Contents.History NSB Corporation was founded by George Henne in 1993 to provide easy development tools for mobile devices; the manufacturers and licensors of the operating systems usually supply a -based tool aimed at highly skilled professional developers. NSB/AppStudio provides an alternative using the JavaScript or Basic programming language, similar to. Key developers include George Henne, Marcus Darden, James Kruth, Eric Pepke and Dan Rowley.As of 2019, NS Basic's tools are used by over three million developers in over 80 countries.Until 2019, NSB Corporation was known as NS BASIC Corporation.NSB/AppStudio AppStudio was released in December, 2010, it consists of an, a programming language and a deploy module.
The IDE and programming language are modeled on 's. Two languages are supported for development: JavaScript and BASIC. Virtually the entire syntax is implemented; the runtime environment is based on, and: many of the features of the underlying technologies is exposed to the AppStudio environment. Programming can be done in Basic or JavaScript., and are fully integrated; the programs produced by AppStudio are.Apps install themselves as offline web applications, they can run on Apple's devices (, ) and devices running 2.1 or later.AppStudio can also be used to create apps which run on, and; the use of modules is supported.The latest version of AppStudio is 7.3.0, released in February 2019.Example code.
An operating system is system software that manages computer hardware and software resources and provides common services for computer programs. Operating systems schedule tasks for efficient use of the system and may include accounting software for cost allocation of processor time, mass storage and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is executed directly by the hardware and makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers; the dominant desktop operating system is with a market share of around 82.74%. By Apple Inc. Is in second place, the varieties of are collectively in third place. In the mobile sector, use in 2017 is up to 70% of Google's and according to third quarter 2016 data, Android on is dominant with 87.5 percent and a growth rate 10.3 percent per year, followed by Apple's iOS with 12.1 percent and a per year decrease in market share of 5.2 percent, while other operating systems amount to just 0.3 percent.Linux distributions are dominant in supercomputing sectors.
Other specialized classes of operating systems, such as embedded and real-time systems, exist for many applications. A single-tasking system can only run one program at a time, while a operating system allows more than one program to be running in concurrency; this is achieved by time-sharing, where the available processor time is divided between multiple processes. These processes are each interrupted in time slices by a task-scheduling subsystem of the operating system. Multi-tasking may be characterized in co-operative types.
In, the operating system slices the CPU time and dedicates a slot to each of the programs. Operating systems, such as and Linux—as well as non-Unix-like, such as AmigaOS—support preemptive multitasking. Cooperative multitasking is achieved by relying on each process to provide time to the other processes in a defined manner. Versions of Microsoft Windows used cooperative multi-tasking.versions of both and Win9x, used preemptive multi-tasking. Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem.
A operating system extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, the system permits multiple users to interact with the system at the same time. Time-sharing operating systems schedule tasks for efficient use of the system and may include accounting software for cost allocation of processor time, mass storage and other resources to multiple users. A distributed operating system manages a group of distinct computers and makes them appear to be a single computer; the development of networked computers that could be linked and communicate with each other gave rise to distributed computing. Distributed computations are carried out on more than one machine; when computers in a group work in cooperation, they form a distributed system.In an OS, distributed and cloud computing context, templating refers to creating a single as a guest operating system saving it as a tool for multiple running virtual machines.
The technique is used both in and cloud computing management, is common in large server warehouses. Embedded operating systems are designed to be used in embedded computer systems, they are designed to operate on small machines like with less autonomy. They are able to operate with a limited number of resources, they are compact and efficient by design. And 3 are some examples of embedded operating systems. A is an operating system that guarantees to process events or data by a specific moment in time.
A real-time operating system may be single- or multi-tasking, but when multitasking, it uses specialized scheduling algorithms so that a nature of behavior is achieved. An system switches between tasks based on their priorities or external events while operating systems switch tasks based on clock interrupts.A library operating system is one in which the services that a typical operating system provides, such as networking, are provided in the form of libraries and composed with the application and configuration code to construct a: a specialized, single address space, machine image that can be deployed to cloud or embedded environments. Early computers were built to perform a series of single tasks, like a calculator. Basic operating system features were developed in the 1950s, such as resident monitor functions that could automatically run different programs in succession to speed up processing.
