2. Network types
1. Peer-to-Peer network
Peer-to-peer networking (P2P) is a distributed application architecture that partition tasks or workloads between peers. The peers all have the same perks, equal participants in the app. They are thought to form a network of peer nodes. Peers make part of their resources, such as processing power, disk storage or network bandwidth, available directly to other network participants without the need for central coordination of the machine. server or server is stable. Peer is both a provider and a resource consumer, as opposed to the traditional client-server model in which resource consumption and provision are split. Table 1 P2P network Benefits of peer to peer network Constraints of peer to peer network
- No network operating system required.
- There is no need for an expensive server as individual workstations are used to access files.
- There is no need for expert staff like a network technician because each user sets their own permissions for the files they are willing to share. - Because each computer can be accessed by someone else, it can slow down the user's performance. - Files and folders cannot be centrally backed up. - Files and resources are not organized centrally in a particular shared area. They are stored on individual computers and can be difficult to identify if the Figure 2 P2P network Figure 3 P2P network
- Much easier to set up than a client-server network - no specialized knowledge required.
- If one computer fails, it will not interrupt any other part of the network. It just means that those files were not available to other users at that time. computer owner does not have the proper storage system.
- Ensuring that viruses are not introduced to the network is the responsibility of each individual user.
- There is little or no security besides the permissions. Users often don't need to log onto their workstations.
1. Client/Server network
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. Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system. A server host runs one or more server programs, which share their resources with clients. A client does not share any of its resources, but it requests content or service from a server. Clients, therefore, initiate communication sessions with servers, which await incoming requests. Examples of computer applications that use the client-server model are email, network printing, and the World Wide Web.

WAN (Wide area network) WAN is a combination of LAN and MAN network connected together through satellite, fiber optic cable or wire cable. This wide area network can both be connected to a private network and can create large connections, covering an entire country or the globe. The protocol used mainly in the WAN is TCP / IP protocol. The connection path of the WAN network is available by changing according to each installation location. Characteristics: WAN bandwidth is the lowest, so the connection is very weak. The connection capacity is very wide and unrestricted. On top of high installation costs and complex network management.
2. Network protocol and standards
1. Protocol
A network protocol is a set of rules that a network must follow. Network protocols are standards and formal policies made up of rules, procedures, and formats for communication between two or more devices over a network. Network protocol implements operations, policies and resolves end-to-end problems, so that data or network communication is fast, secure, and managed. Network protocols define rules and conventions for communication. Figure 7 WAN
TCP/IP protocol : is a set of communication protocols that implement the protocol stack on which the Internet and most commercial computer networks run. This set of protocols is named after its two main protocols, TCP and IP. Like many other protocol suites, the TCP / IP protocol suite can be thought of as a set of layers, each solving a set of problems related to data transmission, and providing layer protocols. a service's upper level is clearly defined based on the use of the lower layer services. Logically, the upper layers are closer to the user and work with more abstract data, and they rely on subordinate protocols to transform the data into forms that can eventually be physically transmitted. HTTP protocol : is one of the five standard Internet protocols, used to communicate information between a Web server and a Web client in the Client/Server model for the World Wide Web. DNS protocol : is a system that enables the conversion of easy-to-remember human domain names to their respective physical IP addresses. DNS helps in associating with network equipment for the purposes of locating and addressing Internet devices. The domain name resolution system distributes the responsibility of assigning domain names and mapping names to IP addresses by specifying the authoritative servers for each domain name. Servers with authoritative names are assigned to be responsible for their own domain name, and in turn can assign their own exclusive hostnames to subdomains. ICMP protocol : is a protocol of the Internet Protocol packet. This protocol is used by network devices such as routers to send error messages indicating whether a service exists, or whether a host or router address exists. ICMP can also be used to forward query messages. ICMP differs from transport protocols such as TCP and UDP in that it is not commonly used for exchanging data between systems, nor is it frequently used by end-user network applications.
2. Standards
Networking standards define the rules for data communications that are needed for interoperability of networking technologies and processes. Standards help in creating and maintaining open markets and allow different vendors to compete on the basis of the quality of their products while being compatible with existing market products. Some standard organizations:

requirements
1. Network topology
A network topology is an arrangement of the various network elements of a communication network, often represented graphically. Network topology is an application of graph theory in which different network devices are modeled as nodes and the connections between the devices are modeled as links or lines between nodes. Physical network topology is the location of the different components of the network, and different connectors often represent physical network cables and nodes typically represent physical network devices. Figure 8 Physical topology diagrams (Bus, Star, Ring, Mesh, Tree, Point to point) Figure^9 Hybrid topology diagram
Logical network topology illustrates, at a higher level, how data travels across the network. Figure 10 Logical topology diagram
2. Bandwidth
Bandwidth is the term used to refer to the amount of data transferred per second. This concept also represents the data transmission rate of a transmission line. Accordingly, the larger the bandwidth, the faster the data transfer speed. In computer networks, Bandwidth is typically measured in bits per second (bps). Today's computer networks typically have bandwidth speeds of up to millions of bits per second (Mbps) or even billions of bits per second (Gbps). Bandwidth Limit is a function limitation of the use of action to download / upload the user when access on the network general internet to ensure the quality of the way of transmission line. This function ensures the devices access the same network speed. Figure^12 Bandwidth example
In addition to dedicated bandwidth links with maximum available bandwidth, it is often sold for a fixed monthly price, bandwidth on demand, or known as dynamic bandwidth allocation or burst bandwidth, is a options that allow subscribers to increase the amount of bandwidth available at specific times or for specific purposes. Bandwidth on demand is a technique that can provide more capacity on a communication link in response to temporary data traffic bursts that require more bandwidth. Instead of over-providing networks with expensive links, carrier-provided dynamic bandwidth allocation is often used in wide area networks to increase capacity as needed for a particular event or at a specific time of day. Using this technique, bandwidth on a shared telecommunications network can be increased and users only pay for the additional bandwidth they use. Stable bandwidth is available through many service providers, because the network links they give their customers more bandwidth, but the customers only pay for the energy they need.
III. The operating principles of networking devices and server
types.
1. Networking devices
Network device is known by many different names such as network device, network hardware, network device, etc. However, all names have the same meaning but have different purposes. After covering the various topics about network topologies and their pros and cons, we are here again with a series on network devices. Different devices operate in different layers of a computer network. Figure 13 Bandwidth
2. Network server
A network server is a powerful computer that provides various shared resources to workstations and other servers on a network. The shared resources can include disk space, hardware access and email services. Any computer can be a network server, but what separates a server from a workstation is not the hardware, but rather the function performed by the computer. Some network servers:
- Files servers
- Print servers
- Client servers
- FPT servers
- Web servers • Proxy servers • Mail servers Figure 15 Network server
IV. the inter-dependence of workstation hardware with relevant
networking software
1. Interdependence
Interdependence is the state of the relationship between two parties in which the damage from the severance of the relationship or the reduction of exchanges is equal to each party. Interdependence refers to the state in which actors or events in different parts of the system affect each other. Example: A discount appears to benefit one business if it is completely separate from other businesses. But if this behavior results in other businesses also having to lower their selling prices, all businesses lose profits. Because of this interdependence, companies often seek to avoid price competition and use price guidelines to coordinate their prices.
2. Workstation hardware
A workstation is a special computer designed for engineering or science applications. Primarily used by one person at a time, they are typically connected to a local network and run multi-user operating systems. Workstations offer higher performance than mainstream PCs, especially in terms of CPU and graphics, memory capacity, and multitasking capabilities.
