Answer:
Lack of global control.
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
There are different types of operating systems (OS) used for specific purposes and these are;
1. Batch Operating System.
2. Multitasking/Time Sharing OS.
3. Multiprocessing OS.
4. Single User OS.
5. Mobile OS.
6. Real Time OS .
7. Distributed OS.
8. Network OS.
A network operating system (NOS) can be defined as specialized computer operating system that are designed primarily for use on network devices such as routers, switches, workstations, which are mainly connected to a local area network.
Generally, the biggest limitation of a network operating system (NOS) is lack of global in terms of memory, process, device, and file management.
The given SQL creates a Movie table and inserts some movies. The SELECT statement selects all movies released before January 1, 2000 Modify the SELECT statement to select the title and release date of PG-13 movies that are released after February 1, 2008. Run your solution and verify the result table shows just the titles and release dates for The Dark Knight and Crazy Rich Asians. 3 6 1 CREATE TABLE Movie ( 2 ID INT AUTO_INCREMENT, Title VARCHAR(100), 4 Rating CHAR(5) CHECK (Rating IN ('G', 'PG', 'PG-13', 'R')), 5 ReleaseDate DATE, PRIMARY KEY (ID) 7); 8 9 INSERT INTO Movie (Title, Rating, ReleaseDate) VALUES 19 ('Casablanca', 'PG', '1943-01-23'), 11 ("Bridget Jones's Diary', 'PG-13', '2001-04-13'), 12 ('The Dark Knight', 'PG-13', '2008-07-18'), 13 ("Hidden Figures', 'PG', '2017-01-06'), 14 ('Toy Story', 'G', '1995-11-22'), 15 ("Rocky', 'PG', '1976-11-21'), 16 ('Crazy Rich Asians', 'PG-13', '2018-08-15'); 17 18 -- Modify the SELECT statement: 19 SELECT * 20 FROM Movie 21 WHERE ReleaseDate < '2000-01-01'; 22
Answer:
The modified SQL code is as follows:
SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate > '2008-02-01'
Explanation:
The syntax of an SQL select statement is:
SELECT c1, c2, c...n FROM table WHERE condition-1, AND/OR condition-n
In this query, we are to select only the title and the release date.
So, we have:
SELECT Title, ReleaseDate
The table name is Movie.
So, we have:
SELECT Title, ReleaseDate FROM movie
And the condition for selection is that:
Ratings must be PG-13
And the date must be later than February 1, 2008
This implies that:
Rating = "PG-13"
ReleaseDate > '2008-02-01'
So, the complete query is:
SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate > '2008-02-01'

1) Create a class called Villain. Specifically, a Villain has the following fields: .name (String)
a number of evil plans (int) In addition, a Villain has the following methods: • a constructor that accepts an argument for each of the fields . a copy constructor
an equals method, which checks/returns whether all the fields are the same
a toString method
2) Create a class called Crazy Villain, which inherits from Villain. Specifically, a Crazy Villain has the following additional fields:
a crazy laughter (String)
a crazy idea (String In addition, write code for the following Crazy Villain methods:
a constructor that accepts an argument for each of the fields
a toString method that overrides the Villain toString method, in order to include the additional fields You do not need to instantiate/demo Villain or Crazy Villain objects.
Answer:
Explanation:
The following code is written in Java and creates both of the classes as requested with their variables and methods as needed. The crazyVillain class extends the Villain class and implements and overrides the needed variables and methods. Due to technical reasons, I have added the code as a txt file below.
Write a program that reads in a text file, infile.txt, and prints out all the lines in the file to the screen until it encounters a line with fewer than 4 characters. Once it finds a short line (one with fewer than 4 characters), the program stops. Your program must use readline() to read one line at a time. For your testing you should create a file named infile.txt. Only upload your Python program, I will create my own infile.txt using break
Answer:
Explanation:
f=open("infile.txt","r")
flag=True
while(flag):
s=f.readline().strip()
if(len(s)>=4):
print(s)
else:
flag=False

