The Samsung Galaxy S9 and S9+ are Android-based smartphones unveiled, manufactured, released and marketed by Samsung Electronics as part of the Samsung Galaxy S series. The devices were revealed at the Mobile World Congress in Barcelona on 25 February 2018, as the successors to the Samsung Galaxy S8 and S8+ .
Samsung Experience (stylized as SΛMSUNG Experience) was the name of the software overlay by Samsung for its Galaxy devices running Android 7.x “Nougat” and Android 8.x “Oreo”. It was introduced in late 2016 on a beta build based on Android 7.0 “Nougat” for the Galaxy S7 , succeeding TouchWiz . [ 1 ]
Odin is a utility software program developed and used by Samsung internally which is used to communicate with Samsung devices in Odin mode (also called download mode) through the Thor (protocol). It can be used to flash a custom recovery firmware image (as opposed to the stock recovery firmware image) to a Samsung Android device.
The output of a cryptographic hash function, also known as a message digest, can provide strong assurances about data integrity, whether changes of the data are accidental (e.g., due to transmission errors) or maliciously introduced. Any modification to the data will likely be detected through a mismatching hash value.
In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates .
The collection of original software media is maintained in order to provide repeatability of the calculated hash values, ensuring admissibility of this data in court. In 2004 the NSRL released a set of hashes for verifying eVoting software, as part of the US Election Assistance Commission 's Electronic Voting Security Strategy.
John Smith and Sandra Dee share the same hash value of 02, causing a hash collision. In computer science, a hash collision or hash clash [1] is when two distinct pieces of data in a hash table share the same hash value. The hash value in this case is derived from a hash function which takes a data input and returns a fixed length of bits. [2]
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]
