Answer:
There are hybrid system that consist of WiFi, GPS, GSM and IP address to locate the mobile devices.
Explanation:
In Cellular phone communication, hybrid technique is used to locate to find the locations. It consist of WiFi, GSM, GPS and IP addresses. GPS technology is used with satellite communication. Location has been sent from satellite to the mobile network with the help of Google maps. There are few other techniques used to such as GSM based techniques that is used by the help of radio signals strength to find the location of the device. This technique is helpful in the areas where the many communication tower are there to locate the signal strength in the area of the mobile device. WiFi also used to locate the mobile device with the help of IP addresses.
In mobile phones, different combinations of all above technologies used to provide the network connectivity such as WiFi and GPS locator in the mobile Phone. This is called Cellular locating technology.

Answer: Explanation:
Salting alters the hash of a password so that it does not physically match the hash of another password. A salt and password are concatenated and processed with a cryptographic hash function. Salt prevents use of rainbow and hash tables to attacking and cracking passwords.
For example, a user has the password, "password000" and is put through a SHA1 hash. In the password database, all of the users with the password "password000" will have the exact same hash, because of the nature of hashing functions. So, if an attacker breaches the database and brute force the password of the user mentioned above, he could look for all the hashes that match the original user's and would know their passwords are also "password000".
By applying a salt, the password hashes would no longer be identical to one another, even though the actual password is still the same. This requires the attacker to go in and attempt to brute force the second password (which has a different salt), even though it may be the same as the first.
In conclusion, it prevents an attacker from uncovering one password and subsequently uncovering multiple others.
