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:

  1. If the main cable fails or gets damaged the whole network will fail.
  2. As more workstations are connected the performance of the network will become slower because of data collisions.
  3. 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.

Research and discuss the similarities and differences between cloud computing and client-server computing. Discuss the pros and
harkovskaia [24]

Answer:

Cloud computing as a virtual hosting tool, is much more theoretical. Both servers, applications, and communications are hosted in the cloud, off property, rather than being available via computer machine whereas In computing client/server, a controller gets client requests mainframes and needs to share its services, programs and/or data of one sometimes more client systems on the internet, and a client would be a portable platform that specific portions with a server and make use of a finite resource.

Explanation:

<u>Similar to cloud computing and client-server computing: - </u>

  • The cloud computing and client-server networking underpinning principles are the same. That is contact between client and server.
  • Throughout networking and client-server networking, user nodes can communicate (queries) with databases that live locally or are located in many other networks.

<u>Difference between computing and client-server computing: </u><u>- </u>

Resources: -

  • In computing client-server, the corporation or association controls the tools.
  • The services are offered in cloud computing by third parties or other businesses.

<u>The purpose of cloud computing and client-server computing is different:- </u>

  • Client-server computing is targeted at use. In computation, client-server clients request a product from the cloud. The operating system runs the test, then returns it.
  • Cloud computing is a sort of system in which the IT-related services are leased to the clients as a contract.

<u>Pros and cons of Cloud Computing:- </u>

The Pros:-

  • Lower costs for business:-The cloud is saving a lot of money for a medium-sized or small enterprise.
  • Better Reliability:- A dedicated group of experts performs all programming with such a cloud computing alternative.

The Cons:-

  • Limited Control:- When a firm stores cloud data, they have very limited control of it.
  • There have been security issues. The cloud isn't too attuned for every company to position some information on even a cloud.

<u>Pros and cons of client-server computing:- </u>

The Pros:-

  • Improved data sharing:- Data stored via the normal business method and processed on a server is available over an approved connection for the intended users.
  • Security:- Database has stronger access control and methods to ensure data could only be accessed or abused by approved clients.

The Cons:-

  • Overloaded Servers:- When multiple simultaneous requests from the client are made, the server is significantly overloaded, causing congestion in traffic.
  • Impact of centralized architecture:- Because it is centralized if a vital server fails to satisfy customer requests, the client-server then lacks good network robustness.
