1, the number in the computer is represented how?
The number of binary representation
Decimal
Hex
Convert decimal numbers to binary: In addition to the anti-modulo 2 is written in binary decimal, certain wrote 0, bottoming out
16 is represented as binary: 10000
Binary to octal: three each corresponding to an octal
Binary to Hex: every four corresponds to a hexadecimal
2, the number of logic on how it is calculated?
2.1, and operations:
Truth table as follows:
A B F
0 0 0
0 1 0
1 0 0
1 1 1
2.2, or operations:
Truth table as follows:
A B F
0 0 0
0 1 1
0 1 1
1 0 1
1 1 1
2.3, non-operational
Truth table as follows:
A F
0 1
1 0
2.4, exclusive-OR operation (the same is 0, 1 is different)
Truth table as follows:
A B F
0 0 0
0 1 1
1 0 1
1 1 0
2.5, or the same operation (the same is 1, is different from 0)
Truth table as follows:
A B F
0 0 1
0 1 0
1 0 0
1 1 1
3, the number of physical computing is how to achieve?
XOR gate
AND gate
OR
Summary: The number involved in computing, can be converted to a binary number
Binary arithmetic, you can use basic Boolean operations to achieve
Basic Boolean operations can be implemented by circuitry
The role of the truth table: determining whether an expression is true or valid
