Suppose that smartphone a has 256 mb ram and 32 gb rom, and the resolution of its camera is 8 mp; smartphone b has 288 mb ram and 64 gb rom, and the resolution of its camera is 4 mp; and smartphone c has 128 mb ram and 32 gb rom, and the resolution of its camera is 5 mp. determine the truth value of each of these propositions.
a) smartphone b has the most ram of these three smartphones.
b) smartphone c has more rom or a higher resolution camera than smartphone b.
c) smartphone b has more ram, more rom, and a higher resolution camera than smartphone a.
d) if smartphone b has more ram and more rom than smartphone c, then it also has a higher resolution camera.
e) smartphone a has more ram than smartphone b if and only if smartphone b has more ram than smartphone a.

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.
