<b>1.Introduction </b>

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:

<b>1 Discuss the benefits and constraints of different network types and standards.</b>

<b>1.1.Define network:</b>

A network is a collection of two or more computers or devices (such as servers, routers, switches, and other hardware) that are linked together to share resources, exchange data, and interact with one another.

</div><span class="text_page_counter">Trang 19</span><div class="page_container" data-page="19">

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.

+ 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.

</div><span class="text_page_counter">Trang 25</span><div class="page_container" data-page="25">

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.

<b>2.3.Communication and Bandwidth:</b>

• 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.

<b>3 Discuss the operating principles of networking devices and server types.</b>

<b>3.1.Discuss 1 or 2 operating principles of a selected network device </b>

- 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.

</div><span class="text_page_counter">Trang 61</span><div class="page_container" data-page="61">

- 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 signal

will 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.

<b>3.2.List network devices [6]</b>

• 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.

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.
