On the elctronic googs the words "CE are generally

I find the words "CE" on almost all the electronic goods like computers,calculators,cell phones etc.what is their importance?What is the exact meaning of that?

The LAST prize--aka the BOOBY prize!

I hope I win...I worked so hard on this problem, and I want to thank all the little people who helped me to answer this problem (correctly or not): Mom and Dad (for giving me some good brains and made sure I learned all those silly mathematics tables!), God (who's not really a person anyway) who just gave me good brains!, and whoever invented calculators!

computing

the calculators were the basic computers. I think that the idea of the computers came from this device only.....

How often do you use calculators?

Computers

A computer is a machine for manipulating data according to a list of instructions. Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers.Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.

The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capacity is not considerations

Tetris

Tetris is a very popular computer puzzle game. It was originally designed and programmed by Alexey Pazhitnov (last name transliterated Pajitnov by The Tetris Company ) in 1985, while he was working for the Dorodnicyn Computing Centre of the Russian Academy of Sciences in Moscow, during the days of the Soviet Union. Pajitnov has cited pentominoes as a source of inspiration for the game. Its name is derived from the Greek numerical prefix "tetra-" meaning four, as all of the blocks are made up of four segments. The game (or one of its many variants) is available for nearly every video game console and computer operating system, as well as on devices such as graphing calculators, mobile phones, and PDAs. Tetris has even appeared as part of an art exhibition on the side of Brown University's 14-story Sciences Library. The game first gained mainstream exposure and popularity beginning in 1989 when Nintendo released Tetris on its Game Boy system. Tetris consistently appears on lists of the greatest video games of all time. A random sequence of tetrominoes (sometimes called "tetrads" in older versions) - shapes composed of four square blocks each - fall down the playing field. The object of the game is to manipulate these tetrominoes with the aim of creating a horizontal line of blocks without gaps. When such a line is created, it disappears, and the blocks above (if any) fall. As the game progresses, the tetrominoes fall faster, and the game ends when the player "tops out", that is, when the stack of tetrominoes reaches the top of the playing field and no new tetrominoes are able to enter. (The exact definition of a top-out varies from version to version.) The seven one-sided tetrominoes in Tetris are referred to as I, J, L, O, S, T, and Z. All are capable of single and double clears. I, J, and L are able to clear triples. Only the I tetromino has the capacity to clear four lines simultaneously, and this clear is referred to as a "tetris." (This may vary depending on the rotation and compensation rules of each specific Tetris implementation. For instance, in the Tetris Worlds type rules (see below) used in many recent implementations, certain rare situations allow T, S and Z to 'snap' into tight spots, clearing triples.)

Computer

The end of the Middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers. It is known as "Computer" now.
