The difference is: 1. The dial-up method is to access a network that can access the Internet through a Layer 2 encapsulation channel; 2. The LAN method is that the LAN already has other ways to access the Internet, and the hosts in the LAN also have access to the Internet. The right to access the Internet; 3. The dial-up method is generally used by remote users; the LAN method is generally used by local users.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
1, the dial-up method is to access a network that can access the Internet through a layer 2 encapsulated channel through technologies such as pppoe or L2tp;
2, the LAN method, the LAN already has Use other methods to access the Internet. As a host in the LAN, you also have the right to access the Internet;
3. The dial-up method is generally used by remote users; the LAN method is generally used by local users;
Extended information:
A local area network is naturally a regional network formed in a local area. Its characteristic is that the distribution area is limited, which can be large or small, as large as one building and adjacent buildings. The connection between offices can be as small as the connection between offices. Compared with other networks, the LAN itself has faster transmission speed, more stable performance, simple framework, and closed nature, which is why many organizations choose it. The local area network itself is generally composed of computer equipment, network connection equipment, and network transmission media. Computer equipment includes servers and workstations, and network connection equipment includes network cards, hubs, and switches. Network transmission media is simply Network cable is composed of three major components: coaxial cable, twisted pair and optical cable.
A LAN is a private network, typically within or near a building, such as a home, office, or factory. Local area networks are widely used to connect personal computers and consumer electronic devices, allowing them to share resources and exchange information. When LANs are used in companies, they are called enterprise networks.
A local area network connects various computers, external devices and databases in a certain area to form a computer communication network, and connects to local area networks or databases in other places through dedicated data lines to form a larger information processing system. LAN connects network servers, network workstations, printers and other network interconnection devices through network transmission media to achieve system management files, share application software, office equipment, send work schedules and other communication services.
The LAN is a closed network, which can prevent information leakage and external network virus attacks to a certain extent, and has high security. However, once an incident such as a hacker attack occurs, it is very likely to cause the entire LAN to be paralyzed. All work within the network cannot be carried out, and a large number of company secrets may even be leaked, causing serious damage to the company's business development. In 2017, the country promulgated the "Cybersecurity Law of the People's Republic of China", which officially came into effect on June 1. It clearly stipulates network security and information security from a legal perspective, and puts forward corresponding requirements for network operators and users. Improve the security of network use.
