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).

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.

TCP/IP is a two-layer protocol, with the transport layer (TCP) in charge of providing dependable end-to-end communication and the Internet layer (IP) in charge of directing packets from one host to another.
What is an Internet layer?Network packets are transported over network boundaries, if necessary, to the target host indicated by an IP address, using a set of internetworking techniques, protocols, and standards collectively referred to as the "internet layer" of the Internet protocol suite.A five-layer networking architecture serves as the foundation for the TCP/IP concept. The physical, data link, network, transport, and application layers are listed from bottom (the link) to top (the user application). For data packets to transit across networks and arrive at their destination, the Internet Protocol (IP) is a protocol, or set of rules, that specifies how to address and route them.The downlink of 5G allows for the transmission of up to 8 layers to a single user.To learn more about Internet layer refer to:

This program, named hoursandminutes, is designed to take a value representing minutes worked on a job, and convert it to display the value in hours and minutes.
Write a program named hoursandminutes?#include <iostream>
using namespace std;
int main()
{
int minutes;
minutes = 98;
int hours, remainingMinutes;
hours = minutes/60;
remainingMinutes = minutes % 60;
cout << minutes << " minutes is " << hours << " hours and " << remainingMinutes << " minutes." << endl;
return 0;
}
Using JavaScript, the program will declare a variable called “minutes” and give it an assigned value. The program will then use a calculation to convert the minutes value to hours and minutes, and print the result. The calculation to convert minutes to hours uses the modulo operator (%) to calculate the remainder of minutes divided by 60. This remainder is then added to the hours, which is the result of dividing minutes by 60. For example, if 98 is assigned to the minutes variable, the output would be: 98 minutes is 1 hours and 38 minutes. The program would use the following calculation to determine this result: Hours = Math.floor(minutes / 60);Minutes = minutes % 60;The program would then print the result to the console:console.log(minutes + “ minutes is ” + hours + “ hours and ” + minutes + “ minutes.”);This program is a useful tool to quickly convert minutes to hours and minutes.To learn more about a program named hoursandminutes refer to:
