Explanation:
Answer:
Avatarlife of piThe Dark knightpirates of Caribbeanbeauty and beastThe following program is suppose to use the sin() function in the math library and write out an input's absolute value over an interval. So for example if sine(0.6) is 0.564 then its absolute value is the same (0.564). But if sine(2.4) is -0.675 then its absolute value is 0.675. #include #include /* has sin(), abs(), and fabs() */ int main(void) { double interval; int i; for(i = 0; i <30; i++) { interval = i/10.0; printf("sin( %lf ) = %lf \t", interval, abs(sin(interval))); } printf("\n+++++++\n"); return 0; }
Answer:
#include <stdio.h>
#include <math.h> /* has sin(), abs(), and fabs() */
int main(void) {
double interval;
int i;
for(i = 0; i <30; i++) {
interval = i/10.0;
printf("sin( %.1lf ) = %.3lf \t", interval, abs(sin(interval)));
}
printf("\n+++++++\n");
return 0;
}
Explanation:
The C source code defines a void main program that outputs the absolute value of the sine() function of numbers 0.1 to 3.0.
The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program statements in C language that completes the program are as follows:
interval = i/10.0;
printf("sin( %.1lf ) = %.3lf \t", interval, abs(sin(interval)));
The flow of the above statements is as follows
The first line determines the intervalThe second line prints the required output

Assume that x and y are boolean variables and have been properly initialized.(x && y) || !(x && y) The result of evaluating the expression above is best described as (A) always true (B) always false (C) true only when x is true and y is true (D) true only when x and y have the same value (E) true only when x and y have different values
Answer:
(A) Always true
Explanation:
Given
Boolean variables x and y
Required
What is (x && y) || !(x && y)
Irrespective of what x or y is, the x && y is always true
Take for instance:
x = true;
y = true;
x&&y will also be true because the values of x and y were not altered
And this is true for whatever boolean value x or y assume
Having said that:
x&&y = true
So, the expression is analysed as follows:
(x && y) || !(x && y)
Substitute true for x&&y
(true) || !(true)
!(true) = false
So, the expression becomes:
true || false
|| represents the OR operator; and it returns true if at least one of the conditions is true.
By this:
true || false = true
Option (A) Always true answers the question.

Three PCs are on an Ethernet LAN, connected by a hub. Describe how the Ethernet protocol deals with collisions in this situation. How would the situation change if the hub were replaced by a switch?
Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
What TCP message will be generated for an incoming SYN request for which is there no matching LISTENING port
Answer:
"Connection Refused"
Explanation:
This is the error message that is returned when the server is not listening on the correct port, or the server is offline.
Cheers.
The TCP message that will be generated for an incoming SYN request for which is there no matching LISTENING port is; “Connection Refused”.
TCP stands for Transmission Control Protocol and in the given situation in the question, the first step of the client application is to send the first packet with “SYN” flag.Now, when the above situation happens, the server will listen on the specified port and give a response of SYN-ACK packet so that it c an acknowledge the “SYN”packet requested by the client application which will generate a reply with ACK packet response that will make the established connection to end.
Finally, for an incoming SYN request for which is there no matching LISTENING port, the connection will be rejected with an “RST” flag that gives output an error message named “Connection Refused”.Read more about TCP at; https://brainly.com/question/24967184
What is computer virus?
Answer:
A piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.
Explanation:
A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.
Simply, a computer virus is a harmful multiplying code that harms your computer and makes it slower, harder to use, and more vulnerable to other harmful unsafe software, apps, downloads and more.
How to get it?
You can get computer viruses just from going to unsafe websites downloading harmful files downloading harmful images downloading harmful videos clicking unsafe advertisementsand thats just a couple of examples, there's many many more but you get the idea.
Something that really sucks about computer viruses is that its hard to tell if something online is dangerous or not.
That's why people make specific softwares to protect your computer but even those can be unsafe or people could be trying to trick you.
Sometimes the computer will already have some sort of app or software to protect it from these harmful files, but make sure to pay attention when your on websites and check the urls and make sure it doesn't say anything along the lines of "unsafe" if it says that just simply exit the website and dont do anything further.
If your experiencing slowness, files you don't remember saving on your computer or extra files and apps that dont seem to belong, im sure there are places you can call online or in your local area to help with these issues.

