Consider the relation r(a, b,c, d) with fds a -> b, c -> d, ad -> c, bc -> a. check for both bcnf and 3nf status. which of the following is the most accurate summary of the results? o ris in bcnf and 3nf. no normalization is necessary. o ris in 3nf but not in bcnf. we should try normalizing to bcnf, but this results in information being lost. as such, we stay with the original schema. o ris in bcnf but not in 3nf. since bcnf is the stricter normalization standard we do not need to normalize further. ris in neither bcnf nor 3nf. we need to normalize until the relations are in bcnf and/or 3nf.

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.

What would be the address of the cell, which is at the intersection of the second row and the third column in a worksheet?

Ican’t open these when it’s just a comment. someone pls explain why this is happening
