Clarifying customer requirements and methodically arranging them in a specification document are the objectives of the requirements analysis and specification phase.
The Requirements Analysis Phase's goal is to turn the needs and high-level requirements defined in prior phases into requirements that are clear, complete, consistent, traceable, and approved by all relevant stakeholders. You choose the software's foundation during the requirements phase. Without it, your development team would be unable to do any of its duties because it instructs them on what to do. This stage can establish the behavior and constraints of the system. The second significant development phase of the overall process is represented by the activity of system requirements analysis.

Answer: The correct answer is an option (E) calls the constructor as defined in the current class'parent class
I hope this helps you!<3
Explanation:
E) The instruction super( ); calls the constructor as defined in the current class' parent class.
A well-known programming theory is inheritance, and PHP's object model takes advantage of this principle. This rule will have an impact on how various classes and objects interact with one another.
For instance, when extending a class, the subclass inherits all of the parent class's protected and public methods, properties, and constants. They will continue to function as they did before a class overrides them.
As a result, extra functionality can be implemented in related objects without having to reimplement all of the shared code, which is helpful for defining and abstracting functionality.
A child class cannot access the private methods of a parent class. Because of this, child classes are free to reimplement a private method without following the conventions of inheritance. Private methods, however, were subject to final and static limitations prior to PHP 8.0.0. Since private final constructors are a typical approach to "disable" the constructor when using static factory methods instead, PHP 8.0.0 only enforces this restriction on private methods.

An array is a type of data structure used in computer science that holds a set of elements that are all uniquely recognised by at least one array index or key. An array is stored in a way that allows a mathematical formula to determine each element's position given its index tuple.
The problem with the removeDups method is that it only checks for duplicates that are adjacent to each other and removes one of them. It does not remove all duplicates.
So in the example, the values 5 5 5 5 6 6 3 3 are all duplicates, but only one of each pair is removed by the method. That's why the resulting myData is 2 7 5 5 5 6 6 3 3.

A cost-effective method of offering web hosting services and making efficient use of the resources already present in IT infrastructure is server virtualization. Servers only utilise a small portion of their computing power without server virtualization. Because only some of the network's servers are assigned the burden, servers end up being idle. Overcrowding and underutilized servers in data centers result in resource and electricity waste.

Have you ever used the electronic fund transfer process? Were you satisfied with the result?
An EFT transfer is typically extremely simple. The sender of the funds and the recipient of the payments are the two persons involved.
What happens when sender requests a transfer?When a sender requests a transfer, the request travels from the sender's bank to the receiver's bank via a number of digital networks that can either be connected to the internet or come from a payment terminal.
Senders can range from an individual paying a vendor for a service like energy to an employer, a business, or both. Similarly, beneficiaries can be organizations like workers, suppliers of commodities, retailers, and utility companies. The majority of payments are cleared or finished, within a few days.

The Five Layer Model Physical layer. The physical device that interconnects the computers, their specification and how the signal is sent over this connection all comes in the physical layer. • Data link layer. It is basically all about defining a common way to interpret these signals so that a device can communicate with each other. The most common protocol used here is Ethernet. • Network layer. It allows different networks to communicate with each other using devices called routers • Transport layer. The transport layer finds which client and server programs are supposed to get that data. The most common protocol used here is TCP/IP . • MAC address. It is the address embedded in your hardware device (which will constitute a node of the network) permanently during its manufacturing. • IP address. Unlike the Mac address, it is not permanent and not embedded on any hardware it is the address of the network it might change when you are at home connected with the wifi and different when you are connected with the railway station's wifi even the devices in both cases are the same. • TCP port. A port is a 16-bit number that's used to direct traffic to specific services running on a networked computer. For example, port 80 is a port in which a web server listens for the web request. • Checksum check. It is a method used to check the correctness of data during the transmission from one place to another. • Routing table. It is a table in which the router device used to locate the destination IP address. • TTL or time to leave is the value assigned in the TTL field which tells the data when to leave the network. Let's begin our journey. Suppose there are two networks Network A and Network B with network space 9.5.4.0/24 and 125.5.45.0/24 respectively. These two networks are connected to the same router with two network interfaces having IP 9.5.4.1(on network A) and 125.5.45.1(on network B). Now suppose a laptop or desktop which is a client in this case which is a part of the Network A having IP 9.5.4.23. Again assume that a server which is connected to Network B has IP address 125.5.45.34 and has a web server which is listening on port 80. Now our clients want to access a website whose IP address is 125.5.45.34. He opens any browser and enters this IP address in the search bar and hits enter. The browser then communicates with the local networking stack, which is the part OS responsible for managing networking functions. Browser tells that it wants to establish a TCP connection with the server 125.5.45.34 through port 80. Then the networking stack will check its own subnet and find that 125.5.45.34 is on another network so the client has to send data through its gateway which has the network interface of 9.5.4.1. Then the client checks its ARP table to find out what is the MAC address of its gateway. There are two possibilities: It finds the MAC address. It doesn't find the MAC address. If it didn't find it first it will get it through an ARP request and then continue as described below : Our client then makes an ARP request for IP 9.5.4.1 which is sent to all devices connected to the same network having the same hardware broadcast ID of all Fs. When the router on this network receives this request it knows that it is for me and sends an ARP response with its own MAC address
The TCP/IP idea is built upon a five-layer networking architecture. These are the physical, data link, network, transport, and application layers, arranged from bottom (the link) to top (the user application).
What is meant by TCP?The Transmission Control Protocol (TCP) standard outlines how to start and sustain a network conversation via which applications can exchange data. TCP collaborates with the Internet Protocol (IP), which establishes the rules for how computers exchange data packets.Many internet applications, including as the World Wide Web (WWW), email, File Transfer Protocol, Secure Shell, peer-to-peer file sharing, and streaming video, heavily rely on TCP.Known as TCP, Transmission Control Protocol. It is a connection-oriented, dependable protocol that exists at the transport layer. IP stands for internet protocol. It is a network layer protocol that does not require connections and is in charge of transmitting packets to network nodes.To learn more about TCP refer to:
