Are you curious to know what is guided media? You have come to the right place as I am going to tell you everything about guided media in a very simple explanation. Without further discussion let’s begin to know what is guided media?

In the realm of computer networks, communication channels play a pivotal role in transmitting data from one point to another. Guided media, also known as wired or bounded media, form the backbone of these communication pathways. This article aims to provide a detailed understanding of guided media, its types, examples, and the distinctions between guided and unguided media.

What Is Guided Media?

Guided media, in the context of computer networks, refer to communication channels that use physical wires or cables to transmit data signals from one device to another. Unlike wireless communication, guided media provide a tangible pathway for data transmission, offering reliability and stability in network connectivity.

Understanding Guided Media With Example:

An example of guided media is a coaxial cable used in Ethernet networks. The coaxial cable serves as a guided medium, transmitting data signals between network devices such as computers, routers, and switches.

Exploring Types Of Guided Media:

  • Twisted Pair Cable: Consists of pairs of insulated copper wires twisted together, commonly used in Ethernet networks for data transmission.
  • Coaxial Cable: Features a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer. It is widely used in cable television and broadband internet connections.
  • Optical Fiber Cable: Utilizes strands of glass or plastic fibers to transmit data signals using light pulses. Optical fiber cables offer high-speed, long-distance communication and are commonly used in telecommunications and internet backbone networks.

Difference Between Guided And Unguided Media:

  • Guided Media: Utilizes physical wires or cables to transmit data signals, offering reliability and stability in communication.
  • Unguided Media: Relies on wireless signals, such as radio waves or microwaves, for data transmission. Unguided media include wireless networks, satellite communication, and infrared transmission.

Guided And Unguided Media Examples:

  • Guided Media Example: Twisted pair cables, coaxial cables, and optical fiber cables are examples of guided media commonly used in computer networks.
  • Unguided Media Example: Wireless networks, satellite communication, and Bluetooth technology are examples of unguided media that rely on wireless signals for data transmission.

Guided Media And Unguided Media In Computer Network:

In computer networks, both guided and unguided media play essential roles in establishing communication channels. Guided media offer reliability, high bandwidth, and security, making them suitable for wired network infrastructure. Unguided media provide flexibility, mobility, and scalability, catering to wireless communication needs in modern networks.


Guided media form the cornerstone of wired communication infrastructure in computer networks, offering reliability, stability, and high-speed data transmission capabilities. By understanding the types, examples, and distinctions between guided and unguided media, network administrators can make informed decisions when designing and implementing communication pathways.


What Is Unguided Media?

Unguided transmission media are methods that allow the transmission of data without the use of physical means to define the path it takes. Examples of this include microwave, radio or infrared.

What Is Guided Media Wikipedia?

Guided media refers to any medium that can be directed from transmitter to receiver by means of connecting cables. In optical fiber communication, the medium is an optical (glass-like) fiber. Other guided media might include coaxial cables, telephone wire, twisted-pairs, etc…

What Do You Mean By Transmission Media?

What is Transmission Media in Computer Network? Transmission media is a communication channel that transmits information from the source/transmitter to the receiver. It is a physical path for data transfer through electromagnetic signals. Information is carried over in the form of bits through LAN.

Is Air A Guided Media?

Transmission media are categorized into two groups:

Guided media: Guided media include cables. Unguided media: Unguided media include waves through air, water and vacuum.
