Learning notes-transmission of TCP/IP protocol, learning notes-tcpip Protocol1. Data Transmission over the network can be divided into two types: connection-oriented and connection-free:1.For connectionless protocols, such as Ethernet, IP, and UDP. 2. For connected protocols, such as ATM, frame relay, and TCP. See the following figure:
Connection Oriented

1. Architecture and main protocols of TCP/IP protocol family
The TCP/IP protocol family is a layer-4 protocol system.
Data link layer: implements network drivers for Nic interfaces to process data transmission on physical media (such as Ethernet and Token network. The two common protocols on the data link layer are ARP (Address Resolve Protocol) and RARP (Revers Address Resovle Protocol ). Converts IP addresses to phys

The TCP/IP Protocol is not a single TCP Protocol or an IP Protocol. It is a group of protocols, including TCP and IP Protocol, UDP Protocol, and ICMP Protocol) protocol and other protocol groups (a set of protocols). When you call them, they are collectively referred to as TCP/IP.2. overall architecture

After testing by the author, the ADB service is possible (this service can be found in the Windows process, which is used for the emulator or a real-time service connected via a USB cable), after the simulator has been running for a while. The ADB service needs to be re-closed and restarted. Of course, restarting eclipse may solve the problem. But that's more troublesome. If you want to close the