Answer:
I don't know how to code C++
Explanation:
List to String (0.5 points) Since we are often dealing with a list of strings, it would be useful to have a function to tum a list of strings back into one single concatenated string, This function will return a string that is each element of input_list concatenated together with each separated by the string Separator For example, the following function call: list_to_string('This', 'is's 'fun' should return; "This is fun To do this, write a function called list_to_string This function should have the following inputs, outputs, and internal procedures: Input(s) input_list - list of strings . separator - string Output(s); . output - string Procedure(s): - assign a variable called output to be the first (index 0) element from input_list - loop through the rest of input_list, looping from the 2nd element index 1) through to the end of the list - Within the loop, use string concatenator to combine output with the current element, separated by separator • Assign the output of this to be the new value of output • return output, which should now be a list of the elements of input_list joined together into a single string
Answer:
The function is as follows:
def list_to_string(input_list,separator):
output = ""
for inp in input_list:
output+=inp+separator
output = output[:-1]
return output
Explanation:
Given
See attachment for instruction
Required
A function to convert list to string
This defines the string
def list_to_string(input_list,separator):
This initializes the output to an empty string
output = ""
This iterates through the input list
for inp in input_list:
This concatenates every string in the list including the separator
output+=inp+separator
This removes the last character of the string
output = output[:-1]
This returns the output string
return output
Write a new method in the Rectangle class to test if a Point falls within the rectangle. For this exercise, assume that a rectangle at (0,0) with width 10 and height 5 has open upper bounds on the width and height, i.e. it stretches in the x direction from [0 to 10), where 0 is included but 10 is excluded, and from [0 to 5) in the y direction. So it does not contain the point (10, 2). These tests should pass:
Answer:
Explanation:
The Rectangle and Point class is not provided in this question but was found online. Using that code as guidance I created the following method named contains. This method takes in a Point object and checks to see if the x-axis point is inside the parameters of the Rectangle class and then checks the same for the y-axis. If it is inside the Rectangle then the method returns true otherwise it returns false.
def contains(self, point):
return self.width > point.x >= self.corner.x and self.height > point.y >= self.corner.y
Your assignment is to write an assembly language program which read a string and print it in uppercase. This program asks the user to enter a string which is subsequently displayed in uppercase. It is important to first ensure that string to be converted is in the a-z range. The program does not recognize any space, symbols or any kind of punctuation marks. Any time the user enters any of this character the program is going to repeatedly ask for the valid string.
An example execution of your program could be:
Please enter your string: 1winter
Invalid Entry!
Please enter your string: summer
Your capitalized string:SUMMER

You have configured a LAN with 25 workstations, three network printers, and two servers. The workstations and printers will have dynamically assigned IP addresses, and the printers always need to have the same IP address assigned. The servers will have static IP addresses. What should you install on one of the servers, and what are some of the configuration options
Answer:
install and configure on the server DHCP (Dynamic Host Configuration Protocol)
Explanation:
In this scenario, you should install and configure on the server DHCP (Dynamic Host Configuration Protocol), this protocol automatically assigns each individual PC a unique IP address and DNS server information. This protocol has various configuration options such as being able to set a range for the IP addresses so that they can be used by different devices in the system. It also allows you to directly set the subnet and passage gateway so that all of the workstations can quickly communicate with one another and quickly be targeted by the administration.

D. sheet tab
PATULONG PO PLS
Answer: A. Cell
Explanation:
A cell is the point on the worksheet that results from the intersection of a column and a row.
This is why cells can be identified by the column and row that they are the result of. For instance, a cell can be called "A12" which is also known as its "address". This means that it is a result of the intersection of "Column A" and "Row 12".

A security technician is configuring a new firewall appliance for a production environment. The firewall must support secure web services for client workstations on the 10.10.10.0/24 network. The same client workstations are configured to contact a server at 192.168.1.15/24 for domain name resolution.
Required:
What rules should the technician add to the firewall to allow this connectivity for the client workstations
Answer:
Explanation:
Based on the information provided in the question, the best rules that the technician should add to the firewall would be the following
Permit 10.10.10.0/24 0.0.0.0 -p tcp --dport 443
Permit 10.10.10.0/24 192.168.1.15/24 -p udp --dport 53
This is because port 443 is used for "Secure webs services" while UDP port 53 is used for queries and domain name resolution. Both of which are the main configurations that the security technician needs to obtain.
