Solid state storage
also called flash memory storage provides fairly fast access to data.
OLEDs
have a faster response rate than standard LCD screens.
REFRESH RATE
As applied to monitors, the number of times in one second an electronic beam can fill the screen with lines from top to bottom. Also called vertical scan rate.
refresh rate
In CRT monitors an electron beam is focused onto individual phosphors to make them glow and produce an image. The gun has to be scanned over the phosphors starting at the top and working to the bottom of the monitor. The number of times the electron beam does this each second is known as the refresh rate.
Gaming
Type of computers that typically include: state-of-the-art sound capabilities, lots of memory, very fast processors.
Random access
is the ability of a device to “jump” directly to the requested data.
Power surge
is a sudden increase or spike in electrical energy, affecting the current that flows to electrical outlets.
Duty cycle
A printer’s ____ determines how many pages a printer is able to churn out.
Duplex
A ____ printer can print on both sides of the paper.
pcl
A standard printer language that supports the fonts and layout used in standard office documents. (is the most widely used language for communication between computers and printers.)
Lojack for laptops
example of a tracking and recovery software
Notebook
is also referred to as a laptop computer.
Tower units
are the form factor of choice for computer owners who might want to upgrade components in the future because it is easy to get inside the case and swap out parts.
Word size
refers to the number of bits that a microprocessor can manipulate at one time.
system unit
is the case that holds the main circuit boards, microprocessor, memory, power supply, and storage devices of a personal computer system.

INK JET PRINTER
a type of nonimpact printer that forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper
LASER PRINTER
Type of high-speed, high-quality nonimpact printer that creates images using a laser beam and powdered ink, called toner. The laser beam produces an image on a special drum inside the printer. The light of the laser alters the electrical charge on the drum wherever it hits, causing toner to stick to the drum. The toner then is transferred to paper through a combination of pressure and heat
DOT MATRIX PRINTERS
Made to print a large number of pages fairly quickly, transfers ink by striking a ribbon with pins.
