Cloud storage is a service model in which data is maintained, managed, backed up remotely and made available to users over a network (typically the Internet).
Answer:
The matrix theory is used by hill cipher.
Explanation:
Th technique which uses matrix theory is hill cipher technique.
Hill cipher technique is a polygraphic substitution cipher and it is based on linear algebra.
For encrypting a message in Hill Cipher technique each block of n letters is multiplied by an invertible matrix of nxn and that to against modulus 26 and for the decryption of the message, every block is multiplied by the inverse of the matrix that was used for encryption.
Answer:
Star Topology
Explanation:
Star network topologies are common in home networks, where the central connection point may be a router, switch, or network hub. Unshielded Twisted Pair (UTP) Ethernet cabling is typically used to connect devices to the hub, though coaxial cable or optical fiber may also be employed.
Answer:
5
Explanation:
The operator 'x++' is called the post increment operator, it is assign first and then increment.
The operator '++x' is called the pre increment operator, it is increment first and then increment.
So, both are increment operator which increment the value by one.
initially the value of x is zero,
++x increase the value to 1 and than assign to x.
then, x++ it assign to x first then increment by 1 means x=2
and so on.....
Their are five increment operator are used. so, the result is 5.
