We know that IPTables acts according to rules. Let's talk about rules. Rules are actually predefined conditions for network administrators. Rules are generally defined as "if the packet header meets such conditions, this packet will be processed in this way". The rules are stored in the packet filtering table in kernel space, specifying the source address, destination address, transport protocol (such as TCP, UDP, ICMP), service type (such as HTTP, FTP, and SMTP), and so on. When packets match the rule, iptables processes these packets according to the methods defined by the rule, such as accept, reject and drop. The main task of configuring a firewall is to add, modify, and delete these rules.
The above has already given detailed examples and described how to manage IPTables rules. In order to review quickly in the future, we will summarize the above commands.

Intel's current processor development mode is "Tick-Tock", which also updates the microarchitecture (Tock) every two years and alternately upgrades the production process (Tick). Nehalem is a new architecture using 45nm process, while Westmere will be upgraded to 32nm in 2009 and Sandy Bridge in 2011. According to the latest intelligence, Intel will launch "IVY Bridge" in April 2012, which is Sandy Bridge's 22nm process upgrade. In 2013, "Haswell" was launched again, another new architecture based on 22nm process. Now it can be basically confirmed that Intel's next stop after 22nm will stay at 15nm. There is already a lot of evidence to prove this point. It is said that TSMC is the same. However, there are also statements that mention different nodes such as 16nm and 14nm, and IBM/AMD's plan is 16nm. It should be 11nm in the future, but Intel has also mentioned 10nm on different occasions. It seems that the distant future is still full of unknowns. In terms of code name, some people said that the 22nm Haswell in 2013 should be followed by Rockwell. According to the convention, the architecture will remain unchanged and the process will be upgraded. However, SemiAccurate website today
