1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral.

In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions.

Fourteen or 14 may refer to:

• 14 (number), the natural number following 13 and preceding 15
• one of the years 14 BC, AD 14, 1914, 2014

2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and the only even prime number.

Because it forms the basis of a duality, it has religious and spiritual significance in many cultures.

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.

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 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. They 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 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). 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 travelling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes.

Lenovo Group Limited, trading as Lenovo ( lə-NOH-voh, Chinese: 联想; pinyin: Liánxiǎng), is a Chinese multinational technology company specializing in designing, manufacturing, and marketing consumer electronics, personal computers, software, business solutions, and related services. Its global headquarters are in Beijing, and Morrisville, North Carolina, United States; it has research centers at these locations, elsewhere in China, in Stuttgart, Germany, and in Yamato, Japan.

Lenovo originated as an offshot of a governmental research institute. Then known as Legend, the company developed numerous electronics before focusing on personal computers. Co-founder Liu Chuanzhi incorporated Legend in Hong Kong in an attempt to raise capital and was successfully permitted to build computers in China. It listed on the Hong Kong Stock Exchange in 1994 and became the largest PC manufacturer in China and eventually in Asia; they were also domestic distributors for HP printers, Toshiba laptops, and others. After the company rebranded itself to Lenovo, it acquired IBM's PC business including its ThinkPad line in 2005, after which it rapidly expanded abroad. In 2013, Lenovo became the world's largest personal computer vendor by unit sales for the first time, a position it still holds as of 2024.

Products manufactured by the company include desktop computers, laptops, tablet computers, smartphones, workstations, servers, supercomputers, data storage devices, IT management software, and smart televisions. Its best-known brands include its ThinkPad business line of notebooks, the IdeaPad, Yoga, LOQ, and Legion consumer lines of notebooks, and the IdeaCentre, LOQ, Legion, and ThinkCentre lines of desktops. Lenovo is also part of a joint venture with NEC, named Lenovo NEC Holdings, that produces personal computers for the Japanese market. The company also operates Motorola Mobility which produced smartphones.

Yoga (; Sanskrit: योग, Sanskrit pronunciation: [joːɡɐ] , lit. "yoke" or "union") is a group of physical, mental, and spiritual practices or disciplines that originated in ancient India, aimed at controlling body and mind to attain various salvation goals, as practiced in the Hindu, Jain, and Buddhist traditions.

Yoga may have pre-Vedic origins, but is first attested in the early first millennium BCE. It developed as various traditions in the eastern Ganges basin drew from a common body of practices, including Vedic elements. Yoga-like practices are mentioned in the Rigveda and a number of early Upanishads, but systematic yoga concepts emerge during the fifth and sixth centuries BCE in ancient India's ascetic and Śramaṇa movements, including Jainism and Buddhism. The Yoga Sutras of Patanjali, the classical text on Hindu yoga, samkhya-based but influenced by Buddhism, dates to the early centuries of the Common Era. Hatha yoga texts began to emerge between the ninth and 11th centuries, originating in tantra.

Yoga is practiced worldwide, but "yoga" in the Western world often entails a modern form of Hatha yoga and a posture-based physical fitness, stress-relief and relaxation technique, consisting largely of asanas; this differs from traditional yoga, which focuses on meditation and release from worldly attachments. It was introduced by gurus from India after the success of Swami Vivekananda's adaptation of yoga without asanas in the late 19th and early 20th centuries. Vivekananda introduced the Yoga Sutras to the West, and they became prominent after the 20th-century success of hatha yoga.
