Back 7

Keylogger

Front 8

A program that copies itself throughout, a network or the internet without a host program. It creates problems by overloading the network as it replicates and can even hijack or install a server program.

Back 8

Worm

Front 9

Does not need a host program to work; rather it substitutes itself for a legitimate program. Often downloaded from a web site when a user is tricked into thinking it is legitimate software, or tricked into opening an email attachment.

Back 9

Trojan

Front 10

A virus that loads itself before the OS boot is complete. It can hide folders that contain software it has installed and can hijack internal Windows components so that it makes information Windows provides to user mode utilities such as Task Manager, Windows explorer, the registry editor, and antivirus software.

HTC Sense

Front 13

A multi-touch technology developed by High Tech Computer and widely used by mobile devices.

TouchFLO

Front 14

A device that has no parts for in field repairs. It is not possible to upgrade or replace internal components without having to shop online for them.

Back 14

Field-replaceable units (FRU)

Front 15

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

Back 15

Gyroscope

Front 16

Disables all three antennas, so a device can neither transmit nor receive signals.

Back 16

Airplane Mode

Front 17

When one physical machine hosts multiple activities that are normally done on multiple machines.

Back 17

Virtualization

Front 18

Using this virtualization, a server provides a virtual desktop or application for users on multiple client machines.

Back 18

Sever-Side Virtualization

Front 19

A presentation of a virtual desktop made to a client computer by a server that is serving up a virtual machine.

Back 19

Virtual Desktop Infrastructure

Front 20

Based on the computing power of the client; what are the three categories of clients used in server-side virtualization?

Back 20

Fat Client

Thin Client

Zero Client

Front 21

The main advantage of using this type of client is the personal computer can be used for other purposes than server-side virtualization.

Back 21

Fat Clients

Front 22

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

Back 22

Thin Clients

Front 23

Does not have an operating system and merely provides an interface between the user and the server. It contains little more than a keyboard, mouse, monitor, and network connection - used to further reduce the cost of a client machine.

Back 23

Zero client

Front 24

When server-side virtualization is delegated to a third-party service, and the internet is used to connnect server and client machines.

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

Back 26

Platform as a Service (PaaS)

Front 27

A cloud computing service where the service is responsible for the hardware, the operating systems, and the applications installed.

Back 27

Software as a Service (SaaS)

Front 28

Using this virtualization, a virtual environment is created in memory for an application to virtually install itself.

Back 28

Application virtualization

Front 29

Using this virtualization, software installed on a desktop or laptop manages virtual machines used by the local user.

Back 29

Client-side desktop virtualization

Front 30

Motherboard BIOS and processor support used by hypervisor software when it creates and runs virtual machines on a computer. The feature must be enabled in BIOS setup.

Back 30