Operating systems did not exist in their more complex forms until the early 1960s. Hardware features were added, that enabled use of runtime libraries and parallel processing; when personal computers became popular in the 1980s, operating systems were made for them similar in concept to those used on larger computers. In the 1940s, the earliest electronic digital systems had no operating systems.Electronic systems of this time were programmed on rows of mechanical switches or by jumper wires on plug boards.
These were special-purpose systems that, for example, generated tables for the military or controlled the pri. Is a line of designed and marketed by Apple Inc. All generations of the iPhone use Apple's iOS software; the first-generation iPhone was released on June 29, 2007, multiple new hardware iterations with new iOS releases have been released since. The user interface is built around the device's screen, including a virtual; the iPhone can connect to cellular networks. An iPhone can shoot video, take photos, play music and receive email, browse the web and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, receive visual. Other functionality, such as video games, reference works, social networking, can be enabled by downloading mobile apps; as of January 2017, contained more than 2.2 million applications available for the iPhone. Apple has released twelve generations of iPhone models, each accompanied by one of the twelve major releases of the iOS operating system.The original first-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations.
The iPhone 3G added 3G network support, was followed by the 3GS with improved hardware, the 4 with a metal chassis, higher display resolution and front-facing camera, the 4S with improved hardware and the voice assistant; the iPhone 5 featured Apple's newly introduced Lightning connector. In 2013, Apple released the 5S with improved hardware and a reader, the lower-cost 5C, a version of the 5 with colored plastic casings instead of metal, they were followed by the larger iPhone 6, with models featuring 4.7-and-5.5-inch displays. The iPhone 6S was introduced the following year, which featured hardware upgrades and support for pressure-sensitive touch inputs, as well as the SE—which featured hardware from the 6S but the smaller form factor of the 5S. In 2016, Apple unveiled the, which add water resistance, improved system and graphics performance, a new rear dual-camera setup on the Plus model, new color options, while removing the found on previous models.The were released in 2017, adding a glass back and an improved screen and camera.
The iPhone X was released alongside the 8 and 8 Plus, with its highlights being a near bezel-less design, an improved camera and a new facial recognition system, named, but having no home button, therefore, no. In September 2018, Apple again released 3 new iPhones, which are the iPhone XS, an upgraded version of the since discontinued iPhone X, iPhone XS Max, a larger variant with the series' biggest display as of 2018 and iPhone XR, a lower end version of the iPhone X; the original iPhone was described as 'revolutionary' and a 'game-changer' for the mobile phone industry. Subsequent iterations of the iPhone have garnered praise; the iPhone is one of the most used smartphones in the world, its success has been credited with helping Apple become one of the world's most valuable publicly traded companies. Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1,000 employees to work on the confidential 'Project Purple.'
Apple CEO steered the original focus away from a tablet towards a phone. Apple created the device during a secretive collaboration with at the time—at an estimated development cost of US$150 million over thirty months. According to Steve Jobs, the 'i' word in ' stands for internet, instruct and inspire. Apple rejected the 'design by committee' approach that had yielded the, a unsuccessful collaboration with. Among other deficiencies, the ROKR E1's limited storage to only 100 songs to avoid competing with Apple's nano.
Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house and paid Apple a fraction of its monthly service revenue, in exchange for four years of exclusive US sales, until 2011. Jobs unveiled the to the public on January 9, 2007, at the 2007 convention at the in; the two initial models, a 4 GB model priced at US$499 and an 8 GB model at US$599, went on sale in the on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide.The passionate reaction to the launch of the iPhone resulted in sections of the media dubbing it the'Jesus phone'. Following this successful release in the US, the first generation iPhone was made available in the UK, in November 2007, and in the spring of 2008.
On July 11, 2008, Apple released the iPhone 3G including the original six. Apple released the iPhone 3G in upwards of eighty territories.
Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it in June and August, starting with the US, and major European countries on June 19. Many would-be users objected to the iPhone's cost, 40% of users had household incomes over US$100,000; the back of the original first generation iPhone was made of with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal; the iPhone 3G was available in.

Following Palm's purchase of the Palm trademark, the licensed version from ACCESS was renamed OS. In 2007, ACCESS introduced the successor to Garnet OS, called and in 2009, the main licensee of Palm OS, Inc. Switched from Palm OS to for their forthcoming devices. Palm OS was developed under the direction of at, Inc. Palm was acquired by U. Which in turn was bought by, which made the Palm an independent publicly traded company on March 2, 2000. In January 2002, Palm set up a wholly owned subsidiary to develop and license Palm OS, named.PalmSource was spun off from Palm as an independent company on October 28, 2003.
Palm became a regular licensee of Palm OS, no longer in control of the operating system. In September 2005, PalmSource announced that it was being acquired by ACCESS.
In December 2006, Palm gained perpetual rights to the Palm OS source code from ACCESS. With this Palm can modify the licensed operating system as needed without paying further to ACCESS. Together with the May 2005 acquisition of full rights to the Palm brand name, only Palm can publish releases of the operating system under the name'Palm OS'; as a consequence, on January 25, 2007, ACCESS announced a name change to their current Palm OS operating system, now titled Garnet OS. Palm OS is a mobile operating system. Designed in 1996 for Palm Computing, Inc.' S new Pilot PDA, it has been implemented on a wide array of mobile devices, including smartphones, wrist watches, handheld gaming consoles, readers and GPS devices. Palm OS versions earlier than 5.0 run on Motorola/Freescale DragonBall processors.From version 5.0 onwards, Palm OS runs on ARM architecture-based processors.
Is a discontinued interpreter for the BASIC programming language that ran on the and subsequent bus computers. It was Microsoft's first product, distributed by under a contract. Altair BASIC was the start of the product range. Recalls that, when he and read about the in the January 1975 issue of, they understood that the price of computers would soon drop to the point that selling software for them would be a profitable business.
Gates believed that, by providing a BASIC interpreter for the new computer, they could make it more attractive to hobbyists, they contacted MITS founder, told him that they were developing an interpreter, asked whether he would like to see a demonstration. This followed the questionable engineering industry practice of a trial balloon, an announcement of a non-existent product to gauge interest. Roberts agreed to meet them for a demonstration in a few weeks, in March 1975.Gates and Allen had neither an interpreter nor an Altair system on which to develop and test one. However, Allen had written an for their previous venture that ran on a computer, he adapted this emulator based on the Altair programmer guide, they developed and tested the interpreter on Harvard's PDP-10. Harvard officials were not pleased when they found out, but there was no written policy that covered the use of this computer. Gates and Allen bought computer time from a timesharing service in to complete their BASIC program, they hired Harvard student to write arithmetic routines for the interpreter, a feature not available in many of its competitors. The finished interpreter, including its own I/O system and line editor, fit in only four of memory, leaving plenty of room for the interpreted program.
In preparation for the demo, they stored the finished interpreter on a punched tape that the Altair could read, Paul Allen flew to.On final approach, Allen realized that they had forgotten to write a program to read the tape into memory. Writing in machine language, Allen finished the program. Only when they loaded the program onto an Altair and saw a prompt asking for the system's memory size did Gates and Allen know that their interpreter worked on the Altair hardware, they made a bet on who could write the shortest bootstrap program, Gates won. Roberts agreed to distribute the interpreter, he hired Gates and Allen to maintain and improve it, causing Gates to take a leave of absence from Harvard. They produced several versions: the original 4K BASIC and 8K BASIC, Extended BASIC, Extended, Disk BASIC; the smallest version, 4K BASIC, was able to run within a 4k RAM machine, leaving only about 790 bytes free for program code. To make the language fit in such a small space, the 4K version lacked string handling and stripped out a number of the mathematical functions; these were added back into the 8K BASIC, which had the string library, a larger set of math functions including RND for random numbers, boolean operators,.The 8K version is the basis for most versions of BASIC during the home computer era.
