"We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress." -- J.

Controller Area Network (CAN Bus) - Error Detection And Fault Confinement
Fault Confinement guarantees proper network functionality and a continued availability of the data transportation system by adjusting the behavior of defective nodes, even up to a point where a node may remove itself from the network (self-retirement).

Watsapp is working on detecting suspicious links shared via its platform...
Watsapp is testing a new feature to notify users of suspicious/malicious messages. At the moment the feature is being tested on Watsapp beta version for android users only. This upcoming features tags suspicious links shared within its platform.
A featured was previously launched by Watsapp to control spread of fake messages, which prevented spamming of forwarded messages by limiting forwarding of messages to only 5 recipients.
Currently the feature is available for android users only but according to some sources iPhone and Windows users will also be able to take advantage of it in future updates.
This feature of detecting dubious links works, as soon as someone forwards any suspicious link to a recipient. A red label will be shown on the message telling the recipient to beware of this link.
As per the sources, the feature uses an algorithm to detect errors in the link and if it detects any anomaly, the link is marked suspicious.
If the user still tries to open the link, they are redirected to a new window where they are again informed of the suspicious nature of the link. Link is checked locally on receivers device.
Watsapp messages are end to end encrypted, which means that Watsapp cant check the messages and links on its server that is why the link is checked locally on receivers device.
If you want to activate this feature, which is only available in Watsapp beta version, Android users will have to update the app to version 2.18.221 or later. Still if you are unable to the feature then, reinstall Watsapp but first backup the chat history.

Parity Memory / non-parity Memory and ECC Memory
New Post has been published on https://www.tuthowto.com/parity-non-parity-memory-ecc-memory/
Parity Memory / non-parity Memory and ECC Memory
Parity Memory / non-parity Memory and ECC Memory:
Memory modules have historically been on the market in 2 basic flavors: non-parity and parity Memory. (Actually, some sizes and designs are in the market in non-parity. However, most are available either way.) Non-parity is “regular” memory–it contains specifically one little bit of memory for every information to be stored.
eight bits are using to store every byte of data. Parity memory adds an additional single bit for each eight bits of data, used just for error detection and correction. nine bits of data are used to store every byte. The table below shows a outline of the various common module sizes and their bit widths:
Module Type
Bit Width of Non-Parity SIMM
Bit Width of Parity SIMM
30-Pin SIMM
8 Bits
9 Bits
72-Pin SIMM
32 Bits
36 Bits
168-Pin DIMM
64 Bits
72 Bits
Parity Memory / Non Parity Memory:
Parity memory is often using for parity checking, an essential error detection, on PCs. It may also be used for a complicated sort of error detection and correction known as ECC.
Non-parity memory provides no error detection capabilities in many aspects
unless these are providing through external circuitry (which is mostly is not doing on regular PCs.)
In recent years, a brand new kind of memory has become famous: ECC memory. As the name implies, this type of memory specifically designed to permit the use of ECC on latest systems that have chipsets to support it. Also, parity memory will run on some systems.
Because of both kinds of memory support ECC, there has been most significant confusion regarding the distinction between ECC and parity memory, mainly since they typically are the quote with similar specifications.
Difference Between Parity Memory / Non Parity Memory:
The biggest distinction between 2 kinds of memory is that, ECC memory works in ECC mode and then does parity , however ECC memory doesn’t add plain parity checking mode. The explanation is that while an ECC module contains one additional bit per byte, the way parity also ones do. the additional bits can’t be separately accessed, which is needed for parity operation, to create matters more confusing, some systems cannot use the ECC modules in any aspects, because they’re wired differently than parity modules. Lets take a look below colums:
Module Type

Caution:
Most ECC and parity modules have an identical identity and bit widths, which suggests that a 4×72-60 DIMM might be either an ECC module or a parity module, how it is manufacturing. Ensure you discover out precisely what is that you are buying and what your system supports.
ECC-only modules are sometimes tagged “ECC.” Some systems can work fine with them; however, others won’t.Parity memory was once the only kind sold; it’s currently selling a lot of less often than non-parity memory, particularly the quicker and newer types of memory. It is usually due to the de-emphasis on error detection in more modern systems and therefore the number of standard chipsets that do not support parity checking.
Parity memory uses 12.5% additional DRAM memory than non-parity (1 bit further for each 8) which makes it more expensive. However, the main reason is its prices. Also, it’s producing in much smaller quantities nowadays.
Summary:
Parity memory stores a parity bit for each byte or other unity of memory. A parity bit is enough to notice some (not all errors) however doesn’t facilitate in correcting those mistakes. Some CPUs will mix parity bits into an Error Correcting Code (ECC) that fixes some errors.
If you wish eight memory chips to create an 8-bit non-parity SIMM, you need nine memory chips to form AN 8-bit parity SIMM. The parity SIMMS are more expensive, both as they need an additional chip, and they’re creating it in lower quantity.
Parity indicates whether or not the quantity of 1’s within the byte was even or odd, the last time it had been stored. Every time Parity calculates whenever the byte is scan. The check bit may be one or zero. If the parity bit we estimate on reading doesn’t match the parity bit keep with the byte, there has been a computer error. Parity memory will discover this but non-parity memory can’t.
