how do you convert from decimal to binary? - (ANSWER)divide the decimal
number by increments of 2, the binary number will be the remainders of the
divisions taken from the bottom up
how do you convert from a decimal (base 10) to an octal number? -
(ANSWER)divide by 8 and take the remainders
(divide the decimal number by the base you want to convert to)
hexadecimal numbers - (ANSWER)0-9, A, B, C, D, E, F
A= 10
B=11
C= 12
D= 13
E= 14
F = 15
what does the MSB (most significant bit) of a number represent? - (ANSWER)0:
positive
1: negative
logic gates - (ANSWER)
, 1's Complement - (ANSWER)MSB = 0: the number is positive
the remaining n-1 bits represent the magnitude
MSB = 1: the number is negative
the remaining n-1 bits do not represent the magnitude
to change the sign- invert all the bits
2's Complement - (ANSWER)MSB = 0: the number is positive and the remaining n-
1 bits represent the magnitude
MSB = 1, the number is negative, and the remaining n-1 bits DO NOT represent
the magnitude
-to change the sign, invert all the bits and add 1 to the LSB
gray code - (ANSWER)allows only one bit to change between successive numbers
BCD code - (ANSWER)binary coded decimal
-encoding scheme that encodes using the 4 bit binary equivalent
in a multiple input AND gate, what happens to an open input and why? -
(ANSWER)an open input will float high
