A) RAID 0
B) RAID 1
C) RAID 3
D) RAID 5
Answer:
D. RAID 5
Explanation:
Raid ( Redundancy array of inexpensive disk or drives) levels are used to boost performance and reliability of storage devices. They consist of hard drives or solid state drives working parallel to each other.
There are different levels of RAID, they are;
Raid 0, 1, 2, 3, 4, 5 and 10. Raid 2, 3, 4 and 7 are not really is use, so, we pay attention to 0, 1, 5 and 10.
Raid 0 only splits data to not list two drives and are not redundant. Raid 1 mirrors or reflects data on at least two drives and are also not redundant.
Raid 5 is redundant as it share data and parity bits between 16 or more drives.
Unlike Raid 5, Raid 10 does not have parity bits.
A crossover cable would normally be used in a 100BaseT network to connect __________.
Answer:
The answer is "directly computing device"
Explanation:
The Ethernet crossover cable used to connect computers directly. Two computers are used in the same form in this method and are mostly related.
The system is connected to two or more switches, and a mini LAN connected to one LAN or two separate hosts. It allows the connection to two hosts or a server to a customer without having a hub.Final answer:
A crossover cable is used in a 100BaseT network to directly connect two similar devices, such as computers, or networking equipment like switches and routers. This cable type crosses transmit and receive lines to enable direct communication, employing twisted pair wiring to minimize crosstalk and interference.
Explanation:
A crossover cable is typically used in a 100BaseT network to connect two similar devices directly to each other without the need for a switch or hub. This type of cable is useful for linking two computers together to form a small network or for connecting switches and routers without uplink ports. The wires within a crossover cable are crossed so that the transmitting signals on one end of the cable line up with the receiving signals on the other end, enabling two devices to communicate directly. Connections utilizing a crossover cable are critical in networks that operate at frequencies up to a few hundred kHz, and they also apply to systems such as Ethernet which can operate near 1 GHz. The use of twisted pair cables, like those in crossover cables, help to reduce crosstalk and other electromagnetic interference which would otherwise be problematic in both power and data transmission.
A graphic designer purchased a new device. The purpose is to convert her sketches that she drew on paper to a digital format. She connects the device to her computer via USB. However, the device is not recognized by her computer.
What is the next step?
a. She must locate and install the driver for her stylus.
b. This output device is not compatible.
c. She must purchase a device manufactured by the same manufacturer as her computer.
d. She must locate and install the driver for her scanner.
Final answer:
The correct step when a computer does not recognize a newly connected device is to locate and install the appropriate driver for that device, in this case, a driver for her scanner.
Explanation:
When a graphic designer's new device is not recognized by the computer after being connected via USB, the next step would typically involve troubleshooting to ensure proper installation and connectivity. In this scenario, the correct course of action would be to locate and install the driver for the device in question. If the device in question is a scanner, which is commonly used to digitize sketches, option d would be the appropriate choice:
She must locate and install the driver for her scanner.
Drivers are software components that enable the operating system to communicate with hardware devices. Without the proper driver, the system may fail to recognize the device. Installing the correct driver normally resolves issues of device detection. It is unnecessary to purchase a device from the same manufacturer as the computer or to assume that the device is not compatible without first attempting driver installation.

Write a method called all Less that accepts two arrays of integers and returns true if each element in the first array is less than the element at the same index in the second array. For example, if the two arrays passed are {45, 20, 300} and {50, 41, 600}, your method should return true. If the arrays are not the same length, you should return false.Test your method and print out to the screen in main() function the following callsa. all Less(arr1, arr2); (where arr1 = [1,2,3,4,5], arr2 = [4,5,6,7,8])b. all Less(arr1, arr2); (where arr1 = [1,2,3,4,5], arr2 = [5,6,7,8])c. all Less(arr1, arr2); (where arr1 = [5,2,3,4,1], arr2 = [4,5,6,7,8])d. all Less(arr1, arr2); (where arr1 = [5,5,3,4,5], arr2 = [9,9,9,9,1])
Answer:
The program to this question can be given as:
Program:
#include<iostream> //header file
using namespace std; //using name space
bool allLess (int arr1[], int arr2[]) //defining method allLess
{
int a,b; //define variable
a= *(&arr1 + 1) - arr1; //hold length of arr1
b= *(&arr2 + 1) - arr2; //hold length of arr2
if(a!=b) //checking condition
{
return 1; //return value
}
for(int i=0; i<a; i++) //loop
{
if( arr1[i]>=arr2[i]) //checking condition
{
return 1; //return value
}
}
return 0; //return value
}
int main() //define main method.
{
int arr1[]={1,2,3,4,5}; //define array arr1 and assign value.
int arr2[]={4,5,6,7,8}; //define array arr2 and assign value.
cout<< allLess(arr1,arr2); //function calling
return 0;
}
Output:
1
Explanation:
The Explanation of the C++ language program can be given as follows:
In the above program firstly we include the header file. Then a method is defined that is "allLess" this method accepts two arrays that are "arr1 and arr2". This function returns a boolean value that is true or false. Inside a function, we define a conditional statement and a loop in the if block we check the length of the arr1 array variable is not equal to arr2 array length. if this condition is true it will return false. In the loop, we define another if block in this block we check that if arr1 array elements are grater then equal to arr2 array element if this condition is true it will return false. At the end of both if block and loop the function will return a value that is "true". In the main method, we define two arrays and pass to the function and use (cout function) for print return value.Wi-Fi networks operate in basically the same way as cellular telephony networks that are designed, installed, and maintained by the wireless telephone carriers.

