Sedaia [141]

Answer:

Recently, with the new and advanced hacking algorithms and affordable high-performance computers available to adversaries, the 36 character computer suggested passwords can easily be insecure.

Explanation:

The 8 length passwords generated pseudo-randomly by computers are not secure as there are new algorithms like the brute force algorithm that can dynamically obtain the passwords by looping through the password length and comparing all 36 characters to get the right one.

And also, the use of high-performance computers makes these algorithms effective

Scrat [10]

Technician A is correct.

Electrochemical batteries can be classified into two main categories; Primary Cells and Secondary Cells.

A primary battery or cell cannot easily be recharged after use and is usually recommended to be discarded following discharge. Most primary cells are termed dry due to their capability of utilizing electrolytes contained within absorbent material.

A secondary cell, on the other hand, can be recharged electrically to their original pre-discharge condition.
