Problem: For multi access control, there are two approaches, those based on channel partitioning, and those based on random access. In packet switching, there are two rather similar approaches as well, namely, circuit switching and package switching. Discuss the similarities and differences in these two problem domains and the corresponding approaches g

Answers

Answer 1

The similarity between the two systems is the ability to connect many different communication devices and transfer data between a sender and a receiver. The main difference is the need for a connection for both to work.

We can arrive at this answer because:

Circuit and package quotation is very important for the connections of different communication devices.Furthermore, these two systems are used efficiently when a data transfer is required.However, even being used for the same purposes, they have many differences between them.The biggest difference is the need for a connection, as package switching is done without the need for a connection, while circuit switching needs a connection to act.

In addition, circuit switching is more widely used because of its ability to transfer data from one point to another via message transfer, while package switching is used when circuit switching is not available as it does the sending data more slowly across one drive.

Answer:

How to Set Up a Home Network- Beginners Guide

Today almost every home and small office has a local network, and an Internet connection.

The home network or small area network enables multiple devices e.g. PCs,tablets etc to connect to each other, and also to connect to the internet.

In this tutorial you will learn how you to build and setup a home or small area network and connect it to the Internet.

Explanation:

Choosing a Wired or Wireless Network

Do You Build a wired or Wireless Network? which is best?

Early (pre 2008) home networks were predominately wired networks.

Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router.

Wired Network Advantages

Fast typically 100 Mbps to 10 Gbps

Secure and reliable.

Wired Network Dis-Advantages

Doesn’t work with devices that don’t have an Ethernet port e.g. tablets and smart phones.

Not so easy and fast to setup as it requires running cables. However Homeplug or powerline adapters can be used instead.

Not so easy for visitors and mobile devices (laptops) to connect to.

Main Uses

It Is best used for network backbone i.e. connecting between router,network switches and wireless access points on different levels (floors).

What is CPU?

A central processing unit, often known as a central processor, main processor, or simply processor, is the electrical circuitry that processes computer program instructions. The CPU executes fundamental arithmetic, logic, controlling, and input/output operations as provided by the program's instructions.

The CPU is in charge of all data processing. It keeps data, interim outcomes, and instructions saved (program). It controls how all computer components work.

Therefore, it can be concluded that The CPU is in charge of acquiring program instructions, decoding each one, and performing the prescribed series of actions on the proper data.

System.out.println(prod1.Barcode);

System.out.println(prod2.Barcode);

}

}



public class Product {

public int Barcode;

}

Answers

Answer:

Explanation:

1st mistake: Barcode is written with upeer case, that's not the convention for variables in java, only classes.

2nd: Barcode is public, it is convention to always leave variables private then create getters and setters in case you need to change the value but never acess the variable outside the class it belongs. Also the class should at least have a default constructor in case you are going to instantiate an object outside it.

so the product class should be:

--------------------------------------------------------------------

public class Product {

private int barcode;

        public Product() {

        // default constructor

        }

public int getBarcode() {

 return barcode;

}

public void setBarcode(int barcode) {

 this.barcode = barcode;

}

}

-------------------------------------------------------------------------

3rd: in the main class now you can instantiate the 2 objects but you are gonna set the variable and get the value through the method, like this:

public class Main {

 

public static void main(String[] args) {

   

 Product prod1 = new Product();

 prod1.setBarcode(123456);

 Product prod2 = new Product();

 prod2.setBarcode(987654);

 System.out.println(prod1.getBarcode());

 System.out.println(prod2.getBarcode());

}

}

-----------------------------------------------------------------------------------

Assuming the 2 classes (main and product) are in the same package. But in case they are in different packages, just make sure to import the Product class into the Main class so that you can instantiante an object (new Product()) of it.

Write the function rindby() which stands for remove mark>if not divisiby by. The function removes all elements from the array that are not evenly divisible by the argument n. You can find out if a number is evenly divisible by n using the remainder operator: % (there will be nothing left over).
The function returns the number of items removed or -1 if the array was originally empty.
The function takes 3 arguments:
the array of int that may be modified.
the size of the array (use size_t as the type)
the int n used to check for divisibility
Here are two short examples:
int a[] = {2, 3, 4, 5, 6};
size_t size = 5;
int removed = rindby(a, size, 2);
// removed->2, a = [2, 4, 6], size = 3
size = 0;
removed = rindby(a, size, 3);
// removed-> -1, no change otherwise
In the first case, the numbers 3 and 5 are removed because they are not divisible by 2. Only the numbers that are divisible by 2 are left in the array.
In the second, size has been set to , so the input array is empty and the function returns - 1.
