This document contains two practice tests for an Introduction to IT course. Test A contains three questions - the first asks to draw and explain the block diagram of a computer (10 marks), the second asks to list 5 DOS commands with syntax and examples (5 marks), and the third asks two decimal to binary conversions (5 marks total). Test B follows the same format but contains different questions - describing computer generations (10 marks), listing 5 input devices (5 marks), and performing one decimal to octal and one hexadecimal to binary conversion (5 marks total). Both tests are worth a maximum of 20 marks and are to be completed in 1 hour.
