What is y2k meaning?

Y2K, also known as the Year 2000 problem or Millennium bug, was a computer programming issue that occurred as the year 2000 approached. Many computer programs and systems used only two digits to represent the year, i.e., "99" instead of "1999." This design flaw threatened to cause errors and system failures when the year 2000 arrived, leading to fears of a global economic and societal collapse.

To address the Y2K issue, companies and organizations around the world invested billions of dollars to update their computer systems and software. Governments also took measures to prepare for potential disruptions in essential services such as power grids, transportation, and banking systems. Despite these efforts, some minor glitches and outages occurred, but the feared widespread catastrophe did not materialize.

Overall, the Y2K problem highlighted the importance of maintaining and updating technology systems to prevent future issues.
