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.
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. Source: Tessa Espinola. 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. Address of multicast: Used address for only one machine to reach a definite group of machines (1-to-many).
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.