Extended BASIC added PRINT USING and basic disk commands, while Disk BASIC further extended the disk commands to allow raw I/O. In October 1975, 4K BASIC sold for $150, 8K BASIC for $200, Extended BASIC for $350; the prices were discounted to $60, $75, $150 for those who purchased '8K of Altair memory, an Altair I/O board.' The language versions were available on tape. As they expected, the Altair was popular with hobbyists such as the., as ' preferred BASIC interpreter, was popular. However, the hobbyists took a ' approach to software and thought nothing of copying the BASIC interpreter for other hobbyists. Member Dan Sokol was prolific. Gates responded in 1976 with a worded that accused the copiers of theft and declared that he could not continue developing computer software that people did not pay for.
Many hobbyists reacted defensively to the letter.Under the terms of the purchase agreement, MITS would receive the rights to the interpreter after it had paid a certain amount in. However, had developed versions of the interpreter for other systems such as the 6800; when they decided to leave MITS, a dispute arose over whether the full amount had been paid and whether the agreement applied to the other versions.
Microsoft and MITS took the dispute to an arbitrator who, much to Roberts' surprise, decided in favor of Microsoft based on MITS failure to market the software with their 'best efforts'.

Its origin dated back to in 1996, though Windows Mobile itself first appeared in 2000 as PocketPC 2000, it was renamed 'Windows Mobile' in 2003, at which point it came in several versions and was aimed at business and enterprise consumers. It became one of the most popular mobile operating systems as of the mid-2000s, but its popularity faded in the following years, by February 2010, facing competition from rival mobile OSs, including Apple's iOS and, Microsoft announced to supersede Windows Mobile; as a result, Windows Mobile has been deprecated. Windows Phone is incompatible with software; the last version of Windows Mobile, released after the announcement of Windows Phone, was 6.5.5. After this, Microsoft ceased development on Windows Mobile, in order to concentrate on Windows Phone. Most versions of Windows Mobile have a standard set of features, such as and the ability to navigate a file system similar to that of Windows 9x and, including support for many of the same file types.To its desktop counterpart, it comes bundled with a set of applications that perform basic tasks.
Is the default web browser, is the default media player used for playing digital media; the mobile version of, is the default office suite., supported on compatible devices, allows the phone to share its Internet connection with computers via USB. Windows Mobile supports virtual private networking over protocol. Most devices with mobile connectivity have a; the Radio Interface Layer provides the system interface between the Cell Core layer within the Windows Mobile OS and the radio protocol stack used by the wireless hardware. This allows to integrate a variety of modems into their equipment; the user interface changed between versions, only retaining similar functionality. The Today Screen called the Home Screen, shows the current date, owner information, upcoming appointments, e-mails, tasks.The display the current time as well as the volume level.
Devices with a cellular radio show the signal strength on said taskbar. Windows Mobile is based on the Windows CE kernel and first appeared as the 2000 operating system, it includes a suite of basic applications developed with the API, is designed to have features and appearance somewhat similar to desktop versions of Windows.
It allowed third party developers to develop software for Windows Mobile with no restrictions imposed by Microsoft. Software applications were purchasable from during the service's lifespan. Most early Windows Mobile devices came with a, which can be used to enter commands by tapping it on the screen; the primary touch input technology behind most devices were resistive touchscreens which required a stylus for input. Devices used sensing which does not require a stylus.
Along with touchscreens, a large variety of form factors existed for the platform.Some devices featured slideout. Microsoft's work on handheld portable devices began with research projects in 1990, with the work on Windows CE beginning in 1992; the OS and the user interface were developed separately. With Windows CE being based on Windows 95 code and a separate team handing the user interface, codenamed WinPad.
