In 1994, Intel released a microprocessor that had a major flaw that they dismissed as simple and not likely to replicate very often while in use. The Pentium microprocessor, used in both the 486DX and Pentium CPUs both included a floating point unit, also known as a math coprocessor, which was used to help spreadsheet users. Floating point units used non-integers in their arithmetic methods instead of integers, much like the previous CPUs. FPUs made the arithmetic must faster and allowed for more

The Role of Computers in Our Future As far as computers in the future, I feel that they are going to play a major role. They will be in everyday life, in everything we do. There will be many areas affected by the wide use of computers. Areas such as: home, work, schools, automobiles, electronics, and humans. Although these areas are already affected, they will be even more as we move into the future. To begin this discussion I will show you the effects on the work place and humans. As

environment scan revealed some very interesting facts. The first and most important was that design engineers were in incredibly short supply. There was adequate mask-making and manufacturing capacity for making ingots and imprinting integrated circuits. There were packing issues which consisted of at least two sub issues, industry capacity and packaging technology. The issue of testing of the packaged semiconductor devices had to do with the relative value of a semiconductor to the various

including but not limited to the following: A manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors, and, in addition, no pole can be operated independently; a line valve; a block; and any similar device used to block or isolate energy. Push buttons, selector switches and other control circuit type devices are not energy isolating devices. Lockout. The placement of

Name: Delcil Charles Program: Architecture/ Building Construction Course: Information Technology Date: 04/02/11 A Brief History of the computer. The history of computers starts out about 2000 years ago, at the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around, according to programming rules memorized by the user, all regular arithmetic problems can be done. Another important invention around

Introduction A microcontroller will be used in the development of the experiment which is basically a computer on a chip. It is a type of microprocessor emphasizing self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor. In addition to all arithmetic and logic elements of a general purpose microprocessor, the microcontroller usually also integrates additional elements such as read-only and read-write memory, and input/output interfaces. Microcontrollers are frequently

ROM Data on floppy disk RAM - As a computer processes data and instructions, it temporarily stores information internally, usually on silicon random-access memory, or RAM, chips--often called semiconductor memory. Usually mounted on the main circuit board inside the computer or on peripheral cards that plug into the board, each RAM chip may consist of as many as 16 million switches, called flip-flop switches that respond to changes in electric current. Each switch can hold one bit of data: high

Breanna McCarthy NT 1110 comp. strategies & logic Unit 5 Analysis 1 Pentium Flaw Nature of Pentium flaw: Engineers discovered a flaw in the microprocessor in the floating point math subsection. This would cause low order bits to be incorrect. This could quickly lead to larger errors in calculations When and how it was discovered: This flaw was discovered in 1994. Apparently Intel engineers found it but decided to keep it quiet until a professor, Dr. Thomas Nicely, discovered it and
