Introduction to Computers Quiz

What is a computer?

• A device that displays output and processes data given to it.

• An electronic device that accepts user input (data) and processes it under the influence of a set of instructions referred to as programs to produce desired output (information).

• A device that uses instructions (programs) to accept and process data given to it in a variety of forms in order to produce useful information.

• A device that accepts user input (data) and transforms it under the influence of sets of special instructions called programs to produce information.

What are the physical parts of a computer?

• Hard drive, RAM, and power supply

• Monitor, keyboard, and mouse

• CPU, motherboard, and main memory

• System unit, peripheral devices, and input devices

What are the characteristics of first generation computers?

• The circuit technology used was large scale integrated (LSI) and very large scale integrated (VLSI) circuits

• Used integrated circuits (ICs) in their processors and semiconductor memories or magnetic disks for storage

• Used transistors for processor technology and magnetic cores for memory technology

• Large in physical size, relied on thermionic valves (vacuum tubes) to process data and magnetic drum memory for data storage