Windows 95 had strong pen support making porting easy, it is treating pens right for the first time.' WinPad was delayed due to price and performance issues, before being scrapped in early 1995 due to driver problems relating to WriteTouch technology, made by NCR Products. Although WinPad was never released as a consumer product, Alpha builds were released showcasing many interface elements. During development of WinPad a separate team worked on a project called; this project was canceled around the same time as WinPad. The two disbanded groups would form the project in 1995. Pegasus would work on the hardware side of the OS, attempting to create a form factor similar to a PC-esque PDA like WinPad, with communications functionality like Pulsar.A hardware reference guide was created and devices began shipping in 1996, although most of these device bore little resemblance to the goal of a pen-based touchscreen handheld device. Pocket PC 2000 codenamed ', was released on April 19, 2000, was based on the Windows CE 3.0 kernel.
It was the debut of what was dubbed the Windows, meant to be a successor to the operating system aboard Palm-Size PCs, it retained backwards compatibility with such applications. Pocket PC 2000 was intended for Pocket PC devices.
While, several Pocket PC 2000 phones were released, Microsoft's hardware platform was not yet created; the only resolution supported by this release was 240×320. Removable storage card formats that were supported were.
At this time Pocket PC devices had not been standardized with a specific CPU architecture; as a result, Pocket PC 2000 was released on multiple CPU architectures. File beaming capability was amo. BASIC is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use.
In 1964, and designed the original BASIC language at, they wanted to enable students in fields other than to use computers. At the time, nearly all use of computers required writing custom software, something only scientists and mathematicians tended to learn. In addition to the language itself and Kurtz developed the, which allowed multiple users to edit and run BASIC programs at the same time; this general model became popular on systems like the and in the late 1960s and early 1970s.
Produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales into the 1980s. Many early video games trace their history to one of these versions of BASIC; the emergence of early microcomputers in the mid-1970s led to the development of the original in 1975.Due to the tiny main memory available on these machines 4 kB, a variety of dialects were created. BASIC was available for any system of the era, became the de facto programming language for the home computer systems that emerged in the late 1970s; these machines always had a BASIC installed by default in the machine's or sometimes on a ROM cartridge. BASIC fell from use during the 1980s as newer machines with far greater capabilities came to market and other programming languages became tenable.
In 1991, released, combining a updated version of BASIC with a visual forms builder; this reignited use of the language and 'VB' remains a major programming language in the form of VB. Kemeny was the math department chairman at Dartmouth College, on his reputation as an innovator in math teaching, in 1959 the school won an award for $500,000 to build a new department building. Kurtz had joined the department in 1956, from the 1960s they agreed on the need for programming literacy among students outside the traditional STEM fields.Kemeny noted that “Our vision was that every student on campus should have access to a computer, any faculty member should be able to use a computer in the classroom whenever appropriate. It was as simple as that.' Kemeny and Kurtz had made two previous experiments with simplified languages, DARSIMCO and DOPE. These did not progress past a single freshman class. New experiments using and followed, but Kurtz concluded these languages were too for what they desired; as Kurtz noted, Fortran had numerous oddly-formed commands, notably an 'almost impossible-to-memorize convention for specifying a loop:'DO 100, I = 1, 10, 2'.
Is it'1, 10, 2' or'1, 2, 10', is the comma after the line number required or not?' Moreover, the lack of any sort of immediate feedback was a key problem. Kurtz suggested. Small programs would return results in a few seconds; this led to increasing interest in a system using and a new language for use by non-STEM students. Kemeny wrote the first version of BASIC.The BASIC comes from the name of an unpublished paper by Thomas Kurtz. The new language was patterned on FORTRAN II. However, the was changed.
For instance, the difficult to remember DO loop was replaced by the much easier to remember FOR I = 1 TO 10 STEP 2, the line number used in the DO was instead indicated by the NEXT I; the cryptic IF statement of Fortran, whose syntax matched a particular instruction of the machine on which it was written, became the simpler IF I=5 THEN GOTO 100. These changes made the language much less idiosyncratic while still having an overall structure and feel similar to the original FORTRAN; the project received a $300,000 grant from the, used to purchase a GE-225 computer for processing, a realtime processor to handle the teleprinters used for input and output.
A team of a dozen undergraduates worked on the project for about a year, writing both the DTSS system and the BASIC; the main CPU was replaced by a GE-235, still by a GE-635 The first version BASIC language was released on 1 May 1964.One of the graduate students on the implementation team was Sr., one of the first people in the to earn a Ph. In computer science and the first woman to do so.
