An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics.
A Pocket PC is a class of personal digital assistant (PDA) that runs the Windows Mobile or Windows Embedded Compact operating system that has some of the abilities of modern desktop PCs. The name was introduced by Microsoft in 2000 as a rebranding of the Palm-size PC category. Some of these devices also had integrated phone and data capabilities, which were called Pocket PC Phone Edition. Windows "Smartphone" is another Windows CE based platform for non-touch flip phones or dumber phones.
A graphing calculator is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are programmable calculators, allowing the user to create customized programs, typically for scientific, engineering or education applications. They have large screens that display several lines of text and calculations.
A scientific calculator is an electronic calculator, either desktop or handheld, designed to perform calculations using basic and complex mathematical operations and functions. They have completely replaced slide rules and are used in both educational and professional settings.
Pocket Viewer was a model range of personal digital assistants (PDAs) developed by Casio around the turn of the 21st Century.
The Casio FX-850P is a scientific calculator introduced in 1987 and sold until 1999.
The Tandy Pocket Computer or TRS-80 Pocket Computer is one of a line of 1980s small pocket computers—calculator-sized programmable computing devices—sold by Tandy Corporation under the "Tandy" or "RadioShack TRS-80" brands.
The TRS-80 Model 100 is a portable computer introduced in April 1983. It is one of the first notebook-style computers, featuring a keyboard and liquid-crystal display, in a battery-powered package roughly the size and shape of a notepad or large book. The 224-page, spiral-bound User Manual is nearly the same size as the computer itself.
There are various ways in which calculators interpret keystrokes. These can be categorized into two main types:
An electronic dictionary is a dictionary whose data exists in digital form and can be accessed through a number of different media. Electronic dictionaries can be found in several forms, including software installed on tablet or desktop computers, mobile apps, web applications, and as a built-in function of E-readers. They may be free or require payment.
Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than general-purpose use.
A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric display device of limited resolution.
The HP-16C Computer Scientist is a programmable pocket calculator that was produced by Hewlett-Packard between 1982 and 1989. It was specifically designed for use by computer programmers, to assist in debugging. It is a member of the HP Voyager series of programmable calculators. It was the only programmer's calculator ever produced by HP, though many later HP calculators have incorporated most of the 16C's functions.
Casio BASIC is a programming language used in the Casio calculators such as the Classpad, PRIZM Series, fx-9860G Series, fx-5800P, Algebra FX and CFX graphing calculators. It is also known as "BasicLike" in some models.
The Casio PB-1000 is a handheld computer released by Casio in 1987. It featured a touchscreen display which consisted of 16 keys built into the screen, arranged in fixed positions on a four by four matrix.
The Casio fx-9860G is a series of graphing calculators manufactured by Casio, successor of the fx-9750G PLUS/CFX-9850 PLUS/CFX-9950 PLUS/CFX-9970 family of calculators. All of them are capable of being programmed by means of sophisticated languages and tools including assembly language, Basic variants, and ports of programming languages such as C, as well as hosting add-ins which are compiled on a computer and then downloaded to the calculator.
OWBasic is an interpreted language environment that can be downloaded to Personal digital assistants like the Casio's Pocket viewer.
Extended Color Basic is an update to the Color BASIC interpreter for the Radio Shack/Tandy TRS-80 Color Computer series and is the default Basic interpreter, for the Color Computer 2. The Color Computer Basic implementations are somewhat different for the versions of Basic which come with the other family of TRS-80 machines, namely Basic Levels I, II, and III. Assemblers and Pascal and C programming language compilers are available for the different machines in the series. Modified subsets of Color Basic may be found on many of the Radio Shack PC series of pocket computers of the era.
Disk Extended Color Basic is an update to the Color BASIC interpreter for the Radio Shack/Tandy TRS-80 Color Computer series and is the default BASIC interpreter, and therefore the de facto operating system, for the Color Computer 3. The Color Computer Basic implementations are somewhat different for the versions of Basic which come with the other family of TRS-80 machines, namely Basic Levels I, II, and III. Assemblers and Pascal and C compilers are available for the different machines in the series. Modified subsets of Color Basic may be found on many of the Radio Shack PC series of pocket computers of the era.
The Casio Algebra FX series was a line of graphing calculators manufactured by Casio Computer Co., Ltd from 1999 to 2003. They were the successor models to the CFX-9970G, the first Casio calculator with computer algebra system, or CAS, a program for symbolic manipulation of mathematical expressions. The calculators were discontinued and succeeded by the Casio ClassPad 300 in 2003.
