What is the best explanation for why digital data is represented in computers in binary? a. the binary number system is the only system flexible enough to allow for representing data other than numbers. b. it's easier, cheaper, and more reliable to build machines and devices that only have to distinguish between binary states. c. it typically takes fewer digits to represent a number in binary when compared to other number systems (for example, the decimal number system) d. it's impossible to build a computing machine that uses anything but binary to represent numbers

B.  

Digital data is represented in computers in binary because it is more reliable to build machines and devices that only have to distinguish between binary states. Aside from that, it's easier and cheaper as binary can represent more complex and higher level abstractions, including but not limited to numbers, colors and characters.  

after lydia compare her check register to her bank statement, and the ending balances do not seem to match. then, she must make a bank reconciliation by putting the data all together.

to do this, she need to determine the bank ending balance. after, add the deposits in transit then deduct the outstanding checks. moreover, if the actual checkbook balance does not equal this number, check again for transporting errors by subtracting the balances and add the difference to nine. sometimes, a mathematical error can happen but a bank reconciliation is a great tool to resolve the discrepancies.
