A book is a medium for recording information in the form of writing or images. Modern books are typically in codex format, composed of many pages that are bound together and protected by a cover; they were preceded by several earlier formats, including the scroll and the tablet. The book publishing process is the series of steps involved in their creation and dissemination.

As a conceptual object, a book refers to a written work of substantial length, which may be distributed either physically or digitally as an ebook. These works can be broadly classified into fiction (containing invented content, often narratives) and non-fiction (containing content intended as factual truth). A physical book may not contain such a work: for example, it may contain only drawings, engravings, photographs, puzzles, or removable content like paper dolls. It may also be left empty for personal use, as in the case of account books, appointment books, autograph books, notebooks, diaries and sketchbooks.

Books are sold at both regular stores and specialized bookstores, as well as online for delivery, and can be borrowed from libraries. The reception of books has led to a number of social consequences, including censorship.

The modern book industry has seen several major changes due to new technologies, including ebooks and audiobooks (recordings of books being read aloud). Awareness of the needs of print-disabled people has led to a rise in formats designed for greater accessibility, such as braille printing and large-print editions. Google Books estimated in 2010 that approximately 130 million total unique books had been published.

A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is fitted inside the lower lid enclosure under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers.

Laptops can run on both AC power and rechargable battery packs and can be folded shut for convenient storage and transportation, making them suitable for mobile use. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for playing games, web browsing, for personal multimedia, and for general home computer use.

The word laptop, modeled after the term desktop (as in desktop computer), refers to the fact that the computer can be practically placed on the user's lap; while the word notebook refers to most laptops sharing a form factor with paper notebooks. As of 2024, in American English, the terms laptop and notebook are used interchangeably; in other dialects of English, one or the other may be preferred. The term notebook originally referred to a type of portable computer that was smaller and lighter than mainstream laptops of the time, but has since come to mean the same thing and no longer refers to any specific size.

Laptops combine many of the input/output components and capabilities of a desktop computer into a single unit, including a display screen (usually 11–17 in or 280–430 mm in diagonal size), small speakers, a keyboard, and a pointing device (namely compact ones such as touchpads or pointing sticks). Most modern laptops include a built-in webcam and microphone, and many also have touchscreens. Hardware specifications may vary significantly between different types, models, and price points.

Design elements, form factors, and construction can also vary significantly between models depending on the intended use. Examples of specialized models of laptops include 2-in-1 laptops, with keyboards that either be detached or pivoted out of view from the display (often marketed having a "laptop mode"); rugged laptops, for use in construction or military applications; and low-production-cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountants, or traveling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes.

Microsoft Corporation is an American multinational corporation and technology company headquartered in Redmond, Washington. Its best-known software products are the Windows line of operating systems, the Microsoft 365 suite of productivity applications, the Azure cloud computing platform, and the Edge web browser. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface lineup of touchscreen personal computers. Microsoft ranked No. 14 in the 2022 Fortune 500 rankings of the largest United States corporations by total revenue; and it was the world's largest software maker by revenue in 2022 according to Forbes Global 2000. It is considered one of the Big Five American information technology companies, alongside Alphabet (parent company of Google), Amazon, Apple, and Meta (parent company of Facebook).

Microsoft was founded in 1975 by Bill Gates and Paul Allen to develop and sell BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Windows. The company's 1986 initial public offering (IPO) and subsequent rise in its share price created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made several corporate acquisitions, the largest being the acquisition of Activision Blizzard for $68.7 billion in October 2023, followed by its acquisition of LinkedIn for $26.2 billion in December 2016, Nuance Communications for $16 billion in March 2022, and Skype Technologies for $8.5 billion in May 2011.

As of 2015, Microsoft is market-dominant in the IBM PC compatible operating system market and the office software suite market, although it has lost the majority of the overall operating system market to Android. The company also produces a wide range of other consumer and enterprise software for desktops, laptops, tabs, gadgets, and servers, including Internet search (with Bing), the digital services market (through MSN), mixed reality (HoloLens), cloud computing (Azure), and software development (Visual Studio).

Steve Ballmer replaced Gates as CEO in 2000 and later envisioned a "devices and services" strategy. This unfolded with Microsoft acquiring Danger, Inc. in 2008, entering the personal computer market for the first time in June 2012 with the launch of the Microsoft Surface, and later forming Microsoft Mobile through the acquisition of Nokia's devices and services division. Since Satya Nadella took over as CEO in 2014, the company has scaled back on hardware and instead focused on cloud computing, a move that helped the company's shares reach their highest value since December 1999. Under Nadella's direction, the company has also heavily expanded its gaming business to support the Xbox brand, establishing the Microsoft Gaming division in 2022, dedicated to operating Xbox in addition to its three subsidiaries (publishers). Microsoft Gaming is the third-largest gaming company in the world by revenue as of 2024.

In 2018, Microsoft became the most valuable publicly traded company in the world, a position it has repeatedly traded with Apple in the years since. In April 2019, Microsoft reached a trillion-dollar market cap, becoming the third U.S. public company to be valued at over $1 trillion after Apple and Amazon, respectively. As of 2024, Microsoft has the third-highest global brand valuation.

Microsoft has been criticized for its monopolistic practices and the company's software has been criticized for problems with ease of use, robustness, and security.

Microsoft is one of only two U.S.-based companies that have a prime credit rating of AAA.

Microsoft recognizes seven trade unions representing 1,750 workers in the United States at its video game subsidiaries Activision Blizzard and ZeniMax Media. U.S. workers have been vocal in opposing military and law-enforcement contracts with Microsoft. Bethesda Game Studios is unionized in Canada. Microsoft South Korea recognizes its union since 2017. German employees have elected works councils since 1998.

A studio is an artist or worker's workroom. This can be for the purpose of acting, architecture, painting, pottery (ceramics), sculpture, origami, woodworking, scrapbooking, photography, graphic design, filmmaking, animation, industrial design, radio or television production broadcasting or the making of music and financial services administration. The term is also used for the workroom of dancers, often specified to dance studio.

The word studio is derived from the Italian: studio, from Latin: studium, from studere, meaning to study or zeal.

The French term for studio, atelier, in addition to designating an artist's studio is used to characterize the studio of a fashion designer.

Studio is also a metonym for the group of people who work within a particular studio.

A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth".

The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called surface, sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface.

The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces of physical objects. For example, in analyzing the aerodynamic properties of an airplane, the central consideration is the flow of air along its surface. The concept also raises certain philosophical questions—for example, how thick is the layer of atoms or molecules that can be considered part of the surface of an object (i.e., where does the "surface" end and the "interior" begin), and do objects really have a surface at all if, at the subatomic level, they never actually come in contact with other objects.
