(M1) Performed Student: Nguyen Trinh Anh Tuan CHAPTER 1: BASIC KNOWLEDGE LO1: Examine networking principles and their protocols I. (P1) Discuss the benefits and constraints of different network types and standards. What is network? 1. -A network could be a system consisting of many computers (at least 2 computers within the same system) that are connected to every other through physical transmission lines in line with a particular structure.
-The function of a network is to form data exchange and resource sharing between computers within the system easier without using external devices like USB, memory cards, and disks. CD… -A complete electronic network system will include the subsequent parts: Terminals, transmission medium, physical connection equipment, and connection software. -Terminals: Computers, phones, printers, scanners, cameras, etc. are all terminals in an exceedingly network.
These devices are going to be connected to every other through connecting devices or transmission mediums. -Physical connection devices are devices like wires, modules, switches, etc., that are directly connected from one terminal to a different one. -Connection software: kind of like the transmission medium, connection software is the program and application installed on the terminal devices and has the function of sharing data over wireless transmission lines. -There are four common styles of computer networks today: LAN, MAN, WAN, and PAN.
Below, we are going to share thoroughly each kind of network. -Metropolitan Area Network (MAN Network) -Wide Area Network (WAN Network) -Local Area Network (LAN Network) Figure 1 Define Network Client -The client-server model (client-server network model) is a distributed application architecture. It partitions tasks or workloads between resource or service providers, called servers, and service requesters (Clients). In the Client-Server architecture, when the Client sends a request for data to the server over the Internet, the server accepts the requested process.
Then send the requested data packets back to the client. Clients do not share any of their resources. -When it comes to Client, it means a person or an organization that uses a particular service. The same is true in the digital world.
Client is a computer (Host), ie capable of receiving information or using a specific service from service providers (Server). Peer to peer (P2P) -A peer to peer (P2P) network is a distributed application architecture that partitions tasks or workloads among peers. Peers are devices participating in the application with equal privileges. They form a peerto-peer network of nodes.
-Peers make a portion of their resources, such as processing power, disk storage, or network bandwidth, available to other participants without the need for central coordination of a stable server or host. Peers are both providers and consumers of resources. It differs from the traditional client-server model in that resource consumption and provision are split. -Previously, the peer-to-peer system was used in many application areas.
This architecture was popularized by the file sharing system Napster, released in 1999. This concept has inspired new structures and philosophies in many areas of human interaction. In such a social context, peer-to-peer as a meme refers to the egalitarian social network that has emerged throughout society, enabled by Internet technology in general. Performed Student: Nguyen Trinh Anh Tuan 1.2 Network type (MAN, WAN,LAN etc.) LAN -LAN stands for Local Area Network, roughly translated as local computer network, this interface allows computers to connect to each other to work together and share data.
This connection is made via a LAN cable or Wifi (wireless) in a narrow space, so it can only be used in a limited range such as offices, homes, schools. -LAN has great significance in today's modern life, any company, organization or individual who wants to manage internal data, or connect and communicate with each other must be through LAN. LAN helps mobile devices such as phones, laptops, tablets easily connect and access the internet at any time Benifit -High speed. -Can run large online applications thanks to strong bandwidth -Cheap and easy to manage Constraint -Can only transmit in a certain space because the transmission line is short.
Man MAN (Metropolitan Area Network), also known as an urban network, links many LANs via cables, and other transmission means,. The ability to connect in a large range such as in a town or city is conscious. The MAN network model is often used mainly for organizations and businesses with many branches and departments connected to each other. Man network is often used for businesses because this model provides many types of services such as connecting lines via voice (voice), data (data), video (image), and deploying applications easily.
- Advantages of MAN network. The large connection range makes the interaction between business parts easy, efficient, low cost, stable transmission speed, information security, and simple management. Benefit: Can connect with high speed up to 1Gb/s to run the state, change information, develop ecommerce. Popular with large bandwidth needs in big cities like Hanoi and Ho Chi Minh City -There is a wide variety of services, maximized on modern bandwidth, service by providing service in the present and in the future, improving the broadband network service will be highly profitable network.
Constaint: Complex management High cost The connection is quite large Have average bandwidth to run banking operations Wan -WAN (Wide Area Network), also known as wide area network, is a combination of urban networks including MAN and LAN through satellite equipment, optical cables, and power cables. Wide area network was created to connect on a large scale across the country. The protocol used in the WAN is TCP/IP, the bandwidth varies depending on the installation location. - Advantages of WAN Large connectivity, no signal limitation, easy information sharing, data storage.
Relative transmission speed varies by region or transmission device. Benifit: It can both connect to private networks and create connections on a global scale. Can transmit signal over long distances and unlimited. User access rights can be controlled.
Information can be shared easily and quickly. Constraint: Performed Student: Nguyen Trinh Anh Tuan Weak connection because of low bandwidth. High installation cost. Difficult to manage.3 Benefit of the network -The Internet is extremely important and brings a lot of benefits to the entire global humanity.
The Internet makes information transfer quickly, you can access information on the internet at almost any location on the globe. For the sake of simplicity, to summarize the internet has the following benefits: -Look up and learn a huge store of information online -Help people do business, sell online, make money and increase jobs -Linking friends and relatives through social networks like Facebook, vegetable garden Zalo -Send and receive mail, read online news -Watch movies, listen to music online, play games -Using social networking apps… 1.4 Protocol and Standards Network Protocol Definition -The protocol is a rule file that defines how to format, transmit, and receive data so that network computers - from servers and routers to endpoints - can communicate with each other, regardless of any differences in the base layer, design, or standard facilities. To send and receive data successfully, devices on both sides of a communication exchange must accept and follow protocol conventions. -Network protocol support can be built into the software, hardware, or both.
Standardized network protocols provide network devices with a common language. Without them, computers would be unable to communicate with one another. As a result, except for networks explicitly designed for a specific architecture, only a few networks can function, and the internet as we know it today would not exist. To communicate with one another, almost all end-users rely on network protocols.
Network Protocol Definition -Internet Protocol Suite is also referred to as Internet Protocol Suite. This protocol may be a collection of protocols that implement the protocol stack on which the web runs. -This protocol also can be called TCP/IP protocol. they're all important protocols within the Internet Protocol Suite.
TCP - Transmission Control Protocol and IP - Internet Protocol. And it can even be understood that Internet Protocol Suite is analogous to the OSI model, but there are differences between them, but not precisely the same. In layers (layers), not all layers correspond well. Protocol Stack -Protocol Stack may be a kind of software implementation for a group of network protocols.
they're a full set of protocol layers that they work together to supply network connectivity to other devices. Transmission Control Protocol (TCP) -Transmission Control Protocol (TCP) could be a transport control protocol. they're the core protocols of the net Protocol Suite. With the task of implementing the network, complement the net Protocol.
This protocol ensures reliable and in-order delivery of information to the destination. TCP also provides a way for reliably delivering an octet stream. As an 8-bit data block stream, TCP also distinguishes between data from many various applications. File Transfer Protocol (FTP) -File Transfer Protocol (FTP) – File transfer protocol.
and therefore the direction won't be to exchange files over a communication network using the TCP/IP protocol. FTP's default port is 20/21.
