1. When using routers, you need many routers in order to route the information to the correct location, as one router will not be able to manage this task. Explain how the routing schemes handle this problem.
Ans.
Routing scheme means to find a path from once place to another on which packets can travel. In most of the cases, we need multiple routers in order to route the packet to the destination. Routing contains three elements:
Routing protocols, Routing Algorithms, and Routing databases.
• Routing protocols allow the information to be gathered and distributed.
• Routing algorithms are used to determine paths.
• Routing databases, which will store all the information that the routing algorithm has discovered.
These elements in turn help the information to be routed to the correct

5. In your own words explain the concepts of RPC and RMI.
Ans.
RPC: Remote Procedural Call allows a client to invoke services by making a local procedure call, instead of accessing remote services by message passing (sending and receiving messages).
Suppose a process on machine X calls a procedure on another machine Y. The calling process (machine X) gets suspended, and procedure parameters are transferred to machine Y and procedure is executed on machine Y. Then after when the procedure finishes, results are transferred back to the calling environment (machine X), where execution resumes as if returning from regular procedure call.
RMI: Remote Method Invocation allows an object that lives in one process to invoke methods of an object that lives in another process.
It includes three software components:
• Proxy: which behaves like remote object to clients. It marshals arguments, forwards message to remote object, unmarshals results and returns result back to client.
• Skeleton: which is a server side stub. It is responsible for unmarshalling arguments, invokes methods, marshals results and sends the results to sending proxy
rapidly chooses how to convey the set of uses and framework servers over different machines in the cloud. Large portions of the conventional parallel applications for the most part utilize an altered number of strings on the other hand procedures characterized as a parameter toward the begin of the application. The choice for the number of strings is frequently chosen by the client in a push to completely use the parallel assets of the framework or to take care of top demand of a specific administration. fos utilizes the duplicated server model which permits extra transforming units to be alterably included amid runtime permitting the framework to attain a finer use for element workloads and lightening the client from such
The first opportunity of the organization having identified the need for a n house, fulltime float provider or Locum Tenums on call. Based upon the number of patients that were being cancelled per month on average, close to 700. The information was extracted from our data warehouse. Once the information was compared to other health care systems who were experiencing similar problems, the need was identified for a float provider/Locum Tenums (on call) to be housed at the parent facility. The float provider/ Locum Tenums will be used in several aspects that will help to continue to improve access to care. They will be available when a provider calls in so clinic will not have to be cancelled. The float provider/Locum Tenums will be able to see overflow walk in patients if he or she is not providing clinic coverage and or write prescription scheduled medication for providers who are on scheduled
In this report I will discuss different solutions for PVMS to help them improve network communications between the stores and head office, and centralize procedures for recording stock. This report will list the advantage and the disadvantage of each one.

ANSWER: User Configuration can be used in Group Policy to set policies that apply to users, regardless of which computer they log on to. User configuration contains various sub items for:
The two systems may not be identical. In order for the procedure to function and relay information properly there needs to be a conversion of the information into a form that can be handled by each system at either end when data is submitted.
Enter the Remote Authentication Dial In User Service (RADIUS), a commonly used authentication system. Most remote-access equipment vendors have supported RADIUS in their remote-access ser-vers. Many virtual private networking equipment companies also are supporting the use of a RADIUS server for user authentication.
These ‘frames” influence how I think. For example, every time when I saw some children are playing on the ground with their hands touch the ground, I thought this was wrong and their parents should have stop them playing on the ground. Because my parents yelled at me if my hands were touching the ground in the public when I was a child. They explained to me it was very dirty with a lot of germs. My parents have built a frame of how I feel about the public ground, which is dirty and a lot of germs. After I watch the video of Dr. Ness, thinking outside the box and changing the point of view are some of the tools to break these “frames”. (&Ness, 2011) Now, I think that touching the dirty ground may help strengthen the immune system.
Ghost Multicasting allows one computer, the Ghost Server, to download a Ghost image from the Server and then redirects the image to other workstations, the Ghost Clients, through the use of TCP/IP settings over the network.

Explain how the two important transport protocols deliver messages on behalf of the application and discuss the differences between them
Interfaces are used to consider the existing communication services and the components are used to implement the interfaces. These components and interfaces use a message buffer called message_ t that is implemented as nesC structure. This message buffer message_ t was used as TOS_ Msg in the first version of Tiny os and in the latest version of it has been replaced as message_ t. In the first version of the tiny os the message buffers were accessed directly but in the latest version they cannot be accessed directly instead this function can be read and written in the form of mutator and accessor functions.
