3 things in terms of photography to learn about.

Answers

Answer 1

The three important principle in photography are;

Light Subject and Composition.

What is the explanation for these terms?

Photography is about light. Without it, you couldn't even take images, let alone excellent ones.

The quality of light varies from one to photograph, yet it is always what gives your photographs their underlying structure. It doesn't get any more basic than that.

Most of us snap photos because something catches our attention.

Unsurprisingly, that "something" is your subject.

If you're explaining a photograph to someone else, the topic is most likely the first thing you'll mention.

Finally, the composition is the third and most important aspect of every shot.

Simply said, composition is the arrangement of the things in your shot. It includes your camera position, the connections between photo elements, and the things you accentuate, deemphasize, or altogether eliminate. Composition is the method through which you communicate your tale.

T/F a facade is a ""back-end"" object that is the single point of entry for the services of a subsystem.

Answers

False. A facade is a front-end object that provides a simplified interface for accessing the functionality of a subsystem. It is not a back-end object and is not necessarily a single point of entry.

A facade is a "front-end" object that provides a simplified interface to a more complex system or subsystem, making it easier to use and reducing the coupling between the subsystem and the rest of the application. It acts as a single point of entry for the services of the subsystem, but from the perspective of the client code that uses the facade, it appears to be a standalone object with a well-defined set of methods.

The purpose of a facade is to provide a simpler, more abstract interface to a complex system, which can help to improve the maintainability, extensibility, and testability of the code. By encapsulating the details of the underlying subsystem behind a facade, changes to the subsystem can be made without affecting the client code that uses it, as long as the facade interface remains unchanged.

False. A facade is a front-end object that offers a streamlined interface for getting at a subsystem's functionality. It does not have to be a single point of entry and is not a back-end entity.

A facade is a "front-end" object that offers a more user-friendly interface to a more complicated system or subsystem, hence decreasing the connection between the subsystem and the rest of the programme. Although it serves as a single point of access to the subsystem's services, the client code that uses the facade sees it as a stand-alone object with a clear set of methods.

The goal of a facade is to offer a more straightforward, abstract interface to a complicated system, which can enhance the code's testability, extensibility, and maintainability. Changes to the underlying subsystem can be made without impacting the client code that utilises it as long as the facade interface stays the same by enclosing the intricacies of the subsystem behind a facade.

A computer only has 2GB of RAM. Alicia says that virtual memory can be used instead of adding more RAM.

(i) Explain how virtual memory can compensate for the lack of RAM in Alicia's computer.

(ii) Explain why it would be beneficial for Alicia to get more RAM instead of relying on virtual memory.

Answers

Virtual memory is a technique that allows a computer to use its hard drive space as if it were extra RAM. When the computer runs out of available RAM, it moves some of the data from RAM to the hard drive, freeing up space in RAM for other processes. This process is called paging.

Virtual memory can compensate for the lack of RAM in Alicia's computer by allowing it to run more programs or processes than it would be able to with only 2GB of RAM. However, virtual memory is much slower than physical RAM, as data must be constantly moved back and forth between RAM and the hard drive. This can result in a noticeable decrease in performance for the computer, particularly if it is running multiple programs simultaneously or working with large files.

It would be beneficial for Alicia to get more RAM instead of relying solely on virtual memory for several reasons. Firstly, as mentioned earlier, virtual memory is much slower than physical RAM, which can result in decreased performance. Secondly, constantly paging data to and from the hard drive can cause additional wear and tear on the hard drive, potentially shortening its lifespan. Finally, having more physical RAM can allow for smoother multitasking and faster processing of large files, which can lead to increased productivity and a better overall computing experience.

Answer:

(i) Virtual memory is a technique used by computers to extend the available memory beyond the physical RAM installed in the computer. It does this by temporarily transferring data from the RAM to the hard disk, freeing up space in the RAM for other tasks. When an application needs data that has been moved to the hard disk, it is swapped back into the RAM. This process is done automatically by the operating system and is transparent to the user.

(ii) Virtual memory is a useful technique when a computer does not have enough RAM to run all the necessary programs at once, but it has some drawbacks. When the operating system has to swap data between the RAM and the hard disk, it can slow down the computer's performance. This is because accessing the hard disk is slower than accessing the RAM. In addition, relying on virtual memory too heavily can shorten the life of the hard disk. Therefore, it would be beneficial for Alicia to get more RAM instead of relying on virtual memory, as this would improve her computer's performance and reduce wear and tear on her hard disk.

the ________ protocol resolves the domain name amazon.com to an ip address.

Answers

The DNS (Domain Name System) protocol resolves the domain name amazon.com to an IP address.

