Answer:
The correct answer is:
"a laser pointer and a remote control"
Explanation:
Let us look at the options one by one.
notes pages and an LCD projector
When she is using these options, she cannot have the freedom to move as she has to operate the projector somehow.
laptop computer and a pointer
In this case she has to operate laptop so movement will be reduced.
<u>A laser pointer and remote control</u> will give her a lot of freedom to move as she can use the remote control to operate the slides and the pointer to point stuff ont the slides.
Hence,
The correct answer is:
"a laser pointer and a remote control"
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.
