Consumer electronics in the context of "Transistor-transistor logic"

A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster.

A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computers and users.

Sony Group Corporation, commonly referred to as Sony, is a Japanese multinational conglomerate headquartered at Sony City in Minato, Tokyo, Japan. The Sony Group encompasses various businesses, including electronics (Sony Corporation), imaging and sensing (Sony Semiconductor Solutions), film (Sony Pictures Entertainment), music (Sony Music Group and Sony Music Entertainment Japan), video games (Sony Interactive Entertainment), and others.

Sony was founded in 1946 as initially Tokyo Tsushin Kogyo K.K. by Masaru Ibuka and Akio Morita. In 1958, the company adopted the name Sony Corporation. Initially an electronics firm, it gained early recognition for products such as the TR-55 transistor radio and the CV-2000 home video tape recorder, contributing significantly to Japan's post-war economic recovery. After Ibuka's retirement in the 1970s, Morita served as chairman until 1994, overseeing Sony's rise as a global brand recognized for innovation in consumer electronics. Landmark products included the Trinitron color television, the Walkman portable audio player, and the co-development of the compact disc.

Panasonic Holdings Corporation is a Japanese multinational electronics manufacturer, headquartered in Kadoma, Japan. It was founded in 1918 as Matsushita Electric Housewares Manufacturing Works in the Fukushima ward of Osaka by Kōnosuke Matsushita. The company was incorporated in 1935 and renamed Matsushita Electric Industrial Co., Ltd., and changed its name to Panasonic Corporation in 2008. In 2022, it reorganized as a holding company and adopted its current name.

In addition to consumer electronics, for which it was the world's largest manufacturer in the late 20th century, Panasonic produces a wide range of products and services, including rechargeable batteries, automotive and avionic systems, industrial equipment, as well as home renovation and construction. The company is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX 100 indices, with a secondary listing on the Nagoya Stock Exchange.

A microphone, colloquially called a mic (/maɪk/), or mike, is a transducer that converts sound into an electrical signal. Microphones are used in telecommunication, sound recording, broadcasting, and consumer electronics, including telephones, hearing aids, and mobile devices.

Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically need to be connected to a preamplifier before the signal can be recorded or reproduced.

Consumer IR, consumer infrared, or CIR is a class of devices employing the infrared portion of the electromagnetic spectrum for wireless communications. CIR ports are commonly found in consumer electronics devices such as television remote controls, PDAs, laptops, computers, and video game controllers.

The functionality of CIR is as broad as the consumer electronics that carry it. For instance, a television remote control can convey a "channel up" command to the television, while a computer might be able to surf the internet solely via CIR. The type, speed, bandwidth, and power of the transmitted information depends on the particular CIR protocol employed.

Computer-mediated communication (CMC) is defined as any human communication that occurs through the use of two or more electronic devices. While the term has traditionally referred to those communications that occur via computer-mediated formats (e.g., instant messaging, email, chat rooms, online forums, social network services), it has also been applied to other forms of text-based interaction such as text messaging. Research on CMC focuses largely on the social effects of different computer-supported communication technologies. Many recent studies involve Internet-based social networking supported by social software.

A small domestic appliance (also known as a small electric appliance or minor appliance or simply a small appliance, small domestic or small electric) is a portable or semi-portable machine, generally used on table-tops, counter-tops or other platforms, to accomplish a household task. Examples include microwave ovens, kettles, toasters, humidifiers, food processors and coffeemakers. They contrast with major appliances (known as "white goods" in the UK), such as the refrigerators and washing machines, which cannot be easily moved and are generally placed on the floor. Small appliances also contrast with consumer electronics (British "brown goods") which are for leisure and entertainment rather than purely practical tasks. Small appliances are often mechanically simple devices, typically built around a single heating element, fan, set of blades or similar mechanism with only a few mechanical linkages, which generally makes them straightforward to repair.

A big-box store, a hyperstore, a supercenter, a superstore, or a megastore is a physically large retail establishment, usually part of a chain of stores. The term sometimes also refers, by extension, to the company that operates the store. The term "big-box" references the typical appearance of buildings occupied by such stores.

Commercially, big-box stores can be broken down into two categories: general merchandise (examples include Walmart and Target) and specialty stores (such as Home Depot, Barnes & Noble, IKEA or Best Buy), which specialize in goods within a specific range, such as hardware, books, furniture or consumer electronics, respectively. In the late 20th and early 21st centuries, many traditional retailers and supermarket chains that typically operate in smaller buildings, such as Tesco and Praktiker (the latter which is defunct since 2014), opened stores in the big-box-store format in an effort to compete with big-box chains, which are expanding internationally as their home markets reach maturity.
