Answer the following questions. (i) Find the bit-pattern which represents the following characters:4 marks Ate (ii) Thehexadecimalrepresentationofatwocharactersbitpatternis4151.4 marks What characters does this represent? (d) Supposewehaveacomputerinwhicheveryintegermustbestoredin7-bits with the same number of negative and non-negative integers (i.e. as signed integers) find the following.
