Laptop computers in the context of Computer screen

A lithium-ion battery, or Li-ion battery, is a type of rechargeable battery that uses the reversible intercalation of Li ions into electronically conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy density, and energy efficiency and a longer cycle life and calendar life than other types of rechargeable batteries. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991; over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In late 2024 global demand passed 1 terawatt-hour per year, while production capacity was more than twice that.

The invention and commercialization of Li-ion batteries has had a large impact on technology, as recognized by the 2019 Nobel Prize in Chemistry.Li-ion batteries have enabled portable consumer electronics, laptop computers, cellular phones, and electric cars. Li-ion batteries also see significant use for grid-scale energy storage as well as military and aerospace applications.

TravelMate is a line of business-oriented laptop computers manufactured by Acer. Of the various notebook series Acer has offered, the TravelMate is designated as a lightweight business and professional computer built to withstand day-to-day activities. TravelMate laptops are well received by reviewers, often, however, they are faulted for a lack of visual appeal. The TravelMate name was previously used by Texas Instruments, which sold its mobile computing division to Acer in 1997. The TravelMate mainly competes against business computers such as Asus's ExpertBook, Dell's Latitude and Vostro, Fujitsu's LifeBook, HP's EliteBook and ProBook, Lenovo's ThinkPad and ThinkBook, and Toshiba's Portégé and Tecra.

Dell Latitude is a line of laptop computers manufactured and sold by American company Dell Technologies. It is a business-oriented line, aimed at corporate enterprises, healthcare, government, and education markets; unlike the Inspiron and XPS series, which were aimed at individual customers, and the Vostro series, which was aimed at smaller businesses. The Latitude line directly competes with Acer's Extensa and TravelMate, Asus's ExpertBook, Fujitsu's LifeBook, HP's EliteBook and ProBook, Lenovo's ThinkPad and ThinkBook and Toshiba's Portégé and Tecra. The "Rugged (Extreme)", "XFR" and "ATG" models compete primarily with Panasonic's Toughbook line of "rugged" laptops.

In January 2025, Dell announced its intentions to gradually phase out their existing lineup of computer brands in favor of a singular brand simply named as "Dell" as part of the company's shift towards the next generation of PCs with artificial intelligence capabilities. The Latitude brand would be supplanted by the Dell Pro laptop line, which emphasizes professional-grade productivity and business-class computers.

Ubiquitous computing (or "ubicomp") is a concept in software engineering, hardware engineering and computer science where computing is made to appear seamlessly anytime and everywhere. In contrast to desktop computing, ubiquitous computing implies use on any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets, smart phones and terminals in everyday objects such as a refrigerator or a pair of glasses. The underlying technologies to support ubiquitous computing include the Internet, advanced middleware, kernels, operating systems, mobile codes, sensors, microprocessors, new I/Os and user interfaces, computer networks, mobile protocols, global navigational systems, and new materials.

This paradigm is also described as pervasive computing, ambient intelligence, or "everyware". Each term emphasizes slightly different aspects. When primarily concerning the objects involved, it is also known as physical computing, the Internet of Things, haptic computing, and "things that think".Rather than propose a single definition for ubiquitous computing and for these related terms, a taxonomy of properties for ubiquitous computing has been proposed, from which different kinds or flavors of ubiquitous systems and applications can be described.
