Common network name

Workstation, a common network name, can be said to be a Workstation for any machine that can provide input to the network environment. Its main definition element is "input ". This can include personal computers, hand-held scanners, terminals, and so on. Each workstation has its own network card. Each workstation, network fax machine, network printer, file server, or any other device with its own unique network address is a Node. How do they get the network address? Get it from the network card. Each network card is assigned an address by the manufacturer at the factory time. It is impossible for the user to change this address. The address arrangement such as www.2cto.com is the same as our daily home address, which is used to differentiate their identities. Your network must be able to distinguish this address from other addresses. In the network, many data packets are transmitted from one node to another, and the packets must be correctly transmitted to the destination, the destination must be identified by the network card address. From a technical perspective, a Server is a distribution center that has certain functions in the network. There are also several types of servers. For example, a printing server is a machine that allows a group of users to store columns and process printing; A fax server can accept fax requests, store columns, and process faxes. To create a printing server, you may need to leave a machine empty for processing only the printing service, or a printer with a network card. The most common server is the archive server. An archive server is a computer that stores and manages archives, applications and data, and is responsible for security services. It provides centralized control over your data and creates a common place for centralized backup of your files. Www.2cto.com (Packet) is the smallest unit of information that can be transmitted over the network. A package contains the sending End Node Address, the receiving end node address, and the data to be transferred between the two nodes. Network Topology involves the physical and logical relationships between nodes on the network. On the surface, it is the "long image" of the network ". You can view your network in two ways: physical and logical. The physical form of the network refers to the physical arrangement of each node on the network and the overall configuration of the nodes. If you mark the locations of each computer on paper and draw the network Cable (Cable) that connects them, you will see the physical form clearly. For example, bus, ring, or star ). The network logic pattern describes how information walks on the network. Let's take an example to simulate it so that we can better understand the logic form: www.2cto.com. If you have a 400-page file sent from Tainan to Taipei, and it must be delivered by tomorrow at the latest, then you are likely to use the Alibaba Cloud Express Service (assuming it has already been set up. However, to handle this transfer, you must also use the envelope and address volume marked by the courier on the Internet. At the same time, you must provide the address of the sender and recipient, of course, your 400 page file. On your network, the same information is required for transferring data from one computer to another: it requires your sending Address, receiving address, and data. As mentioned above, these materials are included in the package. The logic form takes over how the packet is transmitted over the network. 1. First, the logic form determines the format of the package, just as you must enter the address in the format of the address volume marked by the courier. You must use the address format that the network can understand. 2. The logical form determines how much data needs to be carried, just as the standard envelope can only contain up to 30 pages of files. 3. Then, the logic will determine the method used to track packets transmitted over the network. Some logic forms do not track packets, but assume everything is correct, and some track every step in the path. If you have heard of Ethernet or Token Ring, you have already come into contact with the logical form. Each logical form is often associated with the physical form of the network, but the physical form is not necessarily the logical form. For example, in physics, we can say that it is a Star network, but logically, it is probably a Token Ring Network. Www.2cto.com

Later, we will describe different logical forms, including their respective advantages and disadvantages. This is a very important question, because different network types will affect what type of network card you need to install on your network. In a complex network, there are several different types of network forms.
