The earliest object-oriented version of the C language, called "C with Classes," was developed by Bjarne Stroustrup.
"C with Classes" was a precursor to the C++ programming language, which introduced the concept of classes and object-oriented programming features to the C language. Bjarne Stroustrup initially developed "C with Classes" as an extension to C to support the object-oriented programming paradigm. It included features such as classes, objects, inheritance, and polymorphism, laying the foundation for what would later become C++. The development of "C with Classes" eventually led to the creation of C++ as a full-fledged programming language, which gained significant popularity for its powerful object-oriented capabilities combined with the efficiency and flexibility of the C language.

what sets atm apart from ethernet is its ____ size.
What sets ATM apart from Ethernet is its "fixed" size.
ATM (Asynchronous Transfer Mode) and Ethernet are two different networking technologies with distinct characteristics. One of the key differences between ATM and Ethernet is the size of the data units they handle.
ATM uses fixed-size cells, where each cell is precisely 53 bytes in length, including both the header and the payload. This fixed size allows for efficient and predictable switching and routing within the network. The small cell size is suitable for carrying various types of traffic, including voice, video, and data, and it enables better quality of service (QoS) and traffic management capabilities.
In contrast, Ethernet uses variable-length packets, commonly referred to as frames. The size of Ethernet frames can vary from a minimum of 64 bytes to a maximum of 1,500 bytes (excluding VLAN tagging). Ethernet frames have a variable payload size and typically include additional overhead for addressing, error checking, and other control information.
The fixed size of ATM cells provides deterministic performance and efficient multiplexing of different traffic types, while Ethernet's variable frame size allows for more flexibility and scalability in accommodating different data loads.

when using fixed allocation dhcp, what's used to determine a computer's ip?
When using fixed allocation DHCP (Dynamic Host Configuration Protocol), the computer's IP address is determined based on the pre-configured assignment set by the network administrator.
In fixed allocation DHCP, the IP addresses are assigned to specific computers based on their unique identifiers, such as the Media Access Control (MAC) address of the network interface card. The network administrator manually associates a specific IP address with each computer's MAC address in the DHCP server configuration. When a computer requests an IP address from the DHCP server, it sends its MAC address as part of the request. The DHCP server checks its configuration and assigns the pre-defined IP address that corresponds to the MAC address of the requesting computer. This ensures that each computer consistently receives the same IP address every time it connects to the network. Fixed allocation DHCP is commonly used in situations where specific IP addresses need to be assigned to particular devices or where IP address management requires stricter control. It eliminates the need for dynamic IP address assignment and provides a reliable and consistent IP address assignment for individual computers.

9.3.4: disk scheduling algorithms. the r/w head of a disk is at track 143. the previous position was track 0. requests to access the following tracks have arrived:
In disk scheduling algorithms, the goal is to determine the order in which disk requests are serviced to minimize the seek time.
In this scenario, the read/write head of a disk is currently at track 143, and the previous position was track 0. There are requests to access various tracks. The solution will involve selecting a disk scheduling algorithm and determining the sequence in which the tracks should be accessed to minimize the seek time.
To minimize the seek time, various disk scheduling algorithms can be employed, such as FCFS (First-Come, First-Served), SSTF (Shortest Seek Time First), SCAN, C-SCAN, LOOK, or C-LOOK.
The choice of algorithm and resulting track sequence will depend on the specific requirements and constraints of the system. Each algorithm has its advantages and trade-offs.
For example, in the SSTF algorithm, the request with the shortest seek time to the current head position is selected next. This minimizes the distance traveled by the head and reduces the average seek time.
In the given scenario, the specific requests to access tracks are not provided. To determine the optimal sequence, the distances between the current position (track 143) and the requested tracks need to be considered. The algorithm selected and the resulting track sequence will ultimately determine the seek time in this disk scheduling problem.

In this code, class A is the superclass, and class B extends class A, inheriting its methods and variables. Class C extends class B, inheriting from both class A and class B.
In the main method of the "test" class, an object of class B named "myObject" is created using the constructor "new B()". When the method "firstMethod" is called on the "myObject" object with the input parameter of 2, the overridden version of the method in class C is invoked. This means that the implementation of the method in class C will be executed instead of the method in class A. In class C, the overridden "firstMethod" subtracts 2 from the input value.

