The first single chip CPU was the Intel 4004 invented in Nov 1971‚ a 4-bit processor meant for a calculator. It processed data in 4 bits‚ but its instructions were 8 bits long. Program and data were separate. In 1972‚ Texax Instruments followed the Intel 4004/4040 closely with the 4-bit TMS 1000‚ which was the first microprocessor to include enough RAM‚ and space for a program ROM‚ to allow it to operate without multiple external support chips. It also featured an innovative feature to add custom

The focal point will be on the APS 5000‚ which is the APU for the Boeing 787 Dreamliner. This section is divided in two paragraph; APU in general (1.1.) and the APS 5000 (1.2.). 1.1. APU in general An aircraft APU is a small gas turbine specifically designed to meet the on-board demands of the aircraft when the Aircraft is On Ground (AOG). The APU drives both an electrical generator

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

This is copied off of howstuffworks.com i just needed something to get into an account.. sorry. In 2000‚ one of the biggest news stories was the rise of Napster and similar file-sharing programs. With these programs‚ you could get an MP3 version of just about any song you want without shelling out a dime. The record companies were fairly upset over this turn of events‚ and understandably so: They weren’t making any money off the distribution of their product to millions of people. An external

How do Bunsen Burners Work? Problems: How should a Bunsen burner be lit and adjusted to attain a blue flame? What is the hottest part of a Bunsen burner flame? Is burning the gas a chemical or physical change? Is it endothermic or exothermic? Hypothesis: The Bunsen burner should be lit by striking the match first‚ turning on the gas‚ igniting the gas‚ and adjusting the flame using the gas flow valve‚ the collar‚ and the table gas release to achieve a blue flame. I predict that the hottest part