A single central register of IP addresses and names (a DNS style system) is an efficient means of translating human readable names to IP addresses. Which of the following is NOT solved by DNS?
A. It is inefficient to have everyone on the Internet maintain their own list of IP addresses.
B. There are too few IP addresses to meet the current demand.
C. When someone new joins the Internet they must inform everyone else of the new IP address
D. When an IP address changes, it is impossible to locate a computer until the owner announces the change.
Answer:
Option B: There are too few IP addresses to meet the current demand.
is the correct answer
Explanation:
As the demand of changing human names to IP addresses, it is difficult to meet because the human names can be uncountable and unlimited while in comparison to the IP addresses are somehow limited.
As IP addresses should be unique so that they maybe identified so the this uniqueness factor will not be able to fulfilled when we try to change all the names to IP addresses.

Larry is responsible for NIDS/NIPS in his company and has configured a new NIPS solution. What part of this device collects data?
Answer:
Sensor collects data of this device
Explanation:
A network intrusion protection system (NIPS) includes hardware and software systems that protect computer networks and prevent unauthorized access and malicious events.
NIPS hardware consists of a Network Intrusion Detection System (NIDS) which detects malicious activities, denial of service attacks on a computer or network by monitoring network traffic and detecting suspicious patterns in data packets. Three basic component of this system are sensor, control unit, and annunciator. This intrusion detection system collect data using sensor.
NIDS consists of sensors, which passively inspect network traffic for malicious activity. A sensor is a software and hardware device. A sensor can work as a Network Terminal Access Point (TAP) or a firewall log. It collects information about network. Sensor can be used to make decisions about your network’s security. Data collected from multiple sensors make information and traffic monitoring efficient as it generate different types of data and can be created to perform different functions.

You are on a roller coaster and enter a loop, traveling on the inside of the loop. You pull positive Gs. What provides the centripetal force to make you move in a circle?
Answer:
While traveling on the inside of the loop, you will pull positive Gs and acceleration provides the centripetal force that pushes you against your roller coaster seat.
Explanation:
Due to acceleration, centripetal force keep roller coasters on their tracks and people in their seats. Centripetal force points to the inside of the loop and the car needs to travel fast in order to apply enough centripetal acceleration the roller coaster entering the loop.
When the cars are on the track, gravity pulls downward at a constant magnitude, but as it speeds up almost at the top of the loop, it and the track add together with the centripetal force.

Show you know how this works by reconstructing the original text from the dictionary and compressed version?
Answer:
Explanation:
There is a web application where we compress text with some symbols.
For example:
A simple example can be
aaaaaaaaaaaaaaaaa = ☀
But we can make more complex example
☂☃☄☀ = hola
If we use this same rule, we can compress more long sentence
h = ☂
o = ☃
l = ☄
a = ☀
☂☃☄☀_☀_t☃d☃_e☄_mund☃_est☃y_☀qui_p☀r☀_c☃mprimir_text☃
Without the compress
hola_a_todo_el_mundo_estoy_aqui_para_comprimir_texto
Even we can make this compress with entire words
☀_☉_★_☊_☂_☈_☇_☆_☃_☄ = hola a todo el mundo estoy aqui para comprimir texto .
Compressed text size: 19 bytes
Original text size: 52 bytes
The rule is:
hola = ☀
mundo = ☂
comprimir = ☃
texto = ☄
todo = ★
para = ☆
aqui = ☇
estoy = ☈
a = ☉
el = ☊

Lenovo's ThinkPad laptop computers is designed in the United States, the case, keyboard, and hard drive are made in Thailand; the display screen and memory in South Korea; the built-in wireless card in Malaysia; and the microprocessor in the United States. In each case, these components are manufactured and sourced from the optimal location given current factor costs. In this example, Lenovo has:a. Vertical integration advantagesb. A global web of value creation activitiesc. High local responsivenessd. Learning effects
Answer:
b. A global web of value creation activities
Explanation:
Multinational companies can benefit from creating a global network of value creation activities. With this strategy various phases of the value chain are distributed in several global locations where the cost of value creation is greatly reduced and value maximized. In this scenario Lenovo strategically chooses locations for the manufacturing of components for their ThinkPad laptops, while factoring costs involved and ensuring they are at a minimum. As with any strategy, it has its limitations that can reduce effectiveness such as trade barriers and other political risks.
When reading data across the network (i.e. from a URL) in Python 3, what string method must be used to convert it to the internal format used by strings?
Answer:

