noise
bruit m

Noise. Noise is the cause of errors in data sent over a telephone wire. Random changes in voltage, frequency or phase may cause a change in the signal being sent, resulting in an incorrect code reaching the receiving end. This problem is largely overcome by using digital signals in transmission.

non - equivalence gate (NEQ)
circuit m de non éequivalence

Non-equivalence gate. A logic gate that operates with binary digits and is also known as an exclusive OR gate

Its output is logical 0 only when all of its inputs are identical. Note that in the inclusive OR gate, the output is logical 1 when any of its inputs has the logical value 1).

Exceptional OR gate

For example: The following truth table applies to the two-input disparity gate or exceptional OR gate:

This gate can be used to determine whether two binary numbers are the same or not. It can also be used to add two binary numbers but does not give the relay digit (i.e. when we add 1+1 in binary notation we get 10, where 1 is the relay digit and 0 is the sum).

NOR gate
circuit m NON - OU

The NOT - OR gate is the logical gate that operates with binary digits. Its output is 1 only when all of its inputs have a logical value, otherwise the output is 1.

Not - OR gate

For example: The following truth table applies to the two-input NOT - OR gate:

normalize
normaliser

calibrates. When working with floating point arithmetic, each number must be modified so that it has the required number of digits after the decimal point. The number is then said to be normalized.

NOT gate
circuit m NON

Not gate. A logic gate sometimes called an "inverter". The output is always the opposite of the input:

When combined with an AND gate or an OR gate, the output is reversed, giving a NOT gate, NAND gate, or NOR gate, respectively.

n - type
type - n m

N-type. The way a semiconductor such as silicon conducts electric current can be changed by adding a small amount of impurities. Some impurities, such as arsenic, increase the number of electrons (n ​​means more negative), giving n-type silicon. Transistors are made by combining n-type and p-type materials together.

number cruncher
ordinateur m powerful

A powerful computer. A name given to computers (usually mainframes) whose task is to perform large mathematical calculations.

numeric
numérique

Numeric A reference to numbers used in coding
denary notation The numbers from 0 to 9. The numerical keyboard has a touch for each number.
