Binary shifting Flashcards
1
Q
What is binary shifting (bitwise shifting)
A
A binary shift means moving each bit in the direction defined by the amount defined. Since we work in bytes any bits that go outside our block of 8 are lost forever
2
Q
Shifting left
A
Take a 1 byte binary value
e.g 00101000
and shift it left by 2 bits
10100000
3
Q
Shifting right
A
Take a 1 byte binary value
e.g 00101000
and shift it right by 3 bits
00000101
4
Q
what happens when we shift bits right
A
It halves its value
5
Q
what happens when we shift bits left
A
it doubles its value
6
Q
Shift the following Binary value 2 places to the right:
00111100
A
00001111
7
Q
Shift the following Binary value 1 place to the left:
11011001
A
10110010
8
Q
Divide the following Binary by 2:
00011101
A
00001110
9
Q
Multiply the following Binary value by 8:
00011101
A
11101000
