Units and Binary

Units and Binary

1. Order- Bit, Nibble, Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte

2. When you convert to bigger byte, you divide and when you get to a smaller byte, you multiply

3. 0+0=0, 1+0=1, 1+1=0 carry 1, 1+1+1=1 carry 1

4. Hexadecimal rules- 1=1 2=2 3=3 4=4 5=5 6=6 7=7 8=8 9=9 10=A 11=B 12=C 13=D 14=E 15=F

5. When converting binary to hex, you split the 8 bit binary number into two nibbles and you work out the denary number for each nibble. You should have columns with 8,4,2 and 1. You then put them together as a hexadecimal number

6. When converting hex to binary, you have to split the characters and work out the nibble for each hexadecimal number. You should have columns for 8,4,2 and 1 After that, you put them together to get your 8 digit binary number

7. When converting hex to denary, you have to use the columns 1,16,256 and 4096. Then, you have to put the hexadecimal number into the columns and multiply each number by the column

8. An ASCII code is a character encoding standard for electronic devices. It is used to represent text in computers, telocommunication equipment and other devices. It is a 7 bit binary number that represents 127 different characters
