COMPUTER FUNDAMENTALS

Detailed explanation-1: -Lotus 1-2-3 is a discontinued spreadsheet program from Lotus Software (later part of IBM). It was the first killer application of the IBM PC, was hugely popular in the 1980s, and significantly contributed to the success of IBM PC-compatibles in the business market.

Detailed explanation-2: -A long lost native Unix version of the killer PC spreadsheet has not only been rediscovered, but almost unbelievably, it’s been updated to create a native Linux version. Lotus 1-2-3 was arguably the single application which made the IBM PC a success, and was launched nearly 40 years ago, on January 26, 1983.

Detailed explanation-3: -Does Lotus 1-2-3 still exist? IBM discontinued sales of Lotus 1-2-3 in 2013. This spreadsheet program is no longer available.

Detailed explanation-4: -> Google Sheets vs Microsoft Excel However, when Microsoft came out with its GUI-based products in the early 1990s, such as Excel, it left Lotus-1-2-3 out in the cold. Lotus was slow to respond to the disruptive new products, and despite being purchased by IBM in 1995, never really recovered.
