Technology General Knowledge

According to the Oxford English Dictionary, the word robotics was first used in print by Isaac Asimov in his science fiction short story "Liar!" published in May 1941 in Astounding Science Fiction.

Telex is a telecommunication system that combines 'teleprinter' and 'exchange' to enable direct message transmission between teleprinters. The term derives from the technology's ability to automatically route and exchange telegraphic messages.

FM stands for Frequency Modulation, which is a method of encoding information in a carrier wave by varying its frequency. This is different from AM (Amplitude Modulation) which varies the signal's strength instead.

'Small is Beautiful' by E.F. Schumacher (note: spelled correctly as Schumacher, not Shumaker as in the option) is a seminal work on appropriate technology and sustainable development. The book argues that smaller-scale technologies are more appropriate for developing countries and environmental sustainability.

Telecom signals, being electromagnetic waves, travel at the speed of light in vacuum (approximately 3×10^8 m/s). This includes radio signals, microwave transmissions, and optical fiber communications.

This question refers to the printograph, a historical photo printing technology. The exact introduction date of this specific technology in 1956 is highly specialized knowledge that may not be widely documented.

Hotmail was one of the first webmail services and was acquired by Microsoft in 1997. It was later rebranded as Outlook.com, but remained Microsoft's flagship free email service. Gmail is owned by Google, Yahoo Mail by Yahoo, and there is no 'Micro mail'.

The picture tube (also called a cathode ray tube or CRT) is the component in traditional television sets that converts video signals into visible images. It uses electron beams to illuminate phosphors on the screen, creating the pictures we see.

Remington was indeed a famous manufacturer of typewriters and played a significant role in the development and popularization of typewriters in business and personal use. The company was known for quality office equipment including typewriters.

Holography is the technique used for creating three-dimensional photographs called holograms. It uses light diffraction and interference patterns to record and display 3D images, capturing both intensity and phase information of light waves.

The first public telephone system was established in Paris in 1879, shortly after the initial telephone exchanges were developed. This was one of the earliest public telephone networks, making Paris historically significant in telecommunications development.

Cyberspace is sometimes referred to as 'Infoban' (short for information bandwidth), representing the virtual space where digital communication and information exchange occurs. This alternative term emphasizes the information-carrying capacity of the digital realm.

In 1977, General Electric established one of the first commercial optical fiber cable systems in California. While the first live telephone traffic through fiber optics occurred in Chicago that same year, California was indeed a major early deployment site for fiber optic technology.

Xerox developed the computer mouse at their Palo Alto Research Center (PARC) in the 1970s, building on earlier work by Douglas Engelbart. The mouse became a key component of the Xerox Alto computer and later influenced the Apple Lisa and Macintosh.

Supersonic refers to speeds exceeding the speed of sound (Mach 1). Aircraft like the Concorde and fighter jets are supersonic planes. 'Ultrasonic' refers to sound frequencies above human hearing, not aircraft speed.

Wi-Fi (Wireless Fidelity) is the technology that allows wireless connections between devices like laptops and local area networks. It uses radio waves to provide wireless high-speed Internet and network connections. LAN is wired, while 'Configure' and 'Booting' are processes, not technologies.

The first commercial cellular phone service began in Chicago in 1983, operated by Ameritech. This was the launch of the first generation (1G) cellular network in the United States, using the AMPS standard.

Radio broadcasting in India began in 1927 with private radio clubs. The first official broadcast was by the Indian Broadcasting Company (later All India Radio) in 1927. State-sponsored broadcasting began in 1930.

 Micro wave is the medium of satellite communication.

Karl Jansky discovered radio waves from space in 1932 while working at Bell Labs. He detected radio noise coming from the Milky Way galaxy, founding the field of radio astronomy. This was the first detection of extraterrestrial radio waves.

In 1881, the first telephone satellite was launched in India.

Intelsat-1 (nicknamed 'Early Bird') was the first commercial communication satellite, launched in 1965. It provided the first regular transatlantic satellite communication service. INSAT satellites are Indian communication satellites that came much later.
