(vältida levimist) Veast taastumine on protsess, mille käigus Veakindluse saavutamine süsteem püüab jääda tööle või taastada oma töövõime läbi rekonfiguratsiooni (isegi, kui rike on süsteemis alles). Näited: vigade maskeerimine, kordamine, tagasipöördumine jne... Bit-flipid seoses kosmilise kiirgusega: A person on an airplane over the Atlantic at 35,000 ft working on a laptop with 256 Mbytes (2 Gbits) of memory. At this altitude, the soft error rate (SER) of 600 FITs per megabit becomes 100,000 FITs per megabit, resulting in a potential error every five hours. Vigade näited 1 FIT (failures in time), is the number of failures in 1 billion device-operation hours. A measurement of 1000 FITs corresponds to a MTTF (mean time to failure) of approximately 114 years. Püsivad: viga on stabiilne ja alaline Vigane komponent tuleb asendada Klassikaline näide: stuck-at vead Perioodilised rikked (intermittent) Esinevad ajutiselt, seoses süsteemi või selle komponentide
From this data, the device driver constructs a frame, with appropriate Ethernet header information and a frame check sequence at the end. The circuitry on the adapter card then takes the frame and converts it into an electrical signal. The voltage transitions in the transmitted bit stream are in accordance to the format called Manchester Signal Encoding. Manchester encoding describes how a binary ONE and ZERO are to be represented electrically. Manchester encoding is used in all 10 Megabit per second Ethernets; for example, 10BASE2 Thin Ethernet, 10BASE5 Thick Ethernet, and 10BASE-T Twisted-Pair Ethernet. You may want to read the additional perspective on Manchester encoding. In the 100 Mbps Ethernet section of the Compendium there is a section describing the different Fast Ethernet encoding schemes. Here, we see an example of the signal transitions used to encode the hexadecimal value "0E", which converts to "00001110" in binary
