Get to Know the Benefits of Intensive Farming?

Intensive farming is a method of maximum yield of producing plants or raising animals which relies mostly on the use of technologies like modern ploughing techniques, pesticides, and chemical fertilizers. Intensive farming is practiced widely by many developed economies of the world.

Following are some of the advantages of intensive farming:
  • By intensive farming, it is possible to achieve higher quality crops leading to higher profits.
  • It allows you to produce a larger amount than you would normally because you need only a small space or room to produce the plants or to raise the animals.
  • People can afford the price of food because the cost of producing the crop is less.
  • The same area of land can also be used to store food and fiber for supplying to the larger population reducing the risk of starvation.
  • If you use less space for keeping cattle, you need not to spend extra energy in moving from here to there.
  • The new method of indoor crop technology which controls climate conditions and neutralizes weather hazards, theoretically enabling year-round growth activity introduced the concept of intensive farming.
  • You can also control the flow of production while protecting the high quality of price year-round, ensuring the farmer a stable income flow.
  • In the case of intensive live stock farming, capturing methane emissions from it can be used to generate heat or electrical energy thereby reducing the local fossil fuels.
The preservation of existing areas of woodland and rainforest habitats (and the ecosystems and other sustainable economies that these may harbor), which would need to be felled for extensive farming methods in the same geographical location. This also leads to a reduction in anthropogenic CO2 generation (resulting from removal of the sequestration afforded by woodlands and rainforests).

Topology in Network Design

In a computer networking, topology refers to physical layout of devices or arrangement of the network, including its nodes and devises. In other words, in a networking how nodes are connected and how these are communicate is also called as network topology. Topology is either physical or logical. Physical topology is the actual geometric layout of workplaces; logical topology refers to the nature of the path signals follow from node to node.

Some physical topologies or arrangements of nodes in computer networking:
  • Bus topology: All devices are connected with a central cable.
  • Star topology: All devices are connected with central hub. Nodes communicate in network through the help of hub.
  • Ring topology: All devices connected with one another with a closed loop, here each device is connected with two more devises on each side.
  • Token ring: All devices connected with one another with a closed loop, but signals travel in one particle direction only.
  • Mesh topology: Devices are connected with many redundant interconnections between network nodes; here every device has connection with other.
  • Tree topology: Tree topology integrates multiple star topologies onto bus topology.
Topology is important in building a network design in homes or offices. This gives physical arrangement of devices in network workplace. Every topology has its unique advantages.
