Transmission Media in Computer Networks:

-

 

Transmission Media:

Transmission media is a medium that carries data from one device to another. It is a physical channel that helps to transmit data from transmitter to receiver. This physical channel can be wired or wireless, where data gets transferred in the form of electromagnetic signals.

What are the characteristics of transmission media in Computer Networks:

The following are some of the characteristics of transmission media- 

  • Bandwidth: Bandwidth is the amount of data transmitted in a given time. Higher bandwidth implies a higher data transfer rate.
  • Transmission Distance: It refers to the maximum distance data can travel. Different media have different transmission distances; hence it is a factor to be considered to prevent data loss.
  • Interference: The presence of unwanted signals is known as interference. Different media have different levels of tolerance to unwanted signals.
  • Cost: Cost also varies depending upon the type of media used.

Transmission media types in Computer Networks: Explained:


There are two kinds of transmission media in computer networks: 

  1. Guided
  2. Unguided Media

Guided and Unguided media are sub-categorized.







What is Guided media in computer networks:

Guided media is a communication medium that uses a physical medium to transmit signals from sender to receiver. It is also referred to as wired media.

Gigabit Ethernet is key when there is a mine of information

Continuous, reliable communications are essential for the success of mining operations. They enable the transfer of crucial information across facilities, ensuring that fans, pumps, conveyors, and other key pieces of equipment operate correctly. When ineffective communications led to an increase in downtime at a mining complex in Mexico, CC-Link IE network technology offered a solid solution. When the (broadcast) storm is coming The facility utilises a Mitsubishi Electric MELSEC iQ-R PLC platform to control 35 variable frequency drives (VFDs), which in turn modulate the speed of fans, pumps and conveyors. While the automation components have been operating successfully for years, the mining complex was experiencing prolonged downtime associated with network failure. More precisely, approximately 20 hours were lost every month because of broadcast storms, data packet collisions, intermittent or even lost communications between enterprise level software and field devices. To address the

Network Virtualization

Network virtualization is a process of separating the functions of a network into different components, such as the physical infrastructure and management and control software and allowing those functions to operate separately. In this process, the software is used to emulate the functionality of hardware components that are commonly part of a traditional network. Network services are decoupled from the physical hardware they run on. They can be used independently, making them perfect for any network device. With this shift to programmable networks, we can more flexibly provision networks, more securely manage them, and programmatically and dynamically manage them. Network virtualization simplifies life for network administrators by making it easier to move workloads, modify policies and applications, and avoid complex and time-consuming reconfigurations when performing these tasks. In addition, customers and business people need instant access to various content, services, and informa
