Chapter 1 Test Review

When was the first computer invented?

• The 1940s

• The 1960s

• The 1980s

• The 1990s

Which of the following describes an important advantage the ENIAC had over earlier computing devices?

• It was smaller and generated less heat

• It could be re-programmed by the machine operator

• It used transistors instead of vacuum tubes

• It had multiple CPUs

What concept describes the idea of storing computer programs in memory?

• Integrated circuit

• Vacuum sealed

• Moore's Law

• von Neumann architecture

Which of the following was a job for the ENIAC computer?

• Calculate artillery firing tables

• Make atomic energy calculations

• Predict the weather

• All of these

The first computers used _________________ to create electronic signals.

• vacuum tubes

• transistors

• semiconductors

• batteries

According to Moore's Law, what happens about every two years?

• The heat generated by the same size of integrated circuit doubles

• Microprocessors can do the same work with half as many transistors

• The number of transistors we can cheaply place in the same physical area doubles

• Computer programs will get twice as complicated

Moore's Law can be used to predict computer power in the near future.

• True

• False

Which of the following describes the external shell that holds most other computer components inside?

• Motherboard

• Computer case

• CPU

• Removable storage media

CD-ROMS, compact flash drives, and USB memory sticks are all examples of what kind of component?

• Peripheral

• Hard drive

• Removable storage media

• CPU

Why might you want to install a separate video card into your system?

• Because you wouldn't see anything at all otherwise

• Because it's cheaper than the built-in video card component on your motherboard

• Because video cards can give you advanced sound features also

• To get higher quality and higher performance in your graphical output
