IMT-2000 (International Mobile Telecommunications-2000) is the official ITU designation for 3G standards. The '2000' referred to both the frequency band (around 2000 MHz) and the target year of deployment. This is the standard technical name for 3G.

NTT DOCOMO launched the world's first pre-commercial 3G network in May 2001 in Japan. This was part of their FOMA (Freedom of Mobile Multimedia Access) service, which was based on W-CDMA technology and preceded full commercial launch.

NTT DOCOMO also launched the world's first commercial 3G service in October 2001, building on their earlier pre-commercial launch. This full commercial deployment made Japan the first country to have operational 3G networks available to the public.

MTNL (Mahanagar Telephone Nigam Limited) launched India's first 3G services in December 2008, ahead of private operators. BSNL followed shortly after in 2009.

Samsung launched Bada OS in 2010 as their proprietary mobile operating system. It was designed to compete with iOS and Android, running on Samsung's own Wave series smartphones. Debian is a Linux distribution for computers, GNOME is a desktop environment, and Maemo was Nokia's platform.

Nokia developed Maemo for their smartphones and internet tablets, particularly the N900 and N810 devices. It was a Linux-based platform designed for high-end mobile devices. Symbian was also Nokia's but was a different platform, Garnet is associated with Palm, and Android is Google's OS.

In 2010, Symbian had the largest worldwide market share among mobile operating systems, particularly due to Nokia's dominance in the global smartphone market. Linux was gaining ground but wasn't the largest, Windows Mobile and Palm WebOS had smaller market shares.

Android is an open-source mobile operating system developed by Google. It provides developers with extensive access to phone hardware and software features through its APIs and open-source nature. Garnet is Palm OS related, Maemo is Nokia's, and Limo is a different Linux-based mobile OS.

BREW (Binary Runtime Environment for Wireless) was developed by QUALCOMM as an application development platform that enabled native application development in C and C++ for mobile phones. It was widely used on CDMA phones. Garnet is from PalmSource, Symbian is Nokia's platform, and Maemo is also Nokia's.

Apple's iPhone uses iPhone OS (which later became iOS), a specialized mobile operating system derived from macOS but optimized for touchscreen mobile devices. Mac OS X is for desktop computers, Symbian is Nokia's platform, and BREW is QUALCOMM's platform.

AT&T merged with BellSouth Corporation in 2006, which was a significant corporate acquisition in the telecommunications industry.

The Iris Browser was based on the WebKit rendering engine and was designed to provide a better mobile web experience.

ISRO (Indian Space Research Organisation) was established on August 15, 1969, under the Department of Atomic Energy. It has since become one of the world's leading space agencies, known for missions like Chandrayaan and Mangalyaan.

India's first satellite, Aryabhata (launched in 1975), was launched with Soviet assistance. The USSR provided the launch vehicle and support, as India's space program was in its early stages. USA, Germany, and UK were not involved in this specific launch.

Bhuvan is ISRO's satellite mapping tool, similar to Google Earth. It provides high-resolution imagery of India and uses Indian satellite data. Earth Map (A), Bhumi (C), and ISRO Earth (D) are not the actual names of this ISRO product.

Chandrayaan-1 was India's first unmanned lunar probe, launched in 2008. The name combines 'Chandra' (Moon) and 'Yaan' (craft). Lunar Lander-1 (A), Chandra-1 (B), and Lunar Mission-1 (D) are incorrect names for this mission.

Satish Dhawan Space Centre (SDSC) at Sriharikota is ISRO's primary launch station. Formerly called SHAR, it was renamed after Dr. Satish Dhawan, a key figure in Indian space research. Bhabha (A), Vikram Sarabhai (B), and Rakesh Sharma (C) are space centers or figures but not the primary launch site.
