Preliminary Exam ITC 1O1L

Which of the following best defines a computer?

• A machine that processes data into information

• A device that only stores data permanently

• A system that can only execute pre-defined instructions

• An electronic device that can perform calculations

The UNIVAC, one of the first commercially available computers, was primarily used for:

• Military applications

• Business and administrative data processing

• Scientific calculations

• Graphic design

How does the CPU interact with input and output devices during data processing?

• It directly manages all storage devices.

• It receives input, processes it, and sends output to display devices.

• It acts as a power source for input devices only.

• It performs calculations without needing input or output devices.

What is the primary role of the CPU in a computer system?

• To execute instructions and process data

• To store data permanently

• To provide visual output

• To manage input devices

Charles Babbage is referred to as the father of the computer primarily because:

• He developed the first software program.

• He conceptualized a programmable computing machine.

• He created the first electronic device.

• To manage input devicesHe established the first computer network.

The abacus, an early calculating device, is believed to have been first used in:

• 500 BC, for storing trade records

• 2,400 BC, for performing basic arithmetic operations

• 1837, for computing logarithmic functions

• 1936, for algorithm development

Alan Turing is known for which of the following contributions?

• Developing the first graphical user interface

• Proposing the concept of a universal machine for computation

• Creating the first personal computer

• Inventing the first computer virus

Which sequence accurately describes the flow of data in a computer system?

• Input → Storage → Processing → Output

• Input → Processing → Output → Storage

• Processing → Output → Input → Storage

• • Output → Input → Storage → Processing

Which of the following devices is primarily used for inputting data into a computer?

• Monitor

• Scanner

• Projector

• Speakers

How do the primary components of a computer work together to process data?

• The CPU retrieves data from storage and sends it directly to output devices.

• RAM temporarily holds data while the CPU processes it, and input devices provide the data.

• The motherboard stores input data and the power supply handles processing.

• Output devices process incoming data and send it back to the CPU for storage.
