Answer:
A switch
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a hub, a router, printer, a switch, etc.
In computer networking, a switch is a network hardware (device) that breaks up a network into separate collision domains within a single broadcast domain. Thus, it's commonly configured with virtual local area network (VLAN) to break up and interconnect multiple networks.

Can anyone decipher these? There a bit random. Maybe binary but if there are other ways please include them.
Answer:
Explanation:
so this is what "format" is about, it's saying what do the ones and zeros represent. b/c the bits can represent lots of different things , like letters with ascii code , and that's got several types. some are 8 bits, some are 16 bits, the questions you've shown are in groups of 5 which is really not a "thing" in binary, it's always by twos, without some type of "frame work" around the bits, we won't know what they represent, if that is helping? the important part is what is the "frame work" that these bits are in.
all of your questions seem to have some "art" thing going on, they make some kinda of binary artwork, for what they are saying, that's not what's important. Other than if they form palindromes, maybe that's what the questions are really about, how these do from palindromes, that is, they read the same backwards as forwards... I know.. why would anyone read backwards.. but a computer can do that pretty quickly, sooo sometimes to check, it will read forwards and backwards.. but when there is a palindrome, the computer is "confused"
this is also a big big part of "typing" not like on a keyboard but when you program, and you say that your variables are of a certain type, like a char, or a string, or a double, you are specifying how many bits will be used to represent your data. so then when you put the ones and zeros into the memory , ( think RAM) then it's stored in groups of what ever size you've determined. hmmmm does this help?

When implementing a 1:1 relationship, where should you place the foreign key if one side is mandatory and one side is optional? Should the foreign key be mandatory or optional?
Answer:
When implementing a 1:1 relationship, the foreign key should be placed on the optional side if one side is mandatory and one side is optional.
When this is implemented, the foreign key should be made mandatory.
Explanation:
A foreign key (FK) is a primary key (PK) in relational databases. It is used to establish a relationship with a table that has the same attribute with another table in the database. A mandatory relationship exists when the foreign key depends on the parent (primary key) and cannot exist without the parent. A one-to-one relationship exists when one row in a data table may be linked with only one row in another data table.

C. Using a protocol other than TCP/IP can result in data loss.
D. Computers that are distributed across a large geographic area need a special protocol to resolve errors.
The statement that is true about network protocols is that:
Using a protocol other than TCP/IP can result in data loss.What are network protocols?A network protocol is a system of principles that governs how data is delivered between devices on the same network.
Primarily, it enables linked devices to interact with one another despite variations in internal operations, architecture, or design.
The way this is done is true the use of Transmission-control protocol/Internet protocol (TCP/IP).
TCP/IP is the primary protocol or communication language of the Internet. Therefore, using a protocol other than TCP/IP can result in data loss.

Write a program that reads in the size of the side of a square and then prints a hollow square of that size out of asterisks and
blanks. Your program should work for squares of all side sizes between 1 and 20. For example, if your program reads a size of 5, it
should print
Answer:
Explanation:
#include <iostream>
using std::cout;
using std::endl;
using std::cin;
int main()
{
int side, rowPosition, size;
cout << "Enter the square side: ";
cin >> side;
size = side;
while ( side > 0 ) {
rowPosition = size;
while ( rowPosition > 0 ) {
if ( size == side || side == 1 || rowPosition == 1 ||
rowPosition == size )
cout << '*';
else
cout << ' ';
--rowPosition;
}
cout << '\n';
--side;
}
cout << endl;
return 0;
}

Preserving confidentiality, integrity, and availability is a restatement of the concern over interruption, interception, modification, and fabrication.
i. Briefly explain the 4 attacks: interruption, interception, modification, and fabrication.
ii. How do the first three security concepts relate to these four attacks
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.
RecursionexerciseCOP 3502; Summer2021We have gone through many examples in the class and those examples are available in the slides and uploaded codes. Try to test those codes and modify as you wish for getting more clarification.In additiontry the following:---------------------------------------------------------------------------------------------------------------------------------------1.What would be the output of the following recursive function if we call rec2(5)
Answer:
The output is:
1 2 3 4 5
Explanation:
Given
See attachment for code segment
Required
The output of rec2(5)
From the attached code segment, we have the following:
The base case: if (x==0){ return;}
The above implies that, the recursion ends when the value of x gets reduced to 0
The recursion:
rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function
printf("%d ", x); This prints the passed value of x
Hence, the output of rec2(5) is: 1 2 3 4 5
The fastest way to pull financial data from the application into Excel as refreshable formulas that can be edited or updated is:
Answer:
Download the financial report as =FDS codes with cell referencing.
Explanation:
An excel is a spreadsheet that is developed by the Microsoft company for the Windows operating system. It can be also used in iOS, macOS and Android. It has many features including graphing tools, calculation, pivot tables, etc.
In excel the fastest way to pull out a financial data from an application into the Excel as the refreshable formulas which can be edited or can be uploaded later on is by downloading the financial report as an +FDS code with the cell referencing.
In excel, cell refreshing is a way to refer to a cell in the formula.
What variable(s) is/are used in stack to keep track the position where a new item to be inserted or an item to be deleted from the stack
Answer:
Hence the answer is top and peek.
Explanation:
In a stack, we insert and delete an item from the top of the stack. So we use variables top, peek to stay track of the position.
The insertion operation is understood as push and deletion operation is understood as entering stack.
Hence the answer is top and peek.
