Blue tooth devices must be within ______________ of each other

30 feet

The technology that deposits ink on paper is the foundation for

3D printers that deposit layers of plastic, resin or metal that build into three-dimensional objects.

Peak data transmission rate of Bluetooth is________________ suitable for sending small bursts of data rather than large files.

3Mbps

Filaments cost about 10 dollars a pound and the acronyms are:

PLA, ABS, PC

Which of the following are not considered peripheral devices?

RAM and CPU

The utopian vision for the internet of things (IoT)

is a busy hive of smart sensor that work behind the scenes

Polylactic acid (PLA)

is a versatile and biodegradable filament because it is made from corn starch

Polycarbonate (PC) filament

is even sturdier and is used primarily for items that will be used in high impact situation

Acrylonitrile butadiene styrene (ABS) filament

is more durable and heat resistant making it suitable for printing objects that need to withstand some wear and tear

Filament deposit modeling (FDM)

melts a coiled filament and deposits it in layers that harden and form an object

Touchscreens can display

menus, scroll bars, and other controls and virtual keyboards.

It is unnecessary to turn devices off before disconnecting them, some devices should.

not be disconnected while in the middle of data transfers

The basic IoT circuit board contains

one or more sensors, a power source, a transmitter and an antenna.

Basic laser printer produces

only black and white printouts

An important industrial use for 3D printers

prototyping new products such as automobile headlights, smartphone cases, firearms and full scale bicycles

a Magnetometer can

provide data about the direction of travel for vehicles and handheld devices

The two most common technologies used for touchscreen displays are

resistive and capacitive

Accelerometer sensor can

sense if a laptop computer is dropped or a vehicle brakes sudently

the part of the data bus that stretches from RAM to various expansion ports is called___________ this part of the bus has several branches to accommodate data traveling to and from various ports.

the expansion bus

The part of the data bus that runs between the microprocessor and RAN is called-_____________Is the fastest part of the data bus.

the local bus or internal bus.

Color laser printers are available but

they are more costly than basic black and white models

Because the human body is an electrical conductor the

touch screen produces a change in electrical current

If you want to connect more devices than the available number of USB ports you can

use a USB hub

Bluetooth device options include

wireless keyboards, mice, Nintendo and Wii game controllers

Before unplugging a device such as a USB flash drive

your computer might require notification

Sensors include

GPS, Motion, Light, Water, Contact, Accelerometer,, Temperature

a __________________handles image data, freeing the CPU for other processing tasks

GPU

Which printer is slower but less expensive to operate?

Ink jet printer

How does data flow from an external storage device to the processor?

Data begins on the internal bus and then ends up on the local bus.

The...............bus carries data from an external device to RAM

Expansion

The most commonly used general purpose technology for connecting gadgets to laptop and desktop computer is

USB port

A 3D printed object is based on

a 3D model that is essentially a 3D vector graphic

a 3D model can be derived from

a 3D scan of a real object or created using graphic software

A graphic card contains

a graphics processing unit (GPU)

Also used to operate a touch screen

a special capacitive stylus or touchscreen gloves

Additive manufacturing is used to produce

hearing aids and medical devices that are custom fit or unique.

gyro sensor can

help a drone remain level in the air, help a VR headset track head movements

is a slow wireless technology used to connect devices within a radius of about 30 feet

bluetooth

Touch screen use_______________ _technology

capacitive

Dental labs use 3D printing to produce

crowns, bridges and dental appliances.

Display devices require ______________________to generate and transport the signals for displaying an image on the screen

graphics circuitry
