Q. Codec refers to ?

  • (A) Coder-decoder
  • (B) Co-declaration
  • (C) Command declaration
  • (D) Command decoding
✅ Correct Answer: (A) Coder-decoder
Explanation: A codec (short for coder-decoder or compressor-decompressor) is a device or software that encodes and decodes digital data, typically for audio, video, or multimedia applications.

Explanation:

1. Encoding (Compression): Converts raw data (e.g., video or audio) into a compressed format to save storage and bandwidth.


2. Decoding (Decompression): Converts the compressed data back into its original or a playable form.



Examples of Codecs:

Audio Codecs: MP3, AAC, FLAC

Video Codecs: H.264, H.265 (HEVC), VP9


Thus, the correct answer is (A) Coder-decoder because a codec performs both encoding and decoding functions.
