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

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

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
