The kit consists of an instruction manual and a die-cut cardboard "computer". The computer "operates" by means of pencil and sliding cards. Any arithmetic is done in the head of the person operating the computer. The computer operates in base 10 and has 100 memory cells which can hold signed numbers from 0 to ±999. It has an instruction set of ...
The Open-Source Lab: How to Build Your Own Hardware and Reduce Research Costs by Joshua M. Pearce was published in 2014 by Elsevier. The academic book is a guide, which details the development of free and open-source hardware primarily for scientists and university faculty. [1]
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 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.
Wang Laboratories, Inc., was an American computer company founded in 1951 by An Wang and G. Y. Chu. [1] The company was successively headquartered in Cambridge, Massachusetts (1954–1963), Tewksbury, Massachusetts (1963–1976), and finally in Lowell, Massachusetts (1976–1997).
Computer lab. While computer labs are generally multipurpose, some labs may contain computers with hardware or software optimized for certain tasks or processes, depending on the needs of the institution operating the lab. These specialized purposes may include video editing, stock trading, 3-D computer-aided design, programming, and GIS. [3]

In the 1990s, several freeware and other proprietary tools (both hardware and software) were created to allow investigations to take place without modifying media. This first set of tools mainly focused on computer forensics , although in recent years similar tools have evolved for the field of mobile device forensics. [ 1 ]
