(a) mkdir /d D:\utilities\recover
or
mkdir D:\utilities\recover
(b) rd /s D:\software\arch98
Explanation:(a) To make a new directory we use the md or mkdir command followed by the name of the directory as follows;
mkdir [name_of_directory]
The name of the directory could also be a relative or absolute path depending on the request.
In the task, the specified directory uses an absolute path given as D:\utilities\recover. This path is in a drive D. Therefore, if you are in another drive different than D, to run this command, it is a great idea to do that with the /d switch.
In summary:
i. if in drive D, to make a directory D:\utilities\recover, type the following command;
mkdir D:\utilities\recover
ii. if otherwise in a different drive, type the following command.
mkdir /d D:\utilities\recover
(b) To delete a directory, we use the rd or rmdir command. If the directory has contents that also need to be deleted, we use the switch /s alongside the rd or rmdir.
In the task given, the directory to be deleted is D:\software\arch98. This includes deleting all of its files too. To do this, type the following command;
rd /s D:\software\arch98
What does the abbreviation BBC stands for?
Answer:
British Broadcasting Corporation Microcomputer System
Explanation:
The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by the Acorn Computer company in the 1980s for the BBC Computer Literacy Project.
Answer:
British Broadcasting Corporation
Explanation:
This is a UK company which provides television and radio news in over 40 languages. This is the computer related meaning, there are other meanings to the abbreviation but they seem irrelevant in this case.
Hope this information was of any help to you. (:
Write an application that inputs a five digit integer (The number must be entered only as ONE input) and separates the number into its individual digits using MOD, and prints the digits separated from one another. Your code will do INPUT VALIDATION and warn the user to enter the correct number of digits and let the user run your code as many times as they want (LOOP). Submit two different versions: Using the Scanner class (file name: ScanP2)
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
int n, num;
Scanner input = new Scanner(System.in);
System.out.print("Number of inputs: ");
n = input.nextInt();
LinkedList<Integer> myList = new LinkedList<Integer>();
for(int i = 0; i<n;i++){
System.out.print("Input Integer: ");
num = input.nextInt();
while (num > 0) {
myList.push( num % 10 );
num/=10;
}
while (!myList.isEmpty()) {
System.out.print(myList.pop()+" ");
}
System.out.println();
myList.clear();
}
}
}
Explanation:
This declares the number of inputs (n) and each input (num) as integer
int n, num;
Scanner input = new Scanner(System.in);
Prompt for number of inputs
System.out.print("Number of inputs: "); n = input.nextInt();
The program uses linkedlist to store individual digits. This declares the linkedlist
LinkedList<Integer> myList = new LinkedList<Integer>();
This iterates through n
for(int i = 0; i<n;i++){
Prompt for input
System.out.print("Input Integer: ");
This gets input for each iteration
num = input.nextInt();
This while loop is repeated until the digits are completely split
while (num > 0) {
This adds each digit to the linked list
myList.push( num % 10 );
This gets the other digits
num/=10;
}
The inner while loop ends here
This iterates through the linked list
while (!myList.isEmpty()) {
This pops out every element of thelist
System.out.print(myList.pop()+" ");
}
Print a new line
System.out.println();
This clears the stack
myList.clear();
}
A capacitor of capacitance 102/π µF is connected across a 220 V, 50 Hz A.C. mains. Calculate the capacitive reactance, RMS value of current and write down the equations of voltage and current.
Answer:
The capacitive reactance will be "100Ω" and RMS value of current is "2.2 A". A further explanation is provided below.
Explanation:
Given:
[tex]C =\frac{10^2}{\pi}\times 10^{-6} \ F[/tex]
[tex]V_{RMS}=220 \ V[/tex]
[tex]f = 50 \ Hz[/tex]
Now,
The capacitive reactance will be:
⇒ [tex]X_c=\frac{1}{\omega C} =\frac{1}{2 \pi f C}[/tex]
[tex]=\frac{1}{2\times \pi\times 50\times \frac{10^{-4}}{\pi} }[/tex]
[tex]=100 \ \Omega[/tex]
RMS value of current will be:
⇒ [tex]I_{RMS}=\frac{V_{RMS}}{X_c}[/tex]
[tex]=\frac{220}{100}[/tex]
[tex]=2.2 \ A[/tex]
So that,
⇒ [tex]V_m=220\times \sqrt{2}[/tex]
[tex]=311 \ V[/tex]
⇒ [tex]I_m=2.2\times \sqrt{2}[/tex]
[tex]=3.1 \ A[/tex]
hence,
The equation will be:
⇒ [tex]\nu=311 sin31 \ 4t[/tex]
and,
⇒ [tex]i=3.1 sin(314t+\frac{\pi}{2} )[/tex]

Used for monitoring web activity by users to make sure that sensitive information won't leave the building.
A, Web server
B, FTP server
C, POP server
D, Proxy server
Answer: PROXY
Explanation:
The basic objective of the web server is to store, process and deliver web pages to the users.
FTP server is to allow users to upload and download files. An FTP server is a computer that has a file transfer protocol (FTP) address and is dedicated to receiving an FTP connection. FTP is a protocol used to transfer files via the internet between a server (sender) and a client (receiver)
pop provides access via an Internet Protocol (IP) network for a user client application to a mailbox (maildrop) maintained on a mail server
proxy server is a system that isolates internal clients from the servers by downloading and storing files on behalf of the clients. it intercepts requests for web-based or other resources that come from

Frames control what displays on the Stage, while keyframes help to set up
Answer: A keyframe is a location on a timeline which marks the beginning or end of a transition. So for example, you have a movie and it transitions to another scene, keyframes tell it when and where to start the transition then when and where to stop the transition.
