Answer: Strong 128-bit encryption.
Explanation: An individual character corresponds to 8 bits . So if there are 16 characters then,
16
8=128 bits keys
This makes the 128 bit key encryption the strongest amongst all other options.It is strongest because it is almost impossible to decode the 128-character key by any method e.g.-brute-force method.
Other options are incorrect because the characters given by the other bits are as follows: 
=32 characters
=64 characters
=128 characters
Thus, the strongest character key is of 128 bits. for cipher.
Answer:
1. a modem connects a computer to the internet
4. a modem transmits digital signals over a telephone line
5. a dial-up modem communicates using a telephonic call
All of three mentioned above.
Modem stands for modulator de-modulator, and it connects the computer to the internet. Its not the fastest, which is router. And the connection is established via the telephone line, through which the digital signals is being transmitted, And the type used is dial up communication.
Explanation:
The answer is self explanatory.
Explanation:
different computer are connected to a LAN by a cable and an interface card
It is true, Because all the the drives or memories which doesn't have a plates spinning like hard disk are called solid state drives.
