Most Expensive Computer Mouse

Most consumers just use the mouse that comes with their desktop and only purchase a mouse when they spill the inevitable hot cup of coffee and ruin the wheel action on their mouse and their mousepad.

Others must think of their mouse as a fashion accessory though, because why else would Swiss manufacturer Pat Says Now produce the world’s most expensive computer mouse.
The costly peripheral is cast from 18 carat white gold and set with 59 brilliant cut diamonds, and will only set you back £12,400 ($24,180 USD). The most expensive mouse utilizes a modern 3-button wheel optical mouse design, options for USB or PS/2 connections for either PC or Mac, a 800 dpi Resolution, and a 3 year warranty.
The expensive mouse comes in two designs, “Diamond Flower” and the “Scattered Diamond” layout. You can bling out and personalize the most expensive computer mouse by adding your initials in diamonds, and can choose from yellow, red or white gold with white or black trim.

Most Expensive Computer in the World

The Japanese government estimates the Earth Simulator cost $400,000,000, making it the most expensive computer ever built. The budget for the Earth Simulator project was authorized for the National Space Development Agency of Japan (NASDA) and the Power Reactor and Nuclear Fuel Development Corporation (PNC) in 1997, and NEC Corporation made the winning bid for the Japanese project.
By May 2002, the 640 processor node supercomputer was benchmarked with Linpack as having 35.86 TFlop/s performance. This gave it the top spot on the TOP500 Supercomputer Sites list until 2004 when IBM’s BlueGene/L supercomputer took its place using an architecture that cost less than half as much to implement.
Each processor node in the Earth Simulator contains 8 vector processors running at 500MHz with 16GB of shared memory, and the total main memory in the machine is 10 terabytes. The operating system running on the supercomputer is NEC’s UNIX-based OS called “SUPER-UX” which is used on NEC’s SX Series of supercomputers.
This expensive computer is used for a wide variety of international projects, most of which are related to atmospheric, climate, and oceanographic simulation.

Define Linux

LinuxLinux (often pronounced LIH-nuhks with a short "i") is a Unix-like operating system that was designed to provide personal computer users a free or very low-cost operating system comparable to traditional and usually more expensive Unix systems. Linux has a reputation as a very efficient and fast-performing system. Linux's kernel (the central part of the operating system) was developed by Linus Torvalds at the University of Helsinki in Finland. To complete the operating system, Torvalds and other team members made use of system components developed by members of the Free Software Foundation for the GNU Project.
Linux is a remarkably complete operating system, including a graphical user interface, an X Window System, TCP/IP, the Emacs editor, and other components usually found in a comprehensive Unix system. Although copyrights are held by various creators of Linux's components, Linux is distributed using the Free Software Foundation's copyleft stipulations that mean any modified version that is redistributed must in turn be freely available.
Unlike Windows and other proprietary systems, Linux is publicly open and extendible by contributors. Because it conforms to the Portable Operating System Interface standard user and programming interfaces, developers can write programs that can be ported to other operating systems. Linux comes in versions for all the major microprocessor platforms including the Intel, PowerPC, Sparc, and Alpha platforms. It's also available on IBM's S/390. Linux is distributed commercially by a number of companies. A magazine, Linux Journal, is published as well as a number of books and pocket references.
Linux is sometimes suggested as a possible publicly-developed alternative to the desktop predominance of Microsoft Windows. Although Linux is popular among users already familiar with Unix, it remains far behind Windows in numbers of users. However, its use in the business enterprise is growing.
Linux is a contraction for Linus' Unix; the short i sound preferred by most (including Torvalds) derives from the Swedish pronunciation of Linus.
