What are the commonly used wired media and wireless transmission media in computer networks, and their features are briefly described
From the comparison of anti interference and price, between the twisted pair coaxial cable between the optical fiber and the optical fiber; optical signal attenuation has advantages of small, high bandwidth and strong anti-jamming capability. The wireless transmission medium is through electromagnetic wave propagation in the atmosphere.
Cable medium: twisted pair, coaxial cable and optical fiber. Wireless transmission medium: microwave, infrared ray, laser or satellite. Cable medium twisted pair wire is low in price and low in transmission speed;
