SERIAL port", as shown in 7.
This port is mainly used to connect to network connection modes such as DDN, Frame Relay, X.25, and PSTN. Sometimes DDN or X.25 or other WAN connection technologies are used for leased line connection between enterprise networks. This type of synchronization port generally requires a very high speed, because in general, both ends of the network connected through this port require real-time synchronization.4) asynchronous serial portAsynchronous Serial Port (ASYNC) i
will analyze several state changes (SRC, Bri, DST) in this tower deformation to indicate:
(1 ~ N, 0, 0) --> initial state
(N, 0, 1 ~ N-1) --> move n-1 plates from SRC to DST (first send to Bri and then send to DST)
(0, N, 1 ~ N-1) --> move the nth plate from SRC to Bri
(1 ~ N-1, n, 0) --> move n-1 plates on DST back to SRC

There are more types of synchronous serial ports that can be supported in routers, such as Cisco Systems that can support 5 different types of interfaces, namely eia/tia-232 interface, eia/tia-449 interface, v.35 interface, x.21 Serial cable assembly and EIA-530 interface, corresponding to the adapter. It is important to note that, generally speaking, the adapter line ends with a different shape (g

Because the connection speed of the Internet access method such as ISDN has its own unique side, at that time, when ISDN was just emerging, it had been fully applied to the Internet connection mode. The isdn bri port is used to connect an ISDN line to the Internet or other remote networks through a

Assume that the read request is sent to datanode I and Its Replica status is (Bai, Bri)
If off + Len
If off + Len> Bai, it is because off + Len
Off + Len cannot be greater than bri.
If DNI goes down during service, the DFS client switches to another datanode containing replica.

ISDN is an abbreviation for the English "Integrated Services Digital Network", or "Integrated Services Digital Network".
Integrated Services Digital Network evolved from a telephone integrated digital network to provide End-to-end digital connectivity to support a wide range of businesses, including voice and voice services, to provide users with a standard set of multipurpose user-network interfaces. In short, it is a network, namely a set of transmission equipment and a set of switching equip
Yesterday, Weibo saw a question in the 1 million Usernames. try to find the username automatically created by the machine. It is actually a simple anti-spam method. Some people say that they can search by google or baidu for each user name to see if there are any traces of Internet access. Not to mention that this is unreliable. The author obviously wants to solve this problem from an algorithm perspective rather than social engineering. I began to th
