The smaller one is a memory ...

... ignites the injected fuel without a spark. The diesel engine is a
compression-ignition engine. This article emphasizes the spark-ignition engine.
The invention and early development of internal-combustion engines are

Society is still being attacked by highly skilled computer criminals of which we know very little about them, their motives, and their tools of the trade. Therefore, to be effective in defense, we must understand how these attacks take place from a technical stand-point. To some degree, we must learn to become a computer criminal. Then we will be in a better position to defend agai ...

... expanded between the 1950s and the 1970s,
the focus of computer science broadened to include simplifying the use of
computers through programming languages—artificial languages used to
program computers, and operating systems—computer programs that provide a
useful interface between a computer and a user. During this time, computer
scientists were also experimenting with new applications and computer
designs, creating the first computer networks, and exploring relationships
between computation and thought.
In the 1970s, computer chip manufacturers began to mass-produce
microprocessors—th ...

... Simulated Emission
of Radiation) or LEDs (Light Emitting Diodes). Each of these methods create a
highly focused beam of light that is cycled on and off at very high speeds.
Computers at the transmitting end convert data or voice into "bits" of
information. The information is then sent through the fiber by the presence, or
lack, of light. So, all of the data is sent light pulses. Computers on the
receiving end convert the light back into data or voice, so it can be used.
All of this seems to be a very "modern" concept, and the technology we use
is. The concept though, was the idea of Alexande ...

facts, is required for the processing cycle to occur. Data is processed into
useful information by the computer hardware. Most computer systems consist of a
monitor, a system unit which contains the Central Processing Unit (CPU), a
floppy-disk drive, a CD-ROM drive, speakers, a keyboard, a mouse, and a printer.
Each component takes a part in one of the four operations. ...
