Describe any one of the following object giving definition, diagrams, components and working of smartphone or water purifier:
A smartphone is a cellular telephone with an integrated computer and other pictures not originally associated with basic telephone, for instance an operating system browsing and ability to run software applications.
NAND flash, display, application, processors, DRAM, baseband, camera module, touch panel and battery are some components within a smart phone.
Along with processor, smartphone also have computer chips that provide functionality. Phones in cameras have high resolution image sensor, just like digital cameras. order cheap support complex function such as in browsing the internet, sharing multimedia files are playing music.
Unlike traditional cell phone, smartphones with their memories, allow individual users to install, configure, and runs applications. Smartphones are mini radios, sending and receiving radio signals. Cell phone network are divided into specific areas cells, each one of which has an antenna that receives and transmits cell phone sinais.
A water purifier is a device for removing unwanted substance such as bacteria, germs or harmful chemicals from drinking water, thereby purifying it. The method used to purify water to make it fit for human consumption includes filtration, sediments, distillation, biologically active carbon, flocculantion , chlorination and the use of reverse osmosis and ultra Violet light.
Water purification through UV is an effective method for disinfecting water for consumption. UV system destroy harmful microorganisms without adding Chemicals are changing the water taste or odour. The UV spectrum includes wavelength from 2000 to 3900 and angstrom units. In a typical operation, water enters the inlet of a UV lamp and flow through the annular space between the qartz sleeve and the outside chamber wall. The irradiated water leaves through the outlet nozzle.
UV purification itself is not enough to purify water down to drinking water purpose as it is only effective for treating bacteria and viruses. To eliminate contaminants such as chlorine, heavy metals etc., UV system are oftained paired with reverse osmosis are activated charcoal to complete the purification process.