The DNS is a hierarchical decentralized naming system that translates human-readable domain names, such as amazon.com, into IP addresses, which are used to locate and connect to web servers and other networked resources. The DNS works by maintaining a distributed database of domain name records and using a set of protocols to resolve queries for specific domain names to their corresponding IP addresses.

When a user types a domain name into their web browser or other networked application, the application sends a DNS query to a DNS resolver, which is typically provided by the user's internet service provider (ISP) or another third-party DNS service. The resolver then queries a hierarchy of DNS servers, starting with the root servers, to find the authoritative DNS server for the domain name in question. The authoritative server then returns the IP address associated with the domain name, allowing the application to establish a connection with the appropriate server or resource.

Threads are taken from front/back of waiting queue

Answers

The threads waiting to acquire a lock are typically taken from the front of the waiting queue.

When a thread tries to acquire a lock that is already held by another thread, it is blocked and added to the waiting queue for that lock. The waiting queue is typically implemented as a FIFO (first-in, first-out) queue, meaning that the first thread that was added to the queue is the first one that will be given the lock when it is released.

Once the lock is released by the thread that currently holds it, the operating system or the lock implementation will typically wake up the thread at the head of the waiting queue and give it the lock. This thread can then proceed to execute the critical section protected by the lock.

However, it's worth noting that some lock implementations may use a different queuing strategy, such as priority-based queuing or fair queuing, which may affect the order in which threads are taken from the waiting queue. In these cases, threads may be taken from the back of the waiting queue if they have higher priority or have been waiting for a longer time.

a natural monopoly exists when, over the relevant range, increasing the output level results in a lowera. total costb. average total costc. average variable costd. average fixed coste. marginal cost

Answers

A natural monopoly exists when, over the relevant range, increasing the output level results in a lower b: "average total cost".

This occurs when the fixed costs of producing the product are so high that it is not economically feasible for more than one firm to enter the market. As a result, the firm that is already producing the product has a significant cost advantage over any potential competitors. In this situation, the firm can produce the product at a lower cost per unit as it increases its output level.

This is because the fixed costs are spread out over a larger number of units, resulting in a lower average total cost. However, it is important to note that a natural monopoly may not necessarily result in lower prices or higher quality for consumers, as the monopolist may still have market power and may set prices and quality levels to maximize its own profits.

53. T F If a class doesn't have a copy constructor, the compiler generates a default copy constructor for it.

Answers

The given statement "If a class doesn't have a copy constructor, the compiler generates a default copy constructor for it" is true because the default copy constructor is a member function of a class that is automatically generated by the compiler.

The default copy constructor performs a shallow copy of the object's data members. It simply copies the values of all data members from the original object to the new object. However, there are some cases where a class may require a custom copy constructor to perform a deep copy of its data members. In such cases, the default copy constructor may not be sufficient.

For instance, if a class has a pointer as a data member, then a shallow copy of the pointer value will simply copy the address of the pointer rather than the value it points to. This may lead to unexpected behavior when the original object and the copied object modify the same data. In summary, the default copy constructor is a member function of a class that is automatically generated by the compiler if the class does not have its own copy constructor defined.

}
A. 5
B. 8
C. 10
D. 13
E. Error. Cannot make a new variable x inside function increase()

Answers

The output is 13. The function "increased()" does not affect the value of x outside of its scope, so x remains 10. Then x is incremented by 3, resulting in 13.

The code declares a variable "x" with a value of 10. It then calls the function "increase()", which is not defined in the code snippet, so it will throw an error. Assuming that the intended function is "increased()", this function declares a new variable "x" with a value of 5, but this variable is scoped only to the function and does not affect the value of "x" outside of it. Therefore, the value of "x" remains 10 when the function call returns, and then it is incremented by 3 with the line "x = x + 3". Finally, the value of "x" (13) is printed to the console with "console.log(x)".

A static function can only be called from within the same compilation unit (file). true or false

Answers

True. A static function is a function that is declared with the keyword "static" before the function name. This means that the function is only visible and accessible within the same compilation unit, which is essentially the same file that the function is defined in.

When a program is compiled, each source file is compiled into its own object file, which contains the compiled code for all of the functions and variables in that file. If a function is declared as static, it is not included in the symbol table that is generated for the object file, which means that it cannot be called from other source files or from outside the program.

Static functions are often used in C and C++ programming to encapsulate functionality within a single file or module. This helps to keep the code organized and reduces the risk of naming conflicts or unintended side effects. However, it also means that static functions cannot be reused or shared across different parts of the program.

In summary, a static function can only be called from within the same compilation unit or file where it is defined. This is because the function is not visible or accessible outside of that file due to its static declaration.

Each teacher has the assessment grades for each student. These grades are stored in numerical order.

