Existing RFIDs have a communication distance of about 5 meters, but printed RFIDs are limited to about 1 meter. They can store about 60 bits of data. Photograph: Courtesy of Toray Now remember, 60 bits can store about 1 quintillion digits. That means we could tag every product in the ...
The number above has 64 digits. As you probably noticed, that number consists not just of numbers but also letters. Why is that? The decimal system uses factors of 100 as its base (e.g., 1% = 0.01). This, in turn, means that every digit of a multi-digit number has 100 possibiliti...
For imprecise amounts of one million or more, you’ll often see letters used in place of the digits. This is especially true in newspaper headlines and in graphics used in news broadcasts. M is used for million; B is used for billion. These are the two you’ll see most often. Someti...
SET QUOTED_IDENTIFIER ON SET ANSI_NULLS ON SET NOCOUNT ON GO CREATE FUNCTION dbo.udf_Num_ToWords ( @Number Numeric (38, 0) -- Input number with as many as 18 digits ) RETURNS VARCHAR(8000) /* * Converts a integer number as large as 34 digits into the * equivalent words. The f...
To avoid confusion between systems that use decimal points in place of decimal commas, we will put a space between sets of 3 digits. To avoid confusion, the number 123456789246801357 will be written as: 123 456 789 246 801 357 Using the system described thus far, we are now able to con...
Introduction Big data is a term that refers to an enormous volume of structured and unstructured digital data extracted from various sources [1]. According to IBM, approximately 2.5 quintillion bytes of data are generated every day [2]. Moreover, 90% of the data we have today were created ...
That bit after “watch?v=” is an 11 digit string. The first ten digits can be a-z,A-Z,0-9 and _-. The last digit is special, and can only be one of 16 values. Turns out there are 2^64 possible YouTube addresses, an enormous number: 18.4 quintillion. There are lots of You...
(300+ digits). Given only N, finding q and p would require vast amount of guessing and checking, but knowing q beforehand allows you to find p with simple division. This factorizationtrap dooris what enables the RSA algorithm. The public key / private key algorithm used in Bitcoin is ...
Before we examine binary, it helps to consider the numeral system that the modern world uses. Decimal, or base 10, is a system where each possible place in a number can be one of 10 digits. To express a single-digit number in decimal, we use the numerals 0 through 9. To go higher...
Without a doubt, one of the more common technology-related questions we get asked about surround those data storage metrics, liketerabytes,gigabytes,petabytes,megabytes, etc. You've probably heard most of the terms before, but do you know what they mean? How many gigabytes are in a terabyte?
