Answer:

a. True

Explanation:

A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user. Computers can be classified on the basis of their size and capacity as follows;

I. Supercomputers.

II. Mainframe computers.

III. Mini computers.

IV. Micro computers.

Mainframe computers were developed and introduced in the early 1950s.

Mainframe computers are specifically designed to be used for performing multi-programming because they are high-performance computers with the ability to handle multiple users. As a result, it simply means that mainframe computers can be used to effectively and efficiently perform the work of over one hundred (100) users at a time on the computer. Some examples of mainframe computers include the following; IBM Es000 series, CDC 6600 and ICL39 Series.

Furthermore, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.
