From Wikipedia, the free encyclopedia.
One hundred one (also One hundred and one) (101, CI) is the natural number following one hundred and preceding one hundred two. It is the 26th prime number and a palindromic number (therefore also a palindromic prime). The next prime is one hundred three, with which it comprises a twin prime. One hundred one is the sum of five consecutive primes (13 + 17 + 19 + 23 + 29). Given 101, the Mertens function returns 0.
101 is also:
- The atomic number of mendelevium, an actinide.
- The designation of US Highway 101, which runs from California to Washington.
- In universities, sometimes the course number of basic or entry-level courses. Also used in titles of books to indicate the book is meant for a beginner. At universities with four-digit course numbers, the equivalent course number is 1001 or 1010.

- The number of keys on a standard PC alphanumeric keyboard, including 12 or so function keys, cursor keys, and a numeric keypads and various other additions to the QWERTY typewriter keyboard.
- According to Books in Print, more books are now published with a title that begins with '101' than '100'. They usually describe or discuss a list of items, such as 101 ways to ... or 101 questions and answers about .... This marketing tool is used to imply that the customer is given a little extra information beyond books that include only 100 items. Some books have taken this marketing scheme even further with titles that begin with '102', '103', or '1001'.
