3 0

Explanation:

  • A connector is the unique end of a plug, jack, or the edge of a card that connects into a port. Port: The port has either holes or a slot that matches the plug or card being connected into the port. For example: cables are plugged into Ethernet ports, and cables and flash drives are plugged into USB ports.

Write the code to produce a for loop that counts down from 20 to 0 by 2’s and prints the number each time it goes through the lo
yulyashka [42]

Explanation:

Count-controlled for loop (Three-expression for loop)

This is by far the most common type. This statement is the one used by C. The header of this kind of for loop consists of a three-parameter loop control expression. Generally it has the form:

for (A; Z; I)

A is the initialisation part, Z determines a termination expression and I is the counting expression, where the loop variable is incremented or dcremented. An example of this kind of loop is the for-loop of the programming language C:

for (i=0; i <= n; i++)

This kind of for loop is not implemented in Python!

Numeric Ranges

This kind of for loop is a simplification of the previous kind. It's a counting or enumerating loop. Starting with a start value and counting up to an end value, like for i = 1 to 100

Python doesn't use this either.

Vectorized for loops

They behave as if all iterations are executed in parallel. This means, for example, that all expressions on the right side of assignment statements get evaluated before the assignments.

Iterator-based for loop

Finally, we come to the one used by Python. This kind of a for loop iterates over an enumeration of a set of items. It is usually characterized by the use of an implicit or explicit iterator. In each iteration step a loop variable is set to a value in a sequence or other data collection. This kind of for loop is known in most Unix and Linux shells and it is the one which is implemented in Python.

Example of a simple for loop in Python:

>>> languages = ["C", "C++", "Perl", "Python"]  

>>> for x in languages:

...     print(x)

...  

C

C++

Perl

Python

¿Cuales son los dos estados de una computadora y que significa cada uno?
hjlf

Answer:

En ciencias de la computación, el estado de un circuito lógico digital o programa de computadora es un término técnico para toda la información almacenada a la que un circuito o programa tiene acceso en un momento dado. La información recibida previamente en las entradas se almacena en la memoria de elementos electrónicos, como disparadores, celdas de memoria. El contenido almacenado de estos elementos de memoria, en un momento dado, denominado colectivamente el "estado" del circuito, contiene toda la información sobre el pasado al que tiene acceso el dispositivo. Así, básicamente, una computadora puede tener acceso a dicho estado o no, según se encuentre encendida o apagada.

When data is being prepared for transmission onto the network, it is broken into small pieces and a header and trailer are added
Archy [21]

Answer:

The correct answer to the following question will be "Encapsulation".

Explanation:

  • Encapsulation relates to the pooling of data with techniques used by the database or the limitation of immediate access to many of the elements of the entity.
  • As data is being processed for transfer to the network, it's split into tiny pieces and a trailer and header are attached to each piece to help determine it.
  • It is a method of shielding data facts and preserving the object's data and actions from abuse by certain objects.

Therefore, Encapsulation is the right answer.

The elements of an integer-valued array can be initialized so that a[i] == i in a recursive fashion as follows: An array of size
blondinia [14]

Answer:

public static void init(int[] arr, int n) {

    if (n==0)

        arr[0] = 0;

    else {

        arr[n-1] = n - 1;

        init(arr, n-1);

    }

}

Explanation:

Create a method called init that takes two parameters, an array and the number of elements in the array

When n reaches 0, set the first element to 0 (This is a base for our recursive method)

Otherwise, set the element in index i to i

Call the init inside the init, this is the recursion part, with same array but decrease the number of elements by 1 (We decrease the number of element by 1 in each time so that it goes through all the elements in the array)
