A Level Computer Science Quiz 2016 Part 1

15 Questions

Quiz Description

Computer science encompasses a very wide range of fields, and new ones continue to emerge as time goes by and new technologies are invented. Most computer scientists mainly deal with the theory, design, development, and application of software and software systems, as opposed to hardware. With its very vast field with many different areas, specializations, and applications, basically computer science is the study of all the different components of computers and computer systems.

The knowledge of computers is very complex at times to understand to the fullest. In a way to guarantee the success of students facing/going in any for any examinations (most especially CGCE), a set of questions based on the topics “computer components, Data structures and algorithm, programming have been systemised for each individual to test his/her knowledge.

With a total of 15 questions, this quiz will help each student examine how prepared they are for any computer science exams.For more inquiry about other materials, you can visit our website.