(i) The grades for one student are shown:

2, 3, 4, 5, 6, 7, 8.

Show the steps that a binary search would take to check whether the student has achieved a grade 7 in any assessment.

Your answer must refer to the grades provided.

(ii) Explain how a binary search would determine that a value does not appear in a given array.

(iii) Give one advantage of a binary search over a linear search.

Answers

(i) To check whether the student has achieved a grade 7 in any assessment using binary search, the steps would be as follows:

1. Identify the middle value in the array of grades. In this case, the middle value is 5.

2. Compare the middle value to 7. Since 7 is greater than 5, we know that any grade 7 would be to the right of the middle value.

3. Discard the left half of the array, including the middle value.

4. Identify the new middle value in the remaining array. In this case, the middle value is 7.

5. Compare the middle value to 7. Since 7 is equal to 7, we know that the student has achieved a grade 7 in at least one assessment.

(ii) A binary search determines that a value does not appear in a given array by continuing to divide the array in half and checking the middle value until the value is found or until there are no more values to check. If the middle value is not the value being searched for, the search can discard the half of the array that does not contain the value and continue searching the other half. If the search reaches the end of the array without finding the value, it knows that the value is not in the array.

(iii) One advantage of a binary search over a linear search is that a binary search can be much faster for large arrays. A linear search must examine each element of the array in order until it finds the value being searched for, which can be time-consuming for large arrays. In contrast, a binary search can quickly discard large portions of the array and hone in on the value being searched for, making it much more efficient for large arrays.

True/False:With paging, you can run process when some pages are on disk

Answers

True.

The operating system splits a process's virtual address space into pages, which are predetermined little fixed-size blocks of memory. These pages are loaded into physical memory as needed; if not all of the pages needed by a process can fit in physical memory, some of them may be kept in a page file on disc.

A page fault happens when a process tries to access a page that is not already in physical memory. The operating system can then bring the needed page into memory from disc, possibly replacing another page, if this is necessary.

This means that as long as there is enough physical memory available to keep the set of pages that are now active, a process can continue to operate even if part of its pages are saved on disc.

However, since reading pages from the disc is much slower than accessing them from physical memory, a process' performance may suffer if it regularly has to access pages that are not in memory.

is a simple program that predicts what sides and beverages you may want with your order based on your previous orders and what other users have ordered an example of strong or weak ai? explain your answer.

Answers

A simple program that predicts what sides and beverages you may want with your order based on your previous orders and what other users have ordered is an example of weak AI. Weak AI, also known as narrow AI, is designed to perform specific tasks and does not possess general intelligence or self-awareness.

In this case, the program uses patterns from previous orders to make recommendations, which is a specific and limited task compared to the broader capabilities of strong AI.

The program you described, which predicts what sides and beverages a user may want with their order based on their previous orders and what other users have ordered, would be an example of weak AI. This is because it is programmed to perform a specific task and can only make predictions based on a limited set of data. Strong AI, on the other hand, would be capable of general intelligence and independent learning, similar to that of a human. While the program you described may use machine learning algorithms to improve its predictions over time, it still operates within a narrow range of capabilities and cannot perform tasks beyond its programmed parameters.

______ sockets and the ______ protocol are more desirable for the vast majority of Java programmers.

Answers

TCP (Transmission Control Protocol) sockets and the TCP protocol are more desirable for the vast majority of Java programmers, as they offer reliable, connection-oriented communication.

TCP (Transmission Control Protocol) is a network protocol used in computer networks to provide reliable and ordered delivery of data between devices. It operates at the transport layer of the OSI model and works in conjunction with the IP (Internet Protocol) to enable communication between devices over the internet. TCP ensures that data packets are delivered to the correct destination in the correct order and retransmits lost packets to ensure data integrity. It also provides flow control and congestion control mechanisms to manage network traffic and prevent network congestion. TCP is widely used in web browsing, email, file transfer, and other internet-based applications. It is a connection-oriented protocol, which means that a connection is established between devices before data is transmitted, and terminated when data transfer is complete.

saved what is the order of growth of the worst case running time of the put operation for the book's binary search with n keys, when the key being inserted is already in the symbol table? question 1 options: logarithmic constant linear quadratic

Answers

The order of growth of the worst-case running time for the put operation in a binary search with n keys, when the key being inserted is already in the symbol table, is logarithmic. This is because the algorithm only needs to traverse the height of the binary search tree, which is proportional to log(n) in the worst case.

The order of growth of the worst case running time of the put operation for the book's binary search with n keys, when the key being inserted is already in the symbol table, is constant. This is because the put operation will simply update the value associated with the existing key, rather than searching for the correct position to insert the key. Therefore, the time complexity of the put operation remains the same regardless of the number of keys in the symbol table.
