We are given a pointer to the middle Node (or any other Node except the last Node) in the linked list, but we do not have access to the head pointer. We must delete that Node using that address.

Recall that the last node on the list is not the one that needs to be removed. We are unable to delete the node directly since doing so might disrupt the links in the Linked list because we lack access to the node's previous node through which to connect the link. Instead, before destroying the following node, we will replicate its data and links to the node pointed to by ptr.

The following is the algorithm:

We need to remove Node(i) from the list that looks like this:... -> Node(i-1) -> Node(i) -> Node(i+1) ->....

1. From Node(i+1) to Node(i), copy data (not a pointer, the actual data); the list will look like this:...-> Node(i-1) -> Node(i+1) -> Node(i+1) ->...

2. Put a temporary variable in which the NEXT of second Node(i+1) is copied.

The number next to OC refers to the data speed in the multiples of 51.84 Mbps, considering the base rate bandwidth of a very high connection speed service.

What is Bandwidth?

The maximum capacity of the wired and wireless communications link to transmit the data over the network connection in the given amount of time is indicated by network bandwidth. The number of bits, kilobits, megabits, or gigabits that can be transmitted in one second is commonly used to represent bandwidth.

Bandwidth, also known as capacity, describes the rate at which data is transferred. The notion that bandwidth is a measure of network speed is widely held.The more data a data connection can send and receive at the same time, the higher its bandwidth.

Bandwidth is analogous to the amount of water that can flow through a pipe in theory.The greater the diameter of the pipe, the more water that can flow through it at the same time. Bandwidth follows the same logic. The more higher the capacity of that communication link, the more is the data could flow through it per second.

In this network, there is no hierarchy; each participant is given the same privileges. Each computer has access to the other's data and can share resources like disk space, software, or peripherals.

Total bandwidth that will be reserved for these requests at routers are:

Router a

- The router "a" allocates a bandwidth 2mb/s to router "b"

Router b

- The router "b" does not allocates any bandwidth to router "c"

Router c

- The router "c" allocates a bandwidth 1mb/s to router "e"

Router e

- The router "e" allocates a bandwidth 3mb/s to router "h"

The bandwidth of 2mb/s from host 1 and a bandwidth of 1 mb/s from host 2 . So totally it allocates a bandwidth of 3mb/s

Set up a dynamic protection system that changes the set of accessible resources based on the time allotted to the three user categories. When the time comes, the domain of people who are qualified to play the computer game expands.

When the timer runs out, the user process will terminate or the revocation procedure will be initiated. The revocation may be instant, selective, or temporary. As time passes, so does the domain of users who are qualified to play computer games. They must execute for a specified user at the scheduled time.

Dynamic Protection Structure - DPS is an adaptive protection system that calculates the best protective functions and settings in real time when the distribution network's configuration changes. DPS can improve protection system sensitivity and selectivity over traditional protection schemes, enable more DG connections to the network, and automate portions of the protection system design process.

K-Means is a clustering technique that divides input data points into k groupings. The learning algorithm's training phase is represented by this grouping procedure. The outcome would be a model that, in response to the training that the model underwent, accepts a data sample as input and returns the cluster to which the new data point belongs.

In a very basic way, that's how content promotion and suggestion generally function. Websites may decide to group users into bubbles or clusters based on qualities or actions they have in common. By doing this, the suggested content will be relatively relevant because individuals who have previously engaged in similar behaviors are likely to be interested in related content.
