The storage of computer programs is key to the operation of modern computers and is the connection between computer hardware and software. [7] Even prior to this, in the mid-19th century mathematician George Boole invented Boolean algebra —a system of logic where each proposition is either true or false.
A programmable hardware artifact, or machine, that lacks its computer program is impotent; even as a software artifact, or program, is equally impotent unless it can be used to alter the sequential states of a suitable (hardware) machine. However, a hardware machine and its programming can be designed to perform an almost illimitable number of ...
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
The first version was introduced with PowerPoint 3.0 in 1992, to enable electronic presentations to be projected using conference-room computers and to be freely distributed; on Windows, it took advantage of the new feature of embedding TrueType fonts within PowerPoint presentation files to make such distribution easier.

The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive.
The first microcomputer-based presentation software was Cromemco's Slidemaster, developed by John F. Dunn and released by Cromemco in 1981. [2] [3] [4] The first software displaying a presentation on a personal computer screen was VCN ExecuVision, developed in 1982. This program allowed users to choose from a library of images to accompany the ...
