The length of an IPv6 address is 128-bits. The length of an IPv4 address is 32-bits, hence, we have 2 32 IP addresses available. To identify each device in the world-wide-web, the Internet Assigned Numbers Authority (IANA) assigns an IPV4 (Version 4) address as a unique identifier to each device on the Internet. Type “hostname” in the command prompt(Administrator Mode) and press ‘Enter’, this displays the hostname of your machine.Īlso known as the Logical Address, the IP Address is the network address of the system across the network.
UNIQUE IDENTIFIERS OF NETWORKĮach device in the network is associated with a unique device name known as Hostname. A few such protocols are TCP, IP, UDP, ARP, DHCP, FTP, and so on. It is a reference model that specifies standards for communications protocols and also the functionalities of each layer.Ī protocol is the set of rules or algorithms which define the way how two entities can communicate across the network and there exists a different protocol defined at each layer of the OSI model.
OSI stands for Open Systems Interconnection. A system that is not connected to the network and can’t be communicated with.Īn interconnection of multiple devices, also known as hosts, that are connected using multiple paths for the purpose of sending/receiving data or media.Ĭomputer networks can also include multiple devices/mediums which help in the communication between two different devices.
