A network architecture refers to the high-level structure of a network and determines how the different components of a network will interact with each other. It also defines the protocols that will be used to communicate between the different components of the network.
A network architecture is a conceptual model that defines the structure, behavior, and more of a network and its components. It is a framework for understanding, designing, and managing networks.
What is meant by architecture of network?
A network’s architecture refers to its structural and logical layout. This includes how the network devices are connected and the rules that govern data transfer between them. There are many ways to approach network architecture design, which depend on the purpose and size of the network.
Network architecture is the way in which computers are organized in a system and how tasks are allocated between these computers. Two of the most widely used types of network architecture are peer-to-peer and client/server. Client/server architecture is also called ‘tiered’ because it uses multiple levels.
What is the main role of network architectures
A network architect is responsible for designing and building data communication networks. The networks they work on can range from smaller local area networks (LANs) to larger wide area networks (WANs), along with intranets. They work with various networking technologies and protocols to ensure that the network meets the needs of the users. Network architects also work with security features to protect the network from unauthorized access.
A network architecture rendering may help when conducting a threat assessment by identifying the transmission equipment, software, communication protocols, and infrastructure (wired or wireless) that enable devices to communicate and transfer data. This information can help to identify potential vulnerabilities in the network that could be exploited by attackers.
What are the 3 types of network architecture?
There are three common computer network architectures: peer-to-peer, client-server, and distributed.
Peer-to-peer networks are networks in which each node has equal responsibility and authority. There is no central server in this type of network. Instead, each node acts as both a client and a server.
Client-server networks are networks in which there is a central server that is responsible for providing resources and services to clients. Clients are typically devices that request and consume resources and services from the server.
Distributed networks are networks in which each node has its own responsibility and authority, but there is also a degree of cooperation between nodes. In this type of network, each node can act as both a client and a server.
There are two types of network architectures that are commonly used: Peer-To-Peer network and Client/Server network.
Peer-To-Peer network:
In a peer-to-peer network, each computer is both a client and a server. There is no centralized server that all the computers connect to. Instead, each computer connects to all the other computers in the network. This type of architecture is often used in small networks where all the computers are located in close proximity to each other, such as in a home or small office.
Client/Server network:
In a client/server network, there is a centralized server that all the computers connect to. The server provides services to the clients, such as file sharing, email, and so on. This type of architecture is often used in larger networks where the computers are not located close to each other.
What are four basic network architectures?
Network architectures are the basic building blocks of any network. They define how the network will function and what its capabilities will be. The four basic network architectures are:
-Fault Tolerance: A fault-tolerant network is one that limits the number of devices that are impacted by faults, as the Internet will fail at times.
-Scalability: A scalable network is one that can grow to accommodate more users and more traffic without becoming overloaded.
-Quality of Service (QoS): A network with quality of service (QoS) guarantees is one that can provide certain levels of service to its users despite fluctuations in traffic or other conditions.
-Security: A secure network is one that is designed to protect its users’ data and prevent unauthorized access.
PAN, LAN, MAN, and WAN are all different types of computer networks. Each has its own advantages and disadvantages, and each is best suited for different purposes.
PANs are small and personal, making them great for individuals or small groups. They are easy to set up and usually don’t require much infrastructure. However, they have limited range and bandwidth, and aren’t well suited for large amounts of data.
LANs are larger and more complex than PANs. They are best suited for businesses and other organizations that need to share data and resources among a group of people. LANs usually have more bandwidth and range than PANs, but they can be more difficult to set up and manage.
MANs are even larger than LANs, and are designed to span an entire city. They are often used by ISPs to provide internet service to an entire metropolitan area. MANs usually have high bandwidth and large range, but can be very expensive to set up and maintain.
WANs are the largest and most complex type of computer network. They span vast distances, often covering an entire country or even the entire world. WANs are used by large organizations, such as governments and multinational corporations, to share data
How many network architectures are there
P2P – Each workstation has equal ability to share resources and act as both a server and a client. If one computer is down, the rest of the network is not affected.
Client/server aka tiered – One computer acts as a server, providing resources and information to the rest of the computers on the network which act as clients. If the server is down, the network is down.
Network diagrams are a great way to visualize how network components are connected. To create a network diagram:
1. Select a network diagram template
2. Name the network diagram
3. Remove existing elements that you don’t need on your diagram
4. Add network components to the diagram
5. Name the items in your network diagram
6. Draw connections between components
7. Add a title and share your network diagram
What are the five 5 elements of a network?
Computers:
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.
Transmission medium (wired or wireless):
A transmission medium is a material substance that can propagate energy waves. Transmission media include the air, water, and vacuum of outer space as well as glass, metal, and plastic pipes that transport fluids. All of these materials can be used to transmit electrical energy, mechanical energy, or electromagnetic energy.
Protocols:
A protocol is a set of rules that govern the format and transmission of data between two devices. Protocols are implemented in hardware, firmware, and software, and they enable devices to communicate with each other.
Network software:
Network software is a type of computer software that is designed to enable two or more computers to communicate with each other over a network. Network software typically includes a variety of software applications, such as email, file sharing, and VPN software.
Fault tolerance is the ability of a network to maintain some level of performance even in the event of failure of one or more of its components.
Scalability is the ability of a network to accommodate growth in traffic demand by adding additional capacity.
Quality of service (QoS) is the ability of a network to provide different levels of service to different applications.
Security is the ability of a network to protect its data and resources from unauthorized access.
Which network architecture are widely used
The client-server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. This model has a central server that performs all the tasks and services for the entire network. Usually, clients are workstations or personal computers that request information or services from servers.
Peer-to-peer is a decentralized communications model in which each node in the network acts as a client and server. This model is opposed to the client-server model where communication is usually handled by a central server. In a peer-to-peer network, nodes collaborate and share resources as equals. There is no centralized authority or hierarchy, and each node has the same powers and responsibilities.
A personal area network (PAN) is the smallest and simplest type of network. It is typically used to connect devices in close proximity to each other, such as a computer and printer in the same room.
A local area network (LAN) is a network that spans a small geographical area, such as a home or office. A LAN can be as small as two computers connected together with a cable, or as large as several thousand computers in a corporate campus.
A metropolitan area network (MAN) is a network that spans a large geographical area, such as a city. A MAN can be as small as two LANs connected together, or as large as several hundred LANs in a large metropolis.
A campus network is a network that spans a large geographical area, such as a university campus. A campus network can be as small as two LANs connected together, or as large as several thousand LANs in a large university.
A wide area network (WAN) is a network that spans a large geographical area, such as a country or continent. A WAN can be as small as two LANs connected together, or as large as several hundred LANs in a large country.

What are the 3 basic elements of a network?
A computer network is made up of hardware, software, and protocols. The hardware includes the devices that are used to connect the network, such as routers, switches, and cables. The software includes the operating system and other software that is used to manage the network. The protocols are the rules that govern how the network operates.
Two-tier architecture is easy to build and maintain because it only consists of two layers: the client tier and the database (data tier). Three-tier architecture is more complex, with an additional business layer in between the client and data layers. However, three-tier architecture is more scalable and efficient, making it the better choice for larger applications.
Warp Up
Network architecture is the layout of the computers, services, and other devices that make up a network. The architecture includes the hardware, software, protocols, and other components that make up the network.
There is no single answer to the question of “what is network architecture?” as the term can refer to a variety of different things. In general, network architecture refers to the overall structure of a computer network, including the physical layout of the network, the network topology, the network protocols that are used, and the software that controls the network.
