Why don t I get started with LAN when I first learned about LAN?

In order to give a complete definition of a LAN, two approaches must be used: one is a functional definition and the other is a technical definition. The former defines a LAN as a group of desktop computers and other devices that are physically separated from each other by physical addresses and are interconnected in a way that allows users to communicate with each other and share computing resources such as printers and storage devices.

This definition applies to LANs used in office environments, factories, and research facilities.

In terms of the technical definition of a LAN, it is defined as a network system of computers interconnected by specific types of transmissions (such as cables, optical cables, and wireless**) and network adapters (also known as network cards) and monitored by a network operating system.

The distinction between functional and technical definitions is clear, with functional definitions emphasizing external behaviors and services; The technical definition emphasizes the material basis and method of composition required to form a LAN.

The name of the local area network (LAN) itself implies the locality of the geographic scope of the network. Due to the limitations of the smaller geographical range, LAN usually has much higher transmission rates than wide area networks (WANs), for example, the current LAN transmission rate is 10MB S, the FDDI transmission rate is 100MB S, and the backbone speed of WAN is currently only 64Kbps in China, and the end user's on-line rate is usually .

Currently, the topologies of LANs are commonly used as bus type and loop type. This is due to the limited geographical scope. These two structures are rarely used in WAN environments.

LAN also has a variety of features such as high reliability, easy scalability, easy management, and security.

First of all, you need to understand the classification of LANs, such as mesh. Stellate. Then there is the law of the IP address of the LAN to the extension and the setting of the IP address, which is the soft aspect, and the hard aspect is the connection of the machine, the cat, and the switch.

Two computers, one broadband ADSL port, how to form a local area network? The author has connected to the simplest LAN in the apartment, and I would like to share my experience with you.

Step 1: Hardware connection.

These two computers, one with Windows 2000 and the other with Windows 98. Meter with Windows 2000 installed.

The computer is the host, and the computer with Windows 98 is the customer.

Machine. Install two NICs on the host and one NIC on the client. One NIC on the host is connected to the broadband ADSL port, and the other is connected to the NIC on the client.

The connector of the network cable connecting the main machine and the client should be reversed (when purchasing, it is told that it is an intranet cable, and the connector is made by the computer parts seller).

Step 2 NIC settings.

The internal NIC connected to the client on the host is configured as the assigned broadband IP address, and the external NIC connected to the broadband ADSL port is configured as the assigned broadband IP. Set the client network card to IP and gateway. Set the external NIC connected to the broadband ADSL port in the host to Internet sharing.

Step 3 Workgroup setup.

Right-click the "My Computer" of the host, there is a "Properties" column at the bottom of the pop-up drop-down menu, click "Properties", you can see the "Network Identity" in the pop-up "System Characteristics" interface, click "Network Identity", you can see the workgroup to which the host belongs. If you didn't have a workgroup set up before, you'll see the default workgroup that reads: Workgroup:

workgroup”。Right-click "Network Neighbor" on the client's desktop, click the "Properties" bar at the bottom of the pop-up drop-down menu, you can see "Logo" in the pop-up "Network" interface, click "Logo", enter "workgroup" in the "Workgroup" that appears, and the host and client will be in a workgroup. It is also an essential step.

Easy to connect, no need for gateway software SYGATE, Winroute, no need to add a hub, no need to spend a long time groping, 10 minutes to get it. The operation is convenient, and after the host is connected to the Internet, the client only needs to log in to the host. The Internet access speed on both computers is not slow, and you can watch online TV, and the effect is good.

Simulate real-world environments with VMware Workstation.

LAN server can use win2003

For other PCs, select Win2003 to install XP DNS network management

It's not easy to set up a local area network? Geographical space constraints, expensive hardware equipment, professional and technical personnel? No, no, no, the cloud area network says:

It's so simple! As long as you have an internet connection, I can help you easily connect devices from all over the world into one or more LANs!

It's good to put it into practice. and know the basics of words. If you go to an Internet café and practice, you will understand it immediately. Computers are this thing. Or practice for living. Books are definitely going to be read. The Internet café should be a representative of the local area network.

Quitting evil is not self-protection, there is no way, natural art is not true, even if there is skill without compassion, evil deeds cause and effect hell gate. Be wise and read the writings of the sages, and do good deeds according to reason. Quit killing and releasing life to benefit sentient beings, auspicious and happy.

If you need to apprentice to a teacher, you can't do it without the guidance of good knowledge, and your thoughts are often reversed, and you can't distinguish between the Dharma and the illegal, only the arhats and above can do it, the apprentice is for, the teacher has a heritage, there is the Fa-rectification, there is a bright light, you won't run the wrong way, as long as you go along the way, whether it's fast or slow, the result is bound to reach the destination. In the absence of a monk, it is not impossible for a layperson to be a layman, but it is not the most ideal.

Apprenticeship is a good deed in itself, how can you talk about money and giving yourself. If you have a relationship with any master. Naturally, they will take you. If that master thinks so, then he is not worthy of being a master.

If your understanding is good enough, then you can choose self-study, if you think it is not good, then often go to worship the Bodhisattva, for the apprentice, then it is best to choose the Taoist monk, otherwise, it is also half a bottle of vinegar, which is not good.

Now the Taoist priests are controlled by the Taoist Association, you can go directly to the Taoist temple to apply for a job or be headed by the Taoist Association in your area, if you want to learn by yourself, it is difficult to be excluded without connections and resources.

Nowadays there is no true teacher, only false path. If you learn the Tao sincerely, first learn to be a person, be a kind person, an upright person, and a selfless person in your heart, and then learn the Tao, and there will be a teacher to take you in.

If the teacher is in the heart and has good thoughts in the heart, it is natural to meet the teacher.

When you have nothing to do, read through the I Ching and Lao Tzu, and I believe you will gain something.

Honor your parents more, respect the elderly is better than worshipping any teacher, and there will be a teacher to accept you. Trust me, and even more so in yourself.

Taoism is natural, nature is your real master, what you need is not a master but a heart to let go of attachment! Taoism and Buddhism are the same in this regard!

The superior is not necessarily in the mountains. There may not be a master on the mountain. You can practice the Fa without being superstitious.

Isn't it easy to worship the master? For example: get started with hairdressing, learn from a barber teacher, and start from scratch

Recite the Tao Te Ching first, and then find a Taoist temple to practice.

Let me tell you, the small is hidden in the wild, the big is hidden in the city, go to the vegetable market and cultivate the Tao, sell rice noodles or something.

Simple, first of all, you have to know how to connect the network cable, and then you have to know the computer structure, and then you have to figure out the type of network you build, how many machines are connected, and then you have to learn the network protocol, and finally connect it, set it up, and then read it again.

You're a big question, and I'm studying. However, it is recommended that you search on the Internet when you encounter a problem, and you should find where your problem is, and if you can't find it, buy a book to read, hehe, I will now deploy the local area network of the school's office building.

LAN knowledge lectures.

I can only borrow flowers to offer Buddha.

Layer 3 switching is only used in enterprise-level networks, and the general small and micro enterprises are at most Layer 2 and Layer 3 switching private line access, with at least a few public network IPs.

The first layer of the Internet café networking can be used, with nat**.

There are many tutorials available online. Search for it.
