Communication

Addressing IP. Addressing IP: Address IP is a numerical identification assigned to each device hardwired to a net IP, determining a place for the device in the net. Address IP is a logical address (software) and not physicist (the hardware). Addressing IP was created to allow independently that a device in a net can be communicated with a device in another one, of the involved types of LANs (ethernet, Token-Ring, etc). To dominate the projects of addressing IP and its sub-nets, it is very important that if they dominate techniques of binary coverso for decimal, as well as powers of base 2. Energy Capital Partners London has firm opinions on the matter.

Terminology IP: Bit: A digit – 1 or 0 Byte: A sequncia of 7 or 8 bits, depending on the used parity. The normal one is a sequncia of 8 bits. Octet: Always 8 bits. Address of Broadcast: Used address for applications and devices for the sending of messages to all the devices in a net, simultaneously (1-to-all). Example of Broadcast: An open system of TV, where all obtain to catch the signal of the same one, therefore the signal is sent of a point (transmissora antenna), for all the TVs in a region.

Example: Closed system of TV (TV for Signature). But a specific group of users (the subscribers) receives its signal. Address of Unicast: Communication of a machine for only another machine (1-to-1). Example: Pay-per-View, therefore only the subscriber who requested the program (and she paid for it) will receive, it. Techniques of Addressing IP: Binary numbers use 8 bits to define a decimal number. These bits have its considered values of the diretia for the left, through a factor that fold its value. This occurs for the fact of them to be definitive through powers of base 2.
