Part of the Storage management glossary: A physical address is a binarynumber in the form of logical high and low states on an address busthat corresponds to a particular cell of primary storage(also called main memory), or to a particular register in a memory-mapped I/O(input/output) device.
A network address, or IP address, is a series of numbers that a computer or other device uses to connect to a network, like the internet. An example of an IP (or network) address would be 192.168.1.100. IP addresses are individual and differ between devices and networks. An IP address is separated into two parts. The first part is the network address, which is the first three series of numbers (192.168.1 as shown in the example.) The last number or series of numbers (100 in the shown example) is the host address.
