Aslo sometimes called Base 2
What is 1 single binary digit called?
A single binary 1 or 0 is called a Bit.
What is a binary number that is made up of 8 bits called?
For example: 00011011
8 bits is called a Byte.
Why do computers use the binary number system?
Compters are made up of tiny switches which can only ever be in two states “on” or “off”. Therefore a computer must interpret everything as either “ons” or “offs” we represent these as 1’s and 0’s.
What is the name for the number system that uses 10 digits (0 1 2 3 4 5 6 7 8 9) to represent numbers?
Denary
Also sometimes called “Base 10” or “decimal”
Use the placeholder values:
128 64 32 16 8 4 2 1
to conver the binary number 1010 to denary.
1010 in binary is the number 10 in denary.
There is a 1 under the 8 position and the 2 position.
Use the placeholder values:
128 64 32 16 8 4 2 1
to conver the binary number 1101 to denary.
1101 in binary is the number 13 in denary
8 + 4 + 1 = 13
Convert the denary number 28 into binary
00011100
16 + 8 + 4 = 28
Convert the binary number 00101001 into denary.
41 in denary
32 + 8 + 1
