functional programming excels at 'transactional' programming where a specific desired outcome is required for specific parameters. group of answer choices true false

Answers

True. Functional programming is well-suited for transactional programming, where a specific desired outcome is required for specific parameters.

This is because functional programming emphasizes immutability and the use of pure functions, which means that the output of a function is solely dependent on its inputs, and it does not have any side effects or rely on external state.

In transactional programming, it is important to ensure that a set of operations are completed together in a consistent manner, or else they should be rolled back entirely. Functional programming supports this by providing tools such as higher-order functions and monads, which allow for the composition of smaller, reusable functions into larger, more complex programs.

Furthermore, the use of pure functions in functional programming makes it easier to reason about the correctness of a program and to debug it, since there are fewer sources of potential errors or bugs.

In contrast, imperative programming, which emphasizes mutable state and side effects, can be more error-prone and harder to debug. Overall, the transactional nature of functional programming, along with its focus on immutability and pure functions, makes it a powerful tool for building reliable and robust systems that require specific outcomes for specific parameters.

when you take a photo using your smartphone, what kind of data is the photo?

Answers

Answer:

Explanation:

output

A photo taken with a smartphone is digital image data, typically in the form of a JPEG or PNG file format. It is created by converting light information into numerical values representing colors and intensities.

When you capture a photo using your smartphone, the device's camera lens focuses light onto an image sensor, which consists of millions of tiny light-sensitive elements called pixels. Each pixel detects the intensity and color of the light that falls on it. This information is then converted into an electrical signal by the sensor, which sends the data to the smartphone's image processor.

The image processor analyzes and interprets the data, applying various adjustments such as white balance, exposure, and color correction to produce a visually appealing image. It also compresses the image data to reduce file size, using a common format like JPEG or PNG. JPEG is a lossy compression format, meaning some image quality is sacrificed for smaller file sizes, while PNG is a lossless format that preserves image quality at the cost of larger file sizes.

Once the image processor has finished processing the data, it saves the final image as a file in the device's storage. This digital image file contains a series of numerical values that represent the colors and intensities of each pixel in the image. When the image is viewed on a screen, these values are used to recreate the original scene captured by the camera, allowing you to see the photo.

In summary, a photo taken with a smartphone is digital image data that has been processed and compressed into a specific file format, containing numerical values representing the colors and intensities of each pixel in the image.

mike has just been hired as a junior technician and wants to know which device works at the data link layer of the osi model and can be configured to support multiple broadcast domains. what do you tell him?

Answers

You can tell Mike that a switch is a device that works at the data link layer of the OSI model and can be configured to support multiple broadcast domains.

Switches are network devices that connect devices together on a local area network (LAN) and operate at the data link layer of the OSI model. They are designed to forward and filter data frames between network segments based on the MAC (Media Access Control) addresses of the devices connected to them.

By default, switches forward broadcast traffic to all connected devices within the same broadcast domain. However, switches can be configured to support multiple broadcast domains, which can help to improve network performance by reducing unnecessary broadcast traffic. This is typically done by using VLANs (Virtual Local Area Networks) to segment the network into multiple broadcast domains, allowing the switch to selectively forward broadcast traffic only to the devices within the same VLAN.

Dynamic programming is an algorithmic technique that solves complex problems by breaking them down into simpler subproblems and storing their solutions for efficient computation.

The given C program calculates the Levenshtein distance between two given words using dynamic programming. To convert it to x86 Intel assembly code manually, we need to follow the logic of the program and implement it using assembly instructions.

First, we need to include the necessary header files like stdio.h, string.h, and stdlib.h. Then, we define the required functions like min, swap, and editDist as done in the C program.

To initialize the distances, we need to allocate memory for oldDist and curDist using the malloc function and multiply the size of each by the word2_len + 1. This can be done using the lea instruction to calculate the memory addresses and mov instruction to allocate memory.

Then, we need to implement the nested for loop using the cmp and jne instructions to check if the characters are the same or not and then implement the operations of deletion, insertion, and substitution as done in the C program. The swap function can be implemented using the xchg instruction.

Finally, we need to return the distance and free the allocated memory.

The main function can be implemented to take input from the command line arguments and print the output using the printf function.

Overall, the assembly code will be complex and lengthy as compared to the C program but will follow the same logic and sequence of instructions.

(a) (6 point) First, write a predicate path_2(A,B) which holds if there is path of length two from A to B. The path is allowed to have duplicate cities. For example: ?- path_2(new_york,B). boston ; dallas I ?- path_2(A, dallas). san_diego; new-york ; false.

Answers

To write the predicate path_2(A,B), we can make use of the link(A,C) and link(C,B) predicates to check if there exists a city C such that there is a direct link from A to C and a direct link from C to B.

