Today’s Objectives
How are decimal numbers represented in binary format?
How is binary converted back to decimal format?
What is the format of an IPv4 address?WIIFM?

Binary and Decimal Format Decimal uses Base-10
numbering. Ten digits, in the range
of 0-9.
Binary uses Base-2 numbering.
Only two digits, 0 and 1.

Converting Decimal to Binary When converting from decimal to binary, place a
1 under each value that you need to add together to make the decimal number.
Use the chart from left to right.Example: What is 177 in binary?
Try this example on your own:1. 127

Converting Binary to DecimalTypically used in translating 8 bits ( 1 or 0) at a
time in IPv4 addresses, which we will discuss later.
All you do is plug those 8 bits into your chart, from left to right.
Add every value which has a 1 under it to get your decimal number.
Example: What is 10011100 in decimal?1 0 0 1 1 1 0 0
Try this example on your own:1. 10101010
