What information is used by TCP to reassemble and reorder received segments?a. port numbersb. sequence numbersc. acknowledgment numbersd. fragment numbers
Answer:
Sequence numbers is the right answer.
The Transmission Control Protocol (TCP) uses sequence numbers to put back together and change the order of the segments it has received. When a sender sends data over a TCP connection, it breaks the data up into smaller pieces and gives each piece a sequence number. Then, the receiver uses these sequence numbers to put the segments back in the right order and put the data back together.
TCP uses port numbers (choice a) to figure out which application is sending or receiving the data. But they are not used to put the segments back together or in a different order.
TCP uses acknowledgement numbers (choice c) to make sure that data has been successfully sent and received. They are not used to put the segments back together or change their order.
In IP (Internet Protocol), fragment numbers (choice d) are used to break up large packets into smaller pieces that can be sent over a network. TCP, on the other hand, works at a higher level of the networking stack and doesn't care about fragment numbers.
TCP uses sequence numbers to reassemble and reorder received segments. Port numbers, acknowledgment numbers, and fragment numbers are used in TCP, but not specifically for the reassembly and ordering of segments.
Explanation:The Transmission Control Protocol (TCP) uses sequence numbers to reassemble and reorder received segments. When a TCP segment is transmitted, it is numbered with a sequence number, which the receiving system uses to reassemble the data stream in the correct order. Even if the segments arrive out of order, the TCP stack on the receiving end can use these sequence numbers to put them back together correctly.
Port, acknowledgment, and fragment numbers are used in TCP, but not specifically for the reassembly and ordering of segments. Port numbers are utilized for multiplexing and demultiplexing data between the sender and receiver. Acknowledgment numbers are used to confirm the receipt of data, and fragment numbers are not a concept of TCP at all, but rather, they are used in the IP (Internet Protocol) layer when segments are too large and need to be fragmented for transport.

functional programming excels at 'transactional' programming where a specific desired outcome is required for specific parameters. T/F
The statement "Functional programming excels at "transactional" programming where a specific desired outcome is required for specific parameters" is true.
In functional programming, programs are treated as a set of mathematical functions, and the output of these functions is determined by the input given. When a set of inputs is given, the function's output is calculated, and the function doesn't have any external effects in the environment where it is called. It means that functional programming is suitable for developing programs that operate under transactional constraints, such as financial or e-commerce transactions.
Among the benefits of functional programming are referential transparency, which means that the same input will always produce the same output, regardless of where it is used. It's also easier to debug because the functions are pure, so there is no hidden state. Additionally, functional programs are simple to test and parallelize because they don't rely on mutable states or global variables. Thus, we can conclude that the given statement is true, i.e., functional programming excels at "transactional" programming where a specific desired outcome is required for specific parameters.

in continuous data protection technology, which factor determines how far back the recovery points can go?
In continuous data protection (CDP) technology, the factor that determines how far back the recovery points can go is the retention period.
Retention period refers to the amount of time that a CDP system retains the historical data changes that have been captured. The retention period determines how far back in time a system can go to recover data. For example, if the retention period is set to 7 days, the CDP system can provide recovery points up to 7 days back in time.
The retention period is typically configured by the system administrator or the organization's IT policies. The retention period may vary depending on the organization's needs, compliance requirements, and the resources available to support the storage and management of the historical data changes.
It's worth noting that the retention period can also affect the performance and storage requirements of a CDP system. A longer retention period may require more storage space and may impact system performance, while a shorter retention period may limit the availability of recovery points.
Therefore, the retention period should be carefully chosen to balance the organization's data protection needs and available resources.

What are the 4 most common types of data? (Give an example of each and explain when and why you might use them)
The information is primarily divided into four categories:
Nominal data.Regular data.Separate data.Constant data.What is Nominal data?Nominal data is a subset of qualitative data that categorizes variables. You can think of these categories as nouns or labels because they are merely descriptive, lack any quantitative or numerical significance, and cannot be arranged in any form of useful order or hierarchy. Variables without a quantitative value are labeled using nominal data. Male/female, hair color, countries, names of people, and others are typical examples—although they are a little out of date. Basically, they're labels, to put it plainly (and nominal comes from "name" to help you remember). In contrast to a collection of non-parametric ordered variables known as ordinal data, nominal data are a collection of non-parametric variables.To learn more about Nominal data, refer to:

What is a Digital Audio?The technique used to represent audio in digital form is known as digital audio. When an analogue audio signal is transformed into electrical signals—"on/off" pulses—rather than electromechanical signals, the digital audio chain is initiated. The signal is then further encoded to guard against any faults that might happen during signal transmission or storage. The "channel coding" is necessary for the digital system to reconstruct the analogue signal when it is replayed. Eight to Fourteen Bit Modulation, a channel code used in audio Compact Discs, is an illustration.With a specific sampling rate and bit resolution, an analogue signal is transformed into a digital signal that may have many channels (2 channels for stereo or more for surround sound).

abstraction, when done well, doesn't create vague code. rather, it gives clearer semantics and allows the programmer to be more precise. True or false
The statement abstraction, when done well, doesn't create vague code. rather, it gives clearer semantics and allows the programmer to be more precise is true.
Abstraction is the process of reducing complexity by creating a simplified model of a more complex system. This model can be used to understand the system, make predictions about its behavior, and make decisions about how to interact with it. It is also used to hide complexity from the user by providing a simplified interface to a more complex system.
When abstraction is done well, it doesn't create vague code. Rather, it gives clearer semantics and allows the programmer to be more precise. This is because abstraction allows the programmer to focus on the important details of a system and ignore the irrelevant ones. By ignoring the irrelevant details, the programmer can create simpler and more efficient code that is easier to understand and maintain.
Overall, abstraction is an essential concept in computer science that allows us to create simpler and more efficient systems.

Is a Trojan a malicious program that uses a computer network to replicate?
A Trojan is a malicious program that disguises itself as harmless or useful software. It is capable of causing significant harm to the infected computer, network, or device. Trojans may take various forms, such as ransomware, spyware, or adware, and may steal or damage information.
Although Trojans can be used to replicate themselves, they do not spread by themselves. Instead, they are usually spread through social engineering tactics, such as phishing emails, fake websites, or infected software downloads. Trojans can infect computers, networks, and devices without the user's knowledge and can often remain undetected for long periods.
Once a Trojan has infected a system, it can cause a variety of malicious activities, including:
Installing additional malware or viruses
Collecting sensitive information, such as passwords or banking details
Stealing personal or confidential data
Encrypting files or locking the user out of the system
Remote access to the system or network
Creating a backdoor into the system for future attacks
To protect against Trojans, it is essential to use reputable antivirus software and firewalls. Users should also exercise caution when opening email attachments, clicking on links, or downloading software from unknown sources. Finally, regular updates and patches to operating systems and software are crucial in preventing Trojan infections.

when describing blocks of ip addresses, what does cidr do?
Classless inter-domain routing is known as CIDR. It is an approach to IP address distribution and packet routing. An IP address's network prefix is specified via CIDR.
CIDR (Classless Inter-Domain Routing) is a more effective and adaptable method of allocating and routing Internet Protocol (IP) packets than the conventional IP address classes. A variable-length subnet mask (VLSM) is used by CIDR to distribute IP addresses, enabling more accurate distribution and greater address space use. Routing is made easier and subnets may be easily created thanks to the CIDR notation, which specifies the amount of bits in the network portion of the address. Internet Service Providers (ISPs) and network administrators manage IP addresses and routing tables using CIDR, which has evolved into the industry standard for IP address allocation and routing.