a. she should save photos with a lossless compression algorithm, to ensure that the posters are of highest quality.
b. she should save the photos as jpeg photos, because only jpeg photos can be printed out. c. she should save the photos as black and white, as color photos can't be saved in full detail. d. she should take the photos using a real camera, as phone cameras can't save high resolution photos.
The advice that will help Cora the most in creating high-quality posters of her cat photos is to choose option A: she should save photos with a lossless compression algorithm to ensure the highest quality.
Saving photos with a lossless compression algorithm (option A) is the recommended choice for maintaining the highest quality of the images. Lossless compression algorithms, such as PNG or TIFF, preserve all the original details and colors of the image without any loss of quality. This is important when printing posters as it ensures the sharpness, clarity, and accuracy of the image.
Option B, saving the photos as JPEG, may result in some loss of quality due to the compression applied by the JPEG format. While JPEG is widely used for web and digital purposes, it may not be the best choice for high-quality printouts.
Option C suggests saving the photos as black and white, which limits the image to grayscale and eliminates the full color detail. If Cora wants to preserve the original colors and vibrancy of her cat photos, this option is not ideal.
Option D suggests using a real camera instead of a phone camera to capture high-resolution photos. While using a dedicated camera can offer advantages in terms of image quality, it is not the most crucial factor in creating high-quality posters.

which of the following is a valid reference count for an object that is being referenced? group of answer choices 2.5 3.0 0 1
A valid reference count for an object being referenced cannot be 2.5 or 3.0, as reference counts are typically whole numbers. A reference count of 0 indicates that there are no active references to the object, while a count of 1 suggests that there is exactly one reference to the object.
In programming, reference counting is a technique used to manage memory allocation and deallocation. It involves keeping track of the number of references to an object. When the reference count reaches 0, it indicates that there are no active references to the object, and it can be safely deallocated from memory.
A reference count is usually an integer value, representing the number of references to the object. It cannot be a fractional value such as 2.5 or 3.0 since it is a count of discrete references. It is either a whole number or zero.
A reference count of 0 implies that there are no active references to the object. This suggests that the object is no longer being used and can be safely deallocated. On the other hand, a reference count of 1 indicates that there is exactly one reference to the object. In this case, the object is still being referenced and should not be deallocated as it is still in use.
To summarize, a valid reference count for an object being referenced is either 0 (indicating no active references) or 1 (representing a single reference). Fractional values such as 2.5 or 3.0 are not valid in the context of reference counting as they do not accurately represent the number of references to an object.

The amount of data communicated between the host and the DNS server is very limited, there is no need for flow and congestion control, as well as for connection setup and tear down. Furthermore, the lack of reliability of UDP is not a problem, because if there is no answer, the request is simply repeated after timeout.
The resolver procedure contacts a local DNS server via UDP instead of TCP for several reasons. Firstly, UDP inherently supports DNS lookup by providing a field for this purpose in the segment header.
Secondly, UDP makes real-time communication possible, which is ideal for cases where the host also wants to send or receive more data, such as a multimedia file. However, the primary reason why UDP is preferred is that the amount of data communicated between the host and the DNS server is very limited.
As a result, there is no need for flow and congestion control, connection setup, and tear down.

The worst-case time complexity of a "findmin" function on a balanced binary search tree would be O(log n).
This is because in a balanced binary search tree, each node has at most two children and the left subtree of any node contains only values that are less than the node's value. Therefore, the minimum value in the tree is located at the leftmost node.
When searching for the minimum value using the "findmin" function, we start at the root node and recursively move to the left child of each node until we reach a leaf node. Since the tree is balanced, the height of the tree is log n, where n is the number of nodes in the tree. Therefore, the worst-case time complexity of the "findmin" function is O(log n).

which tcp/ip configuration parameter identifies the router that is used to reach
Answer:
The default gateway is the TCP/IP configuration parameter that identifies the router used to reach other networks.
Explaination:
In TCP/IP networking, the default gateway is a crucial configuration parameter that specifies the IP address of the router or gateway device that connects your local network to external networks, such as the internet. It serves as the next-hop destination for all traffic that is destined for networks outside of the local network.
When a device needs to communicate with a network outside of its own subnet, it checks its routing table to determine the appropriate next hop. The default gateway entry in the routing table specifies the IP address of the router that should be used as the next hop for forwarding the traffic. The router then takes care of routing the packets to their final destination.
Setting the default gateway correctly is essential for proper network connectivity. Without a valid default gateway configuration, devices on the local network would be unable to reach external netwoor access the internet.
The default gateway parameter is typically configured on each device individually, such as computers, servers, or network switches. It can be set manually by the network administrator or obtained automatically through DHCP (Dynamic Host Configuration Protocol) if the network supports it. The router's IP address specified as the default gateway must be reachable from the local network to ensure proper routing of traffic.
In summary, the default gateway is the TCP/IP configuration parameter that identifies the router used to reach other networks. It plays a critical role in determining the path of network traffic from the local network to external networks, facilitating effective communication and connectivity.
