Which of the following is the correct definition of Computer?
That's right! The correct definition of computer is:
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
