, that are used in the same layer. Here, we define the agreement between the upper and lower layers and the same layer as the "internal protocol". Internal protocols are rarely involved in networking, and are mainly provided to network developers. If you're just trying to set up a network, don't bother with internal protocols.

The external agreement is the protocol that we must choose when we set up the network. Because it is directly responsible for the mutual communicati
In the previous issue, we introduced the familiar TCP/IP protocols and the content of IP, IPv6, and TCP Protocols. This section describes the IPX/SPX protocols closely related to Netware servers and games, as well as the IPX routing protocol and SPX protocol.

In his recent LinuxPlumbersConference2008 keynote speech, he bluntly accused Canonical, the company behind the Ubuntu community, of making minor contributions to the Linux community, especially in terms of kernel. In his speech, he pointed out that the Ubuntu community has contributed very little to the kernel. In the past five years, only about 100 Kernel patches have been submitted. At the same time, L

In the following years, developers adopted the RPM package management approach and introduced YaST, an easy-to-use graphical system management tool. With the frequent release of openSUSE, excellent print documentation, and the easy availability of SUSE Linux in stores in Europe and North America, SUSE Linux is becoming more and more popular.SuSE Linux was acquired by
In some online games, some may know the IPX/SPX compatibility protocol. So today we will focus on introducing this protocol. Next let's take a look at the main content. I hope this will help you.

When we are playing games between networks, do you know what protocols are implemented? This is the IPX/SPX compatible protocol we will introduce to you today. Of course, this agreement includes two meanings. First, let's take a look at them separately.

By the way, it is best to prioritize the use of twisted pair wires to connect devices to the Internet, because it is easy to install and the price is low.
