chapter 9: Principles of Computer Operations: Following Instructions

question

Computers only execute instructions; therefore, rerunning a program with the same data produces exactly the same result every time.
answer

True
question

Computer memory is divided into bytes of 9 bits.
answer

False
question

Every memory location in the computer is numbered, starting at 0.
answer

True
question

Each byte in memory is limited in size.
answer

True
question

A megabyte is exactly one million bytes.
answer

False
question

The ADD instruction adds the values, not the address numbers of the memory locations.
answer

True
question

The ability to store different values in its memory locations makes the computer a flexible tool.
answer

True
question

A single device driver will generally work with several different peripheral devices.
answer

False
question

Due to its simplistic design, Microsoft’s Vista operating system reportedly contained fewer than 4,000 lines of program code when it was released in 2007.
answer

False
question

Starting a computer is called booting.
answer

True
question

Android, an open source OS, and Apple’s iOS are examples of operating systems for mobile devices.
answer

True
question

Miniaturization is the biggest achievement of microchip technology.
answer

False
question

A passage is the path in a semiconductor where electricity travels.
answer

False
question

A field effect transistor is a connector between two wires that can be controlled to allow a charge to flow between the wires (conduct) or not.
answer

True
question

The fear of computers taking over the world has died down since the 1950s and 1960s.
answer

True
