Ulead Systems is a Taiwanese computer software company headquartered in Neihu district in Taipei, Taiwan. It is a subsidiary of Corel. Ulead was founded on 5 August 1989 by Lewis Liaw and Way-Zen Chen, they founded Ulead with the support of Microtek after leaving Taiwan's Institute for Information Industry in order to further develop and commercialize their first true color image editing software, PhotoStyler, on the Windows platform. Ulead sold PhotoStyler through Aldus software as a software developer. However, Aldus merged into Adobe Systems in 1994 and PhotoStyler is no longer available. Ulead continued to develop PhotoImpact 3 as its flagship image editor and sell PhotoImpact by itself. Today, PhotoImpact is known as a competitor of Adobe Photoshop. Ulead Systems extended its development of multimedia software in various areas such as video editing, media management, web utility, DVD authoring and digital home. On 17 September 2001, Ulead was listed on the Taiwan Stock Exchange as 2487. TW.

Raster graphics editor
A raster graphics editor is a computer program that allows users to create and edit images interactively on the computer screen and save them in one of many "bitmap" or "raster" formats such as JPEG, PNG, GIF. Vector graphics editors are contrasted with raster graphics editors, yet their capabilities complement each other; the technical difference between vector and raster editors stem from the difference between vector and raster images. Vector graphics are created mathematically; each element is manipulated numerically. Raster images include digital photos. A raster image is made up of rows and columns of dots, called pixels, is more photo-realistic; this is the standard form for digital cameras. The image is represented pixel like a microscopic jigsaw puzzle. Vector editors tend to be better suited for graphic design, page layout, logos, sharp-edged artistic illustrations, e.g. cartoons, clip art, complex geometric patterns, technical illustrations and flowcharting. Advanced raster editors, like GIMP and Adobe Photoshop, use vector methods for general layout and elements such as text, but are equipped to deal with raster images down to the pixel and have special capabilities in doing so, such as brightness/contrast, adding "lighting" to a raster image or photograph.

Microsoft Windows is a group of several graphical operating system families, all of which are developed and sold by Microsoft. Each family caters to a certain sector of the computing industry. Active Windows families include Windows Embedded. Defunct Windows families include Windows Mobile and Windows Phone. Microsoft introduced an operating environment named Windows on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces. Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, introduced in 1984. Apple came to see Windows as an unfair encroachment on their innovation in GUI development as implemented on products such as the Lisa and Macintosh. On PCs, Windows is still the most popular operating system. However, in 2014, Microsoft admitted losing the majority of the overall operating system market to Android, because of the massive growth in sales of Android smartphones.
In 2014, the number of Windows devices sold was less than 25 %. This comparison however may not be relevant, as the two operating systems traditionally target different platforms. Still, numbers for server use of Windows show one third market share, similar to that for end user use; as of October 2018, the most recent version of Windows for PCs, tablets and embedded devices is Windows 10. The most recent versions for server computers is Windows Server 2019. A specialized version of Windows runs on the Xbox One video game console. Microsoft, the developer of Windows, has registered several trademarks, each of which denote a family of Windows operating systems that target a specific sector of the computing industry; as of 2014, the following Windows families are being developed: Windows NT: Started as a family of operating systems with Windows NT 3.1, an operating system for server computers and workstations. It now consists of three operating system subfamilies that are released at the same time and share the same kernel: Windows: The operating system for mainstream personal computers and smartphones.
The latest version is Windows 10. The main competitor of this family is macOS by Apple for personal computers and Android for mobile devices. Windows Server: The operating system for server computers; the latest version is Windows Server 2019. Unlike its client sibling, it has adopted a strong naming scheme; the main competitor of this family is Linux. Windows PE: A lightweight version of its Windows sibling, meant to operate as a live operating system, used for installing Windows on bare-metal computers, recovery or troubleshooting purposes; the latest version is Windows PE 10. Windows IoT: Initially, Microsoft developed Windows CE as a general-purpose operating system for every device, too resource-limited to be called a full-fledged computer. However, Windows CE was renamed Windows Embedded Compact and was folded under Windows Compact trademark which consists of Windows Embedded Industry, Windows Embedded Professional, Windows Embedded Standard, Windows Embedded Handheld and Windows Embedded Automotive.
The following Windows families are no longer being developed: Windows 9x: An operating system that targeted consumers market. Discontinued because of suboptimal performance. Microsoft now caters to the consumer market with Windows NT. Windows Mobile: The predecessor to Windows Phone, it was a mobile phone operating system; the first version was called Pocket PC 2000. The last version is Windows Mobile 6.5. Windows Phone: An operating system sold only to manufacturers of smartphones; the first version was Windows Phone 7, followed by Windows Phone 8, the last version Windows Phone 8.1. It was succeeded by Windows 10 Mobile; the term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are categorized as follows: The history of Windows dates back to 1981, when Microsoft started work on a program called "Interface Manager", it was announced in November 1983 under the name "Windows", but Windows 1.0 was not released until November 1985.
