Adder

A circuit that adds two binary numbers together.

Back to Top

Address

A location information is stored in either memory or storage.  This is usually a number indicating row and column.

Ampere (A)

This is the measurement of current flowing throw a circuit.

ASCII

This is pronounced (Ask-EE).  This is a stander 7-bit variable for transferring characters, letters and numbers between digital circuits.

Back to Top

Binary

The very basic langue of a circuit.  1 represents a circuit on and 0 represents a circuit off.

Back to Top

Boolean Logic

Boolean Logic was the invention of a mathematician of the name Bool. Boolean Logic t uses 1, 0,AND, OR, and NOT to represent mathematical decisions.

Capacitor (C)

A store house for electrical charge.  This device is basically tow metal plates a very small distends apart.

Back to Top

Current

Current is the rate at witch electrons flow throw a circuit.  Picture a circuit as a river, we could have a raging river or a little trickling stream. This is the driving force of the circuit and it is measured in amperes or amps.  To find the amount of current in a circuit us this formula.

I = average currents in amps.  

/\q = the change in  current "coulombs".  

/\t = change in time

Digital

A representation of  a 1 for high and 0 for low.

Back to Top

Input/Output (I/O)

I/Os are any way the electronic circuit gets and send information to the outside world.  In your computer's case an input would be the keyboard and an output would be the monitor.

Back to Top

Operating System (OS)

This is a program that handle all of the 

Back to Top

Processor

The work hoarse of any computer.  This device does all the math operations of a system.

Back to Top

Random Access Memory (RAM)

A sort term storage for information that will be deleted if power is remove form it.  This type does not need to be accessed in a sequence, thus it can be randomly accessed.

Back to Top

Resistance

Resistance limits the current flow throw a circuit.  This is like rocks in a river, they will slow down the current but will not stop it.  Different materials have different resistive property's and the person to discover this was George Simon Ohm.  The unit of measurement he invented is called ohms, witch is represented with .

R = resistance in "ohms"

l  = length in feet

A = cross-sectional are in circular mils

p = the resistively of the material

Back to Top

Storage

This device can hold information even after the power is removed.  This is often a hard drive, EEPROM, EPROM, etc.