Here's the Prolog code for the predicate:

path_2(A,B) :-

   link(A,C),

   link(C,B).

This code defines the path_2 predicate which takes two arguments A and B. The predicate first checks if there exists a city C such that there is a link from A to C using the link(A,C) predicate. If such a link exists, the predicate then checks if there is a link from C to B using the link(C,B) predicate. If such a link exists, then path_2(A,B) holds true.

To test this predicate, we can use queries like ?- path_2(new_york,B). which will find all cities B that are reachable from New York by a path of length 2. Similarly, we can use queries like ?- path_2(A, dallas). to find all cities A that have a path of length 2 to Dallas.

Over time, the rabbit learns to associate the CS with the US and eventually, the CS alone is sufficient to elicit the CR, which is a blink of the eye.

The CR is a reflexive response that is controlled by the cerebellum and other brain regions involved in motor control. Eyeblink conditioning is a widely studied form of classical conditioning that has been used to investigate the neural mechanisms of learning and memory.

we have three tables: tblproduct, tblproductsubtype, and tblproducttype. we have a foreign key in tblproduct table that references the primary key of the tblproductsubtype table and a foreign key in the tblproductsubtype table that references the primary key of the tblproducttype table. what is the correct order to drop the tables successfully using the statement drop table the table name?

Answers

To successfully drop the tables with foreign keys, we need to drop the child tables before the parent tables. Therefore, the correct order to drop the tables is:

1. Drop the child table `tblproduct` which has the foreign key reference to the `tblproductsubtype` table.

```

DROP TABLE tblproduct;

```

2. Drop the `tblproductsubtype` table, which has the foreign key reference to the `tblproducttype` table.

```

DROP TABLE tblproductsubtype;

```

3. Finally, drop the parent table `tblproducttype`.

```

DROP TABLE tblproducttype;

```

By following this order, we ensure that there are no dependencies between the tables at the time of dropping them.

What fact constitutes the main difference between most standard fault types and issues of network performance?Standard faults usually result from performance issues.Performance management has its own set of tasks.Performance management is a subset of fault management.Standard faults usually result from failed devices.

Answers

A standard fault is a type of fault that occurs due to a deviation from a predefined specification or standard, which can cause errors or malfunctions in a system or process.

The main difference between most standard fault types and issues of network performance is that standard faults usually result from failed devices, whereas issues of network performance are caused by various factors that impact the network's ability to perform optimally.

Standard faults are typically straightforward to identify, and they involve the replacement or repair of a faulty device. For instance, if a router stops working, it is usually a standard fault, and the technician can easily replace it to restore the network's functionality. In contrast, issues of network performance are complex, and they require a more comprehensive approach to resolve.

Performance management is a subset of fault management that focuses on optimizing the network's performance, monitoring, and analyzing data to identify potential bottlenecks, and resolving them before they affect the network's performance. Unlike standard faults that are typically caused by a single failed device, issues of network performance could result from various factors such as bandwidth limitations, network congestion, or poor routing configurations.

Therefore, performance management requires a different set of tasks than fault management, and it involves continuously monitoring and analyzing the network's performance to identify potential performance issues and resolve them proactively. Overall, understanding the difference between standard faults and network performance issues is critical for network administrators to manage their networks effectively and optimize their performance.

consider a short link, over which a sender can transmit at a rate of 200 bits/sec in both directions (meanwhile the propagation delay is so small that we are omitting it in this question). suppose that packets containing data are 100,000 bits long, and packets containing only control (e.g., ack or hand-shaking) are 200 bits long. assume that n parallel connections each get 1/n of the link bandwidth. now consider the http protocol, and suppose that each downloaded object is 100 kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. would parallel downloads via parallel instances of non-persistent http make sense in this case? now consider persistent http. do you expect significant gains over the non-persistent case? justify and explain your answer.

Answers

For this scenario, the available bandwidth is 200 bits/sec and the packet size for data is 100,000 bits, whereas the packet size for control is 200 bits.

Therefore, the time required to transmit a data packet over the link is 500 seconds, whereas the time required to transmit a control packet is 1 second. In this case, if n parallel connections are established, each connection would get a bandwidth of 200/n bits/sec.

For non-persistent HTTP, each downloaded object requires a separate connection to be established, and since each connection gets only 1/n of the available bandwidth, the overall download time for 10 objects would be (10 x 500)/n seconds. Therefore, parallel downloads via parallel instances of non-persistent HTTP do not make sense in this case, as the overall download time would be longer compared to downloading all the objects sequentially via a single connection.

On the other hand, for persistent HTTP, the same connection can be used to download multiple objects. Therefore, the overhead of establishing a new connection for each object can be avoided, and the overall download time would be reduced. Hence, significant gains are expected over the non-persistent case when using persistent HTTP for downloading multiple objects from the same sender.
