Discuss the benefits and constraints of different network types and standards.1 Define Network A computer network is a system that connects many devices to share resources and communicate with each other. It enables data transmission and sharing of information between devices. It is done within the network, regardless of their physical location.2 Network Types - A local area network (LAN) is a collection of devices that are interconnected at a physical location, such as a building, office, or home.
LANs can be small or large, from a home network with users to a business network with rows of users and devices in the office or school. Performed Student: Ngo Van Tin 2 Figure 2.Local area network(LAN) [2] Benefits: Simple and Inexpensive: The main benefit of a Local Area Network is that it is quick and easy to set up for a relatively low price. If an organization wants to build a network at a low cost and flexibility, a local area network would be an ideal choice. Accessible Software: Programs can also be shared on the Local Area Network.
Combine a single licensed program and any device can use it on the network. Fast communication: Devices linked to the LAN transfer files and communicate di- rectly and quickly based on the LAN model and installed ethernet cable. They work on 1000 Mbps, 100 Mbps and 10 Mbps. Gigabit Ethernet technology is evolving rapidly.
If the technology becomes complex and mass-produced, lower-cost vari- ants will become accessible to the masses. Client and Server Association: All company related information is kept on one server. If a customer requests information, the customer can seamlessly access that information. Resource collaboration: Expensive components, like scanners and printers, cannot be connected to every device in the office and it becomes a heavy task for the or- ganization, but in a LAN, requires a printer and scanner.
and people can be con- nected and they have to send instructions from their respective machines. This will save staff time and money. File Locking: A LAN allows locking files within its network. Drawbacks: Weak data protection: Unauthorized users can access files if the server has not been programmed properly.
Therefore, malfunctions are frequently observed. Maximum Damage: If a device, file, or server goes down, it affects the entire net- work. Expensive Installation Fee: Installing a LAN is expensive because it requires spe- cialized software to install the server. Malware: Malware can easily penetrate the LAN, corrupt the whole network, and destroys important data.
Performed Student: Ngo Van Tin 3 Maintenance: LAN requires frequent maintenance and the involvement of techni- cians and system operators. Space Issues: LAN software requires an area of memory in each mainframe used on the network. It minimizes the space required for the user's program. - Wide area network (also known as a WAN) is a large information network that is not constrained to one location.
A WAN can facilitate communication, information sharing, and more between devices from around the world through a WAN provider.Wide area network(WAN) [1] Benefits: Share Resources: The primary benefit of WAN is the ability to connect multiple of- fices, branches, and data centers around the world. This enables businesses to share resources, data, and applications with each other, eliminating the need for expensive and time-consuming physical connections between each location Scalability and flexibility: A WAN can easily scale up to meet increased bandwidth requirements in a short period of time. This means that organizations can instantly increase bandwidth as needed without having to install new equipment. Cost reduction: A WAN is significantly less expensive to implement than a private network.
This makes WANs cost-effective for connecting remote offices and in- creasing bandwidth. Improved security: Data transmission across a WAN is more secure than LAN- based transmission because most WANs use public networks. Performed Student: Ngo Van Tin 4 Acess to a wide range of service: Since WANs use the internet, organizations can access a wide range of networks and services. Drawbacks: Increased latency: Since data is transmitted over a WAN, there may be an in- crease in latency.
This means that it may take longer for data to travel across the network. Higher costs: Because WANs use a public network, they may come with a higher price tag than a private network. Security risks: While WANs are generally more secure than LANs due to the use of TLS, there are still some security risks. For example, employees may not use TLS properly, which can open the network to hacking.
Slower Issue: WANs are often slower than LANs due to the increased distance be- tween locations. This can affect the performance of applications and services that are hosted on the WAN. Complexity: WANs require complex network configurations and specialized hard- ware, which can be difficult to set up and maintain. Additionally, WANs are vulnera- ble to outages and disruptions due to their reliance on the public Internet.
This can cause data to be lost or delayed, which can be costly for businesses - The term MAN full form is a metropolitan area network. It is in between LAN and WAN technology and that cover the entire city. It is very similar to LAN technology. Here this article gives information about the advantages and disadvantages of MAN to know more details about it.
Performed Student: Ngo Van Tin 5 Figure 4.Metropolian area network(MAN) Benefits: It provides higher security compare to WAN It is wider than LAN It helps in cost-effective sharing of common resources such as printer etc It help people interface fast LANs together. This is due to easy implement of links MAN require fewer resources compare to WAN. This saves the implementation cost The dual bus used in MAN help the transmission of data in both direction simultaneously It provides a good backbone for a large network and also provides greater access to WAN A MAN is usually encompasses several block of city or an entire city Increases the efficiency of handling data Increases the speed of transfer data Easy to implement link Save the cost attach to establish a wide area network Drawbacks: More cable require for a MAN connection from one place to another The data rate is slow compared to LAN It is difficult to make a system secure from hackers The large network difficult to manage It is difficult to secure the network once its becomes large Network installation require skilled technicians and network administrators. This increases overall installation and management costs Cost is higher than LAN While we move our network to another city or area it doesn't work 1.3 Protocol and Standardsu 1.1 Network protocol definition: Network protocols are a set of rules outlining how connected devices communicate across a network to exchange information easily and safely.
Protocols serve as a common language for devices to enable communication irrespective of differences in software, hardware, or internal processes. Performed Student: Ngo Van Tin 6 Figure 5.2 Types of Network Protocol: Different protocols serve different functions to ensure efficient, quick, and secure net- work communication. Various types of network protocols can be categorized into the following three broad categories to help organizations operate seamlessly across dif- ferent business scenarios: - Network Communication Protocols: These protocols determine the rules and formats to transfer data across networks. Communication protocols govern various aspects of analog and digital communications, such as syntax, authentication, semantics, and er- ror detection, among others.
Some key network communication protocols include: Hyper-Text Transfer Protocol (HTTP) Transmission Control Protocol (TCP) Internet Protocol (IP) User Datagram Protocol (UDP) File Transfer Protocol (FTP) - Network Security Protocols: These protocols ensure safe data transmission over the network connections. Network security protocols define the procedures to secure data from any unauthorized access. These protocols leverage encryption and cryptography to safeguard. Here are the most widely used network security protocols: Secure File Transfer Protocol (SFTP) Hyper-Text Transfer Protocol Secure (HTTPS) Secure Socket Layer (SSL) - Network Management Protocols: Network managers require standard policies and procedures to manage and monitor the network for maintaining smooth communica- tion.
Network management protocols ensure quick troubleshooting and optimal perfor- mance across the network. The following are essential network protocols manage- ment: Simple Network Management Protocol (SNMP) Performed Student: Ngo Van Tin 7 Internet Control Message Protocol (ICMP) 1.3 Some common Network Standards: - International Organization for Standardization (ISO) - Wi-Fi Alliance (WFA) - International Telecommunication Union (ITU) - Internet Society (ISOC) - Storage Networking Industry Association (SNIA - IT Infrastructure Library (ITIL) - European Union (EU) 2. Explain the impact of network topology, communication, and band- width requirements. Topology or Network Topology is simply a network topology model.
This model clearly shows each hardware element, their arrangement. On the other hand, network topology is also understood as a way of connecting nodes in the same network. To optimize the operation of the network system. The physical network connection structure (most commonly LAN) is divided into sev- eral categories.
In which each network structure owns the configuration of each differ- ent node. For enterprises, the ideal network structure or not depends on the aspect of scale, investment cost and purpose of use. Each network structure model diagram is the basis for network administrators to moni- tor and support the maintenance and repair process of the network system.1 Types of Network Topology The structure of a network can directly impact its functioning.
