1 Introduction

By the requirements of director of company We were visited A school and knew resource of this school had has, for solution problem we need to built cloud system with high speed LAN and strong security, easy to use, easy to manager display and cheap.Here is the project that I come up with:

1 Discuss the benefits and constraints of different network types and standards.

o Benefit of LAN:

+ A local area network (LAN) allows users to share resources such as printers, scanners, and storage devices This lowers the expense of purchasing and maintaining separate devices for each user + Users may quickly exchange files and data among themselves, enhancing cooperation and productivity

+ LAN enables administrators to administer and maintain the network from a centralized place, making it easier to monitor and solve difficulties

+ LAN may be guarded using firewalls, encryption, and other security measures, therefore protecting important data and information from unwanted access

o Constraint of LAN:

+ A local area network (LAN) allows users to share resources such as printers, scanners, and storage devices This lowers the expense of purchasing and maintaining separate devices for each user.

+ Users may quickly exchange files and data among themselves, enhancing cooperation and productivity

+ LAN enables administrators to administer and maintain the network from a centralized place, making it easier to monitor and solve difficulties

+ LAN may be guarded using firewalls, encryption, and other security measures, therefore protecting important data and information from unwanted access

● WAN: (Wide Area Network) refers to a sort of computer network that spans a broad geographic region, such as a city, nation,

or even the entire planet WANs are used to link devices that are physically separated from one another, such as computers indifferent offices or towns

Unlike a LAN, which is limited to a single building or campus, a WAN may connect numerous cities, nations, or even continents To send data across great distances, WANs typically use telecommunication technologies such as leased lines, satellites, and wireless connections

system failure.

o Constraint of WAN:

+ Latency is the amount of time it takes for data to transit from one point on the network to another Due to the enormous distances that data must travel between multiple sites, latency in WANs can be considerable This might create network delays and slow down performance

+ The quantity of data that may be transferred via a network in a given length of time is referred to as bandwidth WANs frequently have limited capacity, which can result in poor data transmission speeds and network congestion + WAN are frequently used to connect many offices or distant employees to a centralized network If the network is not adequately protected, this might lead to security vulnerabilities, possibly exposing sensitive data to unauthorized access

+ WAN are frequently created with several linked lines and devices, which can lead to failure spots If one connection

or device fails, the entire network may fail or become unreachable

+ Because to the requirement for specialized equipment and high-speed connections, building and maintaining a WAN can be costly Smaller enterprises and organizations may find it harder to install and maintain a WAN as a result

● MAN: Metropolitan Area Network (MAN) refers to a form of computer network that spans a wider geographic region than a Local Area Network (LAN) but is smaller than a Wide Area Network (WAN) (WAN) MANs may generally cover tens of kilometers, such as a city or a university

MANs are intended to connect numerous LANs and provide more bandwidth and quicker communication between devices within the same metropolitan area Businesses, institutions, and government entities frequently utilize them to link various sites within a city or campus

o Advantages:

▪ It is the simplest approach to discover and resolve faults

▪ It provides a highly effective and adaptive networking structure

▪ It is scalable, allowing you to expand your network

o Disadvantages:

▪ Hybrid topology design is difficult

▪ It is one of the most expensive processes.

2.3 Communication and Bandwidth:

• Define commutations in terms of networking: Communication is the process of switching packets between network tiers

in order to transmit data Network communication also enables programs to communicate with one another without concern for hardware

• Rules of communication:

o To communicate, a protocol is required

o To offer you with internet, you must have a network topology

o Choose an appropriate network type

o Choose an appropriate switch or router

• Bandwidth:

o Define: Bandwidth is a measurement of network packet and internet speed This is a critical network parameter for selecting the best network speed packages for your needs

o Bandwidth requirements for the networks: Users' bandwidth requirements vary depending on the work

▪ Just 64 Kbps bandwidth is required for audio

▪ Just 512 Kbps bandwidth is required for video

▪ Just 521 Kbps bandwidth is required for screen sharing

3 Discuss the operating principles of networking devices and server types.

3.1 Discuss 1 or 2 operating principles of a selected network device

- Modern: To connect to the internet, devices or hosts must have a modem A modem is a machine that connects yourhouse to your internet service provider The network operates on a topology and protocols, however if you wish to connect to the internet, you will need a modem

- Modem operation theory: To function and transmit Wi-Fi in the region of usage, our computer must be connected tothe internet via modem from our internet service provider This modem will be linked to the Internet connectionsupplied by the network provider A modem can also function as a computer translator Because computers onlycomprehend the language of 0's and 1's, the modem will modulate the signal into the computer's language The signalwill then reach the IP hub and be converted to digital form This digital can readily flow across telephone lines after ithas been modified Afterwards you may access the internet You can obtain a high-speed internet connection from the

provider by increasing the number of access lines and updating the modem technology

3.2 List network devices [6]

• Switch: A switch is a network device that links local area network devices (LAN) It scans data packets' destination MAC addresses and sends them to the appropriate port, letting devices to connect directly and effectively Switches are vital or network connectivity and come in a variety of sizes and configurations

Figure 11 Switch (source: vienthongxanh.vn)

Router: is a network device that links various networks and routes data packets based on the destination IP address Itincludes security measures as well as network address translation Routers are required for device connection via the

Internet and are utilized in many networks for connectivity and security

Figure 12 Router (source : www.asus.com)

Access point: An access point is a device that allows devices to connect wirelessly to a wired network It expands awireless network's coverage area and relays data packets between the wireless device and the wired network Wireless

access points are extensively utilized in various networks to enable mobility and flexibility.

3.3 List server types: [5]

- Web server: A web server is a computer system or software program that uses HTTP or other web protocols to provide web content and services over the Internet It provides static and dynamic information and may be used in conjunction with web apps to create a variety of services Web servers are required for the transmission of web content and services

Databases server [4]: A database server is a system or program that offers database services such as data storage,management, and retrieval It supports a variety of DBMS and database types and may be installed in a variety of ways.Database servers are required for data management and storage in a variety of applications and contexts.

Discuss the inter-dependence of workstation hardware with relevant networking software.

Explain what is meant by interdependencies: Interdependence refers to interactions between distinct components or parts of a system in which changes in one component effect changes in other components Interdependencies exist in complex systems and project management, and managing them needs planning, communication, and collaboration to minimize undesirable consequences and limit risks

Give examples of interdependency: Examples of interdependencies include a manufacturing process in which the efficiency of the production line is dependent on the availability of resources, a software development project in which tasks rely on each other, an ecosystem in which species rely on each other for survival, a supply chain in which timely delivery is dependent on various components, and a financial system in which the stability of institutions is interdependent

Define workstation hardware: Workstation hardware is a term that refers to computer components and peripherals that are designed for use in professional and technical applications Workstations are more powerful and adaptable than regular desktop computers, with features including faster CPUs, more storage space, and dedicated Graphics Specialized peripherals tuned for high-quality output and accuracy may also be included Workstation gear is built to fulfill the high performance demands of professionals and organizations

Define networking software: A combination of programs and applications that enable communication and data exchange across different computer systems and devices in a network is referred to as networking software It consists of protocols, services, and tools that enable network functions such as file sharing, remote access, security, and administration Network operating systems, monitoring tools, and security software are all examples of networking software Networking software is required for effective and secure network communication and data transmission
