Computer Science MCQ with detailed explanations for students & freshers preparing for entrance exams, various tests, interviews, competitive exams like GATE exam, interview, competitive examination and entrance exam.
d) All of the mentioned
Here's why all the options contribute to a comprehensive definition of a computer:
a) Computer is a machine or device that can be programmed to perform arithmetical or logic operation sequences automatically: This accurately describes the core functionality of a computer. It can follow a set of instructions (program) to perform calculations and make logical decisions.
b) Computer understands only binary language which is written in the form of 0s & 1s: This is true at the hardware level. Internally, computers operate using a binary system where all data and instructions are represented by combinations of 0s and 1s.
c) Computer is a programmable electronic device that stores, retrieves, and processes data: This highlights several crucial aspects of computers:
Programmable: They can be instructed to perform different tasks based on the software they run.
Electronic: They use electronic circuits and components to process information.
Data storage and retrieval: They can store data (information) for later use and retrieve it when needed.
Data processing: They can manipulate and transform data according to the program's instructions.
Therefore, a complete definition of a computer should encompass all these elements. It's a programmable electronic device that understands binary language, stores and retrieves data, and processes information according to programmed instructions
