CHIP

RAM or Memory

digital cameras most often use __ for storage

SD cards or flash memory

A ____ is an optical code that represents data with bars of varying widths or heights.

barcode

the numbering system we commonly used is called the decimal numbering system because it uses —- symbols to represent all possible numbers

base 10

a __ is the smallest unit of data a binary computer can recognize

bit

8 bits grouped together as a unit form this

bite

T/F as a hard drive begins to get full, it takes less time to locate the data stored on a hard drive

false

____ are small components typically made out of aluminum with fins that help to dissipate heat.

heat sinks they have fan and blow on fins of aluminum to dissipate heat

Print speed is typically measured in ____.

pages per minute (ppm)

With bitmapped images, the color of each ____ is represented by bits; the more bits used, the better the image quality.

pixel

a __ is the smallest colors le area on a video display device

pixel (picture element)

memory that loses its contents when power is removed is

volatile

Notebook and netbook computers usually have a keyboard that is similar to a desktop keyboard, but it is typically smaller.

True

adding RAM to a computer is something most users can do themselves

true

the binary numbering system only uses two symbols — 0 & 1

true

to create 3d ram or flash memory chips the memory cells are stacked on top to create layers

true

display device size is measured diagonally from core net to corner as opposed to the way TV screens are measured

FALSE — TV is diagonal, monitors are perimeter

Printers produce soft copy

FALSE — hard copy is tangible, soft copy can't hold it's like monitor

Images need to be scanned at a lower resolution if the image will be enlarged significantly.

FALSE — it gets pixelated

today's CPU contain hundreds of millions of transistors and the number doubles approximately every 18 months, a phenomenon known as Caboni's Law

FALSE — it's Moore's law, the power of minitursuxstiin doubles every two years. named after gordon moore who helped find the company INTEL

Joysticks are headphones with a built in microphone

FALSE — joystick is an analoug input

Storage media are volatile.

FALSE — storage media is like hard drive, volatile is if it's lost

to add RAM you typically install 8 individual chips

FALSE — they aren't chips with the pins, now it's a card that goes in (a sim)

anything stored on a storage medium is referred to as a

FILE

RAM shed to sets of chips now it's

SIMS or memory modules

SSD are not subject to mechanical failures like magnetic hard drives and are more resistant to shock and vibration

TRUE

Since retrieving data from memory is much faster than from the hard drive, disk caching can speed up performance.

TRUE (disk caching is puts things you commonly access in memory)

when comparing the zoom capabilities of a digital camera look for optical zoom not digital zoom specifications

TRUE optical zoom is what the lense does — digital is what the computer can blow it up

RAM can be thought of the workspace for the computer

TRUE — it's your desk at the office

SSD are becoming the norm for netbooks, mobile devices, and portable devices

TRUE — no mechanical hard drive it's SSD

To connect multiple USB devices to a single USB port, a ____ can be used.

USB hub or dongle

adding RAM to a PC will typically improve performance

correct

A(n) ____ uses a printhead consisting of pins that strike an inked ribbon to transfer the ink to the paper.

dot-matrix printer (pins are the dots) used for duplicates like carbon copies

T/F single core CPU allow computers to work on more than one task at a time

false single core is one thing at a time

The process of representing data in a form that can be understood by a digital computer is called decimal byte representation.

false — it's binary byte representation

RAM is connected to the CPU through the Backside Bus

false — it's connected through a MEMORY bus

____ consists of nonvolatile memory chips that can be used for storage by the computer or the user.

gigabytes (memory) STORAGE is terabyte

A(n) ____ is a flat, touch-sensitive device used in conjunction with a digital pen.

graphics tablet

___ and or names are typically assigned to each storage device

a __ typically rests on the desk or other flat surface and is controlled by users hand

mouse

most computers support the __ standard which means the computer automatically configured new devices as soon as they are installed and the computer is powered up
