An app launcher replaces the stock user interface for organizing the home screen and app icons predominantly in the Android world; however, they are also available for jailbroken iPhones (see iPhone jailbreaking and Cydia). See Launchpad.
This delay in routers is what we called Packetization delay
or also called Accumulation delay. Packetization delay is the time required for
the information to pass on the wires. The data rate of the links that passes
thru the wires cause the delay.
Explanation:
Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database.And The ACID properties, in totality, provide a mechanism to ensure correctness and consistency of a database in a way such that each transaction is a group of operations that acts a single unit, produces consistent results, acts in isolation from other operations and updates that it makes are durably stored.
Answer:
Explanation:
Network Access Control is needed to make sure that only set of verified users access the network.
It makes sure that the users are authenticated and only set of some verified users have access to network.
Set of NAC solutions like Impulse SafeConnect, Extreme Networks, ExtremeControl, Auconet BICS, ForeScout CounterACT, Pulse Policy Secure could be installed in the system which along with basic profiling will make sure authenticated access to the network.
Other than this basic encryption-decryption algorithm can be used in this regard. Network components could use encryption algorithms like RSA and DES. These algorithms will make sure that the information from database side is well encrypted. Once that information goes to the network component. They can decrypt the encryption by generating relevant key using the same algorithm.
This will only allow authentic users to access information and also it will stop the leakage of information in between the transmission because of encryption.
