There are two laptops, One Mac and the other Windows 7 at home. Now we need to allow both computers to access each other's files, so we plan to create a point-to-point Wireless LAN. 1. Create a wireless network in the MAC system. First, enable the airport, that is, enable the wireless connection of the apple notebook. Open "system preference settings", click "

1. General A brief diagram of the network port structure. the network port consists of three parts: CPU, Mac, and PHY. the DMA controller is usually a part of the CPU. the dotted line is placed here to indicate that the DMA controller may be involved in data transmission at the network port. These three components are

Returns the media access control (MAC) address of all network adapters in the computer and the list of network protocols for each address, either from the local area or back through the network.

I read books related to network basics a while ago. I had a question: Why do I have a MAC address and an IP address? Can the two be combined into one? The current logic is as follows: During data transmission, the vro can view the IP address of the data packet and compare it with the "IP Set: Next Hop MAC address" recorded in the routing table, when the

Whether the same network segment can do the same IP and MAC address,In fact, you can completely change the IP of the two computers to the same as the Mac, not only the internet but also no IP conflict. This method can not only break through the routing blockade used in the ADSL shared Internet, but also can be used in the IEEE802.1X authentication environment, bu

These two days to modify the network card driver to achieve 10/100/1000m adaptive, so the next PHY chip and EMAC driver to the compatibility of 10/100/1000m network environment, recorded here. Network device-side Data link layer is composed of MAC Chip and PHY chip, PHY chip based on the external

I have previously compiled an access authentication article based on 802.1x protocol, which is a common method to achieve network security, but the premise is that the client needs to pass the corresponding media (authentication software) to achieve access authentication, so in case the customer does not want to bother so much and wants everything to be solved by the service provider, this is of course not a problem, today, I will introduce a user-fri

How mac and phy achieve network self-adaptation and macphy self-adaptationIn the past two days, the NIC Driver was modified to achieve 10/100/10/100 m self-adaptation. Therefore, we studied how the phy chip and the emac driver are compatible with the/M network environment, which is recorded here.The device data link layer in the

Figure 3 If you are online, you can also use the following method to check the MAC address: first start IE to connect to the network, right-click the

These two days to change the network card driver to achieve 10/100/1000m adaptive, so study the next PHY chip and EMAC Drive how compatible 10/100/1000m network environment, recorded here.The device-side data link layer in the network consists of a Mac chip and a PHY chip. The PHY chip is actively negotiated and config

We certainly don't know the MAC protocol. This Protocol defines the network address and is the foundation of our network. Now, we will give a brief analysis and introduction on this protocol, hoping to give you a deeper understanding of this Protocol. Meaning Media Access Control Meaning Media Access Control It defines how data packets are transmitted on the medi

These two days to modify the NIC driver to achieve 10/100/1000m adaptive, so study the next PHY chip and EMAC drive how compatible with 10/100/1000m network environment, recorded here.The device-side data link layer in the network consists of a Mac chip and a PHY chip, and the PHY chip is automatically negotiated and configured according to the external

Objective: To complete the network Port transceiver debugging process: NBSP;NBSP;1, network port initialization, according to the chip data sheet configuration 2, the number of network port, first to the TX FIFO in DM9000 to the data, and then sent to send the register to complete the sending; 3, network port recepti

A user station can be connected to a single user terminal (TE) or a User resident network (CPN) [2].Broadband Fixed wireless access network data transmission direction is two-way, uplink refers to the data transmission direction from the user station to the base station, the rate of 5.12 mbit/s, downlink refers to the direction of data transmission from the base st
