Answer:
computer means an electronic machine which process raw data and gives meaningful information to the user
Answer:
The metric column basically indicate the cost of the route in the routing table and also decide correct route in the routing table.
In the routing table, the lowest metric route is more preferable route as compared to others. In the networking, the routing table is basically used to store the data or information in the form of table in the router.
In the computer network, the routes are listed for the particular destination in which the routes are basically associate that particular routes.
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.
Answer: Static local variable is a variable that is initialized as static only one time inside a function and whenever it is called in that function it will be accessible.
Explanation: Static local variables are very useful variables which are declared as static in a particular function. Static local variable is initialized only one time in a function and whenever the function in which it has been declared ,the value of the variable will be accessible by as many times it has been called in the function in which it is declared.
