What is the sequence in which a computer operates?

• Input, output, process

• Input, process, output

• Process, input, output

• Output, process, input

Answer explanation

A computer operates in the sequence of Input, Process, Output. First, it receives data (input), then it processes that data, and finally, it produces results (output). Thus, the correct answer is Input, process, output.

Which is the first general-purpose programmable electronic computer?

• ENIAC

• EDVAC

• EDSAC

• UNIVAC

Answer explanation

ENIAC, completed in 1945, is recognized as the first general-purpose programmable electronic computer, capable of performing a variety of calculations, unlike its successors which were more specialized.

What type of device is a computer?

• Electrical device

• Electronic device

• Electro magnetic

• Electro mechanical

Answer explanation

A computer is classified as an electronic device because it processes data using electronic circuits and components, distinguishing it from electrical, electromagnetic, or electromechanical devices.

Who is considered as father of computer?

• Charles Babbage

• John Lickert

• John Mauchly

• M.V Wilkes

Answer explanation

Charles Babbage is known as the father of the computer for his design of the Analytical Engine, a mechanical general-purpose computer, which laid the groundwork for modern computing.

Who invented Analytical engine?

• Charles Babbage

• John Lickert

• John Mauchly

• M.V Wilkes

Answer explanation

The Analytical Engine, considered the first mechanical computer, was invented by Charles Babbage in the 1830s. His design laid the groundwork for modern computing, making him a pivotal figure in computer science.

What is the main electronic component of the first generation computer?

• Integrated circuit

• Microprocessor

• Transistors

• Vacuum tubes

Answer explanation

The main electronic component of the first generation computer was vacuum tubes. They were used for switching and amplification before transistors and integrated circuits were developed.

How does the parallel port transfer a byte?

• Bit by bit

• 2 bits at a time

• 4 bits at a time

• 8 bits at a time

Answer explanation

The parallel port transfers data 8 bits at a time, allowing a full byte to be sent simultaneously. This is more efficient than transferring bit by bit or in smaller groups, making it suitable for faster data communication.

Which is an internal power supply units of CPU?

• CVT

• UPS

• SMPS

• Stabilizer

Answer explanation

The correct answer is SMPS (Switched-Mode Power Supply), which is an internal power supply unit that converts electrical power efficiently for the CPU and other components. CVT, UPS, and Stabilizer serve different purposes.

What is the purpose of expansion slot in mother board?

• To insert the RAM

• To insert the mouse

• To insert the keyboard

• To insert the additional peripherals

Answer explanation

The expansion slot on a motherboard is designed to insert additional peripherals, such as graphics cards, sound cards, or network cards, enhancing the system's capabilities. It does not serve for RAM, mouse, or keyboard connections.

What is the purpose of memory unit in a computer?

• Accepts data

• Displays data

• Process data

• Stores data

Answer explanation
