Answer:
Un problema con las matrices dinámicas es que una vez que se crea la matriz utilizando el nuevo operador, no se puede cambiar el tamaño. Por ejemplo, es posible que desee agregar o eliminar entradas de la matriz de manera similar al comportamiento de un vector. Este proyecto le pide que cree una clase llamada DynamicStringArray que incluye funciones miembro que le permiten emular el comportamiento de un vector de cadenas.
La clase debe tener:
Una variable miembro privada llamada dynamicArray que hace referencia a una matriz dinámica de tipo cadena.
Una variable de miembro privada llamada tamaño que contiene el número de entradas en la matriz.
Un constructor predeterminado que establece la matriz dinámica en NULL y establece el tamaño en 0.
Una función que devuelve el tamaño.
Una función llamada addEntry que toma una cadena como entrada. La función debe crear una nueva matriz dinámica un elemento más grande que dynamicArray, copiar todos los elementos de dynamicArray en la nueva matriz, agregar la nueva cadena al final de la nueva matriz, incrementar el tamaño, eliminar el antiguo dynamicArray y luego establecer dynamicArray en el nueva matriz.
Una función llamada deleteEntry que toma una cadena como entrada. La función debe buscar la cadena en dynamicArray. Si no lo encuentra, devuelva falso. Si lo encuentra, cree una nueva matriz dinámica con un elemento más pequeño que dynamicArray. Copie todos los elementos excepto la cadena de entrada en la nueva matriz, elimine DynamicArray, reduzca el tamaño y devuelva verdadero.
Una función llamada getEntry que toma un número entero como entrada y devuelve la cadena en ese índice en dynamicArray. Devuelve la cadena "" si el índice está fuera de los límites de dynamicArray.
Sobrecargue el operador [] para que pueda obtener y cambiar un elemento por un índice entero. Si el índice está fuera de los límites, devuelve una cadena "".
Un constructor de copia que hace una copia de la matriz dinámica del objeto de entrada.
Sobrecargue el operador de asignación para que la matriz dinámica se copie correctamente en el objeto de destino.
Un destructor que libera la memoria asignada a la matriz dinámica.
Cree un programa de prueba adecuado para evaluar su clase.
Debería nombrar el proyecto ASG10. Al comprimir la carpeta del proyecto, ASG10, incluya todos los archivos (.sln, .cpp, etc.) y subdirectorios (Debug, etc.).
************************************************
Copie su DynamicStringArray de la Tarea 10. Corrija el programa para que las 13 pruebas funcionen correctamente. Modifique la definición del operador sobrecargado [] y getEntry para que generen una excepción OutOfRange si se usa un índice que está fuera de rango. OutOfRange es una clase de excepción que define. La clase de excepción debe tener un miembro int privado y un miembro string privado, y un constructor público que tenga argumentos int y string. El valor del índice infractor junto con un mensaje deben almacenarse en el objeto de excepción. Tú eliges el mensaje para describir la situación. Modifique su programa de prueba y agregue pruebas que detecten la nueva clase de excepción.

True or False: One benefit of virtualization is that it allows for better use of already existing hardware that may not be seeing full utilization.
Answer:
True.
Explanation:
Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.
Generally, to use the virtualization technology on a computer, it must be enabled in the BIOS/UEFI).
Additionally, VMware tools can be installed on host computers to check which processes are having high CPU usage by using vimtop, as well as checking if vCenter Server is swapping.
Hence, one benefit of virtualization is that it allows for better use of already existing hardware that may not be seeing full utilization. Hardware components such as storage devices, central processing unit (CPU), random access memory (RAM), host computers are extensively put into use.
Write a python program that: - Defines a tuple of 5 integer numbers - prints the tuple - Appends a new value to the end of the tuple - prints the tuple again Please note that appending a new value to a tuple will change the tuple. However, as you learned in Unit 5, tuples are immutable i.e. do not change. Therefore, to solve this problem, you need to find a way to change a tuple.
Answer:
The program is as follows:
my_tuple = (1,2,3,4,5)
print(my_tuple)
mylist = list(my_tuple)
mylist.append(6)
my_tuple = tuple(mylist)
print(my_tuple)
Explanation:
This defines a tuple of 5 integers
my_tuple = (1,2,3,4,5)
This prints the tuple
print(my_tuple)
To add new element to the tuple; First, we convert it to list. This is done below
mylist = list(my_tuple)
Then, an item is appended to the list
mylist.append(6)
The list is then converted to tuple
my_tuple = tuple(mylist)
This prints the tuple
print(my_tuple)

