Supporting Mobile Digital Devices Flashcards
Accelerometer
Mobile technology that can determine the orientation of a device with a sensor that measures the acceleration of the device direction.
Backlight
The typical form of illumination used in a full-sized LCD display.
Baseband
A transmission scheme where a single signal sends data using the entire bandwidth of the transmission media. Compare with broadband.
Baseband RTOS (Baseband Real Time Operating System)
In a mobile device, memory that contains an operating system that is separate from the end-user operating system (for example, Android or iOS) and that controls all of the low-level timing-dependent functions of the mobile device.
Data Synchronisation
The process of automatically merging and updating common data that is stored on multiple devices.
Digitiser
On touch screen displays, a layer of sensors between the LCD display and a layer of glass that enables the translation of the analogue touch signal to a digital signal.
Discovery Mode
A device mode that will transmit a friendly signal to another device in close proximity.
Docking Station
Desktop devices that connect portable computers to standard desktop peripherals without the need to connect and disconnect the peripherals themselves when the user switches from stationary to mobile use.
EAS (Exchange ActiveSync)
Microsoft’s synchronisation protocol that enables mobile devices to connect to an Exchange Server to access mail, calendar, and contacts.
ExpressCard
A mobile expansion card designed by the PCMCIA to replace traditional PC Cards to provide PCI Express and USB 2.0 connectivity.
Frontlight
A form of lighting devices from the front of the display.
Ghost Cursor
A cursor that jumps around on the screen randomly, or moves too slow, or opens windows and menus on its own.
IMAP4 (Internet Mail Access Protocol)
A protocol used to retrieve email messages and folders from a mail server.
IMEI Number (International Mobile Equipment Identity)
A number that uniquely identifies a mobile device.
IMSI Number (International Mobile Subscriber Identity)
A number that uniquely identifies a mobile subscriber.
Inverter
A laptop component that converts DC power to AC power for the display.
IPS (In-Plane Switching)
An LCD panel technology designed to resolve the quality issues inherent in TN panel technology, including strong viewing angle dependence and low-quality colour reproduction.
Laptop
A complete computer system that is small, compact, lightweight, and portable.
MicroDIMM (Micro Dual Inline Memory Module)
A memory module standard used in some laptops.
Mini-PCIe (PCI Express Mini Card)
An extremely small expansion card, often just a few centimetres in length, used to increase communication abilities by providing network adaptors or modems and supports various connections and buses.
Multitouch
The technology used on the surface of the touch screen on tablets and other mobile devices that can recognise more than one contact on the surface at once.
OLED Display (Organic Light Emitting Diode)
A type of LED flat panel display device that uses organic compounds that emit light when subjected to an electric current.
Pairing
The process two devices use to establish a wireless connection through Bluetooth.
Plastics
The hard surfaces that protect the internal components of a laptop.
Pointer Drift
A situation where the mouse pointer moves across the screen without the user touching the touchpad or mouse.
POP3 (Post Office Protocol version 3)
A protocol used to retrieve email from a mailbox on the mail server.
Port Replicator
A scaled-down version of a docking station with only the standard ports available.
PRI (Preferred Roaming Index)
An index that works with the PRL to provide the best data/voice quality to a phone while roaming.
PRL (Preferred Roaming List)
A database built by CDMA service carriers to indicate which radio bands should be used when connecting to a cell tower.
Radio Firmware
In a mobile device, memory that contains an operating system that is separate from the end-user operating system (for example, Android or iOS) and that controls all of the low-level timing-dependent functions of the mobile device.
Smart Camera
A digital camera that includes a processor, memory, cellular and Wi-Fi support, and a mobile operating system.
Smart Watch
A multipurpose device that runs computing applications and that is worn on a person’s wrist.
Smartphone
A mobile digital device that combines the functionality of a portable phone with that of media players, GPS navigation units, personal digital assistants, and cameras.
SODIMM (Small Outline Dual In-Line Memory Module)
Memory that is half the size of DIMMs, are available in 32- or 64-bit data paths, and are commonly found in laptops and iMac systems.
Soldered
A means of securing electronic components to a circuit board by using a combination of lead, tin, and silver (solder) and a tool called a soldering iron,
TFT (Thin Film Transistor)
A display type commonly used in laptops.
