A disadvantage of a bus network is that <u>performance can decline as more users and devices are added</u>
<u></u>
Explanation:
- A bus network is an arrangement in a local area network (LAN) in which each node is connected to a main cable or link called the bus.
- The advantages of a bus network are: it is easy to install. it is cheap to install, as it doesn't require much cable.
The disadvantages of a bus network are:
- If the main cable fails or gets damaged the whole network will fail.
- As more workstations are connected the performance of the network will become slower because of data collisions.
- Every workstation on the network "sees" all of the data on the network – this is a security risk.
- Bus topology is used for small workgroup local area networks whose computers are connected using a thinnet cable. Trunk cables connecting hubs or switches of departmental LANs to form a larger LAN.
- Bus topology uses one main cable to which all nodes are directly connected. The main cable acts as a backbone for the network. One of the computers in the network typically acts as the computer server. The first advantage of bus topology is that it is easy to connect a computer or peripheral device.
Answer:
The solution code is written in Java.
- public class Rectangle {
-
- private double length;
- private double width;
-
- public Rectangle(double length, double width){
- this.length = length;
- this.width = width;
- }
-
- public double getArea(){
- return this.length * this.width;
- }
-
- public boolean rectangleSquare(){
- if(this.length == this.width){
- return true;
- }else{
- return false;
- }
- }
-
- public boolean equivalence(Rectangle rect){
- if(this.width == rect.width && this.length == rect.length){
- return true;
- }else{
- return false;
- }
- }
- }
Explanation:
Create a class, <em>Rectangle</em> (Line 1) and define two private attributes,<em> width </em>and <em>length</em> (Line 3 - 4). The reason to define the attributes as <em>double</em> type is because the width and length are presumed to be either an integer or a decimal value.
Create constructor which takes <em>width</em> and<em> length </em>as parameters (Line 6).
Next, the require methods, getArea(), isSquare() and overloaded equivalence() along with their expected parameters and return output, are created accordingly in Line 11 -28.
The unique impact him professionals have a coded data is combining knowledge of the clinical content, documentation principles, coding systems and data use provide accurate information for the industry. An example of HIM professional cohesion is the professional code of ethics. HIM field addressing a more global health care arena by collecting and aggregating data for the world health organization. The HIM curriculum is unique in that healthcare is a continual element throughout the academic program and HIM studies include biomedical sciences, information fields and management. Historically, the position of HIM director has been held by individuals with which AHIMA credentials is the RHIA
