; two cables can be joined into 1 longer cable with a BNC, Barrel connector making a longer cable and allowing more computers to join the network.

Disadvantages:

1) Heavy network traffic can slow a bus considerably as only 1 computer can send a message at a time.

2) It is difficult to troubleshoot the bus. A cable break or loose connector causes reflection and stops all the activity.

Star Topology

In this kind of topology all the cables run from the computers to the central location where they are all connected by a device called hub or switch. Each computer on a star network communicates with a central device that resends the message either to each computer or only to the destination computer, e.g. if it is a hub then it will send to all and if it is a switch then it will send to only destination computer.When network expansion is expected and when the greater reliability is needed, star topology is the best.

Advantages:

1) It is easy to modify and add new computers without disturbing the rest of the network.

2) The center of the star network is a good place to diagnose the faults.

3) Single computer failure does not necessarily bring down the whole star network.

Disadvantages:

1) If the central device fails the whole network fails to operate.

2) Star networking is expensive because all network cables must be pulled to one central point, requires more cable than other network topologies.

Ring Topology

In this type each computer is connected to the next computer with the last one connected to the first. Each retransmits what it receives from the previous computer. The message flows around the ring in one direction. The ring network does not subject to signal loss problem as a bus network experiences. There is no termination because there is no end to the ring.

Advantages:

1) Each node has equal access.

2) Capable of high speed data transfer.

Disadvantages:

1) Failure of one computer on the ring can affect the whole network.

2) Difficult to troubleshoot the network.

Topologies remain an essential part of network design speculation. But understanding these can help you to get the deeper knowledge of the elements like hub, switch etc.

Dish Network Internet - What You Need to Know

As a stay at home mom with two small children and an online business to run, my days are pretty full. After the little ones go to bed, my husband helps me get merchandise ready to ship and I spend a couple of hours online, every night, building what I hope will one day become a hugely successful business.

When I first decided to pursue an Internet business, I spent a great deal of time making sure I chose the all the right ingredients that would give me the best chance for success. I did some research before choosing a hosting company for my website and finally selected one that guaranteed 99% uptime. If your site is down, your business is closed.

The problem I quickly discovered is that it doesn't matter how good the hosting company is or how much uptime they have if your Internet connection goes out! And mine did, over and over again, sometimes simply because it was raining, other times for no apparent reason at all. I complained repeatedly to my Internet provider and while they were apologetic, nothing was ever done to assure me that it wouldn't continue to happen.

Dish Network Internet - What You Need to Know

One day I was complaining about it to one of the women in my networking group and she told me how happy she was with her Internet access through Dish Network.

I finally found what I was looking for. All the information I needed to make an informed decision was presented in the most straightforward way possible.

I'm not saying you'll get the same deal I got, but I've included the link below so you can check it out for yourself.

You don't have to own an online business to benefit from Dish Network's Internet service. I was so pleased with our service that I told my mom and both my sisters about it. I gave them the same link you'll find at the end of this article. My sister Shelly lives on a farm so far from town that she's never even been able to get cable. But with Dish Network, she now gets more channels than cable even offers PLUS her Internet connection via satellite. She was absolutely thrilled to finally feel like she had joined everyone else in the 21st century.

In fact, it doesn't matter where you live; Internet access is available to you through Dish Network. They've partnered with Wildblue to provide Internet service to the most remote areas you can imagine. As long as you've got a spot with southern exposure Dish Network can bring the world into your home.

You don't have to take my word for it. Click on the link below, visit the site and decide for yourself. All I can tell you is that it was one of the best decisions I've made for my business.

Here is the basic rundown of the offerings of each service. For around per month, Dish Network offers a satellite package of 100 top channels with the local channels.

Another comparison that you will want to make is the price of the components that are needed to get the satellite programming.

For the most part, these components are offered free if you sign up for service for a particular length of time, but sometimes there is a rental fee that is associated with components, which can cause your monthly fee to be more than the programming cost.

Be sure that you read the fine print of your contract to be sure that you completely understand the terms, so that there will not be any surprises.
