Answer:
d. Mainframes came before minicomputers, which led to the development of microcomputers.
Explanation:
The first <em>mainframe</em> was introduced in 1951: The UNIVAC (UNIVersal Automatic Computer I): large computer systems, for general purpose, with hundreds of users (separated from the computer) and fast computations, typically deployed by large business, industry, and government organizations.
The <em>minicomputers</em> are another class of computers that start to evolve since the late of the 1950s and the beginning of 1960s (like LINC, PDP-1, among many others), and focused on to have a more direct contact with the user or programmer, and because of this, it is said that minicomputers were the first 'personal' computers. They were cheaper than mainframes and with less memory capacity.
Finally, the <em>microcomputers</em> appeared around the beginning of 1970s (Micral), and sometime later (Altair 8800, Apple II) and were firstly used by hobbyists and computers enthusiasts. The term microcomputers have been supplanted nowadays by 'personal computers'.

The best security which could be used to ensure integrity and validity of Access database is:
O. database password
Explanation:
Database password is the only option that best guarantee the integrity of an Access database due to the fact that, it limits the number of people who would be able to have access to it. This password is an administrative right given to those who are meant to access it and it is expected to be renewed every few months (probably every 3 months).
<em>Without the password, no other person can be able to login. Also, no two individual can be able to login in same time using same credential login details assigned (that is, in scenario of using the same Username and password)</em>