Explanation:
We can use the method decode( ) to decode the string using the codec registered for encoding.
There are two parameters
encoding: We can encode with this parameter.
errors: If used to manage the errors.
For example:
String = "this is string example....wow!!!";
String = Str.encode('base64','strict');
If we print these variables we have:
String = b'dGhpcyBpcyBzdHJpbmcgZXhhbXBsZS4uLi53b3chISE='
String = this is string example....wow!!!
When designing your navigation, your primary objective should be to include keywords for search engines.
a) true
b) false
Answer:
Option b is the correct answer for the above question.
Explanation:
When a user creates a website then he should need to put navigation on that because navigation is a collection of the list followed by a link which is used to transfer the user to the other page of that website. For example, if a user makes a website of the student, then the navigation will hold the link of student detail, about us and login.
But search engine keywords are used to find the website easily on the internet which is important when a user lives his website but it is not important when a user creates a website. But the above question statement says that it is important while creating a website in the navigation bar which is not correct.
Hence Option b is the correct answer which states that the question statement is a false statement.
Which of the following is true of the learning phase of Web site production? It orients the designer to consider how audiences will use the Web site and where they will access it. It involves seeking information from clients about what they want in a Web site. The wireframe is developed to look like the final product, often in Photoshop or some other graphics program. The template is transformed into a working Web site. The completed and approved site is launched into the world.
Answer:
Option B is the correct answer to the following question.
Explanation:
Because the website production involves in looking for the information or data from the clients as related to the website, without the information the website developer unable to create our clients website and the first thing before creating the website is the information about what type of website the client wants after that, developer plan how to create his website before start.
The learning phase of website production is crucial for understanding how users interact with the site and for gathering client requirements. It involves creating a wireframe that outlines content placement without final design elements, followed by storyboarding with initial designs
During the learning phase of website production, designers must consider various important aspects before the actual development of the website begins. The main purpose of this phase is to orient the design around how audiences will interact with the website and to gather an understanding of the website's goals from the client. Often this phase includes developing a site wireframe, which serves as a blueprint for the website layout, highlighting the placement and size of content elements, but not the design specifics such as style or color.
Site wireframes are created keeping in mind the content elements and their locations, without delving into specific design attributes. The process extends into storyboarding, where initial designs including color schemes, typography, and rough images are added using graphic editors. This is completed before any coding begins, allowing for a thorough understanding of the website's structure, which ultimately facilitates the development process.
The following statement calls a function named half, which returns a value that is half that of the argument. (Assume the number variable references a float value.) Write code for the function.
Answer:
The function definition to this question can be given as:
def half (number): #defining a function half and pass a variable number in function parameter
return number/2 #returns value.
data=half(12) #defining variable data that holds function return value
print(data) #print value.
Output:
6.0
Explanation:
In the above python program, a function that is half is declare that includes a variable number in the function parameter. Inside the function, the parameter value that is number is divided by 2 and returns its value. In calling time a data variable is defined that holds the function half() value.
In calling time function holds value that is "12" in its parameter and return a value that is "6.0".
Final answer:
The student requested code for a function named 'half' that returns half the value of a float argument. The Python function 'def half(number): return number / 2.0' fulfills this request.
Explanation:
The student has asked for code to be written for a function named half, which returns a value that is half that of its argument, where the argument is a float value. Let's define this function in Python, as it is commonly used in educational contexts:
def half(number):
return number / 2.0
To use this function, you would just call half with the number variable as its argument like this: result = half(number). This function simply takes the argument number, divides it by 2, and returns the result. If number is a float, the result will also be a float representing half of the original value.
Pick the two statements about packets and routing on the Internet which are true. a. Packets travelling across the Internet take a standardized amount of time and so can be counted on to arrive in the order they were sent b. TCP ensures messages can be reliably transmitted across the Internet c. TCP depends on the infrastructure of the Internet to be reliable enough to ensure no packets are lost in transmission d. TCP must account for the fact that packets may not arrive at a destination computer in the intended order
Answer:
B. TCP ensures messages can be reliably transmitted across the Internet.
D. TCP must account for the fact that packets may not arrive at a destination computer in the intended order
Explanation:
TCP or transmission control protocol is a connection oriented protocol that divides a packet to segments, and reliably sends them to their destination.
TCP is a layer 4 (transport layer) protocol in the OSI network model. Its packets data unit, PDU, is called segment.
For TCP connection to be successful, a three way handshake must be established between the client and server.
When a connection is established, tcp sends the packets in sequenced segments to the destination through various routes, the source receives acknowledgement for segments received by the destination and the source resend segment that were lost. In the destination, the TCP arranges the segments to its proper sequence.
