Baud Rate ANS:The maximum possible number of signal changes that can occur in a wire per second. Bit Rate ANS:The number of bits that can be sent down a wire per second. Integer ANS:A whole number that can be positive, negative or zero. Examples: -3, 0, 7, 2013588. Natural (Number) ANS:A whole number that is either positive or zero. Examples: 0, 1, 2, 100, 67238. Rational (Number) ANS:Any number that can be represented as the fraction 'a/b' where 'a' and 'b' are both integers. ...
