  • Q1. Full form of PN Junction DIode.
  • Ans. 

    PN Junction Diode stands for Positive-Negative Junction Diode.

    • PN Junction Diode is a semiconductor device formed by joining a P-type semiconductor with an N-type semiconductor.

    • It allows current to flow in one direction only, from the P-type region to the N-type region.

    • Commonly used in rectifiers, voltage regulators, and signal demodulation.

    • Example: 1N4148 is a popular PN Junction Diode.

  • Answered by AI
  • Q2. Full form of DV
  • Ans. 

    DV stands for Digital Video.

    • DV is a format used for recording and playing back digital video.

    • It is commonly used in camcorders and digital cameras.

    • DV files have a .dv file extension.

    • DV video has a resolution of 720x480 pixels for standard definition or 720x576 pixels for PAL systems.

  • Answered by AI
  • Q3. What is tdl in memory testing
  • Ans. 

    TDL stands for Test Data Load in memory testing, used to load test data into memory for testing purposes.

    • TDL is a process in memory testing where test data is loaded into memory to simulate real-world usage scenarios.

    • It helps in identifying memory leaks, performance issues, and other memory-related problems.

    • Examples of TDL tools include MemTest86, RAMMon, and MemTest.

  • Answered by AI
  • Q4. What is diffrence between xor and elastic codec
  • Ans. 

    XOR is a logical operation that outputs true only when inputs differ, while elastic codec is a compression algorithm used in video streaming.

    • XOR is a logical operation that outputs true only when inputs differ

    • Elastic codec is a compression algorithm used in video streaming

    • XOR is commonly used in cryptography for encryption purposes

Interview Preparation Tips

Interview preparation tips for other job seekers - Prepare for best and expect the worst in terms of interview experience. HR management is worst and they'll keep finding replacements of yours even after selecting. So you should also have plan B incase your candidature gets rejected. I declined the offer and joined another company.
