Data representaion

AND Logic gate
1. 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
1. AND logic gate
  1. 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)
2. OR logic gates
  1. 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
3. NOT Logic gate
  1. The Not logic gate has only one input whatever the input is the output will be the opposite.
4. 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
1. 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.
2. 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
