In a mask operation the bit pattern in B is used to clear ce

In a mask operation, the bit pattern in B is used to clear certain bits in A. If a bit in B is set to 1, that same position in A gets 0, otherwise that bit in A keeps its previous value. TRUE [] FALSE [] It is impossible to have overflow in the case of arithmetic shift left because the value after shift is smaller than the value before shift. TRUE [] FALSE[] An overflow occurs in the case of logical shift right if the two most significant bits of the value are the same. TRUE [] FALSE [] In a selective clear operation, the bit pattern in B is used to clear certain bits in A. If a bit in B is set to 1, that same position in A gets set to 1, otherwise it is unchanged. TRUE [] FALSE [] A decoder with 32 inputs has 4 outputs. TRUE [] FALSE[] When a signed binary number is represented in sign-magnitude, the left-most bit is the sign bit and the remaining bits are the magnitude bits. TRUE [] FALSE [] In the l\'s complement form, a negative number is the l\'s complement of the corresponding positive number. TRUE [] FALSE [] Decimal values of positive and negative numbers in the 2\'s complement form are determined by summing the weights in all bit positions where there are is and ignoring those positions where there arc zeros. The weight of the sign bit in a negative number is given a negative value. TRUE [] FALSE [] The ASCII is a 7-bit alphanumeric code that is widely used in computer systems for input and output of information. TRUE [] FALSE [] In the sign-magnitude form, a negative number has the same magnitude bits as the corresponding positive number but the sign bit is a 1 rather than a zero. TRUE [] FALSE []

Solution

1. False (it wont be happen in this case)
2.True
3.true
4.False
5.True
6.True
7.True
8. Flase
9.True becausse, asci is a 7-bit alphanumberic code.
10.True it will have sign bit rather than zero
