describes microprocessor as a computer processor contained on an integrated-circuit chip.

Collegiate Webster dictionary

In the _______________, a microprocessor was defined as a central processing unit (CPU) realized on a _____________ chip, operating at a clock frequency of ____________ and constituting an __________ system.

mid-seventies LSI (large-scale integration) 1 to 5 MHz 8-bit

It was a single component having the ability to perform a wide variety of different functions.

Microprocessor

Many non-technical people associate microprocessors with only PCs yet there are thousands of appliances that have a microprocessor embedded in them telephone, dishwasher, microwave, clock radio, etc. In these items, the microprocessor acts primarily as a _____________ and may not be known to the user.

controller

The switching units in computers that were used in the early 1940s were the _______________.

mechanical relays

These were devices that opened and closed as they did the calculations

mechanical relays

Such mechanical relays were used in __________ of the 1930s

Zuse machines

Come the 1950s, and the ____________ took over.

vacuum tubes

The _________________________ used vacuum tubes as its switching units rather than relays

Atanasoff-Berry Computer (ABC)

True or False The switch from mechanical relay to vacuum tubes was an important technological advance as vacuum tubes could perform calculations considerably faster and more efficient than relay machines.

True

Then came the ___________ which was acknowledged as a revolutionary development.

transistors

In ____________, the authors describe the transistor as a device which was the result of a series of developments in the applications of physics.

"Fire in the Valley"

a device which was the result of a series of developments in the applications of physics.

transistors

The transistor changed the computer from a giant electronic brain to a commodity like a TV set. This innovation was awarded to three scientists:

John Bardeen, Walter Brattain, and William Shockley

True or False As a result of the technological breakthrough of transistors, the introduction of minicomputers of the 1960s and the personal computer revolution of the 1970s was made possible.

True

a device that could perform more complex tasks-a device that could integrate a number of transistors into a more complex circuit.

integrated circuits or ICs.

physically they were tiny chips of silicon, they came to be also referred to as chips.

Integrated Circuits / ICs

the demand for ICs was typically the _________ and __________ industries which were great users of computers and who were the only industries that could afford computers.

military and aerospace

an engineer at Intel, developed a sophisticated chip. This chip could extract data from its memory and interpret the data as an instruction. The term that evolved to describe such a device was "____________".

Marcian "Ted" Hoff Microprocessor

Therefore, the term "microprocessor" first came into use at Intel in _______

1972

A _______________ was nothing more than an extension of the arithmetic and logic IC chips corporating more functions into one chip.

microprocessor

the term still refers to an LSI single-chip processor capable of carrying out many of the basic operations of a digital computer

microprocessor

microprocessors of the late eighties and early nineties are full-scale _____-bit and _____-bit address systems, operating at clock cycles of ________

32 32 25 to 50 MHz

WHAT LED TO THE DEVELOPMENT OF MICROPROCESSORS?

Digital Computer Technology Semiconductors Calculator Industry

According to _______, a microprocessor executes a collection of machine instructions that tell the processor what to do.

Krutz

How a microprocessor works

According to Krutz, a Microprocessor executes a collection of machine instructions that tells the processor what to do. Based on the instructions, a Microprocessor does 3 basic things: 1. Using it's ALU, a Microprocessor can perform mathematical operations such as addition, subtraction, multiplication and division. 2. A microprocessor can move date from one memory location to another memory location. 3. A microprocessor can make a decision and jump to new set of instructions based on those decisions.