Windows 1.0 was to achieved little popularity. Windows 1.0 is not a complete operating system. The shell of Windows 1.0 is a program known as the MS-DOS Executive. Components included Calculator, Cardfile, Clipboard viewer, Control Panel, Paint, Reversi and Write. Windows 1.0 does not allow overlapping windows. Instead all windows are tiled. Only modal dialog boxes may appear over other windows. Microsoft sold as included Windows Development libraries with the C development environment, which included numerous windows samples. Windows 2.0 was released in December 1987, was more popular than its predecessor. It features several improvements to the user memory management. Windows 2.03 changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights. Windows 2.0
An operating system is system software that manages computer hardware and software resources and provides common services for computer programs. 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. 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 Microsoft Windows with a market share of around 82.74%. MacOS by Apple Inc. is in second place, the varieties of Linux are collectively in third place. In the mobile sector, use in 2017 is up to 70% of Google's Android and according to third quarter 2016 data, Android on smartphones 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 multi-tasking 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 preemptive multitasking, the operating system slices the CPU time and dedicates a slot to each of the programs. Unix-like operating systems, such as Solaris 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. 16-bit versions of Microsoft Windows used cooperative multi-tasking.
32-bit versions of both Windows NT 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 multi-user 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 virtual machine image as a guest operating system saving it as a tool for multiple running virtual machines. The technique is used both in virtualization 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 PDAs with less autonomy. They are able to operate with a limited number of resources, they are compact and efficient by design. Windows CE and Minix 3 are some examples of embedded operating systems. A real-time operating system 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 deterministic nature of behavior is achieved. An event-driven system switches between tasks based on their priorities or external events while time-sharing 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 unikernel: 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 ballistics tables for the military or controlled the pri
Corel Corporation is a Canadian software company headquartered in Ottawa, specializing in graphics processing. It is known for producing software titles such as CorelDRAW, for acquiring PaintShop Pro, Video Studio and WordPerfect. Corel was founded by Michael Cowpland in 1985 as a research laboratory; the company had great success early in the high-tech boom of the 1990s and early 2000s with the product CorelDRAW, became, for a time, the biggest software company in Canada. In 1996 it acquired Novell WordPerfect and started competing with the thought of being "Pepsi to Microsoft's Coke" as Microsoft Word was the top-used word processing software at the time. Corel was in a difficult position as Microsoft pushed pre-loaded copies of its software onto new computers; this consisted of Microsoft Works office applications, but a variant called Works Suite bundled the Microsoft Word software. The company held the naming rights to the home arena for the NHL's Ottawa Senators from February 1996 until January 2006 as the "Corel Centre", a venue known as the Canadian Tire Centre.
In 1997 Corel sold its Corel ChemLab studio and its "CD Home Collection" consisting of over 60 multimedia titles to Hoffmann + Associates, a Toronto-based company. As part of the deal, Corel acquired a minority interest in Hoffmann + Associates and received royalties. In August 2000 Cowpland was left. A new board of directors was appointed and Derek Burney Jr. announced that the product line would be split into several brands—DeepWhite, ProCreate, Corel. However, these plans would be scrapped, only the Corel brand would remain. Corel acquired the graphics software company Micrografx in late 2001. In August 2003, Corel was bought out by the private equity firm Vector Capital for $1.05 a share. The company was voluntarily delisted from the Toronto Stock Exchanges; some U. S. shareholders alleged the management benefited from the buyout while the buyout price was too low. A lawsuit was filed in the U. S. to was unsuccessful. In March 2005 Corel announced that the United States Justice Department purchased 50,000 licenses of WordPerfect and that WordPerfect was adding 4 million new users per year thanks to bundling deals with Dell.
Corel contended that WordPerfect was the only viable alternative to Microsoft Office, with sales 70 times more than Lotus' SmartSuite. On April 26, 2006, Corel completed its return to the public market with an initial public offering on NASDAQ, the same day finalizing the acquisition of WinZip, a well-known archiving software title. On December 12, 2006, Corel completed its acquisitions of Ulead; the InterVideo acquisition was valued at around $196 million. In May 2008, CEO David Dobson announced that he was leaving the company to take a senior strategy role at Pitney Bowes. Dobson was replaced on May 8 by former Symantec executive Kris Hagerman. In November 2009, it was announced that Vector Capital would be purchasing the remaining shares of common stock in Corel Corporation. Upon completion, this made Corel once again owned. On January 29, 2010, the shareholders of Corel approved its announced stock consolidation, completing the transfer to Corel Holdings, L. P. a limited partnership controlled by an affiliate of Vector Capital.
In January 2012, Corel acquired Roxio from Rovi Corporation for an undisclosed amount. Subsequently on July 2, 2012, Corel announced its acquisition of Pinnacle Systems, a developer of consumer-oriented video editing products owned by Avid. Having suffered layoffs in 2003 and 2008, Corel began a near yearly culture of restructuring beginning in 2010, when in the latter part of that year the company's finance department was restructured and moved to their Taipei office, resulting in significant layoffs at its Ottawa HQ. Restructuring in 2012 resulted in more layoffs. In December 2013, the company's restructuring resulted in the layoffs of the Taipei locations engineering and quality assurance team. Corel's Taipei office was the core development centre of PaintShop Pro and VideoStudio, one of the company's most well-known photo- and video-editing bundles; the 2013 restructuring led to a partial handover of product development to outsourced companies, resulting in more rapid, low-cost development across its product lines.
The company continued with layoffs in 2014 and once again at the beginning of 2015 with the change of the company's CEO to Patrick Nichols the head of Corel's WinZip business unit. In August 2016, Corel announced the acquisition of the Mindjet MindManager business from Spigit. In June 2018, Corel announced the acquisition of Gravit GmbH. In December 2018, Corel announced the acquisition of Parallels.