1. When the Cisco 2950 switch is first turned on, it behaves like a hub. Why is this so, and what must happen before the switch can send unicast traffic to a specific port
Answer:
The switch sends broadcast traffic to all ports like a hub to get the number of ports used and build its MAC address table.
Explanation:
A network switch is a device used in a LAN to connect all available workstations. Unlike a network hub, it is able to send frames from a host or workstation to another using its MAC address table.
An example of a switch is the Cisco 2950 switch. When it is first turned on, it acts as a hub, broadcasting traffic to all its ports. This process is used to create a MAC address table to get the IP address of workstations and the ports they relate to, enabling it to send unicast traffic to a specific port.
What is true about the process of converting analog data into digital data?
a
To make the digital version be a more accurate representation of the analog data, the process should use fewer bits to represent each sample.
b
The digital version is a representation of the analog data but cannot include all of the details.
c
A longer interval between measured samples means more details will be captured in the conversion from analog to digital
d
The digital version contains all of the details of the analog data, as long as enough storage capacity is available.
Answer:
b. The digital version is a representation of the analog data but cannot include all of the details.
Explanation:
Analog data are continuous infinite stream of data but since the computer has finite memory, these data could only be represented on the computer by converting them to finite data. This process is called analog to digital conversion.
The following are some of the things that should be noted when doing this conversion:
1. Since the digital version is a finite representation of the analog which is infinite, it (the digital version) cannot include all of the details in the analog.
2. For the digital version to be a more accurate version of the analog data it represents, as much bit as possible should be used to represent each sample.
3. Short intervals between measured samples means more details will be captured in the conversion from analog to digital.
Analog to digital conversion of data simply involves the converting an infinite stream of data into a Finite version of the same data.
Digital data are Finite representation of the infinite data typical of analog representation. Hence, a Finite sequence, will not habor all the data or information contained in an analog record.
Therefore, the digital data representation will only be a Finite representation of the analog data and will not contain all of the details.

Which statement best describes the refraction of light
Answer:
Two wave pulses move toward each other along a rope. The two waves produced have different speeds.
Explanation:
Refraction of light is the change in the speed of light as it travels. The correct option is C.
What is refraction?The bending of light as it passes from one medium to another is caused by the difference in the speed of light in the different media.
When viewed through a medium with a different refractive index, this bending of light can cause objects to appear distorted or displaced.
The change in direction and speed of light as it passes from one medium to another, such as from air to water or from water to glass, is referred to as refraction.
This happens because the speed of light changes when it moves from one medium to another due to a change in the refractive index of the medium.
Thus, the correct option is C.

In a systems development life cycle (SDLC) model, the purpose of the _____ is to create a physical model that will satisfy all documented requirements for the system.
Answer:
systems design phase.
Explanation:
In a systems development life cycle (SDLC) model, the purpose of the systems design phase is to create a physical model that will satisfy all documented requirements for the system.
This ultimately implies that, that system design involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.
The system inputs and outputs will be designed along with a plan of the way the system's features will be navigated.
Basically, system design is divided into two groups;
I. Logical design.
II. Physical design.
The design of service systems is the process involved in planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients. A characteristic that can be used to guide the design of service systems is to ensure services cannot be inventoried.
