Along with an IP address, a subnet mask, and a name server, the other thing required for a computer to operate on a network is a primary gateway. The primary gateway acts as an access point which forwards information to another network or the internet.

The length of the inclined plane divided by the vertical rise, or you can call it run to rise ratio. The mechanical advantage would increase as the slope of the incline decreases, but problem is that the load will have to go a longer distance. The mechanical advantage would be slope of the incline. I also got confused on a question like this and did some research. Hope this helps!

Westkost [7]

Answer:

Bits

Explanation:

The protocol data unit is the representative unit of data in the OSI layer of a network. The OSI system has seven layers.

The physical layer is the first layer of the system and the protocol data unit is represented as bits of data.

Note that the term packet is the PDU for data in the network layer of the OSI network system.

What are the benefits of writing functions that use parameters and return List 2 please and explain what is return
Ratling [72]

<u>Answer and explanation:</u>

There are many benefits of writing functions that use parameters and return. Some of them are:

1. Flexibility: With functions having parameters, several values of the parameters can be used at invocation time thereby making the application flexible. For example, given the following function in Java.

<em>public void showName(String name){</em>

<em>    System.out.println("Your name is " + name);</em>

<em>}</em>

To call this method (function), the programmer could use various values for the name parameter used in the function like so:

showName("John");

showName("Doe");

If the function didn't have a parameter, it is possible it will only print a hardcoded name every time the function is called.

2. Scope Control: When a function is allowed to return a value, it helps to work around scope issues since variables declared within a function are limited to that function and do not exist outside the function. This means that the values of these variables cannot be used anywhere else outside the function in which they are being declared. However, if the function returns a value, the value can be used anywhere else in the program.

For example:

<em>public String getDouble(int x){</em>

<em>    int y = x * 2</em>

<em>    return y;</em>

<em>}</em>

The function above returns twice the value of the argument supplied to it. Since the integer variable y is declared within the function, it's value cannot be used outside the function. However, since the value is being returned by the function, it could be used anywhere the function is being called. Thanks to the return keyword.

In a block of addresses we know the IP address of one host is Roll no. Roll no. Roll no. Roll no./20.What is the first address a
lesya [120]

Answer:

If there’s one topic that trips people up (both new and experienced) in the networking industry, it is that of Subnetting.

One of the reasons this happens is that one has to perform (mental) calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting.

In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples.

Note: While subnetting applies to both IPv4 and IPv6, this article will only focus on IPv4. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.

IP address network

For example, any traffic with a destination IP address of 192.168.1.101 will be delivered to PC1, while traffic addressed to 192.168.1.250 will be delivered to SERVER.

Note: This is an oversimplification of things just for understanding sake and refers to Unicast (one-to-one) IPv4 addresses. Traffic sent to Multicast (one-to-many) and Broadcast (one-to-all) IP addresses can be delivered to multiple devices. Also, features like Network Address Translation (NAT) allow one IP address to be shared by multiple devices.

To help your understanding of IP addresses and subnetting, you need to resolve the following fact in your head: Computers think in binary, that is, 0s and 1s. Therefore, even though we see an IP address represented like 192.168.1.250, it is actually just a string of bits – 32 bits in total for IPv4 addresses.

To make them more readable for humans, IPv4 addresses are represented in dotted decimal notation where the 32 bits are divided into 4 blocks of 8 bits (also known as an octet), and each block is converted to a decimal number.

For example, 01110100 in binary is 116 in decimal:

A unicast IPv4 address such as 192.168.1.250 can be divided into two parts: Network portion and Host ID. So what does this mean? Well, IPv4 addresses were originally designed based on classes: Class A to Class E. Multicast addresses are assigned from the Class D range while Class E is reserved for experimental use, leaving us with Class A to C:

Class A: Uses the first 8 bits for the Network portion leaving 24 bits for host IDs. The leftmost bit is set to “0”.

Class B: Uses the first 16 bits for the Network portion leaving 16 bits for host IDs. The two leftmost bits are set to “10”.

Class C: Uses the first 24 bits for the Network portion leaving 8 bits for host IDs. The three leftmost bits are set to “110”.

Note: The range of Class A is actually 1-126 because 0.x.x.x and 127.x.x.x are reserved.

With these classes, a computer/device can look at the first three bits of any IP address and determine what class it belongs to. For example, the 192.168.1.250 IP address clearly falls into the Class C range.

Looking at the Host ID portion of the classes, we can determine how many hosts (or number of individual IP addresses) a network in each class will support. For example, a Class C network will ideally support up to 256 host IDs i.e. from 00000000 (decimal 0) to 11111111 (decimal 255). However, two of these addresses cannot be assigned to hosts because the first (all 0s) represents the network address while the last (all 1s) represents the broadcast address. This leaves us with 254 host IDs. A simple formula to calculate the number of hosts supported

Explanation: Final answer is Start address: 192.168.58.0 + 1 = 192.168.58.1

End address: 192.168.58.16 – 2 = 192.168.58.14

Broadcast address: 192.168.58.16 – 1 = 192.168.58.15
