The Lotus Development Corporation was founded by Mitchell Kapor, a friend of the developers of VisiCalc. 1-2-3 was originally written by Jonathan Sachs, who had written two spreadsheet programs previously while working at Concentric Data Systems, Inc. To aid its growth, in the UK, and possibly elsewhere, Lotus 1-2-3 was the very first computer software to use television consumer advertising.
1-2-3 was released on January 26, 1983 and immediately overtook Visicalc in sales. Unlike Microsoft Multiplan, it stayed very close to the model of VisiCalc, including the “A1” letter and number cell notation, and slash-menu structure. It was cleanly programmed and relatively bug-free, as well as speed gained from being written completely in x86 assembly language (this remained the case for all versions until 4.0 when Lotus switched to C) and wrote directly to video memory rather than use the slow DOS and/or BIOS text output functions.

This reliance on the specific hardware of the IBM PC led to 1-2-3 being utilized as one of the two litmus test applications for true 100% compatibility when PC clones started to appear in the early- to mid- 80s. 1-2-3 was used to test general application compatibility, with Microsoft Flight Simulator being used to test graphics compatibility. Because spreadsheets use large amounts of memory, 123 spurred the drive for greater RAM capacities in PCs and especially the event of “expanded memory” which allowed greater than 640k to be accessed.

Lotus 123 became the first “killer app” for PC compatibles, especially as it was available exclusively on that platform and no other computers. Many thousands of PCs were sold solely for the purpose of running 123, and its near-monopoly of the spreadsheet market remained unchallenged for a decade.
There are different kinds of spreadsheets. The spreadsheets fulfill the same requirements but have different ways of ensuring that what is supposed to accomplish is accomplished. Examples of spreadsheets that are common and have certain difference in the way that they operate are the Excel and Lotus 1-2-3.

One of the common differences that exist between the Excel and Lotus 1-2-3 is the command structure and its application. In the case of Lotus 1-2-3, the command is chosen first.

The computer program Lotus 123 was created by Lotus Software in 1983. Lotus is now owned by IBM and is no longer made. Lotus Notes can be a stand-alone data repository, a front-end to numerous other data repositories, or many things in-between. What is a Notes Database. A Lotus Notes database generally has a file extension of '.nsf'. Within that file, there can be data, design elements, and programming code. Each database file also has its own security in the.
Lotus 1-2-3 was one of the first applications that made IBM's original PC a serious business tool, but it fell by the wayside due to poor coding decisions, failure to adapt, and the crushing tactics of Microsoft. Back in the late 1970s and 80s, the software that really sold the business community on personal computing was spreadsheets. Lotus 1-2-3 was the first innovative spreadsheet for the PC and was launched with a huge marketing campaign. Its ability to function like a simple database was unique, and turning data into a chart.
After which the range that the command should take effect is specified. On the other hand, Excel allows to choose the cell or range or object that then command is supposed to work on or to perform a function and then the command is applied. For example when a range of cells are to be formatted, in Excel the cells are highlighted and then the command is applied (Howard 2006, p. 56).

Another unique difference is the way the worksheet is moved around when it comes to Excel and Lotus 1-2-3. In the case of Lotus 1-2-3, when the HOME key is pressed, the cell which is in the upper-left corner of the worksheet in question is selected. In the case of the Excel, the first cell that is of the current row is highlighted. However, the navigation keys that are used in Excel can be moved around the worksheet like the way that the Lotus 1-2-3 operates (Howard 2006, p. 58).
Therefore, the common differences between the two spreadsheets are the commands and navigation. Lotus 1-2-3 calls for the command before selecting the cells while Excel supports the command after the selection. Moreover, they both posses different means in which navigation between the cells is accomplished.
