mobile devices Flashcards
Mobile Device
▪ Any device that makes it portable and easy to use
Capacitive Touch Screen
-mobile displays
▪ Any touchscreen that works by seeing the distortion in an electrostatic field
▪ A single tactile input is one touch at a time
Multi-Touch Screen
-mobile displays
▪ Can process two or more contact points simultaneously
Liquid-Crystal Display (LCD)
-mobile displays
▪ Uses liquid crystal where the properties can change with the application of voltage
Pixel (Picture Element)
-mobile displays
▪ Individual point on a screen inside of a display
▪ A thin-film transistor (TFT) is referred to as an LCD panel
Twisted Nematic (TN)
-mobile displays
▪ Contains crystals that twist or untwist in response to the voltage being applied or removed
▪ TN supports fast response time in comparison to other TFT technologies and displays
In-Plane Switching (IPS)
-mobile displays
▪ Uses crystals that rotate to be able to deliver color
▪ IPS panels can support 178° horizontal and vertical viewing angles
Vertical Alignment (VA)
-mobile displays
▪ Crystals are tilted to be able to deliver color
▪ A VA display has a contrast ratio of two to three times better than a standard IPS display
Cold Cathode Fluorescent Lamp (CCFL)
-mobile displays
▪ Lamp that sits behind the display and lights up the liquid crystal display to
show the colors and images properly on the screen
▪ CCFL requires AC voltage
Light-Emitting Diode (LED)
-mobile displays
▪ Newer form of light that uses direct current (DC)
▪ The use of LEDs uses less power, leading to longer battery life and better
performance
Organic LED (OLED)
-Mobile Displays
▪ Each pixel has its own separate LED that provides the light
▪ OLEDs can be made from plastic
▪ OLEDs can be folded, rolled up, or manipulated to create different shapes and sizes of displays
Digitizer
-Mobile Displays
▪ Layer sandwiched between a layer of protective glass and the display panel inside of a touchscreen display
▪ Haptic feedback provides a form of touch responsiveness from the display back to the end-user
Accelerometer
▪ Combination device that uses hardware and software to measure the velocity, rotation, and shaking of a mobile device
▪ The accelerometer works when dealing with the X (horizontal) and Y (vertical) axis
Gyroscope
▪ An improved version of the basic accelerometer
● Detects pitch (Y), roll (X), and yaw (Z)
● Performs actions
● Stabilizes images
Code-Division Multiple Access (CDMA)
▪ Cellular technology that uses code division to split up the channel
▪ CDMA is a more powerful and flexible technology than GSM
Preferred Roaming List (PRL)
▪ Contains all the information about different cellular towers
▪ Restrictions vary from model to model and depends on the device’s country of origin
Port Replicator
▪ Uses the exact same features as a laptop
▪ Port replicator makes life easier by providing easier access to all of the ports
Docking Station
▪ Advanced type of port replicator that provides all the capabilities and features of a laptop
Port Replicator
▪ Uses the exact same features as a laptop
▪ Port replicator makes life easier by providing easier access to all of the ports
POP3
▪ Oldest format and does not support the synchronization across devices (e-mail)
Synchronization to the Cloud
▪ Provides the access to the cloud from all devices and becomes the central repository of all data
▪ Encrypted data that is stored in the cloud is relatively safe
▪ Synchronization to the cloud requires a large amount of data
Synchronization to the Computer
▪ Synchronizes directly to the desktop or laptop using a USB or Bluetooth connection
▪ Install the iTunes app on the Windows PC to transfer the data from the iPhone
Enterprise Mobility Management (EMM)
▪ Class of software designed to apply security policies for use on mobile devices
Mobile Device Management (MDM)
▪ Sets device-level policies for authentication, feature use, and conductivity
▪ MDM is a type of software that allows to control the device
Mobile Application Management (MAM)
▪ Sets forth policies for apps that can process corporate data and prevent data transfer to personal apps
Sandbox Solution
▪ Configures an enterprise-managed container or workspace where the company’s data is stored
Data Loss Prevention (DLP)
▪ Detects when data is being taken from a device, ensuring it’s only being used in the proper way
Apple Business Manager (ABM)
▪ MAM suite that allows applications from a private repository to devices that are part of the corporate network
POP3/IMAP
▪ Receiving email/Inbound mail
STMP
▪ Sending/Outbound mail
▪ Major providers like Gmail, Outlook, or Yahoo use auto configuration
▪ Small or medium-sized businesses use their own institutional email server
Transport Layer Security (TLS)
▪ New and advanced secure version of encryption
