A Level Computer Science Quiz 2018 Part 1

15 Questions

Quiz Description

The question should be, what has computer science and technology not affected in this modern world?. The 21st is what it is today due to the study of computer science and technology. In a way, it may be defined as a branch of engineering science that deals with the study of computer technology, its design principles and applications of the computer systems. It has created so many skills and opportunities for individuals around the world. Some of the skills include programmer, web developers, data scientist.

Based on the Advanced level syllabus, questions have been carefully selected from the topics: “Data structure, Binary operations and logic gates Computer Networking”. These questions sum up together to form a quiz of 15 questions. Each question has four possible answers and only one is correct. For students going in for the CGCE Advanced level examinations, they must keep in mind that questions are neither created nor destroyed but can only be transformed. So, the key to having a good grade is solving and answering past questions and quizzes as much as possible.For more such quizzes click on more or visit our website to gain more materials.
