 Test on data representation
 1.   All data manipulated by computers must be in format. 2.   Computers cannot process images because they have no way of representing pictures. True False 3.   The decimal system has a base of 10, while the hexadecimal system has a base of: 2 8 16 4 4.   One of the following numbers is illegal in base 4: 1234 3320 10000 111111 5.   The decimal equivalent of the number (200)5 is : 125 1000 600 None of the above 6.   The decimal equivalent of the number (200)3 is: 600 180 9 18 7.   The binary equivalent of the number (700)16 is: 000000000111 11100000000 0111 111000000 8.   The octal equivalent of the number (700)16 is: 1000 700 3400 7000 9.   The octal equivalent of the number (1100010)2 is: 310 142 304 320 10.   The hexadecimal equivalent of the number (1100010)2 is: 610 A4 62 None of the above 11.   The hexadecimal equivalent of the number (10)10 is: A 16 10 None of the above 12.   The binary equivalent of the number (20)10 is: 11001 10111 10101 10100 13.   The signed-magnitude binary representation of the number +27 is: 00011011 11111011 11011000 None of the above 14.   The signed-magnitude binary representation of the number -227 is: 11111111 10000000 01111111 None of the above 15.   Using 8-bits signed-magnitude representation, the range of numbers that can be represented is: -128 to +128 -255 to +255 -127 to +127 -256 to +256 16.   Using the same number of bits, both the signed-magnitude and 1's complement representations will have the same range. True False 17.   All signed-number representations suffer from the zero double representation problem. True False 18.   The 1's complement representation of signed-numbers is the most widely used in computers. True False 19.   The 2's complement representation of –34 is: 11100010 11011110 01100010 00100010 20.   Overflow can occur when adding two numbers with the same sign. True False 21.   A bit is added to data for error checking/detection. 22.   The code is the most popular binary codes for character representation in computers. 23.   The is a 16-bit code that can represent all the characters in all the languages of the world. 24.   The binary data 0000000 with even parity becomes: 00000000 10000000 00000001 None of the above 25.   The binary data 0000000 with odd parity becomes: 00000000 10000000 00000001 None of the above
