Computer organization

The questions from computer organization usually test the basic knowledge that one acquires at the beginning of computer learning. It also tests the knowledge of candidates on various computer parts and their functioning. The computer system is formed when 2-3 parts combine and perform individually as well as coherently.

You will have various sets of questions in this article which can help you ease the pressure for this section. You can also practice the questions at the end. The computer consists of many different parts of input units, output units, memory units, etc. And we will discuss with you in detail about each of these parts.

Output units

Output units allow the computers to send the data to other users. Usually, a display device is considered as the output unit because it displays the texts, graphics, and other information. The common examples of output units are speakers, monitors, printers, etc.
