Transmission media refers to the physical pathways that carry data from one computer or device to another. In simple terms, it's like the "road" over which data travels. These media can be either wired, such as cables made of copper, fibre optic cables, or wireless, using radio waves or infrared signals. Wired transmission, like twisted pair cables, are often used in networks within a building, while wireless transmission, like Wi-Fi, allows devices to connect without physical cables. Understanding transmission media is important because it affects the speed, distance, and reliability of data transfer in computer networks.
