GDB Topic

A group of 12 scientists are going to conduct a research about the germs like Ebola, dangi etc. These scientists are supposed to travel from one location to another in their research study. When they will find the outcomes, research will be shared to the entire scientist’s community in the world.

In order to work efficiently and quickly they are going to build a computer network. Some characteristics of their network are given:

  • ·         The scientists can share their ideas and research work with other scientists
  • ·         The network can easily be build
  • ·         The network can be easily extendable
  • ·         Cost of the network can be low
  • ·         The network should be easy to maintain

Keeping all the above points in your mind, which type of network topology you will suggest for the group of scientists? Briefly explain with solid reasons.

GDB will open on 16/02/2017 and will remain open for 2 days.

Note 1: Keep your answer precise.

Note 2: All times are according to Pakistan Standard Time (PKT)

Note 3: GDB will not be accepted via email and in regular MDB so post your GDB answer only in GDB.

Star topology i will suggest for the group of scientists because:
Every workstation is indirectly connected to every other through the central computer. Centralized management of the network, through the use of the central computer, hub, or switch.
If one computer on the network fails, the rest of the network continues to function normally.
The star network topology works well when workstations are at scattered points. It is easy to add or remove workstations.

But Star topology is expensive than bus topology.

but it is not inexpeincy??

Please Discuss here about this GDB.Thanks

I think, STAR Topology. Due to ease of installation, maintenance and extending ability.

I suggest Star topology for the group of scientists because  every computer is connected to another  computer through the central device Hub.

I would suggest bus topology for this network because it poseses all intended requirements. Its cost effective, easy to build and maintain, easy to expand etc

According to requirements , kuch samj nhi aa rha. kya choose krna hy...? anyone help.....!

STAR TOPOLOGY
Star topology is better for other types of topology. A star topology is a topology for a Local Area Network in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e. g a bus but the benefit is that if a cable fails, only one node will be brought down. It is very useful for the group system. Every workstation is indirectly connected to every other through the central computer. In some star network, the central computer can also operate as a workstation.
All traffic emanates from the hub of the star. The central site is in control of all the nodes attached to it. The central hub is usually a fast, self contained computer and is responsible for routing all traffic to other nodes. The main advantage of a star network is that one malfunctioning node does not affect the rest of network. However this type of network can be prone to bottleneck and failure problems at the central site. A star network is often combined with a bus topology. The central hub is then connected to the backbone of the bus. This combination is called a tree.
Advantages of the star topology
1. If one node or its connection breaks it doesn’t affect the other computers and their connection.
2. Devices can be added or removed without disturbing the network.
3. Centralized management of the network through the use of the central computer hub or switch.
4. Easy to add another computer to the network.
5. If one computer on the network fails, the rest of the network continues to function normally.

Metropolitan Area Network

A metropolitan area network (MAN) is a network is a network that interconnect users with computer resources in a geographically area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).

  A metropolitan area network, or MAN, consists of computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a signal building or site. Depending on the configuration, this type of network can cover an area from several miles to tens of miles. A MAN is often used to connect several LAN’s together to form a bigger network. It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.  A MAN is used to connect several LANs together to form a bigger network. When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN.
