Suppose within your Web browser you click on a link to obtain a Web page, and the Web page is consisting of one HTML text with eight referenced objects. Let RTT0 denote the RTT between the local host and the server containing the object, the link transmission bandwidth is R, and the HTML text file size is L0 and the reference objects have a size of L1, L2, L3, …, L8, respectively. How much time elapses from when the client clicks on the link until the client receives the object in the following scenarios?
a. Non-persistent HTTP with no parallel TCP connections?
b. Non-persistent HTTP with the browser configured for 9 parallel connections?
c. Persistent HTTP with no parallel TCP connection?
d. Persistent HTTP with the browser configured for 9 parallel connections?

Answers

Answer 1

The time elapse from when the client clicks on the link until the client receives the object for

a. Non-persistent HTTP with no parallel TCP connections is calculated as follows:

The time required for the request to reach the server = RTT0

The time required to get the response from the server = RTT0

The time required to get the HTML text file to the client = L0/R

The time required to get the objects one-by-one to the client is = 8(RTT0 + L1/R + RTT0 + L2/R + RTT0 + L3/R + … + RTT0 + L8/R)= 8(RTT0 + L1 + L2 + L3 + … + L8)/R + 8RTT0

Therefore, the total time taken to get the object is:2RTT0 + L0/R + 8(RTT0 + L1 + L2 + L3 + … + L8)/R + 8RTT0= 2RTT0 + L0/R + 16RTT0 + (8/ R) * (L1 + L2 + L3 + … + L8)

Here, the first term denotes the time taken to establish a TCP connection with the server and to get the HTTP request from the client to the server, and the last term denotes the time taken to get the response for the HTTP requests from the server to the client.

b. Non-persistent HTTP with the browser configured for 9 parallel connections: The time elapse from when the client clicks on the link until the client receives the object for Non-persistent HTTP with the browser configured for 9 parallel connections is calculated as follows:

Each request has the following components: 2RTT0 (to establish the TCP connection and to send the HTTP request), L/R (to download the HTML file), and RTT0 (to receive the object from the server).

Now, we can only have a maximum of 6 objects at a time (parallel connections are limited to 6) being downloaded. Therefore, the time required for 9 objects is 2RTT0 + L0/R + (6 * RTT0) + 2RTT0 + L1/R + (6 * RTT0) + 2RTT0 + L2/R + (6 * RTT0) + 2RTT0 + L3/R + (6 * RTT0) + 2RTT0 + L4/R + (6 * RTT0) + 2RTT0 + L5/R + (6 * RTT0) + 2RTT0 + L6/R + (6 * RTT0) + 2RTT0 + L7/R + (6 * RTT0) + 2RTT0 + L8/R + (6 * RTT0) = 2RTT0 + L0/R + 6 * (2RTT0 + L1/R + L2/R + L3/R + L4/R + L5/R + L6/R + L7/R + L8/R)) = 2RTT0 + L0/R + 12RTT0 + 6(L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8)/R

Therefore, the total time taken to get the object is: 14RTT0 + L0/R + (6/R) * (L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8)

c. Persistent HTTP with no parallel TCP connection: The time elapse from when the client clicks on the link until the client receives the object for Persistent HTTP with no parallel TCP connection is calculated as follows:

For each request, we have the following components: 1RTT0 (to establish the TCP connection and to send the HTTP request), L/R (to download the HTML file), and 0 (to download the object as the object is cached by the client).

The time required for 9 objects is1RTT0 + L0/R + 0 + 1RTT0 + L1/R + 0 + 1RTT0 + L2/R + 0 + 1RTT0 + L3/R + 0 + 1RTT0 + L4/R + 0 + 1RTT0 + L5/R + 0 + 1RTT0 + L6/R + 0 + 1RTT0 + L7/R + 0 + 1RTT0 + L8/R + 0 = L0/R + L1/R + L2/R + L3/R + L4/R + L5/R + L6/R + L7/R + L8/R + 9RTT0

Therefore, the total time taken to get the object is: L0/R + L1/R + L2/R + L3/R + L4/R + L5/R + L6/R + L7/R + L8/R + 9RTT0d.

d. Persistent HTTP with the browser configured for 9 parallel connections : The time elapse from when the client clicks on the link until the client receives the object for Persistent HTTP with the browser configured for 9 parallel connections is calculated as follows:

For each request, we have the following components:1RTT0 (to establish the TCP connection and to send the HTTP request), L/R (to download the HTML file), and 0 (to download the object as the object is cached by the client).

Therefore, the total time required for 9 objects is L0/R + 0 + L1/R + 0 + L2/R + 0 + L3/R + 0 + L4/R + 0 + L5/R + 0 + L6/R + 0 + L7/R + 0 + L8/R + 0 + 9RTT0 = L0/R + L1/R + L2/R + L3/R + L4/R + L5/R + L6/R + L7/R + L8/R + 9RTT0.

Is a Trojan a malicious program that uses a computer network to replicate?

Answers

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.

when describing blocks of ip addresses, what does cidr do?

Answers

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.

in continuous data protection technology, which factor determines how far back the recovery points can go?

Answers

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.

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.

According to the question of RGB, the solution of the program is given below:

What is RGB?

RGB stands for Red, Green, and Blue. It is a system of three colors that is used in digital images and video, as well as in print publishing, to create a wide array of colors. The three colors are combined in various proportions to create different shades and hues. RGB is an additive system, meaning that when the three colors are combined at full intensity, they create white. When the colors are mixed in equal parts, they create gray.

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).

What information is used by TCP to reassemble and reorder received segments?a. port numbersb. sequence numbersc. acknowledgment numbersd. fragment numbers

Answers

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.

Final answer:

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.

The Invasion of the LionfishWhat was once just an attractive aquarium fish has recently become one of the biggest menaces in the Atlantic. The lionfish was accidentally introduced into the Atlantic Ocean in the 1990s. Because it has no natural predators, it has adapted quickly to its new home. The lionfish now threatens to destroy native fish populations in the Atlantic, Caribbean, and Gulf of Mexico.The lionfish spreads quite rapidly. Lionfish spread faster than any other invading species. Experts have called the invasion in the Atlantic the worst marine invasion of all time. The lionfish's success comes from an ability to reproduce all year round. In addition, they are greedy eaters with a fondness for small fish and crustaceans. They will eat anything smaller than they are. Lionfish love the warm waters of the Gulf of Mexico. Since their first sighting, they have rapidly multiplied. In some locations, scientists estimate that lionfish populations exploded by 700 percent between 2004 and 2008 alone.To combat the invasion, wildlife agencies have sponsored lionfish derbies. In these derbies, local scuba divers are invited to harvest lionfish. In addition, many states offer recipes for preparing and eating lionfish to encourage harvesting. Lionfish have to be handled carefully because of their venomous spines, but they are apparently delicious. Increasing the harvest of lionfish will help. However, scientists estimate that more than a quarter of the population would have to be taken every month to stop the growing population.The lionfish has targeted our most fragile and important ecosystems.