BASIC concentrated on supporting straightforward mathematical work, with matrix arithmetic support from its initial implementation as a batch language, character string functionality being added by 1965. Wanting use of the language to become widespread, its designers made the compiler available free of charge, they made it available to high schools in the area and put considerable effort into.
Is a third-generation programming language from for its programming model first released in 1991 and declared legacy during 2008. Microsoft intended Visual Basic to be easy to learn and use. Visual Basic was derived from BASIC and enables the of graphical user interface applications, access to databases using, or, creation of controls and objects. A programmer can create an application using the components provided by the Visual Basic program itself. Over time the community of programmers developed third-party components. Programs written in Visual Basic can use the, which requires external function declarations; the final release was version 6 in 1998.
On April 8, 2008, Microsoft stopped supporting Visual Basic 6.0 IDE. The team still maintains compatibility for Visual Basic 6.0 applications on, Windows Server 2008 including R2, Windows 7, Windows 8, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2016, through its 'It Just Works' program.In 2014, some software developers still preferred Visual Basic 6.0 over Visual Basic. In 2014 some developers lobbied for a new version of the VB6 programming environment. In 2016, Visual Basic 6.0 won the technical impact award at The 19th Annual D. A dialect of Visual Basic, is used as a macro or scripting language within several Microsoft applications, including. Like the BASIC programming language, Visual Basic was designed for an easy learning curve. Programmers can create both complex GUI applications.
Programming in VB is a combination of visually arranging components or controls on a form, specifying attributes and actions for those components, writing additional lines of code for more functionality. Since VB defines default attributes and actions for the components, a programmer can develop a simple program without writing much code. Programs built with earlier versions suffered performance problems, but faster computers and native code compilation has made this less of an issue.Though VB programs can be compiled into native code executables from version 5 on, they still require the presence of around 1 MB of runtime libraries. Core runtime libraries are included by default in Windows 2000 and but extended runtime components still have to be installed.
Earlier versions of Windows, require. Forms are created using techniques.
A tool is used to place controls on the form. Controls have attributes and event handlers associated with them. Default values may be changed by the programmer. Many attribute values can be modified during run time based on user actions or changes in the environment, providing a dynamic application. For example, code can be inserted into the form resize event handler to reposition a control so that it remains centered on the form, expands to fill up the form, etc.
By inserting code into the event handler for a keypress in a text box, the program can automatically translate the case of the text being entered, or prevent certain characters from being inserted.Visual Basic can create executables, ActiveX controls, or DLL files, but is used to develop Windows applications and to interface database systems. Dialog boxes with less functionality can be used to provide pop-up capabilities. Controls provide the basic functionality of the application, while programmers can insert additional logic within the appropriate event handlers. For example, a drop-down combination box automatically displays a list; when the user selects an element, an event handler is called that executes code that the programmer created to perform the action for that list item. Alternatively, a component can have no user interface, instead provide ActiveX objects to other programs via; this allows for an add-in module.
The runtime recovers unused memory using reference counting, which depends on variables passing out of scope or being set to Nothing, avoiding the problem of memory leaks that are possible in other languages. There is a large library of utility objects, the language provides basic support for programming.Unlike many other programming languages, Visual Basic is not case-sensitive—though it transforms keywords into a standard case configuration and forces the case of variable names to conform to the case of the entry in the symbol table. String comparisons are case sensitive by default; the Visual Basic is shared with other languages. By default the restrictions in the IDE do not allow creation of some targets and threading models, but over the years, developers have bypassed these restrictions. Visual Basic builds upon the characteristics of BASIC. There are no line numbers as in earlier BASIC, code is grouped into or methods: Sub. Code Statements have no terminating character other than a line ending.
Versions since at least VB 3.0 allowed that statements can be implicitly multi-line with of strings or explicitly using the underscore character at the end of lines. Code comments are done with a single character.' This is a comment Looping statement blocks begin and end with keywords: Do.Loop, While. End While, For.
Multiple variable assignment is not.
