Explain the hardware‚ software and peripheral components of a computer system and the functional relation between these components. Fig: functions of the operating systems (1) 1- Hardware Hardware consists of physical equipment of the computer. We distinguish equipment within the Case such as: Power supply: it is the equipment that receives electricity from a DC current and converts it to a alternative current AC for the needs of the computer. The power supply may depends on the motherboard

Abstract The purpose of this experiment was to perform a liquid-liquid extraction method to extract the caffeine from the tea bags that were provided‚ and then recrystallize the caffeine. The solvents used in the experiment were an aqueous sodium carbonate and dichloromethane (DCM). Anhydrous calcium chloride pellets were used to dry the solution and emulsion layer and the DCM was then decanted. After washing the anhydrous calcium chloride pellets with more DCM‚ the solvent was evaporated‚ leaving

tiles. But the problem‚ is eggshell can be a component of making tiles? Background of the Study This study was conducted to ensure another component of making tiles. With the lack of components for making tiles‚ the researcher suggested shells like eggshells to be used as component of making tiles. From the previous project‚ some shells were used as a component of making tiles. The reason on why the researcher used and considered eggshells as a component of making tile is because eggshell is a kind

Organelles are the various components of a cell with a specific structure and function and are linked to miniature organs. These include: Mitochondria: These are small components within cells that perform different important functions in order to keep the body healthy. They make the energy that cells need to do to work correctly. An example of this is
