Many protocols use an XOR-based longitudinal redundancy check byte (often called block check character or BCC), including the serial line interface protocol (SLIP, not to be confused with the later and well-known Serial Line Internet Protocol), [8] the IEC 62056-21 standard for electrical-meter reading, smart cards as defined in ISO/IEC 7816, and the ACCESS.bus protocol.
The following definition of the LRC follows from the description above: an [,,]-Locally Recoverable Code (LRC) of length is a code that produces an -symbol codeword from information symbols, and for any symbol of the codeword, there exist at most other symbols such that the value of the symbol can be recovered from them.
One example is the Linux kernel's EDAC subsystem (previously known as Bluesmoke), which collects the data from error-checking-enabled components inside a computer system; besides collecting and reporting back the events related to ECC memory, it also supports other checksumming errors, including those detected on the PCI bus.
In some cases connection of a terminal to multiple hosts is possible via the dial telephone network. Multi-drop is part of the initial Bisync protocol. A master station, normally a computer, can sequentially poll terminals which are attached via analog bridges to the same communication line. This is accomplished by sending a message consisting ...
In computer networking, linear network coding is a program in which intermediate nodes transmit data from source nodes to sink nodes by means of linear combinations. Linear network coding may be used to improve a network's throughput, efficiency, and scalability , as well as reducing attacks and eavesdropping.
(Reuters) -U.S. President Donald Trump on Tuesday pardoned Silk Road founder Ross Ulbricht, who was sentenced to life in prison for running an underground online marketplace where drug dealers and ...
Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
With 30 miles (48 km) of tall black temporary fencing, 25,000 law enforcement officers and security checkpoints set up to process hundreds of thousands of spectators, Washington is braced for ...
