Data representaion
- AND Logic gate
- This gate has a two input nodes and one output node. The input can ether be 1 or 0. The output will only be 1 if both the inputs are 1 otherwise the output will be 0.
- Binary logic
- AND
logic gate
- This gate has two inputs and one out put. The
output will only by 1 if both the inputs are 1 over
wise the out put will be 0 (vies versa)
- OR logic gates
- An OR gate has two inputs and one output. If
ether one or both inputs are 1 then the
output will be one, other wise it will be 0
- NOT Logic gate
- The Not logic gate has only
one input whatever the input
is the output will be the
opposite.
- Data in computer sis represented as 1 and
0 because it is extremely difficult for the
computer to mistake a 1 for a 0
- Units
- A bit is a single binary digit. A Nibble is 4 binary digits. A Byte is 8
binary digits (2 nibbles or 8 bits). A Kilobyte is approximately 1024
bytes. a Mega byte is approximately 1000 kilobytes. A gigabyte is
approximately 1000 megabytes. A Terabyte is approximately 1000
gigabytes.
- Data needs to be converted into binary because it makes it
easier for the computer to distinguish. a computer finds it
harder to mistake a 1 for a 0 (vies versa) then mistaking 4.76
for 4.77
