In the machine cycle steps, ________ is the process of carrying out commands.

executing

The ________ is the component of the processor that performs arithmetic, comparison, and other operations.

Arithmetic Logic Unit (ALU)

A byte is uninformative because it provides only enough different combinations of 0s and 1s to represent 8 individual characters.

FALSE

Female connectors have one or more exposed pins, like the end of an electrical cord that is plugged into the wall.

FALSE

For a right-handed user, the left button usually is the secondary mouse button.

FALSE

Information on a display device, sometimes called hard copy, exists electronically and appears for a temporary period.

FALSE

L2 cache is slightly faster than L1 cache but has a much smaller capacity.

FALSE

Most mobile computers and devices separate the display and other components into a different physical case.

FALSE

Saving is the process of copying items from a storage device such as a hard disk to RAM.

FALSE

The amount of RAM necessary in a computer is unrelated to the type of software used.

FALSE

The lower the time in milliseconds it takes to turn a pixel on or off on an LCD monitor, the slower the response time.

FALSE

A system bus allows the processor to communicate with peripherals.

FALSE, expansion

________ is any data and instructions entered into the memory of a computer.

Input

The ________ board is the main circuit board of the system unit.

Motherboard

A(n) ________ printer forms characters and graphics on a piece of paper without actually striking the paper.

Developed by Hewlett-Packard, a leading printer manufacturer, ________ is a standard printer language that supports the fonts and layout used in standard office documents.

PCL

A newer use of OLED technology is in the head-mounted display (HMD), which is a display in a helmet, goggles, or glasses.

TRUE

In addition to games, joysticks, wheels, and gamepads that include force feedback are used in practical applications such as in the military and aviation.

TRUE

Most computers use flash memory to hold their startup instructions because it allows the computer easily to update its contents.

TRUE

RAM technology uses battery power to retain information even when the power to the computer is off.

TRUE

Smart phones use memory cards.

TRUE

Some data projectors are large devices that attach to a ceiling or wall in an auditorium.

TRUE

The more RAM a computer has, the faster the computer will respond.

TRUE

USB 2.0 and USB 3.0 are backward compatible, which means they support older USB devices as well as USB 2.0 and USB 3.0 devices.

TRUE

Until a few years ago, printing a document required connecting a computer to a printer with a ________.

cable

In the machine cycle steps, the term ________ refers to the process of translating instructions into signals the computer can execute.

decoding

Computers process information (output) into data (input).

false Process data into information.

In the machine cycle steps, ________ is the process of obtaining a program instruction or data item from memory.

fetching

Memory ________ on the motherboard hold the memory modules.

slots

The ________ unit is a case that contains electronic components of the computer used to process data.

system

A printer creates images using a laser beam and powdered ink, called ________.
