1's & 0's: Summary and the END

Since there is no time to "splain" let me sum-up. A computer stores information in on or off, zeros or ones. This is called binary as there are only two options. This means that numbers are stored in base-2. To store the letter “A” we go to the ASCII table and see that A is given a decimal value of “65” which is then stored in binary as 01000001.

When you get 2^10 characters together or 1024 characters it is known as a K or kilobyte of storage. In order the higher prefixes are Mega, Giga, Tera, Peta, Exa, Zetta, and Yotta. Today we have terabyte home disk drives available and a single yottabyte device is still theoretical.

Now, go amaze your friends with your new-found knowledge and amaze the salesperson at the electronics store by knowing that a terabyte is a thousand (1024) gigabytes!
