Answer:
Referential integrity, is the condition with the rule that foreign key values are always valid, and it is founded on entity integrity. Entity integrity, makes certain, the condition that there is a unique non-null primary key for every entity. The parent key functions as the source of the unique identifier for a set of relationships of an entity in the referential constraint parent table, and defining the parent key is known as entity integrity

¿Si tengo un disco de 1Tb, y en el tengo almacenado lo siguiente:
a) 300 videos de 126GB en total
b) 1376 archivos de office que cada uno pesa 117kb.
c) 3000 mp3 de 3.8mb cada uno.
d) 4Gb ocupados en el sistema operativo.
¿Cuánto espacio me sobre en el disco duro?
Answer:
Espacio a la izquierda = 858,8439008 Gb
Explanation:
Dados los siguientes datos;
Tamaño del disco duro = 1 Tb
Vídeos = 126 Gb
Archivos de Office = 1376 * 117 Kb = 160992 Kb
Mp3 = 3000 * 3.8 mb = 11400 Mb
Sistema operativo (OS) = 4 Gb
Conversión:
En primer lugar, convertiríamos el tamaño del archivo en kilobytes a megabytes.
1000 Kb = 1 Mb
160992 Kb = 160992/1000 = 160.992 Mb
Memoria total (Mb) = 11400 + 160,992
Memoria total (Mb) = 11560.992 Mb
A continuación, convertiríamos el tamaño del archivo en megabytes a gigabytes;
1000 Mb = 1 Gb
11560.992 Mb = 11560.992/1000 = 11.560992 Gb
Por último, sumaríamos todos los tamaños de archivo en gigabytes;
Espacio total (memoria) utilizado = 126 + 11.560992 + 4
Espacio total (memoria) utilizado = 141,560992 Gb
Conversión:
1000 Gb = 1 Tb
Espacio restante = tamaño del disco duro - memoria total utilizada
Espacio a la izquierda = 1000 - 141.560992
Espacio a la izquierda = 858,8439008 Gb

Write a python application that allows a user to enter any number of student test scores until the user enters 999. If the score entered is less than 0 or more than 100, display an appropriate message and do not use the score. After all the scores have been entered, display the number of scores entered and the arithmetic average.
Answer:
This program is as follows
total = 0; count = 0
testscore = int(input("Score: "))
while testscore != 999:
if testscore < 0 or testscore > 100:
print("Out of range")
else:
total+=testscore
count+=1
testscore= int(input("Score: "))
print(count,"scores entered")
print("Arithmetic Average:",total/count)
Explanation:
This initializes total and count to 0
total = 0; count = 0
This gets input for score
testscore = int(input("Score: "))
The following iteration stop when 999 is entered
while testscore != 999:
This prints out of range for scores outside 0 - 100
if testscore < 0 or testscore > 100:
print("Out of range")
Otherwise
else:
The total score is calculated
total+=testscore
The number of score is calculated
count+=1
Get another input
testscore = int(input("Score: "))
The number of score is printed
print(count,"scores entered")
The average of score is printed
print("Arithmetic Average:",total/count)

Explanation:
A wireless network facility provided in colleges, institutions, or libraries is secured with a proxy server to filter websites so that users can use the network facility for a definite purpose. Thus, that proxy server is not allowing access to all of the websites to the user on the internet except for two.
MAN speeds are faster than WAN speeds because of ________. technological limitations regulatory limitations
Answer:
economical reasons
Explanation:
A metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.
Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).
Hence, a wide area network (WAN) is designed to span over a very large geographical area and as such would cost more in implementing than a metropolitan area network (MAN) would cost.
This ultimately implies that, metropolitan area network (MAN) speeds are faster than WAN speeds because of economical reasons.

