programs to configure a separate machine. Each program has a unique NetBIOS name. Each pc supporting applications also has a user-defined or internal NetBIOS site name. NetBIOS can contain up to 16 alpha letters. In the entire resource routing network, the combination of letters must be unique. Before a PC using NetBIOS can fully work on the network, the PC must first register the NetBIOS name. Take a closer look at the following. Start a machine ~~ What is he doing ?? When Client A is active,
default, a vro does not forward broadcast traffic. Therefore, it can be used to separate broadcast domains. Creating a broadcast domain with a vro reduces the broadcast traffic and provides more bandwidth for unicast communication. Each vro port is connected to a separate network, broadcast traffic is limited to the lan cidr block where the broadcast is sent. However, there are usually few vro network interfaces (

4. About the AddressIn the TCP/IP protocol, two pieces of information are used to locate a specified program: Internet address and port number, range 1-65535. The former is used by the IP protocol, which is parsed by the transport Protocol (TCP/UDP).Internet addresses are made up of binary numbers in two forms: IPv4 (32-bit) and IPV6 (128-bit). For ease of use, the two versions of the IP protocol have different representati
