Presentation 2

[Virtual Presenter] Good morning everyone and welcome to our presentation on computer network architecture. This is an important topic for anyone interested in understanding how networks function and how different types of architectures can impact overall performance. My name is your teacher for this class and I am joined by my fellow classmates Pratik Sapkota Pratik Chapagai Riwaj Lohani Satish Sapkota and Ayush Para Juli. We will be discussing the general theme of network architectures specifically focusing on client-server peer-to-peer and centralized architectures as well as the advantages and disadvantages of each. So let's dive in and explore the world of computer networks together..

[Audio] "Welcome back students. Continuing our discussion on computer network architecture let's move on to slide number two. Network architecture is the design that explains how computers on a network interact and communicate with each other. It can be classified into three types: client-server peer-to-peer and centralized. Today we will be focusing on client-server network architecture. This type delegates tasks between servers and clients creating a strong foundation for efficient and scalable networked applications. Moving on to slide number three we will take a closer look at the features of client-server network architecture..

[Audio] Moving on to the third slide we will be discussing computer network architecture specifically the client-server model. This model divides tasks between servers and clients serving as a foundation for efficient and scalable networked applications. The next slide shows the benefits of centralized data management cost-efficiency and high performance with low latency. Let's further explore the advantages and features of this architecture..

[Audio] Today's discussion will be on the advantages of client-server architecture. This type of network architecture is centralized allowing for easier management and maintenance as all data and services are stored in one location. It is also cost-efficient requiring less resources on the client side and saving money for businesses and organizations. Moreover it offers high performance and low latency due to the server's ability to handle multiple requests simultaneously. These are just a few benefits of client-server architecture. Thank you for listening and I hope this has helped you understand the topic better..

[Audio] As previously discussed computer network architecture plays a significant role in the transmission and access of information in our modern world. However like any technology it also has its drawbacks. In this presentation we will examine the downsides of implementing a client-server architecture. Firstly it should be noted that transitioning to a client-server architecture is a complex process that can take anywhere from two to five years. During this time the system may not run as efficiently as desired. Another issue with a client-server architecture is maintaining control. The system is centralized meaning all data is stored and managed in one location. This makes it susceptible to unauthorized use privacy breaches and viruses. As a result it can be challenging to prevent these problems and uphold a secure environment. To summarize although client-server architecture has many advantages it's essential to be aware of these potential challenges. As tech-savvy individuals it is crucial to stay informed and address these issues to ensure the smooth operation of our networks..

[Audio] Take a look at slide number 6 where we will discuss peer-to-peer network architecture. This type of network involves multiple computers connected to each other allowing for resource sharing and increased reliability without a central system administrator. Next we'll explore the advantages of peer-to-peer networks on the following slide..

[Audio] Moving on to slide number 7 we will now discuss the advantages of peer-to-peer network architecture. This type of architecture offers multiple benefits as stated by the quote. Firstly all resources and contents are shared equally among all clients allowing for easier access and collaboration between peers. Secondly the network is more reliable without any central dependency. Even if one peer fails it will not affect the functioning of other peers. Finally the need for a full-time System Administrator is eliminated as each user can control their own shared resources. Moving on to the next slide it is important to note that peer-to-peer networks also have some drawbacks which we will address..

• DISADVANTAGES OF A PEER TO PEER NETWORK • SOME DISADVANTAGES OF PEER TO PEER NETWORK ARE AS FOLLOWS: ▪ In this network, the whole system is decentralized thus it is difficult to administer. ▪ Security in this system is very less. ▪ Data recovery or backup is very difficult since each computer should have it's own back-up system. 1 8.

[Audio] "Good afternoon everyone. We will now continue our discussion on computer network architecture with slide number 9 titled 'Centralized Network'. A centralized network is a type of network where all users are connected to a central server. This server is responsible for storing user accounts and other information. For example instant messaging uses a centralized network for communication. Moving on to our next slide we will explore the benefits and drawbacks of a centralized network such as increased data security and cost reduction but also the need for large data storage and potential performance issues with high traffic. Keep this in mind as we learn more about computer networks. See you soon..

