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.

Fill in the blanks to complete this function (python):def add_prices(basket): # Initialize the variable that will be used for thecalculation total = 0 # Iterate through the dictionary items for ___: # Add each price to the totalcalculation # Hint: how do you access thevalues of # dictionary items? total += ___ # Limit the return value to 2 decimal places return round(total, 2)groceries = {"bananas": 1.56, "apples": 2.50, "oranges": 0.99,"bread": 4.59, "coffee": 6.99, "milk": 3.39, "eggs": 2.98, "cheese":5.44}print(add_prices(groceries)) # Should print 28.44
Answer:
def add_prices(basket):
total = 0
for items in basket.values():
total += items
return round(total, 2)
groceries = {"bananas": 1.56, "apples": 2.50, "oranges": 0.99,"bread": 4.59, "coffee": 6.99, "milk": 3.39, "eggs": 2.98, "cheese":5.44}

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.
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.
A data structure to store trees with an arbitrary number of children at each node is: public class TreeNode / Integer data, TreeNode firstChild; TreeNode nextSibling / Write a recursive Java method to return the leaf node with minimum value given the root of the tree. All elements are unique and if there are no leaf nodes you should return null. Your method signature should be: _______
Answer:
TreeNode minimum(TreeNode root) {
if (root != null) {
if (firstChild == null && nextSibling == null) {
return root;
} else {
TreeNode begin = minimum(root.firstChild);
TreeNode last = minimum(root.nextSibling);
if (begin == false && (last == false || begin.data < last.data)) {
return begin;
} else {
return last;
}
} else {
return null;
}
}
Explanation:
The Java program defines a recursive method called minimum that calls itself twice with the first and last leaf of the treenode as the respective arguments. and returns the minimum value of the treenode if the root argument is not undefined.

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 sum will amounts to Rs 1227 in 9 months at 6%
e emple Interest 2.
Answer:
given us,
principal (p)= Rs 1227
Time(t)= 9
Rate(r)= 6./.
Here,
simple interest= P×T×R/100
= 1227×9×6/100
= 66258/100
= 662.58
Explanation:
by using simple interest formula
The principal investment required to get a total amount, principal plus interest, of Rs 227.00 from simple interest at a rate of 6% per year for 0.75 years (9 months) is $1,174.16
Given Data
Final Amount A = Rs 1227
Time = 9 months
Rate = 6%
Principal = ?
Equation:P = A / (1 + rt)
Calculation:First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Putting time into years for simplicity,
9 months / 12 months/year = 0.75 years
Solving our equation:
P = 1227 / ( 1 + (0.06 × 0.75)) = 1174.1626794258
P = $1,174.16

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.
Which of these is an advantage of having multiple layers in a drawing and enables you to make changes to one part of an image without accidentally changing other parts it keeps the file size small and manageable it makes it easier to open the data file in different drawing applications it makes the print out a higher quality
Answer:
enables you to make changes to one part of an image without accidentally changing other parts
Explanation:
Computer aided designs incorporate the use of multiple layers in drawings. The first layer is known as the layer 0, while the present layer the designer is working on is known as the current layer. The advantage of the incorporation of layers in designs include the following
1. It helps objects to be altered, grouped, hidden and moved as the designer wishes.
2. Layers can be grouped and worked on separated and common properties like color and line weight assigned to them.
3. Layers can be manipulated as the user wishes. They can be locked, frozen, turned off, etc. Locking prevents accidental changes being made on objects.
