_________media, also called wireless, provide a means for transmitting electromagnetic waves but do not guide themQuestion 2Answera.Unduidedb.Guardedc.Guidedd.Unguided

Highlight Instance of Guided Transmission Mediaa.NFC (Near Field Communication): Short-range wireless communication technology used for contactless payments, data exchange between devices in close proximity.b.Similar to fiber optic cable but without the protective covering. Used in short-distance, high-speed data connections, such as within data centersc.Coaxial Cable: Consists of a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer.d.Uses infrared light for short-range communication. Often used in remote controls, some short-range data transfer applications, and IrDA (Infrared Data Association) communicatione.Similar to fiber optic cable but without the protective covering. Used in short-distance, high-speed data connections, such as within data centers.f.Twisted Pair Cable: Consists of pairs of insulated copper wires twisted together. Commonly used in telephone lines and local area networks (LANs).g.Communication via satellites in geostationary or low Earth orbit. Used for television broadcasting, long-distance communication, and global positioning systems (GPS).h.Electromagnetic waves with higher frequencies than radio waves. Used for point-to-point communication over long distances, such as in microwave communication towers.i. Electromagnetic waves used for wireless communication. Commonly used in radio and television broadcasting, as well as Wi-Fi networks.j.Fiber Optic Cable:Uses thin strands of glass or plastic to transmit data using light signals. Offers high bandwidth and is immune to electromagnetick.Bluetooth:Short-range wireless technology used for connecting devices such as smartphones, laptops, and peripherals
