ADSL is a very common broadband access method. However, since one user has only one ADSL account, how can we achieve multi-user sharing of ADSL? Here we will introduce the implementation method. ADSL is an affordable broadband access solution. Currently, it is billed on a monthly basis. if a user uses an account to access the Internet, it will be a bit uneconomical. How can one ADSL user access the Internet? The following are some experiences. Sharing principle: in view of the current mainstream

There are a variety of wireless Internet access methods. We often see wireless network interfaces and wireless network interfaces for wireless Internet access. For today's wireless trends, the wireless access of infrared seems a little retro. It cannot be said that it has been out of the stage, at least in terms of choice, it has gradually been forgotten by everyone. Next we will introduce a wireless Internet access solution through infrared rays. This method is based on GPRS traffic to access t

difficulty in understanding SRP is in the case of a multifunctional class, which is not easy to understand the contradiction between versatility and single change. Let's take a look at a modem class example, modem has 4 functions: dial-up, hang up, send data, receive data: class　Modem　{ 　　　　 public　void　Dial(string　aPno)　{…} 　　　　 public　void　Hangup()　{…} 　　　　 p

NAND Flash (k9f5608) Driver Programming 1. NAND Flash pins The important ones of NAND Flash are as follows: I/O pin: For this flash chip I/O pin, there are 8 0-7, and some chips have 16 0-15 CLE: instruction transmission enabling (the instruction can be locked in the instruction register of nand flash) Ale: Address Transmission enabling (the address can be locked in the Address Register of nand flash) CE: Slice selection, low efficiency 2. NAND Flash Control Nand Flash is controlled by transmitt

: J.ffs2_raw_inode and Jffs2_raw dirent. The former contains administrative information about the file , which is used to describe the location of the file in the file system . The real information is kept behind the Jffs2_raw_inode node, and most of the information that is managed is built after the system is mounted. Two data entities have a common file header structure JFFS2 _ Unknown_node. In this structure, there is a jint32 _t type of HDR_CRC variable, which represents the CRC checksum val

encapsulated chip is a chip 3. die is a small square on a wafer. Several die may be encapsulated in a chip. Due to different flash technologies and different technologies, the concept of die is generated. Mono die is a common concept, A die, B die, etc. A chip contains N die 4. plane is the smallest unit for NAND to operate based on commands such as read, write, and erase. A plane is a storage matrix that contains several blocks. 5. Block is the minimum erasure unit of nandflash. A block co

If the socket option So_oobinline (see Setsockop), the OOB data that appears will be checked. The parameter Writefds indicates that the socket is checked for its writable character. If the socket handles connect calls (non-blocking) and fully establishes the connection, the socket is writable. If the socke

[DESCRIPTION] in BT2.1 and later versions, the Bluetooth protocol has a new way of simply pairing (simple pairing) in addition to the traditional password pairing (PIN code pairing). This new pairing operation is simpler and more secure. At present, most Bluetooth devices in the market have supported the simple pairing method. From the user's point of view, the traditional PIN code pairing requires both sides of the Bluetooth device to enter the pairing password (if both sides have input devices

ADSL is an affordable broadband access solution. Currently, it is billed in monthly subscription mode. If a user uses an account to access the Internet, it will be a bit uneconomical. How can one ADSL user access the Internet? The following are some experiences.　　 Sharing principle　　 In view of the current mainstream Ethernet interfaces, the external ADSL Modem has built-in routers and routing functions, and also has a large-capacity ROM chip (includi

At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using ADSL to access the Internet, usually, an ADSL line can only support one computer to access the Internet, however, after using a networking device, you can implement an ADSL line to support Internet access shared by multiple computers. Generally, devices that implement the shared networking of ADSL include ADSL Modem, Broadband Router, an

wireless router, we have to do the physical connection operations related to the wireless router: First of all, the ADSL modem device is connected to the WAN port of the wireless router, and then the common twisted pair connects the LAN port of the wireless router with the normal workstation. After completing the physical connection operation, we go to the Windows system interface of the normal workstation and open the system's TCP/IP property Setti

Shanghai Bell Company's Cablelink Cable modem system provides high-speed asymmetric data communication services to users through the fiber coaxial hybrid network. The asymmetry of its connections requires high-speed communications in one direction, such as network browsing, Internet file transfer, and ideally in the opposite direction with a lower-rate delivery service. The TDMA access method used in Cablelink 2000 system can make the system more flex
