The complexity of the language of Tex has been talked about a lot before, and the comp

represent different applications. T C P and U D p put the source port number and the destination port number respectively in the message header. The network interface sends and receives the I P, a r p, and r a r p data separately, so you must also add some form of identification to the Ethernet frame header to indicate the network layer protocol that generates the data. For this reason, the Ethernet frame header also has a bit frame type field. Seven Now we talk about

. Also, a network application can bind to the port it needs (such as the 53 port of BIND), but it cannot bind to other ports.The domain-type model means that each process running in the security domain and each resource (generic, directory, socket, and so on) has a "type" associated with it.On top of that, a series of rules are set up that lists all the actions that a domain can perform on each type. One advantage of the domain-type model is that we c

Web|web2 (Reprinted from http://www.klogs.org/archives/2005/07/nieweb_20_o.html ) History is very important. The study of a technology should also be based on history, through its evolution in the history of time, to know the status quo, and even to predict the future. What's the Web1.0? Do they say, remember the static HTML of the WWW era? (WWW application of that era, people's web experience, what's the impact on society?) ） So how many versions are

I have never seen such a fan in other languages that easily shows the ugly side of human nature, even the C ++ and C attacks that started more than a decade ago, when GC and non-GC are sprayed, static type dynamic type is sprayed, and even when the cloud wind is sprayed with C ++, the brain is not affected. This happens only to the brains of the go language.

Therefore, having the IDE hard disk and the main IDE CD-ROM device (such as a DVD burner), sharing the motherboard's only IDE interface, is a worthwhile solution. Non-major IDE optical drive devices (such as CD-ROM, DVD-ROM, etc.) can be removed for standby or sold on Taobao. Really need to use more than one optical drive users, ca
