The keyboard for IBM PC-compatible computers is standardized. However, during the more than 30 years of PC architecture being frequently updated, many keyboard layout variations have been developed.
A personal digital assistant (PDA), also known as a handheld PC, is a variety mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android.
A function key is a key on a computer or terminal keyboard which can be programmed so as to cause an operating system command interpreter or application program to perform certain actions, a form of soft key. On some keyboards/computers, function keys may have default actions, accessible on power-on.
The HP-35 was Hewlett-Packard's first pocket calculator and the world's first scientific pocket calculator: a calculator with trigonometric and exponential functions. It was introduced in 1972.
Microsoft has designed and sold a variety of ergonomic keyboards for computers. The oldest is the Microsoft Natural Keyboard, released in 1994, the company's first computer keyboard. The newest models are the Sculpt ergonomic keyboard (2013) the Surface Ergonomic Keyboard (2016) and the Microsoft Ergonomic Keyboard (2019).
Windows Calculator is a software calculator developed by Microsoft and included in Windows. It has four modes: standard, scientific, programmer, and a graphing mode. The standard mode includes a number pad and buttons for performing arithmetic operations. The scientific mode takes this a step further and adds exponents and trigonometric function, and programmer mode allows the user to perform operations related to computer programming. Recently, a graphing mode was added to the Calculator, allowing users to graph equations on a coordinate plane.
A human interface device or HID is a type of computer device usually used by humans that takes input from humans and gives output to humans.
HP calculators are various calculators manufactured by the Hewlett-Packard company over the years.
The HP 200LX Palmtop PC, also known as project Felix, is a personal digital assistant introduced by Hewlett-Packard in August 1994. It was often called a Palmtop PC, and it was notable that it was, with some minor exceptions, a MS-DOS-compatible computer in a palmtop format, complete with a monochrome graphic display, QWERTY keyboard, serial port, and PCMCIA expansion slot.
Apple Inc. has designed and released dozens of keyboard models since the introduction of the Apple II in 1977. The current models in use are dual-mode keyboards with integrated batteries: Magic Keyboard, and Magic Keyboard with Numeric Keypad. Both share a similar look and feel, based on a very thin aluminum chassis and laptop-style low-profile keys, sitting much closer to the tabletop than traditional keyboard designs.
The Z22 was one of the first of Palm, Inc.'s handhelds to be released under the new "Palm" brand, and the first to be released without the "Zire" moniker. Released on October 12, 2005, it replaced the monochrome Zire 21, and was priced at $99 USD. The Palm Z22 came with Palm OS Garnet 5.4.9 preloaded and is not upgradable. It featured a 200 MHz Samsung S3C2410 ARM processor developed around the 32-bit ARM920T core that implements the ARMv4T architecture. The Z22 ran on a li-ion battery that had a life of about 8 hours depending on usage.
The Apple Wireless Keyboard is a wireless keyboard built for Macintosh computers and compatible with iOS devices. It interacts over Bluetooth wireless technology and unlike its wired version, it has no USB connectors or ports. Both generations have low-power features when not in use. It was discontinued on October 13, 2015, and was succeeded by the new Magic Keyboard.
Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program, much like a computer. The first programmable calculators such as the IBM CPC used punched cards or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory.
Calculator is a basic calculator application made by Apple Inc. and bundled with its macOS, iOS, and watchOS operating systems. It has three modes: basic, scientific, and programmer. The basic mode includes a number pad, buttons for adding, subtracting, multiplying, and dividing, as well as memory keys. Scientific mode supports exponents and trigonometric functions, and programmer mode gives the user access to more options related to computer programming.
The TI-Nspire is a graphing calculator made by Texas Instruments which was released in July 2007. The original TI-Nspire was developed out of the TI PLT SHH1 prototype calculator, the TI-92 series of calculators released in 1995, and the TI-89 series of calculators released in 1998. The TI-Nspire features a non-QWERTY keyboard and a different key-by-key layout compared to its predecessors. The TI-Nspire allows users to swap out the existing removable keypad with a functional copy of the TI-84 Plus series keypad. The TI-Nspire series I/O has a connector for the TI-Nspire Lab Cradle, another that serves as a connector for TI's wireless network adapter, and a Mini-USB connector for transferring data. The TI-Nspire series is available with and without a computer algebra system.
Unicode input is the insertion of a specific Unicode character on a computer by a user; it is a common way to input characters not directly supported by a physical keyboard. Unicode characters can be produced either by selecting them from a display or by typing a certain sequence of keys on a physical keyboard. In addition, a character produced by one of these methods in one web page or document can be copied into another. In contrast to ASCII's 96 element character set, Unicode encodes hundreds of thousands of graphemes (characters) from almost all of the world's written languages and many other signs and symbols besides.
A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for computers since the 1970s, supplemented by the computer mouse since the 1980s.
The HP 30b is a programmable financial calculator from HP which was released on 7 January 2010. The HP 30b is an advanced version of the HP's prior model HP 20b. Featuring a two line alpha numeric display, ability to input data via Reverse Polish Notation, Algebraic and normal Chain algebraic methods, and twelve digit display.
The Macintosh "System 1" is the first version of Apple Macintosh operating system and the beginning of the classic Mac OS series. It was developed for the Motorola 68000 microprocessor. System 1 was released on January 24, 1984, along with the Macintosh 128K, the first in the Macintosh family of personal computers. It received one update, "System 1.1" on December 29, 1984, before being succeeded by System 2.
A numeric keypad, number pad, numpad, or ten key, is the palm-sized, usually-17-key section of a standard computer keyboard, usually on the far right. It provides calculator-style efficiency for entering numbers. The idea of a 10-key number pad cluster was originally introduced by Tadao Kashio, the developer of Casio electronic calculators.
