In computer networking, localhost is a hostname that refers to the current computer used to access it. The name localhost is reserved for loopback purposes. [1] It is used to access the network services that are running on the host via the loopback network interface.
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
For example, in modern systems, this work is dominated by the round-trip through the IO bus to the network interface. The standard has been revised since the initial release to make it more suited for modern high performance, massively parallel computers. [3] The MPI library was ported from the retronymed Portals 2 to the new Portals 3.0. [4]
Loopback (also written loop-back) is the routing of electronic signals or digital data streams back to their source without intentional processing or modification.It is primarily a means of testing the communications infrastructure.
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally wired Ethernet. [1]
A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [2] (routable only within the scope of private networks, but not the global IPv6 Internet). Because they are not globally reachable, ULAs are somewhat analogous to IPv4 private network ...
In Solaris/OpenSolaris, the loop device is called "loopback file interface" or lofi, [2] and located at /dev/lofi/1, etc. SunOS has the configuration program lofiadm. lofi supports read-only compression and read-write encryption. Available is also a 3rd-party driver fbk (File emulates Blockdevice), for SunOS/Solaris since summer 1988. [3]
In object-oriented programming, an interface or protocol type [a] is a data type that acts as an abstraction of a class. It describes a set of method signatures , the implementations of which may be provided by multiple classes that are otherwise not necessarily related to each other. [ 1 ]
