Answer:
The answer is "Option c"
Explanation:
In PHP to remove all the session variables, we use the session_destroy() function. It doesn't take any argument is required and then all sessions variables could be destroyed by a single call. If a particular clinical variable is now to be destroyed, the unset() function can be applied to unset a session variable. Its session doesn't unset or unset the session cookie by either of the local variables associated with it.
You could get a laptop for like 200 that could run well and enough space for stuff.

C. to provide online search capabilities
Explanation:
The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.
Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

True, the computer will read from, say, a blu-ray and then transfer it to your RAM to before writing it to your hard drive and then, through the various other wonders of computers, it can be displayed on your monitor.
