Transmission Media Used in New Office Setup

Students who are studying networking in Singaporean colleges or universities are asked to write homework or assignments related to data communication topics. Candidates search for assignment writing services in Singapore when running short of time.

If you require network assignment help, then the below provided essay sample would be of great benefit to you.

What is meant by transmission media?

Transmission media is an actual pathway used to transmit information or message from sender to receiver and vice versa. They are also known as communication channels through which an electrical signal Travels.It has two types

• Guided media– it is also called bounded or wired transmission media. Such as twisted pair cable, coaxial cable, or optical fiber cable
• Unguided media– it is also called unbounded or wireless transmission media such as infrared, microwaves, and radio waves.

Transmission media’s main purpose is to transport a bit of stream from one component to another. Various types of media can be used for actual data transmission.

What are the most commonly used transmission media in a new office setup?

For office network setup various transmission media to be used are discussed below

•  Local area network (LAN) – it is used to facilitate various independent devices to communicate with each other directly in a confined geographical area like a building, a factory, or an office.
•   Metropolitan area network (MAN) – it is designed to get extended over the entire City. For example, cable television. It connects LAN into the larger network. It can be owned by a single private or public company.
•  Wide area network (WAN)– it covers a larger geographical area that may include a continent, a country, or the whole world. It provides long-distance data transmission. For example, the internet covers the entire world.
•  Routers– they connect two or more segments by connecting networks through different architectures. They reduce network traffic by sending the packet to the desired destination.
• Bridges– it is used for connecting two or more networks. They are used to increase the network bandwidth by eliminating unneeded packets.
• Switches– it is a special type of switching hub used to minimize the traffic overwork segments. They are used to boost up crowded network speed. For example, switches, when used with Ethernet, are known as switched Ethernet.
•  Hubs– it has a fixed number of ports that connect the node network with topologies. It provides connectivity between nodes. Hubs are chained together which allows more nodes to be attached to the network.
• Repeaters– it connects to network segments through a device called an amplifier that boosts the signal strength. Repeaters can be used between various media types but not between network architectures.
• Wireless communication– it uses infrared (IR) or radio frequencies (RF) waves to transmit the data between various components. Pc or laptop will receive the signals through the access point by installing the wireless adapter card. 
• Twisted pair cable– these types of cables are used for telephone communications and Ethernet networks. Twisting the wires can cancel the magnetic field effect. It provides self-shielding for the wires within the network media.
•  Coaxial cable– it is used for longer distances for example, in LAN. It is inexpensive and supports 10 to 100 Mbps of data transmitting. It is known as a cheapernet because it is cheaper to install. 
• Fibre optical cable – it operates at high speed that is in gigabits. Signals are transmitted over longer distances without a need to be strengthened or refreshed. Universities, building. industrial plants or colleges use Optical Fibre.

Which transmission media is best?

Among all the transmission media studied above, the optical fibers are the most secured. Fibre optical cables have high bandwidth and greater transmission speed. The network signal can cover longer distances. It covers major countries and cities and has zero interference.

Conclusion

The main purpose of transmission media arose to connect all the networking devices to share video, data, and information. In the present times, there is a need for a transmission media which can transmit the data at a greater distance and a fast speed.

From the above discussion, we have seen various transmission media that are developed and used.

It depends upon the organization as to which transmission media they want to use depending upon their location, bandwidth, and budget. These kinds of topics become an important part of the discussion for the students who are studying information technology.
