MCQ on Cables and Connectors | Electrical Engineering MCQs: Cables are physical media used to transmit signals, power, or data between devices. They consist of one or more conductors, which are typically made of metal, encased in an insulating material to prevent electrical interference and ensure proper transmission.
Cables come in various types and configurations depending on their intended use. Types of cables:
1. Ethernet Cables: These cables are used for networking and connecting devices such as computers, routers, and switches to establish a wired internet or local area network (LAN) connection.
2. Coaxial Cables: Coaxial cables are commonly used for cable television (CATV) and broadband internet connections.
3. USB Cables: Universal Serial Bus (USB) cables are used for connecting devices like computers, smartphones, printers, and other peripherals. They are commonly used for data transfer and charging purposes.
4. HDMI Cables: High-Definition Multimedia Interface (HDMI) cables are used to transmit high-quality audio and video signals between devices such as TVs, monitors, and multimedia devices.
5. Power Cables: Power cables, also known as power cords, are used to provide electrical power from a power source (such as a wall outlet) to devices like computers, appliances, and electronic equipment.
6. Audio Cables: Audio cables are used for transmitting analog or digital audio signals between audio devices such as speakers, headphones, microphones, and audio interfaces.
7. Optical Cables: Optical cables, also called fiber optic cables, use light signals to transmit data over long distances at high speeds. They are commonly used in telecommunications, networking, and audio/video applications.
