Burner is a device to convert digital signals to: (A) analog signal disc (B) broadband carrier (C) optical laser disc (D) video switcher Correct Ans: (C) Explanation: A burner converts digital signals into optical laser discs. It uses a laser to write data onto a disc, such as a CD, DVD, or Blu-ray. The laser creates light and dark spots on the surface of the disc, which represent binary code. Optical drives can read these spots, allowing them to interpret the data. The burner encodes digital files, such as music, videos, and documents, into a format that compatible devices can play or access. It enables users to back up, transfer, and share digital content easily. The optical laser disc serves as a storage medium, allowing users to store large amounts of data. Before the rise of USB drives and cloud storage, this technology played a crucial role in media distribution and data storage. Thus, the burner helps in converting and storing data for various applications.
