NAND gate
circuit m NON - ET

Not - and gate. It is the logical NOT AND gate whose truth table has two inputs as follows:

Not - and gate

It is worth noting that by combining the two inputs together in a NOT gate, this becomes a NOT gate or its inverse.

Napier
Napier

Napier. John Napier (1550 - 1617) John Napier is a Scottish mathematician who invented a very simple device for performing multiplication operations known as "Napier's rods". This device consists of a set of eleven rods distributed in numbered sections when placed side by side, enabling multiplication by a single number. Thus, multiplying 634 by 58 gives the result by multiplying the number by 50 times) and by (8 times) and adding the two results. Napier was also a pioneer of decimal notation, but his fame is mainly due to the fact that he was the person who invented logarithms, which made it possible to perform complex multiplication and division operations easily. This innovation led to the emergence of the slide rule and simple calculators that paved the way for the development of modern computers.

NCC

National Computing Centre. Abbreviation for National Computing Centre in Britain.

negation
négation f

Negation. The process of changing something into its opposite. The negation of the binary number 101 is 010 and every binary digit changes to its opposite. Negation plus one allows one to find the two's complement of a binary number. The advantage of this is that we can use the normal rules of addition and subtraction with negative numbers. For example:

negation + 1 (two's complement)
negation (one's complement)
number

The third column here is the two's complement of the first column. In the positive and negative binary number system, the leftmost bit is used to specify the sign, 0 for positive and 1 for negative.

However, in the case of 1, only the first bit is negative (place values ​​1+, 2+, 4+, 8-), so the last row of the table above tells us that .
- 6 (from 8- +2) is the two's complement of +6 (+4+2).

NEQ

Abbreviation for non-equivalence gate.

network
réseau m

A network. Several computers are connected to each other to share printers, disk drives, and other peripheral devices. Data can be sent at high speeds, and each user can have access to all the facilities. Networks have specialized operating systems to control the flow of data, create queues for peripheral devices, and provide passwords and security features to users. Networks are often called distributed processing systems. A network of computers connected to each other within a building or enclosed space is called a "local area network". When users are far from central facilities and access the Internet via a modem, this is called a "wide area network".

NLQ

Near letter quality.

Abbreviation for near letter quality,

See dot matrix printer.
