As you will be aware, the binary number system has a base of 2, meaning that all numbers can be represented using the necessary combination of only 2 digits (0 & 1).
For this reason, all computers (in fact all electronics) use binary. This is because all electronics work on the fundamental principle of either setting something (or many things) as ONor setting it as OFF. There are two alternatives. We can use 0 & 1 to represent this. Binary is the most logical way for us to translate something physical like flicking a switch/pressing a button/magnetising a sector on a computer's hard disk etc. into data. All data on your computer is thus stored as a combination of 0's and 1's.
Clearly without computers and electronics society would be extremely different than it is today, so you can see that we rely on it hugely.

What decimal number is equivalent to binary number 121?
That's not a binary number ! Binary numbers can only use the digits 1 and 0.
Could the binary number 1000 be a binary coded decimal?
It's 8. (Next time you can use calc.exe of your windows.)
What is the name of the system of zeros and ones that computers use to communicate?
Binary System
What is the sum of the binary numbers?
The sum of binary numbers is also a binary number.
What are the two numbers the binary system uses?
In theory any two symbols would do, but usually they are 1 and 0.So, for example, the binary for three is 11, and for thirteen the binary is 1101.To make conversions, use the calculator that comes with a Windows operating system. Set the View to Scientific, make sure the Dec (for decimal) button is selected, and key in a number. Then selected the Bin (binary) button, and the binary equivalent displays.
