Basics of Networking

IP ADDRESS (Internet Protocol)

Definition:  A numerical value that been assigned to a device/computer/node in order for it to join/participate/communicate in a network. IP address only has a valid combination of number 0 – 255 (which consist of 256 digits as 0 is also counted)

IP address must be unique in each device/computer/node and cannot have a duplicate in the same network. IP address usually is represented in dotted-decimal notation for example 112.243.137.100

IP address is divided into 2 purposes; one is for external (normal use) and internal (private network, localhost). The internal IP is only usable within the Local Area Network (LAN).
