Samsung



Samsung is a South Korean multinationalconglomerate company headquartered in Samsung TownSeoul. It comprises numerous subsidiaries and affiliated businesses, most of them united under the Samsung brand, and is the largest South Korean chaebol (business conglomerate).
Samsung was founded by Lee Byung-chul in 1938 as a trading company. Over the next three decades, the group diversified into areas including food processing, textiles, insurance, securities and retail. Samsung entered theelectronics industry in the late 1960s and the construction and shipbuilding industries in the mid-1970s; these areas would drive its subsequent growth. Following Lee's death in 1987, Samsung was separated into four business groups – Samsung Group, Shinsegae Group, CJ Group and Hansol Group. Since 1990s, Samsung has increasingly globalized its activities, and electronics, particularly mobile phones and semiconductors, have become its most important source of income.


History



In 1938, Lee Byung-chull (1910–1987) of a large landowning family in the Uiryeong county came to the nearby Daegucity and founded Samsung Sanghoe (삼성상회, 三星商會), a small trading company with forty employees located in Su-dong (now Ingyo-dong).[15] It dealt in groceries produced in and around the city and produced its own noodles. The company prospered and Lee moved its head office to Seoul in 1947. When the Korean War broke out, however, he was forced to leave Seoul and started a sugar refinery in Busan named Cheil Jedang. After the war, in 1954, Lee founded Cheil Mojik and built the plant in Chimsan-dong, Daegu. It was the largest woolen mill ever in the country and the company took on the aspect of a major company.

History


Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1000 employees to work on the highly confidential "Project Purple", including Jonathan Ive, the designer behind the iPhone. Apple CEO Steve Jobs steered the original focus away from a tablet, like the iPad, and towards a phone.Apple created the device during a secretive collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months.

Google Nexus

Google Nexus



Google Nexus is a line of consumer electronic devices that run the Android operating systemGoogle manages the design, development, marketing, and support of these devices, but some development and all manufacturing are carried out by partnering original equipment manufacturers (OEMs). The product family consists mostly of mobile devices—six smartphones and four tablet computers have been released to date. As of October 2014, the devices currently available in the line are the Nexus 5 smartphone (made with partner LG Electronics), Nexus 6 smartphone (made with Motorola Mobility), Nexus 9 tablet (made with HTC), and Nexus Player set-top box (made with Asus).

Devices in the Nexus line are considered Google's flagship Android products. They contain little to no manufacturer or wireless carrier modifications to Android (such as custom graphical user interfaces), although devices sold through carriers are sometimes SIM locked and may bear some extra branding. Nexus 6 devices sold through AT&T, for example, are SIM locked and feature a custom boot splash screen and a logo on the back of the device, despite having otherwise identical hardware to the unlocked variant. The Verizon Galaxy Nexus featured a Verizon logo on the back and received software updates at a slower pace than the unlocked variant, though it featured different hardware to accommodate Verizon's CDMA network. All Nexus devices feature an unlockable bootloader to allow further development and end-user modification. Nexus devices are often among the first Android devices to receive updates to the operating system
