Identify the correct statement with respectto normalization.
? normalization is a formaltechnique that can be used only at the starting phase of thedatabase design.
? normalization can be usedas a top-down standalone database design technique.
? the process ofnormalization through decomposition must achieve the losslessjoin
property at any cost whereas the dependency reservation propertyis sometimes
sacrificed.

Check my work the microprocessor is a(n) circuit, which is designed to process data based on a set of instructions. most desktop and laptop devices contain a microprocessor based on the standard. most tablets and smartphones contain processors based on technology. a microprocessor's circuitry is designed to perform a limited number of tasks contained in its set. during processing, an instruction is loaded into the processor's unit. data is loaded into registers in the processor's where arithmetic and logic operations are performed. microprocessor performance can be measured by its speed. other factors affecting overall processing performance include word size, cache size, and instruction set complexity. most digital devices contain only one microprocessor chip, but today's multi- processors contain circuitry that supports parallel processing. computers contain various kinds of memory. random memory is a special holding area for data, program instructions, and the system. it stores data on a temporary basis until the processor makes a data request. ram is different from disk storage because it is , which means that it can hold data only when the computer power is turned on. computers also contain read- memory, which is a type of non-volatile memory that provides a set of "hard-wired" instructions, called the loader, that a computer uses to boot up.

1. before plugging in a new device to a computer you should unplug all other devices turn off the computer turn on the computer 2. many of the maintenance tools for a computer can be found in the control panel under administrative tools display personalization

Im doing this last minute and literally none of my neighbors or people that my dad works with use excel so if anyone could me make up an example
