Answer explanation

The word 'computer' originates from the Latin word 'computare', which means 'to calculate' or 'to count'. This is the correct choice, as the other options incorrectly attribute the origin to Greek, French, or German.

What is a computer also known as due to its ability to perform calculations?

• Computing device

• Calculating machine

• Data processor

• Information handler

Answer explanation

A computer is often referred to as a 'calculating machine' because of its primary function to perform complex calculations quickly and accurately, making this choice the most fitting description.

Which of the following is NOT a basic function of a computer's working system?

• Input

• Processing

• Output

• Networking

Answer explanation

Networking is not a basic function of a computer's working system. The core functions are Input, Processing, and Output, which are essential for data handling and execution.

What does the 'Output' function in a computer's working system do?

• Stores data permanently

• Makes processed data available to the user

• Enters data into the computer

• Converts data into information

Answer explanation

The 'Output' function makes processed data available to the user, allowing them to see results or information generated by the computer. This is essential for user interaction and understanding the results of computations.

What was the primary switching device used in the first generation of computers?

• Transistors

• Integrated Circuits

• Vacuum Tubes

• Microprocessors

Answer explanation

The primary switching device in the first generation of computers was vacuum tubes. They were used to control electrical signals and were essential for early computing before transistors were developed.

Which language was primarily used in the second generation of computers?

• Machine Language

• Assembly Language

• High-Level Languages

• Binary Language

Answer explanation

The second generation of computers primarily used Assembly Language, which is a low-level programming language that provides a symbolic representation of machine code, making it easier to program than pure machine language.

What type of storage device was used in the third generation of computers?

• Optical Disc

• Magnetic Drums

• Magnetic Core

• Winchester Disk

Answer explanation

In the third generation of computers, magnetic core memory was widely used for storage. It provided faster access times and greater reliability compared to earlier technologies like magnetic drums.

Which generation of computers introduced the use of microprocessors?

• First Generation

• Second Generation

• Third Generation

• Fourth Generation

Answer explanation

The fourth generation of computers, introduced in the 1970s, is characterized by the use of microprocessors, which significantly enhanced processing power and efficiency compared to earlier generations.

What is a characteristic of the fifth generation of computers?

• Use of Vacuum Tubes

• Batch Processing

• Artificial Intelligence

• Timesharing System

Answer explanation

The fifth generation of computers is characterized by the use of artificial intelligence, enabling machines to perform tasks that typically require human intelligence, such as learning and problem-solving.

What are micro computers also known as?

• Portable computers

• Mainframe computers

• Super computers

• Mini computers

Answer explanation

Micro computers are commonly referred to as portable computers due to their small size and mobility, distinguishing them from larger systems like mainframe and supercomputers.
