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.
Where a system (such as a modem) involves round-trip analog-to-digital processing, a distinction is made between analog loopback, where the analog signal is looped back directly, and digital loopback, where the signal is processed in the digital domain before being re-converted to an analog signal and returned to the source.
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.
Convert the interface of a class into another interface clients expect. An adapter lets classes work together that could not otherwise because of incompatible interfaces. The enterprise integration pattern equivalent is the translator. Yes Yes Yes Bridge: Decouple an abstraction from its implementation allowing the two to vary independently ...
The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
EtherType is a two-octet field in an Ethernet frame.It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed.
An interface cannot. A class or abstract class can only inherit from one class or abstract class. A class or abstract class may implement one or more interfaces. An interface can only extend other interfaces. An abstract class may have non-public methods and properties (also abstract ones). An interface can only have public members.
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]
