By utilising the idea of normalisation, a "base" (or database) in a database enables you to store only one version of the data.
Database design uses the normalisation process to reduce redundancy and enhance data integrity. It entails decomposing a database into smaller, more manageable tables and creating connections among them. Each item of data is therefore kept in a single location, and all references to that data are made of that location alone. This makes the database more effective and simpler to administer by reducing data redundancy and enhancing data consistency. There are different levels of normalisation, and each has its own specifications on how to arrange data. The end result of normalising is to produce a database that is dependable and simple to use, resulting in more consistent and efficient data administration.

A landline voice telephone call is an example of a circuit-switched network connection, as opposed to a packet-switched network connection.
What is circuit-switched network?Circuit switching is a method of communication in which a dedicated, secure connection (or circuit) is established between two points on a network for the duration of the communication.
In this form of communication, a connection is created between two points in a network, allowing the two devices to exchange information. The connection is maintained throughout the duration of the communication, and data is transmitted via a dedicated communication path.
A landline voice telephone call is an example of a circuit-switched network connection because it establishes a dedicated, secure connection between two points (the caller and the receiver) for the duration of the call.
Packets of data do not need to be routed through a network and assembled at the receiving end since the connection is established in advance. In contrast to circuit switching, packet switching networks use packet switching technology to transmit data.

1. Write a program in assembly language that divides the screen into two equal horizontal colors using BIOS services. The colors of the upper and lower halves should be black and magenta respectively.
2. Print your ID at the center of the lower half. All the text in the lower half should blink except the ID.
ID is BC123456789
3. Print star characters in the upper half using loops; first incrementing from one to five and then decrementing from five to one
1) To write a program in assembly language that divides the screen into two equal horizontal colors using BIOS services, 2) To print your ID at the center of the lower half, and 3) to print star characters in the upper half using loops you can use the INT 10h BIOS service.
1-To write a program in assembly language that divides the screen into two equal horizontal colors using BIOS services, you can use the INT 10h BIOS service. You will need to use the AH=0Ch function to set the video mode to a mode that supports dividing the screen into two halves. Then, you can use the AH=10h function to set the color of the upper and lower halves of the screen. For example, to set the upper half to black and the lower half to magenta, you can use AH=10h, AL=06h, BH=00h, BL=00h, CX=00h, and DX=0Fh. This will set the color of the upper half to black and the lower half to magenta.
2-To print your ID at the center of the lower half, you can use the INT 10h BIOS service to set the cursor position to the center of the lower half of the screen. Then, you can use the BIOS services to print your ID at that position. To make all the text in the lower half blink except the ID, you can use the AH=10h function with the BL=08h parameter to enable blinking. You can then disable blinking for the ID by using the AH=10h function with the BL=07h parameter.
3-To print star characters in the upper half using loops, you can use the INT 10h BIOS service to set the cursor position to the upper left corner of the screen. Then, you can use nested loops to print stars in the upper half. To print stars first incrementing from one to five and then decrementing from five to one, you can use nested loops with different step values.

Pascal was designed to encourage good programming practices using structured programming and data structuring. Pascal was initially designed to teach programming, and it quickly became a popular programming language because of its simplicity and ease of use.
Pascal was also widely used for scientific research, engineering, and business applications. Pascal was developed to improve on the shortcomings of the earlier programming languages like FORTRAN and COBOL. It was developed with a focus on simplicity and readability. Pascal features, including data structuring, data types, and syntax, allowed the creation of reusable and scalable software.
Why is Pascal important?
Pascal is important because it was one of the first programming languages that used procedural programming, which means that programs are divided into reusable and smaller subroutines. It is still used today, although it has been largely replaced by other programming languages, like C++. Pascal's impact can still be seen in modern programming languages, including Java, Python, and C++. Pascal has influenced many languages in a variety of ways.

The available fiber-optic cable in the market was an SMF cable. Analyze and discuss which of the following fiber Ethernet standards he should follow under such circumstances.
a. 100BASE-SX
b. 1000BASE-SX
c. 1000BASE-LX
d. 100BASE-FX
Mr. Anderson should follow the b) 1000BASE-LX fiber Ethernet standard in this scenario.
The 1000BASE-LX standard supports data transmission at 1000 Mbps and can cover distances of up to 10 km with single-mode fiber (SMF) cable, which is suitable for the 2000 m distance requirement.
The 100BASE-SX and 100BASE-FX standards are designed for slower data transmission rates of 100 Mbps and operate over multimode fiber (MMF) cables with shorter transmission distances, making them unsuitable for this scenario.
The 1000BASE-SX standard also operates over MMF cables, which may not be able to support the necessary distance of 2000 m. Therefore, 1000BASE-LX is the most appropriate standard for this Ethernet network segment setup.

Highest Values in List Write a function called highest_values that accepts as arguments a list of numeric values and a single integer (n). The function should return a list made up of the largest n values from the argument list in order from lowest to highest. For example, if the argument list is [46, 82, 25, 61, 70, 33, 54] and n is 3, the return value should be [61, 70, 82]. Assume that the argument list contains at least n elements.
Here's a possible implementation of the highest_values function in Python:
def highest_values(values, n):
sorted_values = sorted(values)
return sorted_values[-n:]
How does the above function work?The function first sorts the input list of values using the sorted function, which returns a new sorted list without modifying the original one.
Then, it selects the last n elements of the sorted list using the slicing syntax [-n:], which returns a new list containing only the last n elements of the original list.
This should output [61, 70, 82], which are the three highest values in the input list [46, 82, 25, 61, 70, 33, 54] sorted in ascending order.

When the loop terminates, result should hold the product of the odd numbers between 10 and 20. Just write the for loop header; do not write the loop body itself.
No other homework question I have is like this one, I've gotten the rest of them right so far. But for hints I keep getting that "you should consider using a comma".
The for loop header in C++ that iterates the loop from the values 10 to 20 is as follows:for (int i = 10; i <= 20; i++) { }
Note that the loop starts at 10 and ends at 20.
Let's discuss more below.
As soon as the loop initializes, the integer i is equal to 10. It then compares i to 20 in the loop header to see if it should terminate. If i is less than or equal to 20, the loop body is executed. The loop header's final expression (i++) increments i by one after each iteration to prepare for the next iteration.Here is how the loop body should be completed:
result = result * i;
This line will set the result equal to the product of the current value of i and the current value of result.

1 ptUsers are complaining that they are unable to browse certain websites on the Internet. An administrator can successfully ping a web server via its IP address, but cannot browse to the domain name of the website. Which troubleshooting tool would be most useful in determining where the problem is?netstattracertnslookupipconfig
Answer:
"nslookup" is the best troubleshooting tool to use in this situation to figure out where the problem is.
Nslookup is a command-line tool that can be used to ask DNS (Domain Name System) servers for information about how a domain name maps to an IP address. In this case, the administrator can ping a web server using its IP address, but he or she can't go to the website's domain name. This means that there might be a problem with the way DNS resolves that domain name.
The administrator can use nslookup to ask the DNS server if the domain name resolves to the right IP address. If the domain name doesn't resolve right, it could mean that there is a problem with the DNS server or with the DNS records for the domain name.
So, nslookup can help the administrator figure out if the problem is related to DNS or not. If it is, it can help narrow down the problem if it is related to DNS.
