What is the Y2K or Y2K bug?

Answer 1

Y2K simple means year 2 thousand.

y=year

2=2

k=1000 (kilo), in the metric system k is representative of 1000. for example, 1 Km is equivalent to 1000m.

When we approached the year 2000, it was thought by many that many of the world's computers would not have the capability to switch over from 1999 to 2000. Many people stocked up on non-perishables in fear of the world shutting down because of this.

However, nothing happened.

Many people believe that it is the year 2001, not 2000, that would create such panic that was created by Y2K, because we started counting (records begin) at year 1, not year '0'.

Again, however, nothing happened.

Answer 2

In the 1960s and 1970s, computer space was expensive. One cost-cutting measure was to render the year as two digits instead of four. So, for example, a computer would recognize the year 1974 as just "74". The year 1999 would be recognized as "99", but happens after that? Well, it would roll over to "00" and mistake the year 2000 for the year 1900. Therein lies the bug.
