1. A thin client (sometimes also called a lean, zero or slim client) is a computer or a computer program that depends heavily on some other computer (its server) to fulfill its computational roles
2. Thin clients occur as components of a broader computer infrastructure, where many clients share their computations with the same server. As such, thin client infrastructures can be viewed as providing some computing service via several user interfaces. This is desirable in contexts where individual fat clients have much more functionality or power than the infrastructure requires.
3. A fat client  is a computer designed to take on these roles by itself. 
4. Total number of possible Binary Search Trees with n different keys = Catalan number Cn = (2n)!/(n+1)!*n!
5. A number is Fibonacci if and only if one or both of (5*n² + 4) or (5*n² – 4) is a perfect square.
6. Bi-endian processors can run in both modes little and big endian.
7. Intel based processors are little endians. ARM processors were little endians. Current generation ARM processors are bi-endian. Motorola 68K processors are big endians. PowerPC (by Motorola) and SPARK (by Sun) processors were big endian. Current version of these processors are bi-endians.
8. File formats which have 1 byte as a basic unit are independent of endianness e..g., ASCII files . Other file formats use some fixed endianness forrmat e.g, JPEG files are stored in big endian format.
9. Endianness matters in network programming: Suppose you write integers to file on a little endian machine and you transfer this file to a big endian machine. Unless there is little andian to big endian transformation, big endian machine will read the file in reverse order. You can find such a practical example here. Standard byte order for networks is big endian, also known as network byte order. Before transferring data on network, data is first converted to network byte order (big endian).
10. There are so many variants of Unix like Fedora Core , SUSE Linux etc. To standardize the Unix OS , IEEE has created a standard called Portable Operating System Interface(POSIX).
