Sure, I can explain wired transmission media and wireless transmission media in detail.
Wired transmission media refers to the physical cables and wires used to transmit data signals between devices. Examples of wired transmission media include coaxial cables, twisted pair cables, and fiber optic cables.
1. Coaxial cables: These cables consist of a copper conductor surrounded by insulation, a braided metal shield, and an outer cover. They are commonly used for cable television and internet connections.
2. Twisted pair cables: These cables contain pairs of insulated copper wires twisted together. They are widely used for Ethernet connections in homes and offices.
3. Fiber optic cables: These cables use thin strands of glass or plastic to transmit data using light signals. Fiber optic cables offer high-speed data transmission and are commonly used in long-distance communication networks.
On the other hand, wireless transmission media does not require physical cables for data transmission. Instead, it uses electromagnetic waves to transmit data through the air. Examples of wireless transmission media include:
1. Radio waves: Wi-Fi networks and Bluetooth devices use radio waves for wireless communication. Radio waves have a longer wavelength and can pass through obstacles like walls.
2. Infrared waves: Infrared technology is used for short-range communication, such as TV remote controls. Infrared waves have a shorter range compared to radio waves.
3. Microwave transmission: Microwave signals are used for long-distance communication, such as satellite communication and cellular networks. They have a higher frequency than radio waves.
Wireless transmission media offer the advantage of mobility and flexibility but may be susceptible to interference and security risks. Wired transmission media, on the other hand, provide more reliable and secure connections but may be less flexible in terms of mobility. Both types of transmission media play crucial roles in modern communication systems, each with its own set of advantages and limitations.
Answer:
Wired media:-
Guided media are also known as wired or bounded media. These media consist of wires through which the data is transferred. Guided media is a physical link between transmitter and recipient devices. Signals are directed in a narrow pathway using physical links.
Wireless media:-
Wireless communication is also referred to as Unguided Media or Unbounded transmission media. In this mode, no physical medium is required for the transmission of electromagnetic signals. In wireless communication, we can transfer our message through the air, water or vacuum i.e. Infrared, Radio wave, Microwave wave.
