Answer:
ring network
Explanation:
In a ring network, the nodes are arranged in a circular pattern where each node is connected to two adjacent nodes. In this topology, any node can communicate with any other node via the intermediaries.
In comparison,
- in a star network every communication needs to pass through a central hub node
- in a bus, each node is connected to a shared linear communication bus.
- in a hierarchical network nodes are organized along a tree structure layout.
Answer:
The Difference is because of the salt added to the password before hashing or encrypting it.
Explanation:
The Difference is because of the salt added to the password before hashing or encrypting it.
Salts are random data used to mention uniqueness. Suppose if two users have same password for the same system. By adding Salt to the password makes it unique in the crypto system. Its a added security layer which can safeguard the passwords or hashed data in the keystore or storage.
Salt can be prepended to the password or appended to the password.
Suppose the password is “stuti” then its SHA256 HASH value is <u><em>“4beb1eb6f438495eede7b14ac0d2b955636a49412cd4eb5714341f5716144954”</em></u>
So, if we add a salt with random string <em>brainlysalttest</em> then its SHA256 HASH value is <u><em>“5429e85778f1b9f493da637848f253dedf3edbfbb72782d43eb7337cee45ab0c”</em></u>
If we append the salt <em>brainlytestsalt</em> to the same password and hash it using SHA256 then its hash value is : <u><em>“3919b677d80ae0da2b58f70b464f6492670ccffee78cf52972c6983995ed8f52”</em></u>
So clearly Salting to the password and Hashing the salted password will make the difference and also unique.
Answer: The .(dot) character
Explanation: in Linux, the period (dot) is short hand for the bash built in source. It will read and execute commands from a file in the current environment and return the exit status of the last command executed.
The .(dot) character is the first character for a file or directory names if they should not be displayed by commands such as ls unless specifically requested