Answer:
The answer is "Remote access "
Explanation:
The capacity to access another computer or network that you do not have. Remote computer access provides an employee with remote access to the desktop and file. This assists an employee, for example, who works at home efficiently.
Remote users access documents or other resources on any network-connected device or server, enhancing organizational efficiency and increase there are to cooperate more interact with peers nation.
your organization has multiple remote offices. the users at the remote office often remotely connect to the application servers. which of the protocols should you enforce for encrypted communicationa
Answer:
RDP
SSH
Explanation:
RDP and SSH can both be used for remote encrypted communication. RDP protocol( called remote desktop protocol) is owned by Microsoft. It allows it's user access to the network through a GUI RDP software that allows you to connect to another computer on the network, the client server. RDPs operate over encrypted channels and is therefore secure.
SSH(called secure shell protocol) is used on Unix like OS systems to connect over unsecured network. SSH uses cryptographic encryption that increases security for it's client-server architecture. It's an improved version of RSH and Telnet which didn't make use of encryption when sending data over the network.

what can be the maximum possible length of an identifier 3163 79 can be of any length
Answer:
79 characters
Explanation:
The programming language is not stated, but a little search online shows the question is about python programming language
Literally, identifiers are the names given to variables, arrays and functions.
In most programming languages (e.g. python), identifiers are case-sensitive.
i.e. Abc is a different identifier when compared to abc.
Having said that, python allows up to 79 characters to name an identifier.
Meaning that, the length of a variable name (or array, or function, etc.) can be up to 79 characters, and it cannot exceed 79 characters.
A Linux systems admin reported a suspicious .py file that ran on a daily schedule after business hours. The file includes shellcode that would automate Application Programming Interface (API) calls to a web application to get information. What type of script is executing this shellcode
Answer: Python script
Explanation:
Based on the information given in the question, the type of script that is executing this shellcode is the Python script.
The Python script is a file that contains codes that are written in Python. In such case, the file which contains the python script typically has an extension
which is ".py"' or ".pyw" when it's run on windows
Therefore, based on the information given, the answer is Python script.
The type of script used in executing the shellcode that would automate Application Programming Interface (API) calls to a web application to get information is called; Python Script.
The type of script required to execute the given shellcode is called a python script. This is because the Python script is simply defined as a file that contains a code which is written in Python.
Now, this file which contains the python script will have the extension ‘.py’. However, if it is being run on a windows machine, it could also be the extension ‘.pyw’.
Finally, to run a python script, all we need to do is to get a python interpreter that we will download and install.

algo de La historia de los productos tecnologicos
Answer:
La tecnología se define como la suma de técnicas, habilidades, métodos y/o procesos utilizados y utilizados en la producción de bienes, productos o servicios, o para lograr objetivos clave de la investigación científica.
Precisamente, la tecnología se define como la aplicación del conocimiento científico con fines prácticos, especialmente en la producción industrial. Un significado secundario de la palabra se refiere al desarrollo de dispositivos y mecanismos con fines científicos y está directamente relacionado con las artes aplicadas, las ciencias aplicadas o la ingeniería. A veces se refiere a la metodología que caracteriza tal proceso. En los últimos años ha existido una tendencia a que el concepto se refiera únicamente a la alta tecnología y / o tecnología informática, aunque básicamente no se limita a estas áreas. Por ejemplo, tanto la Estación Espacial Internacional o una computadora pueden ser tecnología, también pueden ser un abridor de botellas estándar. A menudo, el objeto de la tecnología con beneficios prácticos no es el producto de la investigación científica, sino el resultado de un descubrimiento accidental.

When a primitive type variable is passed as an argument to a method, what is passed into the receiving method's parameter variable
Answer:
The value of the primitive type variable is passed into the receiving method
Explanation:
Examples of primitive data types are integers, floats, real, double, character, byte, etc.
When any of these data types variables are passed to a method, the method which receives the variables receives the value of the variable being passed.
Take, for instance; the following code segment:
int doubleNum(int num){ ..... }
int main(){ ... num = 2; doubleNum(num);}
The above function doubleNum will receive the value of num (which is 2).
Assume that processor refers to an object that provides a void method named process that takes no arguments. As it happens, the process method may throw one of several exceptions. Write some code that invokes the process method provided by the object associated with processor and arrange matters so that your code causes any exception thrown by process to be ignored. Hint: use the catch (Exception ex) and do nothing under the catch clause.
Answer:
Following are the code to the given question:
try//defining a try block
{
processor.process();//defining an object processor that calls process method
}
catch(Exception e)//defining a catch block
{
}
Explanation:
In this question, the 'Try' and 'catch' block is used in which both the keywords are used to represent exceptions managed during runtime due to information or code errors. This try box was its code block which includes errors. A message queue catches the block errors and examines these.
In the try block, a method "process" is used which is create the object processor that calls the method.
