The SOCKS server is implemented at the application layer. The SOCKS client is implemented between applications and the (22) layer. When an application client

11、 needs to connect to an application server, the client connects to a SOCKS proxy server. The proxy server connects to the application server instead of the client, and (23) data between the client and the application server. For the application server, the proxy server is the (24) . SOCKS is also on

23、heritanceC.inferenceD.connectionNetworks can be interconnected by different devices. In the physical layer, networks can be connected by (41) or hubs, which just move the bits from one network to an identical network. One layer up we find bridges and switches, which operate at data link layer. They

24、can accept (42) , examine the MAC address, and forward the frames to a different network while doing minor protocol translation in the process. In the network layer, we have routers that can connect two networks. If two networks have (43) network layer, the router may be able to translate between th

As commonly used, a certificate also contains an (69) date, the name, of the CA that issued the certificate, a serial number, and perhaps other information. Most importantly, it contains the digital