[Audio] As we continue our lesson on computer network architecture we will be discussing centralized networks. This type of network has both advantages and disadvantages that we need to understand. Let's start with the advantages. Firstly centralized networks provide high data security which is important in today's digital world where data breaches are common. Secondly it helps reduce cost by centralizing resources and eliminating the need for multiple systems. However there are also disadvantages to consider. Centralized networks require large data storage which can be expensive and time-consuming to manage. In addition high traffic can lead to slower connections and frustrated users. As we continue remember to consider both the pros and cons of centralized networks to make informed decisions in your future network architecture projects..

1 11 Network Topologies Ring topology.

[Audio] We will be discussing network topologies in computer architecture. This refers to how computers are arranged and connected in a network. There are various types of network topologies but we will only be focusing on those used in L-A-N--. These include bus or linear topology star topology and ring topology. Let's take a closer look at each of these topologies and their characteristics..

[Audio] In the next aspect of computer network architecture we will be discussing slide number thirteen. Our topic is the bus or linear topology which is known as the simplest form of network topology. This type of topology connects all nodes such as computers and servers to a single cable through interface connectors. Moving on to the next slide we will be examining the collected samples which contain a variety of information..

[Audio] In today's class we will discuss the advantages of using bus topology in computer network architecture. It is a popular choice for small networks due to its simplicity and ease of setup and extension. It is also a cost-effective option compared to other network topologies. One major benefit of bus topology is its use of shorter cable length resulting in cost savings and improved efficiency. When designing a computer network it is worth considering the benefits of bus topology as it may suit your needs best. That's all for now thank you for listening..

DISADVANTAGE OF BUS TOPOLOGY • If the main cable (i.e. bus) encounters any problem, whole network breaks down. • There is maximum chance of collision of data. • It is difficult to detect and troubleshoot fault at individual station. 6/12/2024 15.

6/12/2024 16 Star Topology This is the most commonly used and popular topologies in LAN . It also manages and controls the entire network system .There is no chance of data collision..

[Audio] "Moving on to our next topic we will be discussing the advantages of using a star topology in computer network architecture. This type of network offers improved performance easy addition of new nodes centralized management for efficient monitoring and minimal impact in case of node or link failure. Please remember these details as we move on to the next slide for further explanation..

*DISADVANTAGES OF STAR TOPOLOGY SOME DISADVANTAGES OF STAR TOPOLOGY ARE AS FOLLOWS: • If the central device(hub) fails ,the entire network will break down. • The use of hub, a router or a switch as the central device increases the overall cost of the network. • Performance as well number of nodes which can be added in such topology is depended on capacity of the central device. 6/12/2024 18.

[Audio] Welcome students of class 10. Today we will be discussing the concept of computer network architecture specifically focusing on ring topology. As seen on slide 19 in a ring topology all nodes are connected in a closed circular loop. This allows data to travel in only one direction either clockwise or anti-clockwise eliminating the possibility of data collisions and ensuring efficient data transmission. Ring topology is also a type of peer-to-peer network where all nodes have equal status and can function as both a client and a server. Keep these points in mind as we continue with our lesson..

[Audio] We will discuss the advantages of ring topology in computer network architecture. This type of network topology is organized reducing data collision for smooth data transmission. Eliminating the need for a network server to control connectivity between workstations simplifies the structure and lowers implementation and maintenance costs. Additional components like new workstations won't affect overall network performance making expansion easy without disrupting functionality. In ring topology all computers have equal access to network resources ensuring fairness and equal distribution. In conclusion the advantages of ring topology make it a popular choice for computer networks offering efficient data transmission a simple structure cost-effectiveness and equal resource access..

[Audio] In our presentation on computer network architecture we will discuss the disadvantages of ring and star topologies. Ring topology can cause network disruptions if one workstation or port goes down leading to communication and connectivity issues for all devices. Star topology is dependent on the wire connecting components and if it malfunctions the entire network can go down. Additionally data transmission can be slower compared to a star topology where packets must pass through all computers between source and destination. It is important to consider these drawbacks when choosing a topology for your network. Thank you for your attention and hope you have gained a better understanding of computer network architecture. Have a great day!.
