What really happened with the Y2K bug?
What Really Happened in Y2K? Professor Martyn Thomas During the 1990s, the newspapers contained a growing number of stories and warnings about the Century Date Problem or “Millennium Bug” that would cause computers to fail at midnight on 1 January 2000. There were fears that there would be a power blackout and
What problems did the Y2K bug present?
The Y2K bug is a problem affecting older computers and other computer systems which store years using only the last two digits of the year; for example, 1980 is stored as 80.When this happens, many programs assume that the year is 1900 instead of 2000. This could cause some major problems when dealing with dates after January 1st, 2000.
Was the Y2K bug ever an actual problem?
Y2K bug, also called Year 2000 bug or Millennium Bug, a problem in the coding of computerized systems that was projected to create havoc in computers and computer networks around the world at the beginning of the year 2000 (in metric measurements, k stands for 1,000). After more than a year of international alarm, feverish preparations, and programming corrections, few major failures occurred ...

What is the Y2K problem?
The "Y2K Problem" includes a whole range of problems that may persist for several years and result from the way some computer software and hardware represent dates--hence the name "Y2 K," which stands for "Year 2000" (K is an abbreviation for "kilo," or 1,000). In short, because many computer systems store only the last two digits ...
What is the real problem with embedded processors?
Although there are many proposed solutions floating around, the real problem is that it is hard to imagine how all the systems that need fixing can be fixed in the necessary time frame. Moreover, in the case of the millions of embedded processors, it is unclear how the fix might be disseminated.
Why is it important to reuse the space allocated for a two digit date?
It turns out that this is possible because in many older databases, the numbers are stored using a fairly inefficient representation, called Extended Binary Coded Decimal Interchange Code (EBCDIC, pronounced "ehb-sih-dik").
Why Was Y2K Scary?
Experts feared that the switch from the two-digit year '99 to '00 would wreak havoc on computer systems ranging from airline reservations to financial databases to government systems. For instance, the banking system relied on dated computers and technologies and it wasn't irrational for depositors to worry about being able to withdraw funds or engage in important transactions. Bankers were worried that interest might be calculated for a thousand years (1000 to 1999) instead of a single day.
Why did Y2K happen?
Y2K came about largely due to economics. At the dawn of the computer age, the programs being written required the type of data storage that was extremely costly. Since not many anticipated the success of this new technology or the speed with which it would take over, firms were judicious in their budgets. This lack of foresight, especially given that the millennium was just about 40 years away, led to programmers being forced to using a 2-digit code instead of a 4-digit code to designate the year.
What Is Y2K?
Y2K is the shorthand term for "the year 2000." Y2K was commonly used to refer to a widespread computer programming shortcut that was expected to cause extensive havoc as the year changed from 1999 to 2000. Instead of allowing four digits for the year, many computer programs only allowed two digits (e.g., 99 instead of 1999). As a result, there was immense panic that computers would be unable to operate at the turn of the millennium when the date descended from "99" to "00".

What were the problems with Y2K?
The Federal Housing Administration reported minor Y2K related problems in three "mission-critical" systems. Two of these systems -- the Electronic Data Interchange (EDI), and Comprehensive Servicing and Monitoring System (CSMS) -- experienced problems which caused incorrect dates to appear on reports. These errors did not affect any other content of the reports however, so the bug was minor. The third system which experienced problems was the Single Family Insurance System (SFIS). This error prevented users from terminating FDHA mortgages. The results of these bugs were for the most part insignificant, and all were corrected promptly.
