...Term Paper: History of Intel and its microprocessors The microprocessor is a chip made of silicon that holds a central processing unit. Both the term’s central processing unit or CPU and microprocessor can be used and mean the same thing. The human brain has been compared to a microprocessor. Microprocessors are ultra fast calculators and what makes a microprocessor appear intelligent is the speed at which it can process data. The electronics industry names, microprocessors first by makers name and then model family name or number. A recent example, are the Intel Core i7 and AMD FX 8 Core Black Edition. Microprocessors provides scientist, engineers, architects, graphic designers, researchers, and other professionals with the processing power users to perform all the many functions needed to do their jobs and make new discoveries and explore what before could not have been even imagined. The history of microprocessors will be covered; this includes the history of Intel Corporation, important highlights in the development of the microprocessor. All digital computers use electronic switches. These switches represent binary digits or bits. The first computers used vacuum tubes as switches to represent on-or-off binary data, but vacuum tubes had many problems. Without the invention of the transistor, microprocessors and the modern computer would not be possible. Bell Laboratory engineers John Bardeen and Walter Brattain invented the transistor in 1947 (transistor). Transistors...

Then he joined the creative classes at the school and spent 18 months. In 1974, Jobs worked for Atari as a video game designer (Biography). Apple Inc. was founded on April 1, 1976, in Job’s Garage by two extremely innovative and intelligent minds Steve Jobs and Stephen Wozniak. Their entrepreneurial venture was funded by selling Volkswagen Bus belongs to Jobs and a scientific calculator belongs to Wozniak (Biography). For spiritual enlightenment, Jobs visited India and then came back to California in the fall. A job was interested in starting his new venture and he convinced Wozniak to become his partner by seeing the hobby as well as innovativeness of Wozniak of manufacturing microcomputers that were cheaper. Apple I was the first computer manufactured in Jobs’ Garage in May 1976.

...technology" redirects here. For the company, see Computer Technology Limited. A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out. A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment. The first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information...
