... to "programming" rules that the user must memorize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first Òdigital calculating machineÓ. It could only add numbers and they had to be entered by turning dials.

It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would nee ...
... files can quickly eat up the space on a hard drive and the administrator will need to keep an eye on these so that the system is not unduly slowed down by the system purging to make room for saved and working files. These deleted files can also be purged manually with the SALVAGE utility, which is a great way to make sure that a file you don't want others to see is completely removed from the system!!! For a user or administrator to retrieve a file using SALVAGE, the create right (right to edit and read a directory area or file) must be assigned to the directory in which the file resides. If the directory still exists, the files are put back into the directory ...
... and Jobs finish work on a preassembled computer circuit board. It has no Product keyboard, case, sound or graphics. They call it the Apple I. They form the Apple Computer Company on April Fool’s Day and sold the Apple I board for $666.66 at the Home brew Computer Club in Palo Alto, California.

According to Aley, "the most gratifying, and overdue, improvement is Windows 95's tolerance for file names in plain English" (29-30). Traditionally, users had to think of file names that summed up their work in eight letters or less. This was a constant problem because frequently a user would look at a list of files to retrieve and think "now what did I save that as?". Those days are over. Windows 95 will let the user save his or her work with names like "New Speech" or "Inventory Spreadsheet No. 1 ...

... of one (same goes for these as well). As the origin is not known as to whom may have made the invention and since may ancient empires used it, some of the first to use it were the Chinese and so the credit has been given to them. Another invention that comes from the abacus and was used in a similar fashion was the soraban. The soraban comes from the Japanese who perfected it to there use. The soraban is slightly different in the fact that it has one bead on the top part or each place value, and has only five beads in each place value on the bottom part.

... dead. At last count, this scenario has happened 31 times. How many more times does it have to happen before the automotive industry does something about it?

... numbers, and other private data are flying through phone lines near your house. The downside to this technological marvel that we all use, whether we know it or not, is that thieves, disgruntled network administrators, and other unsavory characters can make an easy living off of the Internet, maybe even stealing from you. How? It's all in a day's work for them. One Russian hacker spent a few years bleeding money from the Citibank corporation here in the states from his cozy little house in Russia. His labor was rewarded with $10.4 million dollars in several bank accounts around the world. Unfortunately for him, his labor was also rewarded with arrest. (Cary ...
