A simple computer has a main memory and a disk but not a cache. If a referenced word is in main memory, 90ns are required to access it. If it is on disk but not in main memory, 10ms are needed to load it into main memory (this includes the time to originally check the main memory), and then reference is started again. The main memory hit ratio is 0.8. What is the average time in ns required to access a referenced word on this system

Answers

Answer 1

Answer:

The average time in ns to reference a work will be of 2,000,090.

Explanation:

80% of the time, you will need just to load from the main memory(when there is a hit), that is, a time of access of 90 ns.

20% of the time, you will have a miss, so you have to access the main memory(90 ns) plus the disk(10 ms = 10000000 ns).

So, the average time needed to reference a word will be:

[tex]t = 0.8*90 + 0.2*(90 + 10000000) = 2000090[/tex]

The average time in ns to reference a work will be of 2,000,090.

In the lab, you experimented with three different antivirus software applications: AVG, Windows Defender, and MalwareBytes. Why might someone use more than one application to protect their computer

Answers

Answer:

Explanation:

Different antivirus softwares use different techniques for analyzing data on a computer in order to find malware or any harmful data. This can provide extra layers of security to your computer and hopefully prevent harmful software from causing serious damage if they enter the system. Also every antivirus software has their own database of virus signatures which they use to compare and detect these viruses. Some may have info on these harmful viruses that others do not. Regardless it is not smart to have various antivirus software because they consume lost of computer resources and will ultimately slow down your computer.

Answers

Answer:

a. Encryption.

b. Authentication.

c. Strong.

d. Rogue.

e. Insecure.

f. Hacking.

Explanation:

In Computer technology, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Wireless networks have no clear boundaries, therefore securing communications requires strong encryption, authentication, and strong protocols. One of the most common wireless security threats is the presence of rogue access points (APs). Rogue points can be set up for the benign purpose of free wireless access or for malicious purposes, such as gaining access to confidential data. Using an insecure wireless hotspot, like so many found in public settings, leaves you vulnerable to become the victim of hacking.

What is the advantage of using shortcuts

Answers

Answer: There can be advantages and disadvantages.

for example, if you were in the woods with a pathway, and a clear way that might be faster and a shorter way of getting out. You may take the shortcut leading to where you didn't want to go leading to you getting lost or, it could be the same time but with more challenges.

An example of shortcuts to it's advantage is when you're reading a text and you don't understand the word. It's much easier when you hear it being read out to you when the reader uses tone to kind of give you a hint if the connotation is negative or positive, A good example of this is the word unique let's use this sentence "She was very unique, and that's what made her cool!" We can use the words "cool" to see that unique is a positive connotation! For the word cool can usually mean that something is real nice or it's something/someone you'd typically like to be around. So therefore these are just a few examples of the advantages and disadvantages of shortcuts.

Write a for loop to print all NUM_VALS elements of vector courseGrades, following each element with a space (including the last). Print forwards, then backwards. End with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:

10 11 9 7
Hint: Use two for loops. Second loop starts with i-courseGrades.size() - 1 (Notes)
Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element vector (vector int> courseGrades(4)). See "How to Use zyBooks".
Also note: If the submitted code tries to access an invalid vector element, such as courseGrades at(9) for a 4-element vector, the test may generate strange results. Or the test may crash and report "Program end never reached', in which case the system doesn't print the test case that caused the reported message.

One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector. This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings.
The class should have:
A private member variable called dynamicArray that references a dynamic array of type string.
A private member variable called size that holds the number of entries in the array.
A default constructor that sets the dynamic array to NULL and sets size to 0.
A function that returns size.
A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray, copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the old dynamicArray, and then set dynamicArray to the new array.
A function named deleteEntry that takes a string as input. The function should search dynamicArray for the string. If not found, return false. If found, create a new dynamic array one element smaller than dynamicArray. Copy all elements except the input string into the new array, delete dynamicArray, decrement size, and return true.
A function named getEntry that takes an integer as input and returns the string at that index in dynamicArray. Return "" string if the index is out of dynamicArray’s bounds.
Overload the operator[] so that you can get and change an element by an index integer. If the index is out-of-bounds, return a "" string.
A copy constructor that makes a copy of the input object’s dynamic array.
Overload the assignment operator so that the dynamic array is properly copied to the target object.
A destructor that frees up the memory allocated to the dynamic array.
Create a suitable test program to test your class.
You should name the project ASG10. When you zip up the project folder, ASG10, include all the files (.sln, .cpp, etc) and subdirectories (Debug, etc.).
**************************************************
Copy your DynamicStringArray from Assignment 10. Fix the program so all 13 tests work properly. Modify the definition of the overloaded operator [] and getEntry so they throw an OutOfRange exception if an index that is out of range is used. OutOfRange is an exception class that you define. The exception class should have a private int member and a private string member, and a public constructor that has int and string arguments. The offending index value along with a message should be stored in the exception object. You choose the message to describe the situation. Modify your test program and add tests that catch the new exception class.
You should name the project ASG14. When you zip up the project folder, ASG14, include all the files (.sln, .cpp, etc) and subdirectories (Debug, etc.).

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.

describe what measures should have been taken by the educational service and test preparation provider to avoid the security breach

Answers

Incomplete question. Here's part of the missing question;

The EducationS Review, a fictional company, is hit with a data breach that is making headlines. The Olianas-based educational service and test preparation provider inadvertently exposed files of at least 100,000 students in various parts of the country through its Web site. News of the breach was made public on Tuesday morning by a report in the local newspaper.

The files were exposed after the company switched the Internet service providers earlier this year. The sensitive information, which included personal data such as names, birth dates, ethnicities, and learning disabilities, as well as test performance, were easily accessed through a simple Web search and were available for at least seven weeks, according to the report. None of the information was password protected and was intended only to be viewed by EducationS authors.

Explanation:

It is important to note that the company did not make the information password protected, which creates a vulnerability.

Measures 1: only those with authentication password should have been allowed to access the information.

Measures 2:  prior to switching to a new internet service provider, an information risk assessment should have been done to ensure information security.

use the internet to research the SYSTEM account. Why is it nessesary to include this account with full control on a directory

Answers

Answer:

It is essential for the existence of a helicopter administration over all other users on the system.

 

Explanation:

A system account is a computer user account that is generated by an operating system (OS) during installation of the OS and that is utilized by the user in accordance to the parameters with which it has been designed and the purpose which it was created.

A System account is usually referred to as a privileged account because it comes with full control on one or more directories. A directory is simply a location for file storage on a computer. Full access or control includes the ability to:

read directorieswrite to directoriesmake changes to and delete files, folder and subfolders. alter authorization settings for all files and subdirectories.

Besides control on the directory level, System Accounts which are also called Super Accounts which in addition to the above have permission to

install  and remove software applicationsupdate and or upgrade the computers operating system access directories and files which normal users cannot and should not.

System Accounts are therefore important for security reasons. They are configured to act as a supervisory account which can create, authorise and terminate other accounts and processes.

Some of their merits include the ability to:

Oversee, audit, and completely control all other privileges. forestall cyber attacks on the system from internal users or insiders. Establish and provide evidence for compliance with regulatory codes
