Which of these are correctly formatted Python dictionaries? Check all that apply. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’
Advocard [28]

Answer:

A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}

Explanation:

Since <em>python does not use type when declaring a variable</em>, you must make sure you make your variables correctly or else it won't compile correctly. Lists use braces[]; Strings use quotes, "" or ''; Integers are just declared with a number(s); Dictionaries use brackets{} and inside are <u>attributes of something</u>. For instance, you can use dictionaries to describe ages, {'"Bryan": 6, "Alex": 13, etc.} <u>Sort of like a json file</u>. Dictionaries also tend to use <u>uppercase letters</u> when describing something. The only answer that has all the attributes correct is A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}

hope i helped :D

Consider the following code snippet:public static void main(String[] args) throws FileNotFoundExceptionWhich of the following st
iVinArrow [24]

Answer:

The main method should simply terminate if the FileNotFoundException occurs.

Explanation:

Considering the full code snippet

snippet:public static void main(String[] args) throws FileNotFoundException

public static void main(String[])

represent the entry point method to a java main method

The addition of

throws FileNotFoundException

widens the scope of the main method to explicitly specifies that an exception named the FileNotFoundException may be thrown.

So, if any part of the code explicitly throws the FileNotFoundException the compiler makes use of this to throw an exception.

By throwing an exception, the main method is not catching any exceptions, instead it handles the FileNotFoundException by throwing it to the source which invoked the main method

This is required by the compiler to terminate the program if the FileNotFoundException occurs.

What are the types of Operating System​
Archy [21]

Answer:

1. Gestión de la memoria principal

Esta es una característica del sistema operativo básica. La memoria principal de la computadora almacena los datos que serán usados por el CPU en la ejecución de los programas. El sistema operativo se encarga de gestionarla, es decir, asignar partes de memoria a la nueva información usada, y evitar que se sature.

2. Gestión de la memoria secundaria

Es la memoria más “permanente” de una computadora. Al igual que la memoria principal, el SO sistema operativo asigna el orden de guardado en esta memoria y la mejor manera de aprovechar el espacio libre.  

3. Gestión de procesos

Cuando envías un comando para que el ordenador realice una tarea, una de las funciones del sistema operativo es organizar los recursos de la computadora para ejecutarla. Esto incluye la memoria, el tiempo del CPU, los programas y archivos necesarios para ejecutar la tarea, los procesos que podrían entorpecerla y los periféricos que podrían ser necesarios para cumplirla.

4. Gestión de recursos  

¡Esta es una de las características del sistema operativo más importantes! El sistema operativo coordina los recursos del hardware que integra la computadora para cumplir con las tareas requeridas. El CPU, los periféricos, las memorias principal y secundaria, los programas, todo tiene que trabajar al unísono para cumplir con las tareas de forma óptima.

5. Gestión de usuarios  

El software operativo controla el acceso de los usuarios a las cuentas individuales o grupales. También, se encarga de administrar a qué recursos e información tiene acceso cada uno de ellos.  

6. Gestión de la seguridad  

Así como controla el acceso de usuarios, el sistema operativo también está encargado de gestionar los controles de seguridad de la computadora, entre ellos el firewall. Por ejemplo, en cuanto a la función del sistema operativo para la seguridad informática es evitar la pérdida de datos, controlar la confidencialidad de los datos y controlar el acceso a la información y a los recursos del equipo.