in spoofing internet attack, the attackers computer assumes false internet address in order to gain access to a network (true or false
Answer:
True.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.
Hence, in spoofing internet attack, the attacker's computer assumes false internet address in order to gain access to a network.
You are running your warehouse using Autonomous Data Warehouse (ADW) service and you noticed that a newly configured batch job is always running in serial even through nothing else is running in the database. All your jobs are configured to run with parallelism enabled.What could be the reason for this batch job to run in serial?A. The batch job depends on only one table and parallelism cannot be enabled on single-table queries.B. The parallelism of batch job depends on the number of ADW databases involved in the queryC. The new batch job is connected to LOW consumer group.D. The new batch job runs on database tables that are not enable for parallel execution.E. Parallelism on the database is controlled by the application, not the database.
Answer:
C. The new batch job is connected to the LOW consumer group.
Explanation:
Remember, one of the main characteristics of the LOW consumer group database service is that queries would run serially.
Since in this case, we are told that the newly configured batch job is always running in serial, it most likely would be because the new batch job is connected to the LOW consumer group; as queries are designed to always run serially.

Taylor and Rory are hosting a party. They sent out invitations, and each one collected responses into dictionaries, with names of their friends and how many guests each friend is bringing. Each dictionary is a partial list, but Rory's list has more current information about the number of guests. Fill in the blanks to combine both dictionaries into one, with each friend listed only once, and the number of guests from Rory's dictionary taking precedence, if a name is included in both dictionaries. Then print the resulting dictionary.
Answer:
Following are the code to this question:
def combine_guest(guest1, guest2):#defining a method combine_guest that accepts two dictionary
guest2.update (guest1)#use dictionary guest2 that use update method to update guest2 dictionary
return guest2#return guest2 dictionary values
Rory_guest= { "Ada":2, "Ben":3, "Dav":1, "Jo":3, "Charry":2, "Terry":1, "bob":4}#defining a dictionary and add value
Taylor_guest = { "Dav":4, "Nan":1, "bobert":2, "Ada":1, "Samantha":3, "Chr":5}#defining a dictionary and add value
print(combine_guest(Rory_guest,Taylor_guest))#calling the combine_guest method
Output:
{'Nan': 1, 'Samantha': 3, 'Ada': 2, 'bob': 4, 'Terry': 1, 'Jo': 3, 'Ben': 3, 'Dav': 1, 'Charry': 2, 'bobert': 2, 'Chr': 5}
Explanation:
In the code a method, "combine_guest" is defined, that accepts two dictionaries "guest1, guest2" inside the method, in which the "guest2" dictionary uses the update method to combine the value of the guest1 dictionary and use a return keyword to return guest2 values.
In the next step, two dictionaries are declared, that holds some values and use a print method to call the "combine_guest" method and prints its return values.

When writing code, how can printing be useful?
Answer:
See Explanation
Explanation:
Printing while writing code can be useful in several ways.
One of which is to determine the progress of your code. Many a times when you write a code and some parts of your codes are not working as expected, you can use the print statement to track where the program stopped working properly.
Take for instance, you write a program of 50 lines of code and you suspect that the program stops working at line 30, you can use the print statement to track this program.
Please note that: the statement to be printed is not specific but you should make use of something unique that you can easily spot.

Once you start designing the processing logic for each function of your software, you might end up throwing out your logical data model design and completely redesigning it.
a
False
b
True
Answer:
B. True.
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
Hence, once you start designing the processing logic for each function of your software, you might end up throwing out your logical data model design and completely redesigning it because each function would use a specific processing logic respectively.
