Describe how Android apps are distributed.

Android apps are sold or freely distributed from any source or vendor. However, the official source for apps, called the Android marketplace, is Google Play at play.google.com. To download content, you need a Google account, which you can set up using the web site or your device. The account is associated with any valid email address. Associate a credit card with the account to make your purchases at Google Play. Then you can purchase or download free music, books, movies, and Android apps from Google Play to your mobile device.

C

What is cloud computing an list three types of cloud computing services.

Cloud computing is when server-side virtualization is delegated to a third-party service, and the Internet is used to connect server and client machines. Infrastructure as a Service (IaaS). Platform as a Service (PaaS). Software as a Service (SaaS).

A setting called airplane mode lowers the output power of the Wi-Fi and Bluetooth antennas allowing these networks to function, but at a reduced range.

False

You usually install an OS on a mobile device using a USB device or SD-card.

False

A cloud-computing service that provides only the hardware, which can include servers, Network-attached Storage (NAS) devices, and networks

IaaS

Define open source as it pertains to operating systems.

Open source means the source code for the operating system is available for free and anyone can modify and redistribute the source code. Open source software is typically developed as a community effort by many contributors.

A cloud-computing service that provides hardware and the operating systems and is responsible for updating and maintaining both

PaaS

Describe how to make a Bluetooth connection from a mobile device to another device.

To configure a Bluetooth connection, first turn on the other Bluetooth device you want to connect to. Then on your mobile device, tap Settings, General, Bluetooth. On the Bluetooth screen, turn on Bluetooth. The device searches for Bluetooth devices. If it discovers a Bluetooth device, tap it to connect. The two Bluetooth devices now begin the pairing process. The devices might require a Bluetooth PIN code to complete the Bluetooth connection. To complete the connection, enter the 4-digit PIN on the keyboard.

The Android OS is based on Linux.

True

VMs running under a Type 1 hypervisor are isolated from each other.

True

The process of connecting with another Bluetooth device

pairing

When moving a VM from one computer to another, be sure the files are secured with ______________ that allow access only to specific users.

permissions or file permissions

How are apps for iOS distributed?

Apple is the sole distributor of iOS apps at its iTunes App Store (itunes.apple.com). Other developers can write apps for the iPhone, iPad, or iPod, but these apps must be sent to Apple for their close scrutiny. If they pass muster, they are distributed by Apple on its web site.

a computer that has an operating system, but has little computing power and might only need to support a browser used to communicate with the server

thin client

Describe the two primary technologies used for mobile device touch interfaces.

A touch screen uses resistive or capacitive technologies. A capacitive touch screen uses electrodes that sense the conductive properties of skin. A resistive touch screen has two sheets of glass covered with a resistive coating. The two sheets are kept from touching by spacers between them. When pressure is placed on the top glass, the glass bends and makes contact with the lower glass.

What must you do before using a new iPad or iPod touch? a. register it b. activate it c. install iOS on it d. install iTunes on it

B

Which of the following is a screen that uses electrodes that sense the conductive properties of skin? a. dual-touch screen b. capacitive touch screen c. pressure-sensing screen d. resistive touch screen

B

Which type of device is most likely to have a slot for an SD card? a. iPod Touch b. Android smart phone c. iPhone d. iPad

B

A SIM card is used for which of the following? a. holding data related to your cellular carrier b. holding your iTunes music information c. controlling the sensitivity of your touch screen d. backing up your data and applications

A

What is the accelerometer used for in mobile devices? a. adjusting the screen orientation b. geotracking c. synchronizing data d. locating the nearest cell tower

A

Which of the following is based on open source code? a. Android b. Blackberry c. Windows Phone d. iOS

A

Which component on a smart phone requires pairing with another device? a. GPS b. WiFi c. Bluetooth d. SIM card

client-side virtualization

On Android phones, up to four apps can be pinned to the __________ at the bottom of the screen.

dock

A device that contains a disc that is free to move and can respond to gravity as the device is moved

gyroscope

Software to create and manage virtual machines on a server or on a local computer

hypervisor

a remote application running on a server is controlled by a local computer

A

Define a Type 1 hypervisor and give two examples of a Type 1 hypervisor.

A Type 1 hypervisor installs on a computer before any operating system, and is, therefore, called a bare-metal hypervisor. After it installs, it partitions the hardware computing power into multiple VMs. An OS is installed in each VM. Examples of Type 1 hypervisors are XenServer by Citrix, ESXi by VMware, and Hyper-V by Microsoft.

Which of the following are physical buttons on the front of Android smart phones. (Choose all that apply.) a. Menu b. Call c. Go Back d. Web

A,B

Which of the following are requirements/recommendations for installing a hypervisor and VMs? (Choose all that apply.) a. hardware assisted virtualization b. 2 GB virtual memory for each VM c. virtual network driver d. 15 GB free hard drive space for each Windows VM

A,D

List two advantages and two disadvantages of using server-side virtualization.

Advantages: Maximize a company's investment in hardware. Centralize support for hardware, software, and users. Disadvantages: High-end servers are required and network load increases. User experience might suffer.
