The document discusses different types of data communication mediums. It describes wired mediums like coaxial cable, twisted-pair cable, and fiber optic cable. It provides details on the characteristics, advantages, and disadvantages of each. Coaxial cable can support speeds up to 200 Mbps but has a shorter transmission distance compared to other options. Twisted-pair cable is commonly used for telephone lines and network cables in buildings. Fiber optic cable is capable of speeds over 1 Gbps and has several advantages for long-distance, high-speed data transmission.
