I.Discuss the benefits and constraints of different network types and standards 1.Network In information technology, a network is defined as the connection of at least two computer systems, either by cable or wireless connection. The simplest network is a combination of two computers connected by cable. This type of network is called a peer-to-peer network. There is no hierarchy in this network; both participants have the same privileges. Each computer has access to the other's data and can share resources like disk space, applications, or peripherals (printers, etc.). Networks today tend to be a bit more complex and consist of more than just two computers. Systems with more than ten participants typically use a client-server network. In these networks, a central computer (server) provides resources to other participants in the network (client). 2.Network types a.Local Area Network (LAN) Definition LAN (Local Area Network), also known as a local area network, is used in a limited area with high transmission speed. Figure 1 Working model of LAN
Devices using LAN can share resources with each other, typically sharing files, printers, ... and some other devices. Advantages High transmission speed, support to connect many devices quickly. Although limited in connection range, it costs less, uses less wires, and is easy to administer. b.Metropolitan Area Network(MAN) Definition MAN (Metropolitan Area Network), also known as urban network, links from many LANs via cables, other transmission means. The ability to connect in a large range such as in a town or city , the provincial. The MAN network model is often used mainly for organizations and businesses with many branches and departments connected to each other. Figure 2 Network connection MAN 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), deploying applications easily. . Advantages The large connection range makes interaction between business parts easy, efficient, low cost, stable transmission speed, information security, simple management. c.Wide Area Network(WAN)
Definition 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. Figure 3 WAN connection 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 Large connectivity, no signal limitation, easy information sharing, data storage. Relative transmission speed varies by region or transmission device. 3.Network protocol A network protocol is a set of established rules that define how data is transmitted between different devices in the same network. It basically allows connected devices to communicate with each other, regardless of any differences in their internal processes, structures or designs. Network protocols are the reason you can easily communicate with people around the world and therefore play a vital role in modern digital communication.
