Android the best selling mobile operating system was created by Android.inc initially and then Google acquired it in 2005. First Google android phone was announced in 2008 . Android being so popular among people and making their lives sweet, so the versions of android are named after popular deserts.

When Apple unveiled its new iPhone 7 last week, Senior Vice President of Hardware Engineering Phil Schiller called the device's camera one of the most advanced ever put in a smartphone.  Cameras in phones are so commonplace now that users take them for granted, but improving the picture-taking capabilities of the newest devices means cramming a lot of tech into a small, and thin, package. From the  first cellphones with a camera  was the Nokia 7650, released in 2002 to  the Samsung Galaxy Note 7, which launched last month, has a processor similar to that found in a laptop computer and has 853,000 times as much data-storage space as the Nokia 7650.Upgrading the cameras in smartphones typically requires improving the sensors that pick up the image . Even though pictures taken on smartphones are good, digital SLRs still have an edge in some areas. This can be partly explained by the physics of gathering light onto an image. The aperture of the lens. However, softwa...

The term 'computer generation' is often used in relation to the hardware of computers. Each phase of computer development is known as a separate generation of computers. Each phase of development is characterised by type of switching circuits it utilises. Most computers today use the idea of ' stored program computer ' that was proposed by Dr. John Von Neumann in 1945. The Von Neumann architecture is based on three key concepts that are : Data and instructions (program) are stored in a single read-write memory. The memory contents are addressable by locations. Execution takes place in a sequential fashion i.e. from one instruction to the next unless modified explicitly. The First Generation Computers (1949-55) The first generation computers used thermionic valves (vacuum tubes) and machine language was used for giving instructions. The computers of this generation were very large in size and had high electricity consumption. Electric failures occur...
