Oh I got this! I'm a professional photographer! The answer is Leaning to se the background before taking the photograph.
Plz mark brainliest! So glad I could help, and Have an AWESOME day!!!
ICF is a type of fusion energy research that attempts to initiate a nuclear fusion reaction by heating and compressing a fuel target. Its normally in the form of a pellet that most often contains a mix of deuterium and tritium.
A nuclear reactor is a device used to initiate and control a sustained nuclear reaction. Nuclear reactors are used at nuclear power plants for electricity generation.
Compare: they are both nuclear, they both produce energy, they both are used at power plants.
Contrast: ICF uses fusion, while a nuclear reactor is used to control a sustained nuclear reaction.
This is all I can help with. By the way, are you in rocket science? 'Cause this stuff is hard.
Answer:
Hash.
Explanation:
An authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification. Smart cards, digital certificates, picture passwords, and biometrics are generally used to perform an authentication in the field of computer.
Hence, when authenticating a user's password, the password supplied by the user is authenticated by comparing the hash of the password with the one stored on the system.
In Computer science, a hash function can be defined as any function which is used to map data by accepting a block of data with variable length size or arbitrary size as input to produce a fixed size hash values or codes.
Generally, when a block of data (input) of arbitrary size is hashed, the resulting hash values or codes is usually smaller than the input data. Thus, hash functions are considered to be a compression of data and as a result, sometimes called compression functions. Basically, the block size of a hash function typically ranges from 128 bits to 512 bits.
